Understanding Science

How science REALLY works...

• Understanding Science 101
• Misconceptions

Misconception: Science is a collection of facts.

Correction: Science is both a body of knowledge and the process for building that knowledge. Read more about it.

What is science?

The word “ science ” probably brings to mind many different pictures: a fat textbook, white lab coats and microscopes, an astronomer peering through a telescope, a naturalist in the rainforest, Einstein’s equations scribbled on a chalkboard, the launch of the space shuttle, bubbling beakers …. All of those images reflect some aspect of science. But none of them provides a full picture because science has so many facets:

• Science is both a body of knowledge and a process. In school, science may sometimes seem like a collection of isolated and static  facts listed in a textbook, but that’s only a small part of the story. Just as importantly, science is also a process of discovery that allows us to link isolated facts into coherent and comprehensive understandings of the natural world .
• Science is exciting. Science is a way of discovering what’s in the universe and how those things work today, how they worked in the past, and how they are likely to work in the future. Scientists are motivated by the thrill of seeing or figuring out something that no one has before.
• Science is useful. The knowledge generated by science is powerful and reliable. It can be used to develop new technologies , treat diseases, and deal with many other sorts of problems.
• Science is ongoing. Science is continually refining and expanding our knowledge of the universe, and as it does, it leads to new questions for future investigation. Science will never be “finished.”
• Science is a global human endeavor. People all over the world participate in the process of science. And you can too!

What is science—and why does it matter?

by Chris Woodford . Last updated: January 4, 2022.

Q uestions, questions. Why this...? Why that...? How does this...? How come that...? If you're the sort of person who's always seeking answers, maybe you're a scientist of sorts without knowing it? Knowing , in fact, is what science is all about: the term "science" is linked to Latin words like scire ("to know") and scientia ("knowledge"), so it's the process of finding answers to how and why the world works as it does. From why the sky's blue to how your nose smells, from why boats float on water to what makes us happy or sad , you can seek answers—and enlightenment— in all kinds of ways: you can ask your friends their opinion, pray to a god, paint pictures, write songs, or meditate on a mountain, scratching your head. What makes science so different from these other ways of thinking about things—and why does it matter?

What is science?

What makes science different is that it's a very systematic way of building up knowledge. It uses logical thinking to explain why things work or how things happen based on evidence gathered through observation and experiment. Slowly and surely, science comes up with coherent explanations called theories that mesh with bigger theories to make ever more comprehensive accounts of what's going on around us. So, for example, Isaac Newton's comprehensive, "universal" theory of gravity was built on smaller theories like Galileo's observations of how falling objects hurtle toward Earth and Johannes Kepler's ideas about the planets sweeping through space, themselves based on earlier science dating back to ancient times. Newton's ideas, in turn, became part of a wider explanation of gravity, known as the general theory of relativity, which Albert Einstein put forward in the early 20th century. Science is a jigsaw puzzle, the theories are the pieces, and as different theories gradually lock together, they give us an ever-expanding picture of how our world works.

The scientific method

“ The important thing is not to stop questioning. ” Albert Einstein

Why's the sky blue? If you don't know the actual explanation, you could probably guess at all sorts of answers—and so could everyone else. If we just asked people what they thought, we could easily end up with 50 or 500 possible accounts. How do we figure out which of these is the right one?

Scientists use an approach called the scientific method . First, they observe or measure something (the sky being blue, for example) very carefully and systematically, which is known as gathering data. (When is it blue? Precisely what shade of blue? Is it ever other colors? When?) From this, they come up with a tentative, logical explanation known as a hypothesis . (It could be something like: the sky is blue because there's water in the air.) The hypothesis should suggest ways in which it can be tested, which are known as experiments . (Is the sky blue on cloudy days, when there's apparently more water in the sky, or dry days, when it's sunnier?) By carrying out experiments, a scientist can test a hypothesis to see if it's a good explanation that accounts for all the evidence.

Although experiments can be quick and simple, they can also be intricate and complex. Most experiments compare a situation where we've deliberately changed something (say, doing more exercise to see if we feel better) with another situation where we haven't. That's called a controlled experiment and it allows us to see whether the thing we change makes any difference. (We can do other experiments that change other things, one at a time, and see what difference that makes instead.) Experiments that come up with mathematical results also have to prove that those results couldn't have happened purely by chance. There are ways of testing experimental data using math and if the data is better than a chance result, we say it's statistically significant .

If a hypothesis can't be tested by experiment, it's usually rejected as bad science from the start. So if your idea of why the sky is blue is that Martians got out their paint pots when you weren't looking, that's essentially untestable: there's no evidence and no obvious way of getting any, so the hypothesis is a non-starter. That doesn't mean a hypothesis has to be tested immediately: sometimes it takes quite a while to devise just the right experiment. Albert Einstein first put forward his general theory of relativity in 1915. But he had to wait four years before another physicist, Sir Arthur Eddington, was able to confirm it , with the help of a famous solar eclipse.

“ Science is a method to keep yourself from kidding yourself. ” Edwin Land

Why is evidence so important to science? Medicine is probably the best example. If you're sick, you want an effective treatment that makes you better; if you're dying, you want a cure. It's perfectly possible that quack cures will sometimes help people get better, either through pure chance or the very intriguing (and very real) placebo effect . But to come up with medical treatments that consistently improve people's lives, we need to carry out experiments and build up evidence that those treatments really do work, consistently, and in all the different groups of people who might try them; we also need to be sure they don't do more harm than good. Science stops us falling into the trap of gullibility—of believing specious ideas (things that sound right that are actually wrong). As Edwin Land, the physicist inventor of the Polaroid camera once said: "Science is a method to keep yourself from kidding yourself."

What is a theory?

If there's good evidence, a tentative and very fluid hypothesis starts to solidify into a more formal, generally accepted explanation of something, which is called a theory . In other words, a theory is a hypothesis confirmed by experimental evidence or other observations. The more and better the evidence, the stronger the theory—and the more things a theory can explain, the better it is. Importantly, evidence for a theory has to come from more than one person or group: in other words, the results of one team's work has to be replicated (repeated) by others. Theories also have to be published and discussed by the wider scientific community (usually in reputable scientific journals) in a process known as peer review , which gives other people the opportunity to spot flaws in your theory or the methods you used to test it. If any evidence contradicts a theory, the theory is either wrong or incomplete, which means a better theory is needed. Sometimes wrong theories come from bad experiments that supply incorrect data or other kinds of misleading evidence. It's important to try to disprove theories ("If we see this happening, the theory must be wrong") and not just confirm them ("If we see this happening, it agrees with our theory"), though it's a sign of a good theory if it can be properly defended against criticism.

The best theories—things like the theory of evolution —have "evolved" (if you'll excuse the pun) over decades or centuries, supported by many different kinds of evidence involving thousands of experiments and studies by many different scientists from all sorts of fields. It can take a long time for an excellent theory like this to be accepted. In much the same way, wrong-headed theories will sometimes take a long time to disappear. For example, it was originally believed that Earth was the center of the universe and the Sun and planets revolved around it. Known as the geocentric theory (literally, "Earth-centered" theory), that was widely accepted in ancient times, but evidence slowly emerged that it was wrong. To get around this, early scientists could simply have thrown that theory away and come up with a totally new one. Instead, what they did was come up with increasingly tortuous fudges to account for the discrepancies. Eventually, scientists like Kepler, Galileo, and Copernicus developed a rival heliocentric theory , in which the Sun sits at the center of things, which is what people believe today. Another commonly believed explanation that lasted a very long time was the miasma theory —the idea that diseases were passed on by bad air. It persisted as a plausible explanation of disease from ancient times right up until the late 19th century, when growing evidence led to a much better explanation known as the germ theory (the idea that bacteria and viruses cause diseases).

Photo: Albert Einstein's theory of relativity wasn't just his throwaway "opinion": it was a explanation designed to account for all the facts Einstein knew about things like light, gravity, and motion. Photo courtesy of US Library of Congress .

It's important to realize that calling something "a theory" doesn't mean it's flaky, speculative, or just an opinion. The theory of evolution is supported by a huge mass of very different evidence and, though there are still gaps in our understanding of how it works, it's generally accepted as the best explanation of how the modern pattern of humans and other living creatures came to arrive on Earth. In other words, it's the best explanation for all the facts that we have. Einstein's original, "special" theory of relativity was also supported by evidence, but there were various things it couldn't explain. That was why Einstein soon developed a deeper, more comprehensive explanation in the shape of his "general" theory of relativity. This, too, has gaps and is by no means a perfect theory (for example, it's an ongoing challenge to reconcile Einstein's ideas with quantum theory, the currently favored explanation of how the atomic world works). Crucially, no scientific theory can ever be proved completely correct: someone could always come up with new evidence tomorrow that disproves it. But that doesn't mean every theory is automatically suspect. If a theory has been around a long time and it's supported by a huge body of different evidence (like the theory of evolution), we can be reasonably confident that it's right. Even so, as the heliocentric theory shows, we can never be complacent: as scientists, our minds should always be open. The key point is that science is a work in progress; it's like a vast jigsaw puzzle that will never be complete.

“ Some claim that evolution is just a theory, as if it were merely an opinion. The theory of evolution—like the theory of gravity—is a scientific fact. ” Richard Dawkins

Types of science

If science is a method —a way of building knowledge about the world—that suggests it's a kind of tool we can apply to all kinds of things. From physics and chemistry to medicine and sociology, scientific methods have been used to study every aspect of our world. Different sciences are very different from one another and range from the highly abstract, mathematical ideas of theoretical physics to the very concrete ideas of medical science, which are firmly grounded in biological observations of how our bodies work.

Science and its rivals

The scientific method—and the fundamental importance of evidence—is the big difference between science and other ways of thinking about our place in the world, including myths, superstitions, art, religion, and things like astrology. You might be a superstitious kind of person who doesn't walk on the cracks in the pavement, but there's no evidence that walking on cracks is either bad or good for you in any way—and no obvious mechanism by which it ever might be. Myths and superstitions may be fascinating and fun, but they're not credible explanations that can compete with science.

Can religion, art, or myth explain things like this?

Science versus religion?

What about religion? It's perfectly fine to have religious beliefs about why we see colors in the sky or to paint a picture that shows a rainbow forming, but art and religion are a world away from scientific explanations. They might even be based on meticulous observations, but they still lack the logical rigor of scientific theories. You might say "Well, a religious miracle is evidence for [such and such]," but that's hardly a scientific explanation. Miracles aren't testable, they're not repeatable, and they generally have other, more scientific explanations behind them. That's not to say that religion has no value; the value it has as a coherent belief system, which helps people to live morally good, spiritually enriched, happy and fulfilled lives, is very different from the value of science. You can pray, if you have lung cancer, and it could help you in all kinds of ways—but medical treatments, based on years of evidence-based research, are much more likely to cure you.

Science and art

“ To develop a complete mind: Study the science of art; Study the art of science. Learn how to see. Realize that everything connects to everything else. ” Leonardo da Vinci

When people are studying in schools and colleges, they often think of themselves as "arty" or "sciencey," as though there's a sharp line between the two. Arts subjects are meant to be more human, creative, poetic, emotional, and romantic; sciences are considered more logical, rational, methodical, prosaic, and perhaps even a bit plodding and boring. Of course, that's all a matter of opinion: it's hard to think of anything more human than medicine, for example, which is quintessentially scientific. It's never really clear why people want to build high walls between the arts and sciences. A genius like Leonardo da Vinci obviously straddled the divide; modern artists and scientists also work on similar or overlapping problems. You could argue, for example, that, with their pursuit of cubism, artists like Cezanne, Braque, and Picasso were studying very similar problems to scientists like Einstein. Bridget Riley's op-art clearly has much in common with a branch of psychology called psychophysics (which studies how the eyes and brain perceive light, colors, and patterns). Artist Josef Albers was just as much a scientist of color as Isaac Newton or Thomas Young. Less obviously, a sculptor like Rodin was arguably just as preoccupied with gravity (in his own way) as a scientist like Galileo or Newton.

The very short story of science

How did humans come up with the idea of science? What was wrong with myths, superstitions... and all those earlier, older, and often more magically enchanting ways of explaining? Science, ultimately, turned out to be a more successful intellectual engine for powering civilization. It had better answers and more useful explanations; it soon pulled ahead of the pack. It's easy to see why with an example. In hindsight, it's clear how a growing scientific understanding of electricity and magnetism in the 18th and 19th centuries enabled the development of a superb new way of harnessing, storing, and using energy that's been revolutionizing our world ever science. By contrast, it's hard to see how mystical, mythical, religious, or superstitious ways of explaining things like static electricity , lightning, or sparks could ever have spawned such fabulously useful technologies as electric cars or computers . They might be very comforting to people, as self-contained explanations of a kind, but they offer no real value going forward.

Before science

Early civilizations had systematic knowledge—astronomy and math were their strongest suits—but they didn't have what we now regard as science. People certainly made discoveries—fire, for example—and they came up with world-beating inventions like the wheel and axle . They could see those things were effective, but they didn't understand how or why (how a fire burst to life or exactly why a wheel made it easier to push a cart). Nor did they appreciate how one discovery could couple with another to make a third that was even more useful (how a fire could be used to drive a wheel—which was the thinking behind steam engines ). Early people knew how to extract metals like gold and silver from the Earth and how to refine them, but they didn't understand the relationship between different elements or the chemistry of how they combine, which is why they got sidetracked by absurd ideas like alchemy. Knowledge, such as it existed, tended to be practical rather than theoretical and very much more fragmented.

Ancient science

Science was really born in ancient times, with the Sumerians, Egyptians, and Greeks like Thales, Pythagoras, Anaximander, Aristotle, Archimedes, and Eratosthenes. Infatuated with logical reasoning and mathematics, they had both qualitative ("wordy") and quantitative ("numbery") explanations for things. The scientific foundations of physics, botany, zoology, anatomy, physiology, engineering, and medicine were all laid down in ancient times. The Romans who followed the Greeks were, by contrast, more practical and applied scientists, making huge leaps in architecture and engineering.

Dark and Golden science

“ Arabic science throughout its golden age was inextricably linked to religion; indeed, it was driven by the need of early scholars to interpret the Qur'an. ” Jim Al-Khalili

Following the collapse of the Roman Empire, scientific progress stalled in the west, in a time known as the Dark Ages, while the baton of progress passed to the Islamic world in a glorious period of science history now known as the Islamic Golden Age . Al-Khwarizmi (who gave his name to algorithms) developed algebra, Avicenna advanced medicine, Alhazen pioneered modern optics, and Al-Jazari developed ingenious machines. In the Arabic world, the best ideas from Egypt, Greece, China, India, and elsewhere fused and burned like the fuel in a modern-day rocket, before drifting back to Europe at the end of the Middle Ages. Science, in the Golden Age, helped to illuminate religion. And from then on, religious and philosophical ideas slowly started to merge with scientific ones thanks to the enlightened open minds of scholars like Peter Abelard, Thomas Aquinas, Hildegard of Bingen, and Roger Bacon.

The science revolution

True science probably began at the point where the world's best thinkers started to toss aside ancient ideas. Leonardo da Vinci blurred the boundaries between art and science, as never before or science. Another defining figure was Nicolaus Copernicus, who, as we've already seen, challenged the long-held (and religiously defended) idea that God's Earth anchored a "geocentric" Universe. Meanwhile, Belgian Andreas Vesalius published a detailed anatomical textbook superseding the ancient, out-of-date medical ideas of Galen and Avicenna. And Francis Bacon helped to formalize the scientific method.

Copernicus paved the way for Kepler and Galileo, who, in turn, opened the door for Isaac Newton and his insightful theories of gravity , motion , light , and a superb mathematical tool known as calculus (developed in parallel by German polymath Gottfried Leibniz). Meanwhile, Robert Hooke studied plants, animals, and living cells under the microscope , while William Harvey built on Vesalius's work with a pioneering theory of how blood circulates around our bodies and hugely influential ideas about magnetism. Another Robert, Robert Boyle, kick-started the systematic, experimental study of chemistry.

Modern science

In physics, thanks to a steady stream of pioneers from Benjamin Franklin to Michael Faraday, the 18th and 19th centuries were the age of electricity and energy, a fusion of practical and applied ideas, science spawning technology. Over in chemistry, magical ideas like alchemy (which even Newton had toyed with) gave way to more realistic, systematic explanations based on a gradual understanding of the chemical elements as fundamental building blocks of our world. Two key figures here were Frenchman Antoine Laurent Lavoisier, who figured out the logic of how elements fused together in reactions, and Englishman John Dalton, who sketched out the beginnings of our modern atomic theory (the idea that everything is ultimately made of atoms). Their ideas would help Dmitri Mendeleev to figure out how elements related to one another in a theoretical diagram he drew up known as the Periodic Table. Meanwhile in biology, a Swedish botanist named Carl Linnaeus studied the similarities and differences between plants and animals and worked out a neat, hierarchical system of classifying species that we still use to this day. A little later, Gregor Mendel pioneered genetics (the idea that plants and animals inherit important characteristics from their parents). The work of Linnaeus and Mendel held the door wide for Charles Darwin and his life-explaining theory of evolution by "natural selection."

These seeds of modern biology spawned amazing new advances in the 20th century, most notably with Francis Crick and James Watson's discovery of the structure of DNA in 1953, and Frederick Sanger's pioneering work on DNA sequencing. But the 20th century saw many other huge advances, from Einstein's world-bending theory of relativity to Edwin Hubble's idea of the ever-expanding universe. The biggest, most revolutionary advances arguably came with a much deeper understanding of the atomic theory, with discovery piled upon discovery by such brilliant physicists as Ernest Rutherford, Niels Bohr, Lise Meitner, Enrico Fermi, Richard Feynman, and many others. Practical spin-offs of this work included everything from nuclear power plants to superconductors and supercomputers .

The power of science

And this is how the story of science moves forward. Each theory builds on older theories, adjusts them, improves them, or kicks them entirely aside. Theories interlock with other theories, making bigger, better, and more comprehensive explanations. We learn more and more about the world and our place in it, how to solve pressing problems, how to do things better, quicker, or in less environmentally destructive ways. Time moves on, the world moves with it. But thanks to the power of science, humans always move forward , to a better place.

What Is a Science Essay?

A science essay is an academic paper focusing on a scientific topic from physics, chemistry, biology, or any other scientific field.

Science essays are mostly expository. That is, they require you to explain your chosen topic in detail. However, they can also be descriptive and exploratory.

A descriptive science essay aims to describe a certain scientific phenomenon according to established knowledge.

On the other hand, the exploratory science essay requires you to go beyond the current theories and explore new interpretations.

So before you set out to write your essay, always check out the instructions given by your instructor. Whether a science essay is expository or exploratory must be clear from the start. Or, if you face any difficulty, you can take help from a science essay writer as well. 

Moreover, check out this video to understand scientific writing in detail.

Now that you know what it is, let's look at the steps you need to take to write a science essay. 

Paper Due? Why Suffer? That's our Job!

How To Write a Science Essay?

Writing a science essay is not as complex as it may seem. All you need to do is follow the right steps to create an impressive piece of work that meets the assigned criteria.

Here's what you need to do:

Choose Your Topic

A good topic forms the foundation for an engaging and well-written essay. Therefore, you should ensure that you pick something interesting or relevant to your field of study. 

To choose a good topic, you can brainstorm ideas relating to the subject matter. You may also find inspiration from other science essays or articles about the same topic.

Conduct Research

Once you have chosen your topic, start researching it thoroughly to develop a strong argument or discussion in your essay. 

Make sure you use reliable sources and cite them properly . You should also make notes while conducting your research so that you can reference them easily when writing the essay. Or, you can get expert assistance from an essay writing service to manage your citations. 

Create an Outline

A good essay outline helps to organize the ideas in your paper. It serves as a guide throughout the writing process and ensures you don’t miss out on important points.

An outline makes it easier to write a well-structured paper that flows logically. It should be detailed enough to guide you through the entire writing process.

However, your outline should be flexible, and it's sometimes better to change it along the way to improve your structure.

Start Writing

Once you have a good outline, start writing the essay by following your plan.

The first step in writing any essay is to draft it. This means putting your thoughts down on paper in a rough form without worrying about grammar or spelling mistakes.

So begin your essay by introducing the topic, then carefully explain it using evidence and examples to support your argument.

Don't worry if your first draft isn't perfect - it's just the starting point!

Proofread & Edit

After finishing your first draft, take time to proofread and edit it for grammar and spelling mistakes.

Proofreading is the process of checking for grammatical mistakes. It should be done after you have finished writing your essay.

Editing, on the other hand, involves reviewing the structure and organization of your essay and its content. It should be done before you submit your final work.

Both proofreading and editing are essential for producing a high-quality essay. Make sure to give yourself enough time to do them properly!

After revising the essay, you should format it according to the guidelines given by your instructor. This could involve using a specific font size, page margins, or citation style.

Most science essays are written in Times New Roman font with 12-point size and double spacing. The margins should be 1 inch on all sides, and the text should be justified.

In addition, you must cite your sources properly using a recognized citation style such as APA , Chicago , or Harvard . Make sure to follow the guidelines closely so that your essay looks professional.

Following these steps will help you create an informative and well-structured science essay that meets the given criteria.

How to Structure a Science Essay?

A basic science essay structure includes an introduction, body, and conclusion. 

Let's look at each of these briefly.

• Introduction

Your essay introduction should introduce your topic and provide a brief overview of what you will discuss in the essay. It should also state your thesis or main argument.

For instance, a thesis statement for a science essay could be, 

"The human body is capable of incredible feats, as evidenced by the many athletes who have competed in the Olympic games."

The body of your essay will contain the bulk of your argument or discussion. It should be divided into paragraphs, each discussing a different point.

For instance, imagine you were writing about sports and the human body. 

Your first paragraph can discuss the physical capabilities of the human body. 

The second paragraph may be about the physical benefits of competing in sports. 

Similarly, in the third paragraph, you can present one or two case studies of specific athletes to support your point. 

Once you have explained all your points in the body, it’s time to conclude the essay.

Your essay conclusion should summarize the main points of your essay and leave the reader with a sense of closure.

In the conclusion, you reiterate your thesis and sum up your arguments. You can also suggest implications or potential applications of the ideas discussed in the essay. 

By following this structure, you will create a well-organized essay.

Check out a few example essays to see this structure in practice.

How to Choose the Right Science Essay Topic

Choosing the right science essay topic is a critical first step in crafting a compelling and engaging essay. Here's a concise guide on how to make this decision wisely:

• Consider Your Interests: Start by reflecting on your personal interests within the realm of science. Selecting a topic that genuinely fascinates you will make the research and writing process more enjoyable and motivated.
• Relevance to the Course: Ensure that your chosen topic aligns with your course or assignment requirements. Read the assignment guidelines carefully to understand the scope and focus expected by your instructor.
• Current Trends and Issues: Stay updated with the latest scientific developments and trends. Opting for a topic that addresses contemporary issues not only makes your essay relevant but also demonstrates your awareness of current events in the field.
• Narrow Down the Scope: Science is vast, so narrow your topic to a manageable scope. Instead of a broad subject like "Climate Change," consider a more specific angle like "The Impact of Melting Arctic Ice on Global Sea Levels."
• Available Resources: Ensure that there are sufficient credible sources and research materials available for your chosen topic. A lack of resources can hinder your research efforts.

Essays About Science: Top 12 Examples and Prompts

Science can explain almost every aspect of our lives; if you want to write essays about science, start by reading our guide.

The word “science” comes from the Latin word Scientia or “knowledge,” It does indeed leave us with no shortage of knowledge as it advances to extraordinary levels. It is present in almost every aspect of our lives, allowing us to live the way we do today and helping us improve society. 

In the 21st century, we see science everywhere. It has given us the technology we deem “essential” today, from our mobile phones to air conditioning units to lightbulbs and refrigerators. Yet, it has also allowed us to learn so much about the unknown, such as the endless vacuum of space and the ocean’s mysterious depths. It is, without a doubt, a vehicle for humanity to obtain knowledge and use this knowledge to flourish. 

To start writing essays about science, look at some of our featured essay examples below. 

1. The challenging environment for science in the 21st century by Nithaya Chetty 

2. disadvantages of science by ella gray, 3. reflections from a nobel winner: scientists need time to make discoveries by donna strickland.

• 4.  ​​The fact of cloning by Cesar Hill

5. T. Rex Like You Haven’t Seen Him: With Feathers by Jason Farago

6. common, cheap ingredients can break down some ‘forever chemicals’ by jude coleman, 1. what is science, 2. a noteworthy scientist, 3. why is it important to study science, 4. are robots a net positive for society, 5. types of sciences, 6. science’s role in warfare.

“Open-ended, unfettered science in its purest form has, over the centuries, been pursued in the interests of understanding nature in a fundamental way, and long may that continue. Scientific ideas and discoveries have often been very successfully exploited for commercial gain and societal improvements, and much of the science system today the world over is designed to push scientists in the direction of more relevance.”

For South Africa to prosper, Chetty encourages cooperation and innovation among scientists. He discusses several problems the country faces, including the politicization of research, a weak economy, and misuse of scientific discoveries. These challenges, he believes, can be overcome if the nation works as one and with the international community and if the education system is improved. 

“Technology can make people lazy. Many people are already dependent and embrace this technology. Like students playing computer games instead of going to school or study. Technology also brings us privacy issues. From cell phone signal interceptions to email hacking, people are now worried about their once private information becoming public knowledge and making profit out of video scandals.”

Gray discusses the adverse effects technology, a science product, has had on human life and society. These include pollution, the inability to communicate properly, and laziness. 

She also acknowledges that technology has made life easier for almost everyone but believes that technology, as it is used now, is detrimental; more responsible use of technology is ideal.

“We must give scientists the opportunity through funding and time to pursue curiosity-based, long-term, basic-science research. Work that does not have direct ramifications for industry or our economy is also worthy. There’s no telling what can come from supporting a curious mind trying to discover something new.”

Strickland, a Nobel Prize winner, explains that a great scientific discovery can only come with ample time for scientists to research, using her work as an example. She describes her work on chirped pulse amplification and its possible applications, including removing brain tumors. Her Nobel-awarded work was done over a long time, and scientists must be afforded ample time and funding to make breakthroughs like hers. 

4.  ​​ The fact of cloning by Cesar Hill

“Any research into human cloning would eventually need to be tested on humans. Cloning might be used to create a “perfect human”. Cloning might have a detrimental effect family relationship. However the debate over cloning has more pros out weighting the cons, giving us a over site of the many advantages cloning has and the effects of it as well. Cloning has many ups and downs nevertheless there are many different ways in which it can be used to adapt and analyse new ways of medicine.”

Hill details both the pros and cons of cloning. It can be used for medical purposes and help us understand genetics more, perhaps even allowing us to prevent genetic diseases in children. However, it is expensive, and many oppose it on religious grounds. Regardless, Hill believes that the process has more advantages than disadvantages and is a net good. 

“For the kids who will throng this new exhibition, and who will adore this show’s colorful animations and fossilized dino poop, T. rex may still appear to be a thrilling monster. But staring in the eyes of the feather-flecked annihilators here, adults may have a more uncanny feeling of identification with the beasts at the pinnacle of the food chain. You can be a killer of unprecedented savagery, but the climate always takes the coup de grâce.”

In his essay, Farago reviews an exhibition on the Tyrannosaurus Rex involving an important scientific discovery: it was a feathered dinosaur. He details the different displays in the exhibition, including models of other dinosaurs that helped scientists realize that the T-Rex had feathers. 

“Understanding this mechanism is just one step in undoing forever chemicals, Dichtel’s team said. And more research is needed: There are other classes of PFAS that require their own solutions. This process wouldn’t work to tackle PFAS out in the environment, because it requires a concentrated amount of the chemicals. But it could one day be used in wastewater treatment plants, where the pollutants could be filtered out of the water, concentrated and then broken down.”

Coleman explains a discovery by which scientists were able to break down a perfluoroalkyl and polyfluoroalkyl substance, a “forever chemical” dangerous to the environment. He explains how they could break the chemical bond and turn the “forever chemical” into something harmless. This is important because pollution can be reduced significantly, particularly in the water. 

Writing Prompts on Essays about Science

“Science” is quite a broad term and encompasses many concepts and definitions. Define science, explain what it involves and how we can use it, and give examples of how it is present in the world. If you want, you can also briefly discuss what science means to you personally. 

Many individuals have made remarkable scientific discoveries, contributing to the wealth of knowledge we have acquired through science. For your essay, choose one scientist you feel has made a noteworthy contribution to their field. Then, give a brief background on the scientists and explain the discovery or invention that makes them essential. 

Consider what it means to study science: how is it relevant now? What lessons can we learn from science? Then, examine the presence of science in today’s world and write about the importance of science in our day-to-day lives- be sure to give examples to support your points. Finally, in your essay, be sure to keep in mind the times we are living in today.

When we think of science, robots are often one of the first things that come to mind. However, there is much to discuss regarding safety, especially artificial intelligence. Discuss the pros and cons of robots and AI, then conclude whether or not the benefits outweigh the disadvantages. Finally, provide adequate evidence to reinforce your argument and explain it in detail. 

From biology to chemistry to physics, science has many branches, each dealing with different aspects of the world and universe. Choose one branch of science and then explain what it is, define basic concepts under this science, and give examples of how it is applied: Are any inventions requiring it? How about something we know today thanks to scientific discovery? Answer these questions in your own words for a compelling essay.

Undoubtedly, technology developed using science has had devastating effects, from nuclear weapons to self-flying fighter jets to deadly new guns and tanks. Examine scientific developments’ role in the war: Do they make it more brutal? Or do they reduce the casualties? Make sure to conduct ample research before writing your essay; this topic is debatable.

What Is Science?

Anyone can think like a scientist.

Science is . . .

Observing the world.

Watching and listening

Observing and recording.

Science is curiosity in thoughtful action about the world and how it behaves.

Anyone can have an idea about how nature works. Some people think their idea is correct because "it seems right" or "it makes sense." But for a scientist (who could be you!), this is not enough. A scientist will test the idea in the real world. An idea that predicts how the world works is called a hypothesis .

Hmmm. Is my hypothesis correct?

If an idea, or hypothesis, correctly predicts how something will behave, we call it a theory . If an idea explains all the facts, or evidence, that we have found, we also call it a theory .

"Scientific method" usually means a series of steps that scientists follow to discover how nature works.

These steps will work fine for a school science fair project. But this is not usually the way science actually happens!

From observation to theory

Sometimes the observations come before the idea or theory.

This drawing is similar to the one made by Nicolaus Copernicus (published in 1543) and shows the Sun at the center of the solar system.

For thousands of years, people observed certain "stars" wander around the night sky in looping patterns. Finally, in 1514 Nicolaus Copernicus came up with the idea of "Heliocentrism" (meaning Sun centered). He thought the Sun was the center of the Universe, with Earth being one of many spheres orbiting the Sun. That idea explained the wandering patterns of the planets. It also predicted where they would "wander" next. This idea became a theory. Of course, we later improved that theory. After all, the Sun is not the center of the whole universe, but only our own solar system.

Sometimes science happens mostly inside a scientist's head.

Albert Einstein and his theories were like that. It took a long time before scientists were able to test them and show that they were correct.

Science is not just a tidy package of knowledge.

Science is not just a step-by-step approach to discovery.

Science is more like a mystery inviting anyone who is interested to become a detective and join in the fun.

A sample experiment:

Do maple trees turn red in the fall because the days are growing shorter or because the weather is getting colder?

To find out . . .

First test the shorter days idea. Change the amount of time each day that the tree gets light. Keep everything else around the tree the same. Then, see if the tree changes color.

In this experiment, the amount of light the indoor tree gets is the variable and temperature and amount of water are the controls .

Put a potted maple tree (maple trees do turn red and lose their leaves in the fall) in a shed with artificial sunlight (and no windows). Give the tree less light each day—in this case, two minutes and a few seconds less, just as if it were outside during the fall. Keep the temperature constant and give the tree the same amount of water each week.

What if the leaves turn red on the indoor tree just as they do on the outdoor trees?

What would that mean? It would mean that it must be the shorter periods of light that is making the leaves turn red.

But what if the leaves do not turn red on the indoor tree?

In that case, the amount of light is not the cause, or at least not the main cause, of the trees outside turning red. Our scientist might then design another experiment with temperature as the variable, holding light and water constant, as the controls.

Science is the study of logic. It explains why the world is round, why stars twinkle, why light travels faster than sound, why hawks soar higher than crows, why sunflowers face the sun and other phenomena. Science answers every question logically rather than offering mystical interpretations. Students are very interested in science as a topic. This subject is indeed crucial for those hoping to pursue careers in science and related professions.

People who are knowledgeable in science are more self-assured and aware of their environment. Knowing the cause and origin of natural events, a person knowledgeable in science will not be afraid of them.

However, science also has a big impact on a country’s technological advancement and illiteracy.

We have included a brief and lengthy English essay on science below for your knowledge and convenience. The writings have been thoughtfully crafted to impart to you the relevance and meaning of science. You will understand what science is, why it matters in daily life, and how it advances national progress after reading the writings. These science essays can be used for essay writing, debate, and other related activities at your institution or school.

Science entails a thorough examination of the behavior of the physical and natural world. Research, experimentation, and observation are used in the study.

The scientific disciplines are diverse. The social sciences, formal sciences, and natural sciences are some of them. Subcategories and sub-sub-categories have been created from these basic categories. The natural sciences include physics, chemistry, biology, earth science, and astronomy; the social sciences include history, geography, economics, political science, sociology, psychology, social studies, and anthropology; and the formal sciences include computer science, logic, statistics, decision theory, and mathematics.

The world has positively transformed because of science. Throughout history, science has produced several inventions that have improved human convenience. We cannot fathom our lives without several of these inventions since they have become essential parts of them.

Global scientists persist in their experiments and occasionally produce more advanced innovations, some of which spark global revolutions. Even if science is helpful, some people have abused knowledge, usually those in positions of authority, to drive an arms race and destroy the environment.

There is no common ground between the ideologies of science and religion. These seeming opposite viewpoints have historically led to a number of confrontations and still do.

Science is a way to learn about, comprehend, examine, and experiment with the physical and natural features of the world in order to apply it to the development of newer technologies that improve human convenience. In science, observation and experimentation are broad and not restricted to a specific concept or area of study.

Applications of Science

Science has given us almost everything we use on a daily basis. Everything, from laptops to washing machines, microwaves to cell phones, and refrigerators to cars, is the result of scientific experimentation. Here are some ways that science affects our daily lives:

Not only are refrigerators, grills, and microwaves examples of scientific inventions, but gas stoves, which are frequently used for food preparation, are as well.

Medical Interventions

Scientific advancements have made it feasible to treat a number of illnesses and conditions. Thus, science encourages healthy living and has helped people live longer.

Interaction

These days, mobile phones and internet connections are necessities in our life and were all made possible by scientific advancements. These innovations have lowered barriers to communication and widened global connections.

E nergy Source

The creation and application of numerous energy forms have been facilitated by the discovery of atomic energy. One of its greatest innovations is electricity, and everyone is aware of the effects it has on daily life.

Variety in Cuisine

There has also been an increase in food diversity. These days, a wide variety of fruits and vegetables are available year-round. It’s not necessary to wait for a given season to enjoy a certain meal. This modification is the result of scientific experimentation.

So, science is a part of our daily existence. Without scientific advancements, our lives would have been considerably more challenging and varied. Nonetheless, we cannot ignore the fact that a great deal of scientific innovation has contributed to environmental deterioration and a host of health issues for humankind.

There are essentially three main disciplines of science. The Natural Sciences, Social Sciences, and Formal Sciences are some of them. To examine different aspects, these branches are further divided into subcategories. This is a thorough examination of these groups and their subgroups.

Scientific Subdisciplines

Natural Science

This is the study of natural phenomena, as the name implies. It investigates how the cosmos and the world function. Physical science and life science are subcategories of natural science.

a) Science of Physics

The subcategories of physical science comprise the following:

• Physics is the study of matter’s and energy’s properties.
• Chemistry is the study of the materials that make up matter.
• The study of space and celestial bodies is called astronomy.
• Ecology is the study of how living things interact with their natural environments and with one another.
• Geology: It studies the composition and physical makeup of Earth.
• Earth science is the study of the atmosphere and the physical makeup of the planet.
• The study of the physical and biological components and phenomena of the ocean is known as oceanography.
• Meteorology: It studies the atmospheric processes.

The subcategories of life science include the following:

• The study of living things is called biology.
• The study of plants is known as botany.
• The study of animals is known as zoology.

c) Social Science

This includes examining social patterns and behavioral patterns in people. It is broken down into more than one subcategory. Among them are:

• History: The examination of past occurrences
• Political science is the study of political processes and governmental structures.
• Geographic: Study of the atmospheric and physical characteristics of Earth.
• Human society is studied in social studies.
• Sociology: The study of how societies form and operate.

Academic Sciences

It is the area of study that examines formal systems like logic and mathematics. It encompasses the subsequent subcategories:

• Numbers are studied in mathematics.
• Reasoning is the subject of logic.
• Statistics: It is the study of numerical data analysis.
• Mathematical analysis of decision-making in relation to profit and loss is known as decision theory.
• The study of abstract organization is known as systems theory.
• Computer science is the study of engineering and experimentation as a foundation for computer design and use.

Scientists from several fields have been doing in-depth research and testing numerous facets of the subject matter in order to generate novel ideas, innovations, and breakthroughs. Although these discoveries and technologies have made life easier for us, they have also permanently harmed both the environment and living things.

Introduction

Science is the study of various physical and natural phenomena’ structures and behaviors. Before drawing any conclusions, scientists investigate these factors, make extensive observations, and conduct experiments. In the past, science has produced a number of inventions and discoveries that have been beneficial to humanity.

I deas in Religion and Science

In science, new ideas and technologies are developed through a methodical and rational process; in religion, however, beliefs and faith are the only factors considered. In science, conclusions are reached by careful observation, analysis, and experimentation; in religion, however, conclusions are rarely reached through reason. As a result, they have very different perspectives on things.

Science and Religion at Odds

Because science and religion hold different opinions on many issues, they are frequently perceived as being at odds. Unfortunately, these disputes occasionally cause social unrest and innocent people to suffer. These are a few of the most significant disputes that have happened.

The World’s Creation

The world was formed in six days, according to many conservative Christians, sometime between 4004 and 8000 BCE. However, cosmologists assert that the Earth originated about 4.5 billion years ago and that the cosmos may be as old as 13.7 billion years.

The Earth as the Universe’s Center

Among the most well-known clashes is this one. Earth was considered to be the center of the universe by the Roman Catholic Church. They say that it is surrounded by the Sun, Moon, stars, and other planets. Famous Italian mathematician and astronomer Galileo Galilei’s discovery of the heliocentric system—in which the Sun is at the center of the solar system and the Earth and other planets orbit it—led to the conflict.

Eclipses of the Sun and Moon

Iraq was the scene of one of the first wars. The locals were informed by the priests that the moon eclipse was caused by the gods’ restlessness. These were seen as foreboding and intended to overthrow the kings. When the local astronomers proposed a scientific explanation for the eclipse, a disagreement arose.

There are still many myths and superstitions concerning solar and lunar eclipses around the world, despite astronomers providing a compelling and rational explanation for their occurrence.

In addition to these, there are a number of other fields in which religious supporters and scientists hold divergent opinions. While scientists, astronomers, and biologists have evidence to support their claims, the majority of people adhere closely to religious beliefs.

Not only do religious activists frequently oppose scientific methods and ideas, but many other facets of society have also taken issue with science since its discoveries are leading to a host of social, political, environmental, and health problems. Nuclear weapons are one example of a scientific invention that threatens humanity. In addition, the processes involved in preparation and the utilization of the majority of scientifically created equipment contribute to pollution, making life more difficult for all.

In the previous few decades, a number of scientific advancements and discoveries have greatly eased people’s lives. The previous ten years were not an anomaly. A good number of important scientific discoveries were acknowledged. The top ten most amazing recent scientific inventions are shown below.

New Developments and Findings in Science

Amputee Gains Control of Biomechanical Hand via Mental After a tragic accident took away his forearm, Pierpaolo Petruzziello, an Italian, used his mind to control a biomechanical hand attached to his arm. The hand used wires and electrodes to connect to the nerves in his arm. He became the first to become skilled at doing motions like gripping objects, wriggling his fingers, and moving.

The Global Positioning System

How to Write a Short Essay

Last Updated: January 17, 2024 Fact Checked

This article was co-authored by Christopher Taylor, PhD . Christopher Taylor is an Adjunct Assistant Professor of English at Austin Community College in Texas. He received his PhD in English Literature and Medieval Studies from the University of Texas at Austin in 2014. There are 12 references cited in this article, which can be found at the bottom of the page. This article has been fact-checked, ensuring the accuracy of any cited facts and confirming the authority of its sources. This article has been viewed 113,763 times.

Essay writing is a common assignment in high school or college courses, especially within the humanities. You’ll also be asked to write essays for college admissions and scholarships. In a short essay (250-500 words), you will need to provide an introduction with a thesis, a body, and a conclusion, as you would with a longer essay. Depending on the essay requirements, you may also need to do academic or online research to find sources to back up your claims.

Picking a Topic and Gathering Research

• If you have any questions about the topic, ask your instructor. If your essay doesn't respond to the prompt, you likely won't receive full credit.

• If you're writing an essay for an in-class test or for an application, tailor the essay to the given prompt and topic. Quickly brainstorm a few ideas; for example, think of positive things you can say about yourself for a college-entrance essay.
• For example, the topic “depression in American literature” is far too broad. Narrow down your topic to something like “Willie Loman’s depression in Death of a Salesman .”
• Or, you could write about a narrow topic like “the increase in the USA’s national debt in the 1950s” rather than a broad topic like “the American economy in the 20th century.”

• Depending on the field in which you’re writing the essay—e.g., hard sciences, sociology, humanities, etc.—your instructor will direct you towards appropriate databases. For example, if you’re writing a high-school or college-level essay for your English class, visit online literary databases like JSTOR, LION, and the MLA Bibliography.
• If you're writing the essay for a college or graduate-school application, it's unlikely that you'll need to include any secondary sources.
• If you're writing a timed or in-class essay, you may not be able to find research articles. But, still do draw information from texts and sources you've studied both in and out of class, and build from points made in any provided reading passages.

• If you’re writing about current events or journalism topics, read articles from well-known news sites like CNN or the BBC.
• Avoid citing unreliable websites like blogs or any sites that have a clear bias about the topic they’re reporting on.

Composing the Essay

• If you write the essay without outlining, the essay will be poorly organized.

• This thesis statement is far too weak: “ Death of a Salesman shows the difficulty of living in America after WWII.”
• Instead, hone your thesis to something like: “Arthur Miller uses Death of a Salesman to show that the American Dream is materialist and impractical.”

• So, avoid beginning the paragraph by writing something like, “Since the beginning of time, all people have been consumed with the desire for their father’s approval.”
• Instead, write something like, “In the play Death of a Salesman , Willie Loman’s sons compete for their father’s approval through various masculine displays."
• Then, you can say, "To examine this topic, I will perform a close reading of several key passages of the play and present analyses by noted Arthur Miller scholars."

• In a short essay, the conclusion should do nothing more than briefly restate your main claim and remind readers of the evidence you provided.

• So, take the example about Death of a Salesman . The first body paragraph could discuss the ways in which Willie’s sons try to impress him.
• The second body paragraph could dive into Willie’s hopelessness and despair, and the third paragraph could discuss how Miller uses his characters to show the flaws in their understanding of the American Dream.

• Always cite your sources so you avoid charges of plagiarism. Check with your instructor (or the essay prompt) and find out what citation style you should use.
• For example, if you’re summarizing the inflation of the American dollar during the 1930s, provide 2 or 3 years and inflation-rate percentages. Don’t provide a full-paragraph summary of the economic decline.
• If you're writing an in-class essay and don't have time to perform any research, you don't need to incorporate outside sources. But, it will impress your teacher if you quote from a reading passage or bring up pertinent knowledge you may have gained during the class.

• If no one agrees to read the essay, read over your own first draft and look for errors or spots where you could clarify your meaning. Reading the essay out loud often helps, as you’ll be able to hear sentences that aren’t quite coherent.
• This step does not apply to essays written during a timed or in-class exam, as you won't be able to ask peers to read your work.

• It’s always a mistake to submit an unrevised first draft, whether for a grade, for admissions, or for a scholarship essay.
• However, if you're writing an essay for a timed exam, it's okay if you don't have enough time to combine multiple drafts before the time runs out.

Condensing Your Essay

• So, if you’re writing about Death of a Salesman , an article about symbolism in Arthur Miller’s plays would be useful. But, an article about the average cost of Midwestern hotels in the 1940s would be irrelevant.
• If you’re writing a scholarship essay, double-check the instructions to clarify what types of sources you’re allowed to use.

• A common cliche you might find in an essay is a statement like, "I'm the hardest working student at my school."
• For example, this sentence is too verbose: “I have been a relentlessly stellar student throughout my entire high school career since I am a seriously dedicated reader and thoroughly apply myself to every assignment I receive in class.”
• Shortened, it could read: “I was a stellar student throughout my high school career since I was a dedicated reader and applied myself to every assignment I received.”

• Avoid writing something like, “Willie Loman can be seen as having achieved little through his life because he is not respected by his sons and is not valued by his co-workers.”
• Instead, write, “Arthur Miller shows readers that Willie’s life accomplishments have amounted to little. Willie’s sons do not look up to him, and his co-workers treat him without respect.”

• For example, if you’re trying to prove that WWII pulled the USA out of the Great Depression, focus strictly on an economic argument.
• Avoid bringing in other, less convincing topics. For example, don’t dedicate a paragraph to discussing how much it cost the USA to build fighter jets in 1944.

Short Essay on My Favourite Subject Science [100, 200, 400 Words] With PDF

In this lesson, you are going to learn how you can write short essays on your favourite subject science. Here will be three sets of essays written on the same topic, covering different word limits.

Table of Contents

Short essay on my favourite subject science in 100 words, short essay on my favourite subject science in 200 words, short essay on my favourite subject science in 400 words.

In our school days, as a student, we have to study lots of subjects altogether. It feels hectic to control so many at a time. Yet among all of these, some subjects really occupy our hearts. It is our favourite of all and soon it becomes the target of our higher studies.

For me, however, science is my favourite subject. I have forever admired it as my best. I love scientific experiments and how science is helping us daily to better ourselves. If science would not have been there, then it would have been impossible to develop in any way. Science is one of the bases for human development and hence one of my favourite subjects.

All of us have one subject in our school that we admire a lot. It is our favourite and something that we want to read in the future. For me, that subject is science. In school, some subjects were good, while others felt too tough to study.

I really did not like to read everything. But among all, science was the only one I loved. I still enjoy knowing about it. Science means experiments. The book contains pictures of so many experiments that I enjoy reading. The laboratory contains so many materials for that purpose. I love science as it does not allow superstitions. It depends on reason and facts. I enjoy how regular research for our development is taking place due to the help of science.

Today we have realized the importance of science. Even in a pandemic, we have received vaccines and medicines in little time. Medical treatments are well developed now, and all diseases can be cured easily. Science is one of the reasons for the development of India. Several vehicles for communication are present today.

The Universe is no longer unknown to us. We realize how our nature is constantly helping us. The industries are enabling us a better future. In fact, robots are now used for serving human needs. This enormous success of humans is actually the blessing of scientific studies. So I dream to become a researcher and study this beautiful field.

Everyone in our school has written an essay on science as a curse or a boon. It is a debate if science actually helps us or destroys us further. But beyond everything, I love to study science as it is my favourite subject. In school, we read several subjects.

We love to study some, while others become quite boring. For me, science was that one subject that I enjoyed a lot. In fact, till today I love to study scientific information and the development that is daily enriching our lives. The best thing about it is that it does not allow any superstition. Science is based upon reason and analysis of facts. So it is impossible to have any ill knowledge where there is the cultivation of science. 

I started loving science when our teacher showed us some fun experiments. I soon realized science is not some word in the books, but a fact-based subject. The books were pretty, they had lots of pictures. But I did not feel excited about knowing it till I understood the truth behind this subject. Science is observing and analyzing something properly.

The scientific laws are examples of such deeper studies made by several scientists. Only logic and reason create science. This idea caught my mind. I started taking interest in this subject and soon it became my best subject. The laboratory became my favourite place, where I did all the experiments I read in the textbook. Even today I love to read science fiction, journals, and the interviews of many scientists and increase my knowledge about this topic.

Another reason for making science my favourite subject is that we develop because of science. Science saves us from the severity of the calamities. Human beings are ever curious to know about the world and the Universe. Science has enabled them in this process. Everything is scientific. Medical procedures are rapidly changing for the benefit of mankind.

New medicines, vaccines are being invented to fight the most deadly virus. Industries are ever-growing; several forms of communication are available today; equipment like phones, TV, washing machine, inductions, etc. are our daily need; alternative ways to collect rain, dispose of garbage, create electricity are available. Robots are now human help. All of these are blessings of science. Science has shown us an efficient lifestyle. Even the farthest planet is now known to us. Science has made the impossible come true. So I will forever love to study and research on this subject.

In today’s lesson, I have written the essays in a very simple language for a better understanding of all kinds of students. If you still have any doubts regarding this lesson, kindly let me know through the comment section below. To read more about such seasons, keep browsing our website. 

Thank you.

Avoid common mistakes on your manuscript.

David Pimentel (1925–2019) was a pioneer in the field of agroecology and more in general of sustainability science (for a biography see https://en.wikipedia.org/wiki/David_Pimentel_(scientist )). His work stands out for its breadth and timeliness. Professor of entomology and agroecology at the College of Agriculture and Life Sciences of Cornell University (Ithaca, New York, USA), David Pimentel published more than 500 scientific articles and book chapters, 3 monographs, and 34 edited books spanning a broad range of environmental issues related to socio-economic development. In 1999, together with Luc Hens and Bhaskar Nath, he founded the journal Environment, Development and Sustainability .

His work was characterized by transdisciplinarity, and he served as an inspiration for many researchers in the field of sustainability science to broaden their view and embrace a more holistic and critical vision of the functioning of social-ecological systems and human development.

Common sense combined with relatively simple quantitative reality checks, rather than complicated models, was the approach undertaken by David Pimentel to investigate the consistency of the narratives suggested in sustainability science. In this sense, he may be considered an early exponent of ‘quantitative storytelling’.

He also adopted a novel teaching approach. Moving away from the dominant reductionistic doctrine, he pushed his students to embrace a system approach, training them in teamwork and addressing real case studies. Often these group exercises resulted in publications in important scientific journals.

Most of Pimentel’s research addressed wicked environmental problems related to the sustainability of human development, such as biological control, pesticide use, organic and alternative farming practices, soil erosion, loss of biodiversity, genetic engineering, biofuels and biomass energy, fossil energy dependence of the food system, and the relation between population growth and limited natural resources. His capacity to integrate a vast body of knowledge across different scientific fields and to address problems from different perspectives, his free spirit independent from politically correct ideologies and economic interests, and his great intuition, allowed him to bring this often “uncomfortable knowledge” to the attention of the scientific community, policy makers, and lay people alike, in a clear and unequivocal way.

For example, he was among the first scholars to alert to: (i) the dependence of our food system on fossil energy, making us aware that “we are eating oil”; (ii) the significant cost of producing meat, flagging that the USA could feed 800 million people with the grain consumed by livestock; (iii) the unviability and unsustainability of biofuels as alternative energy carriers to fuel modern society; (iv) the risk of increased herbicide use in genetically modified herbicide resistant crops. All this uncomfortable news challenged the sustainability myths of his time (some of which, unfortunately, persist to the present day).

The role of ‘uncomfortable knowledge’ as Steve Rayner defined it (Rayner, 2012, Economy and Society, pp. 107–125), played a major role in sustainability analysis. As Rayner puts it: “ to make sense of the complexity of the world so that they can act, individuals and institutions need to develop simplified, self-consistent versions of that world … knowledge which is in tension or outright contradiction with those versions must be expunged. This is uncomfortable knowledge which is excluded from policy debates, especially when dealing with ‘wicked problems’ ”.

In line with David Pimentel’s attention to wicked environmental problems, this special issue presents a number of contributions that address sustainability discussions in the field of agro-food systems.

In this topical issue, the paper by Crews and Polk illustrates the role for soil conservation and carbon accumulation of developing perennial grain agroecosystems, in an attempt to mimic prairies native ecosystems. Developing perennials, allowing a large-scale production, may represent a turning point toward a truly more sustainable agriculture.

Domínguez et al. explore in depth the advantages of alternative farming systems by expanding the set of criteria for evaluating the performance of food production and considering the nexus between the different factors of production.

Kleinman and Harmel look into the trade-offs of global nutrient redistribution, the analysis of which is essential to identify “challenges of” and “opportunities for” a global transformation to a more sustainable resource management.

Abdul Aziz et al. present an integrated assessment of sustainable foraging knowledge and practices, using examples from different geographic regions, and show that these have an important role to play in the future of sustainable agriculture.

Cadillo-Benalcazar et al. present a model to study the complexity of the society–agriculture–forest system and illustrate it for the case study of Huayopata in Cuzco (Peru), where public policies for tea production interact with the complexity of the society–agriculture–forest system.

Orozco-Meléndez and Paneque-Gàlvez challenge the predominance of the disciplinary vision that shapes the existing “corporate food regime”. Using literature review and a conceptual approach they show the need for a transition to another method of governance based on co-design and co-production of uncomfortable, transdisciplinary, and actionable knowledge.

Zanardo et al. address the controversial “horn manure” (Preparation 500) used in biodynamic agriculture. They studied the changes during the manure maturation of the fungal and bacterial communities inside the horns of cows. The analysis suggests that significant changes take place during the process. This work proves that notwithstanding the demonization of biodynamic agriculture as an esoteric quackery, still there are aspects of biodynamic agriculture that can be scientifically investigated.

Giampietro illustrates the “magic” of the unique procedure developed by David Pimentel to quantify systems of agricultural production in terms of profiles of inputs and outputs. This procedure establishes bridges among data referring to different dimensions (social, economic, technical, ecological) and to different scales, when utilizing the patterns of profiles in their scaled form—per hectare—and in the form of technical coefficients—unitary processes.

Ponti and Gutierrez address the important issue of invasive species and their environmental and economic impacts, and argue that it is essential to be able to monitor weather-driven dynamics and potential geographic distribution and abundance. To this purpose, the authors present a new approach—Physiologically Based, Demographic Models (PBDMs)—that avoids the limitations of existing methods.

Alfonso-Bécares et al. use the concept of societal and ecosystem metabolic analysis to study policies of forest conservation. Employing a quantitative characterization based on profiles of inputs and outputs, the authors establish a link between: (i) changes in the heterogeneity of livelihoods found in a given farming system, and (ii) changes in the patterns of land uses. This link is then used to run “what if” scenarios associated with different policy options.

Díaz-Siefer et al. study the factors that prevent a transition to greener agriculture in Chiapas, Mexico, and in particular the type of conditioning that the socio-economic context poses. They identify three relevant actors: (i) the policies and regulation developed by the governments; (ii) the choices of the consumers; (iii) the quantities of subsidies that can be used made available by financial agents and suggest possible adjustments to get out of the impasse.

Tips to answer multiple-choice, short-answer, and essay-type questions in exams

E xams are a stressful affair and they require smart strategies and techniques to excel. While in-depth learning is crucial, different types of questions demand specific strategies and approaches for solving.

Exams may appear in several formats including multiple choice questions, short answers and essays, each requiring different techniques of answering.

Below is a comprehensive guide to solving exams with different types of question patterns:

TIPS TO ANSWER MULTIPLE CHOICE QUESTIONS

• The first and foremost thing to do is to read the questions properly. Often, students miss out on important details due to a lack of focus. Paying attention to each and every piece of information and reading with attention is crucial.
• After reading the question, try to predict the answer without referring to the given options. This increases your chances of selecting the correct answer through educated guessing.
• Using the process of elimination can do wonders. In this method, you eliminate the options you believe are incorrect. This narrows down your choices and aids in identifying the correct response.
• Paying attention to words such as 'always,' 'never,' 'sometimes,' 'most,' 'only,' 'many,' 'but,' and 'often' can help us better understand the sentence. These words tend to alter the meaning of the sentence and hence should be paid attention to and read properly.
•  Understanding concepts thoroughly enables you to grasp the context of questions accurately and answer them correctly.

TIPS TO ANSWER SHORT QUESTIONS

• Read the question properly and comprehend it well. Understand whether you need to give a definition, provide examples, write a brief summary or offer comparisons.
• Write the answer to the point, avoiding unnecessary explanations and using keywords. This increases your chances of scoring higher.
• Use simple language and avoid complex terms, as they can confuse the examiner. The simpler your answer, the higher your score.
• Write your answers in a logical and organised manner. Structure your answers with separate paragraphs, bullet points, flowcharts, tables, etc., as this makes it easier for the examiner to read and understand your answer.
• During the preparatory phase, use colourful pens, flashcards, charts, and drawings to learn concepts well. This method helps in recollecting the answers during exams.
• Indulge in self-testing methods by practicing sample question papers, demo tests, and solving previous year question papers to understand the probable questions and the exam pattern.
• Having a time management strategy in place is important. Allocate time for different types of questions and try to solve them within the given time frame.

TIPS TO WRITE ESSAYS

• Understand the topic well and follow the instructions.
• Brainstorm ideas on the topic and plan the points you intend to include.
• Begin with an informative yet concise introduction, followed by a detailed body and a conclusion that summarizes your essay.
• Ensure the essay is well-structured and divided into a minimum of 3-4 paragraphs.
• Use quotations and examples to support the information you have written.
• Adhere to the specified time and word limits.
• Ensure your essay is written in simple and clear language.
• Always remember to proofread the essay to eliminate grammatical and spelling errors.
• Make reading a regular practice to enhance language proficiency and facilitate a smoother flow of thoughts.

By implementing such strategic approaches, you can efficiently answer your questions. It is important to study diligently and practice with sample papers.

During the exam, take the time to read the question paper properly during the allocated reading time and manage your time effectively.

Facility for Rare Isotope Beams

At michigan state university, international research team uses wavefunction matching to solve quantum many-body problems, new approach makes calculations with realistic interactions possible.

FRIB researchers are part of an international research team solving challenging computational problems in quantum physics using a new method called wavefunction matching. The new approach has applications to fields such as nuclear physics, where it is enabling theoretical calculations of atomic nuclei that were previously not possible. The details are published in Nature (“Wavefunction matching for solving quantum many-body problems”) .

Ab initio methods and their computational challenges

An ab initio method describes a complex system by starting from a description of its elementary components and their interactions. For the case of nuclear physics, the elementary components are protons and neutrons. Some key questions that ab initio calculations can help address are the binding energies and properties of atomic nuclei not yet observed and linking nuclear structure to the underlying interactions among protons and neutrons.

Yet, some ab initio methods struggle to produce reliable calculations for systems with complex interactions. One such method is quantum Monte Carlo simulations. In quantum Monte Carlo simulations, quantities are computed using random or stochastic processes. While quantum Monte Carlo simulations can be efficient and powerful, they have a significant weakness: the sign problem. The sign problem develops when positive and negative weight contributions cancel each other out. This cancellation results in inaccurate final predictions. It is often the case that quantum Monte Carlo simulations can be performed for an approximate or simplified interaction, but the corresponding simulations for realistic interactions produce severe sign problems and are therefore not possible.

Using ‘plastic surgery’ to make calculations possible

The new wavefunction-matching approach is designed to solve such computational problems. The research team—from Gaziantep Islam Science and Technology University in Turkey; University of Bonn, Ruhr University Bochum, and Forschungszentrum Jülich in Germany; Institute for Basic Science in South Korea; South China Normal University, Sun Yat-Sen University, and Graduate School of China Academy of Engineering Physics in China; Tbilisi State University in Georgia; CEA Paris-Saclay and Université Paris-Saclay in France; and Mississippi State University and the Facility for Rare Isotope Beams (FRIB) at Michigan State University (MSU)—includes  Dean Lee , professor of physics at FRIB and in MSU’s Department of Physics and Astronomy and head of the Theoretical Nuclear Science department at FRIB, and  Yuan-Zhuo Ma , postdoctoral research associate at FRIB.

“We are often faced with the situation that we can perform calculations using a simple approximate interaction, but realistic high-fidelity interactions cause severe computational problems,” said Lee. “Wavefunction matching solves this problem by doing plastic surgery. It removes the short-distance part of the high-fidelity interaction, and replaces it with the short-distance part of an easily computable interaction.”

This transformation is done in a way that preserves all of the important properties of the original realistic interaction. Since the new wavefunctions look similar to that of the easily computable interaction, researchers can now perform calculations using the easily computable interaction and apply a standard procedure for handling small corrections called perturbation theory.  A team effort

The research team applied this new method to lattice quantum Monte Carlo simulations for light nuclei, medium-mass nuclei, neutron matter, and nuclear matter. Using precise ab initio calculations, the results closely matched real-world data on nuclear properties such as size, structure, and binding energies. Calculations that were once impossible due to the sign problem can now be performed using wavefunction matching.

“It is a fantastic project and an excellent opportunity to work with the brightest nuclear scientist s in FRIB and around the globe,” said Ma. “As a theorist , I'm also very excited about programming and conducting research on the world's most powerful exascale supercomputers, such as Frontier , which allows us to implement wavefunction matching to explore the mysteries of nuclear physics.”

While the research team focused solely on quantum Monte Carlo simulations, wavefunction matching should be useful for many different ab initio approaches, including both classical and  quantum computing calculations. The researchers at FRIB worked with collaborators at institutions in China, France, Germany, South Korea, Turkey, and United States.

“The work is the culmination of effort over many years to handle the computational problems associated with realistic high-fidelity nuclear interactions,” said Lee. “It is very satisfying to see that the computational problems are cleanly resolved with this new approach. We are grateful to all of the collaboration members who contributed to this project, in particular, the lead author, Serdar Elhatisari.”
