What is Physics?

Physics is the masterpiece of human culture. it is a combination of philosophy and mathsmatics. philosophy provide a willing and way to find rules before objects by watching and concluding. and mathematics provides tools. so physics is just one thing which allows us to write the world on paper, understand them by number.

Description by Kaiyu M. (physics major at National University of Singapore (NUS))

Physics, a branch of science, is the study of forces and their impacts on the environment. Modern physics connects ideas together about the laws of symmetry and conservation (energy, momentum, charge, and parity)

Description by Saurabh S. (Computer Science major at VIT University)

Physics is often described as the study of matter and energy. It is concerned with how matter and energy relate to each other, and how they affect each other over time and through space.

"You take the blue pill. The story ends. You wake up in your bed and believe whatever you want to believe. You take the read pill. You stay in Wonderland and I show you just how deep the rabbit hole goes. Remember. All I am offering you is the truth, nothing more."
-Morpheus, The Matrix

Description by Kenneth A. (Studio Art major at University of Central Florida)

Physics can cover a wide range of topics. What really appeals to me in physics is the possibility of discovering new ways to think about a task, explain a situation, or execute some sort of process. Physics will take the math that you know and put it into perspective using the world around you. This could range from the largest star in the universe, to the smallest atom In the ocean, to making and testing designs for an invisibility cloak. With physics, the boundaries are limitless.

Description by Vimal D. (Master of Science Program in Information Technology major at University of the West of England)

Physics provides a way to mathematically formulate the rules that nature follows . Thus being able to manipulate mathematics , we can delve into the mysteries of the world and find deeper truths about it . Mathematically describing nature also provides a great way to make precise predictions about it.

Description by Gregory G. (Mathematical Physics major at The University of Edinburgh)

Description by John E. (Physics major at UC Berkeley)

The study of matter, energy and the interaction between the two.

Description by Arup D. (Systems Engineering major at University of Arkansas at Little Rock)

Physics is the scientific study of matter and energy and how they interact with each other.
This energy can take the form of motion, light, electricity, radiation, gravity . . . just about anything, honestly. Physics deals with matter on scales ranging from sub-atomic particles (i.e. the particles that make up the atom and the particles that make up those particles) to stars and even entire galaxies.

Description by Yanyue N. (Applied Mathematics/Statistics major at New York University)

Physics boils down to mathematically modeling FORCES, and how they are transmitted from one object to another, and with what specific affects.

Description by an InstaEDU tutor

Its a phenomena present in everything around us. The way we interact, the way any matter interacts with its surroundings, its properties i.e. why it behaves the way it does, the way the energy gets transferred around the universe; everything can be understood using some laws of physics. This study contains a set of rules or a framework which explains everything around in the universe.

Description by Abhishek B. (Electrical Engineering major at University of California Los Angeles)

Physics is the study of nature and its laws. There are a large number of objects and events taking place around us. We expect that all these different events in nature take place according to some basic laws and revealing these laws of nature from the observed events is Physics.
For example, the orbiting of moon around the Earth, falling of an apple from a tree and tides in a sea on a full moon can all be explained if we know the Newton's law of gravitation and Newton's laws of motion.

Description by Nouman A. (Marine Engineering Department major at Pakistan Marine Academy)

Physics is often considered the 'science of everything,' and I agree that it has the broadest reach of the sciences. Physics breaks down how things behave using math. While the talk of physics can quickly turn into a complex one, relativistic physics is easy to picture and comprehend, because it is what we see every single day, with the way how our car accelerates and slows, how the engine produces work, how friction and gravity produce forces that we feel. I also enjoy physics due to how closely it relates to chemistry, and many concepts can be explained from both a physical and chemical perspective.

Description by Trent H. (Education major at SUNY Plattsburgh)

Description by Thiru E. (22 major at OSMANIA UNIVERSITY, HYDERABAD)

Physics attempts to describe the substances that make up and influence the physical universe--mass, energy, momentum, and waves. It tells us both how and why things move, and attempts to establish physical models to predict the behavior of physical systems. Physics incorporates the full arsenal of modern mathematics heavily, so if you plan to take lots of physics, take as much mathematics as you possibly can!

Description by Joseph V. (Mathematics major at University of Michigan)

Physics is actually a logical explanation of natural phenomenon in form of a rule. The relation between matter and energy can be explained by physics.It can predict the behavior of matter within a system under different circumstances, by which we can implement this knowledge to explain and predict natural and celestial incidents.

Physics is the study study of physical phenomena of matter and nature also.

Description by Tayyab M. (chemistry major at govt post graduate college jhelum)

Physics, in the most general sense, is the study of the predictable nature of the universe. It is described using the language of mathematics. You will learn what makes up particles, how force affects velocity and acceleration, what an electromagnetic field is, what a "quantum" is, and how to describe the motion of bodies in a gravitational field, to name but small sample of physical ideas. You will find that these concepts describe the workings of your everyday life and experience.

Description by Tristan M. (Physics, Applied Mathematics major at University of California, Berkeley)

Physics, at its core, is the essence of science; it attempts to find a model that predicts the behavior of physical objects and phenomenon. Physics specifically deals with some of the more basic things, such as particles and energy, velocity and acceleration, movement and momentum. It tries to look at the basics of how things fundamentally interact with each other.

Description by an InstaEDU tutor

Physics is the study of physical phenomena and the relationships that exist between them.

Description by Cameron R. (Computer Science major at Sarah Lawrence College)

Physics allows to explain what is happening in the world around us. One of the main staples of physics is the set of Newton's three laws, which deal with forces and movement. Physics helps us determine and predict the motion of objects. For example, we can determine the speed of a car after a certain amount of time if we know it's acceleration. Physics explains how and why the planets orbit the sun. It is an extremely broad topic and also includes heat, magnetism, electricity, and waves.

Description by Timothy L. (Bioengineering major at Cornell University)

One thing I would say about physics : that discipline that once implemented ,the extraordinary surrounding , falls into trivial and logic one .physics helps you to understand the things around you ,so better have a little effort in understanding it . The subject itself represent a link between many scientific fields , in such a way that if you are good in physics ,you're a good engineer a good philosopher and a good researcher as well .

Description by Ahmed D. (Electrical engineering major at KAIST university )

Physics is the study of matter, forces, and energy and is the underlying science between every single moment of our lives. Not a single interaction between objects cannot be analyzed and described by physics. Physics is the basis behind many types of engineering concepts which engineers use to build the objects and vehicles and buildings we all use today.

Description by Rich S. (Finance & Industrial Engineering major at Lehigh University)

Physics is the study of the laws governing the world around you. How fast things move, the way fluids interact, how thermal energy transfers from one median to the next. Physics is the study of how and why the world works the way it does.

Description by Christopher H. (Physics major at University of Chicago)

The study of physics, at its most basic level, is the study of matter. Everything you can see and touch (and a lot of things you can't see and can't touch) is matter. Through centuries of observation, scientists have found patterns in the way that matter interacts with other matter, patterns that can be described using mathematic formulas. The study of physics involves the use of these formulas to make predictions about different scenarios in the physical world.

Description by Ben (Economics and Music major at Carleton College)

From particles tinier than atoms to the most gigantic galaxies, Physics is the study of the universe and how it works. It can be further broken up into two very broad categories:
1) matter (a.k.a. stuff) and what makes it all up
2) how matter interacts

Description by Jackson C. (Physics major at University of Texas at Dallas)

Physics is a mathematical approach to describing the behavior of what happens in the world around us. In applying mathematics, specifically calculus, to real world phenomena, we gain a deeper understanding of the world that we live in. It is not just as simple as memorizing equations, it is about understanding the world and how it behaves in different situations.

Description by Yatit T. (Environmental Engineering major at University of Florida)

Basically, it's how we can explain why nature is so regular and seems to obey certain laws. With the laws of Physics, we can predict physical events based on current data and create new technologies based on our discovery.

Description by Xin Zhao N. (Physics major at National University of Singapore)

Physics is the study of how things move and react. We can get a detailed as we want, looking at balls and atoms, but the same laws apply. Physics is also a mind-training exercise; you learn how to think about the world in an analytical way. It's this latter part that is the most difficult for students.

Description by Emily K. (Microbiology major at UConn)

Description by Diego V. (Especialista en Finanzas major at Universidad EAFIT)

Physics is the theory that explains the objects around us.

Description by Surendra M. (B Tech in Mechanical Engg major at Navodaya English Medium School, Nayudupeta)

Without going into much detail,let's think about few things which happens around us?

Anything thrown up falls back,
day and night follow ,seasons changes,
heating of objects on rubbing,
blue color of water in sea,
formation of rainbow,
moving back of object when we move forward in car.

What is common in all of them?
These all events occur according to some well defined laws and revealing these laws of nature by observing events is PHYSICS.

For e.g. falling of objects back to earth can be explained if we know Newton's Law Of Gravitation.

Now another question arises, how do we get to know these LAWS?
Very simple,just OBSERVE.

For e.g.-
Consider that you do not know anything about chess and you are made to observe a game between two players.
After watching the game for sometime you will cretainly be able to identify certain patterns , and on the basis of these patterns you will be able to identify why a particular player made a certain move.

However,it is quite dufficult.
Even if we know all the rules of chess,it is not so simple to understand all the complications of the game in a given situation and predict the correct move.

One may guess a wrong rule by partially wathcing a game.
Now, an experienced player may make use of a certain move for the first time & you'll be surprised.
Now,because of this new move,some of earlier guessed rules may prove to be wrong,
you'll forced to frame new rules.

Physics goes the same way.Nature around us is like big chessboard,it's different components-(sun,moon,oceans,galaxies,mountains etc) are the players,and events and phenomenons taking place in it are the MOVES of the game.
We observe this game of nature,guess rules and as and when we come across any such event which violates earlier rules we frame new ones.

Description by Tomasz O. (Applied Statistics major at Kennesaw State University)

Physics is the study of how energy and matter in the universe behaves.

Description by Michelle C. (Biomedical Engineering major at Johns Hopkins University)

Physics is, in my opinion, the quintessential science. We developed science to help us understand the world and make hypotheses about what it will do next. Physics is cool because we can easily see if we're right or not. If we calculate that a ball should suddenly jump off a table and accelerate towards the sky, we may have miscalculated something. The biggest mistake I see people make with physics is trying to do too much in their heads. That's what we have math for! When I see a student struggling with a problem, I usually tell them to just start writing valid mathematical statements and drawing diagrams that describe the situation, and often this will be enough to spark an idea.

Description by Ben H. (Mechanical Engineering, Chemistry Minor major at Georgia Institute of Technology)

It is the scientific study of matter and energy and how they interact with each other. This energy can take the form of motion, light, electricity, radiation, gravity .... For example, Heat is a form of energy.When you throw a ball from height, it falls down and reaches the earth due to gravity. This was experimented and proved by Newton.

Physics will take the math that you know and put it into perspective using the world around you. This could range from the largest star in the universe, to the smallest atom In the ocean, to making and testing designs for an invisibility cloak. With physics, the boundaries are limitless.

Physics is the study of nature. The universe is full of many strange and chaotic interactions and it is the goal of physics to describe the underlying patterns to these phenomena.

Description by Mac B. (Physics major at Michigan Tech University)

Physics, in a broader sense, is the study of how matter behaves in the natural world, and it covers everything from how an atom is held together to how light behaves to why galaxies don't fly apart. It is the study of all of the forces in the universe, and why our universe is the way it is. With all other sciences, if you were to keep asking "why" something happened, eventually, you would have to know physics in order to explain it.

Description by Evan H. (Physics major at University of California Santa Cruz)

In the most basic sense, physics is math applied to the study of matter and the natural world. It's a broad science, spanning from subatomic particles to the study of stars. At the high school level, it mainly refers to kinetics: the behavior of objects in motion, balance of forces, kinetic and potential energy, etc., but this is just a hint of what all of physics can be. The farther you go into physics, the more confusing and challenging it becomes (as with all subjects), but also the more interesting it becomes. Personally, I find physics fascinating, and the fact that breakthroughs are still being made in theoretical physics, particle physics, and astrophysics makes it even more exciting. I originally intended to be a physics major, before deciding that I'd rather do engineering (a little more practical).

Description by Finn v. (Chemical Engineering major at Brown University)

Why study Physics?

I believe that Physics is one of the most important things to learn about. The basic physics that you learn in even just the first couple years of classes can help you explain some of the fundamental laws which govern our universe. Even if all it does is make you good at billiards or playing catch, studying physics can be very useful in day-to-day life. Plus, everybody should have a decent understanding about how the world works, since we all have to live here.

Description by Alex N. (Mechanical Engineering major at Arizona State University)

Ever since its inception of this universe the laws of physics have played a major role. From the micro level of atoms till the size of planets and galaxies, everything is governed by the laws of physics.
Look at the world around us. Every day to day activity is seemingly imbibed with physics than we can imagine. For example, why is it more probable for a taller box to topple than a smaller box? It just has to do with center of mass. Even when we were kids and learning to walk this was what the brain was trying to figure out, "How should one leg be spaced from another, so that the person would not fall down?"
Look at gravity for instance. Some say it's just a force that attracts bodies towards each other while relativity states that its the distortion of space and time around an object which gives the isllusion of gravity. There are numerous phenomenon in the nature which would even awe a Science Fiction writer.
With multitude of applications (like electronics, cars) relying on Physics everyday it becomes very important to study and understand physics. With the more knowledge you acquire about physics, the more you will appreciate how the nature has beautifully designed this universe for us!!

Description by Guru D. (Electronics and Computer Sciences major at BITS Pilani)

Studying physics can help a person understand the physical world around them. For me, physics has helped me out in tennis. Knowing the conservation of angular momentum helps me visualize how and at what velocity my racket should hit the ball.

Description by Karthik G. (Biochemistry Molecular Biology major at Hendrix College)

Physics makes significant contributions through advances in new technologies that arise from theoretical breakthroughs. For example, advances in the understanding of electromagnetism or nuclear physics led directly to the development of new products which have dramatically transformed modern-day society, such as television, computers, domestic appliances, and nuclear weapons; advances in thermodynamics led to the development of industrialization; and advances in mechanics inspired the development of calculus.

To understand the massive amounts of energy that arise from fission of a nucleus. To set a foundation for a wide range of engineering fields.

To advance technology and society and understand the universe just slightly better than the previous generation.

Description by Mark D. (Math and Physics major at Massachusetts Institute of Technology (MIT))

My first two years in college I studied astrophysics. I eventually changed paths due to the limited career opportunities after graduation, but never lost the passion I had for it. Learning physics will make you think about the world in an entirely different way. Although it can be challenging at times, I have a knack for explaining things in a very simple and easy to understand way, because that is how I prefer to learn myself. I can definitely help if you are having problems with physics!

Description by Shephine S. (BSc. Physics major at Christ University)

Physics. At first as you go through your basic course, all you can think is why? Why am I learning all of these confusing concepts and strange formulas. Why? Because physics is the foundation for all science; Biology, Chemistry, any science. Any concept can be explained utilizing physics. And it's honestly, a beautiful thing. So why study physics? So you can put together the pieces you are given in your classes. So you can understand the world only described in your textbook.

Description by Sneha L. (Psychology major at University of Miami)

Physics is crucial to understanding the world around us, the world inside us, and the world beyond us. It is the most basic and fundamental science.
Physics challenges our imaginations with concepts like relativity and string theory, and it leads to great discoveries, like computers and lasers, that lead to technologies which change our lives—from healing joints, to curing cancer, to developing sustainable energy solutions.

Description by Sheik R. (BEng(Hons) Mechanical Engineering major at University of Mauritius)

Physics is the study of the world (and by that I mean Universe, as in absolutely everything) around us, and everything it cointains. Physics delves deep to know how things work (and, sometimes, even why they work that way), and, as I see it, knowing how thinks work is one of the best ways to know about something. Knowing about Physics, therefore, is vital for our understanding of the world.

Physics has many mind-blowing ideas somewhat hidden, to be deiscovered for the willing student.

Description by Borja L. (Computer Science major at Universidad Complutense de Madrid)

Physics explains why Wylie Coyote looks down and takes a big gulp before failing when he chases the road runner off of the cliff. Physics can be used in car accidents using conservation of energy and momentum to see how fast cars were going. Theme park designers use physics to help them create roller coasters using kinetic and potential energies. Physics will help you determine if you should add your creamer first or wait a while if you want to cool your coffee the fastest.

Physics is at the root of every major innovation in our society for the twentieth century. If you want to make a difference in society by building things, that's the way to go.

Description by Luis M. (Electrical Engineering major at Texas Tech University)

Physics is a very interesting subject. Although not seemingly useful to everyone, it does help explain why things happen the way they happen. There is something that is very unfortunate about physics. Once you start learning it and understanding it, then you start thinking about the reason that it something is happening. For example when a person watches a baseball game, you will realize that when the ball is hit, at it's highest point, it is called the apex and has a vertical speed of 0 m/s.

Physics is useful for engineering and general understanding of how the world works. If you aren't planning on using physics in your career of choice, it can still be helpful as it requires you to think critically and logically.

Description by Nicholas B. (Mathematics major at American University)

All the physical phenomena of nature that we see around us from subatomic particles behaviors to large scale universe are based on various laws of nature which can be understood scientifically if we study physics. The study of physics is basically an attempt to understand all these laws of nature. This is one of the most important reason for which we study physics. Besides, from the study of physics, we mankind can develop new technologies which are essential for sustenance of our race.

Description by Samananda K. (Particle Physics major at Manipur University (MU))

Physics may seem like just a bunch of equations but it is really about learning how to APPLY equations to best estimate how objects and items interact with each other.

Description by Sean B. (Biology, Physiology major at Georgetown University, Cornell University)

Because Physics explains how (almost) all things work. All the way from the big (galaxies and their formation), to the small (particles and how they interact)..

Description by Connor M. (Honors Physics major at University of Michigan)

Physics is the study of how the world works, from electricity to force, its one of the most abstract field and allows you to derive ideas about the world around you. It's tough but once you get the hang of it, its a fascinating topic which will pull you in!

Description by Roberto I. (Chemical Engineering/ Pre-med major at University of South Florida)

I'd like to first generalize this question to "Why study anything?"

Most of what is taught in school is not stuff you really need to know beyond passing the course, unless you're in a specialized training program such as your residency after medical school, a CPR class to become a personal trainer, flight school to become a pilot, etc..

Through all of your classes and a variety of content, your education will be spent learning how to learn, how to think, how to express yourself, how to work with others, how to navigate new problems, how to ask for help, how to appreciate the world from different perspectives, and how to question assumptions, among other valuable skills.

Physics will provide you with a great new perspective from which to view your world. It will also help you sharpen your problem-solving skills by forcing you to understand what you know, what you don't know, and how to bridge the gap between the two. Regardless of your goals in life, physics will provide you with a perspective unlike any other, and you just might have some fun along the way!

Description by Daniel P. (Physics major at Vassar College)

Physics is the what we see in our day to day life. We see them, appreciate them but we don't know what is the actual reason behind every thing.
To know the world more closely we need to Study Physics.

Description by Ravi R. (Computer Engineering major at National Institute of Technology,Surathkal)

Physics allows you to explain most motions, forces, vectors, electricity and magnetism, and physical observations related to planets and the universe. It also will allow you to predict how much force would be needed to break the earths gravitational forces and allow space flight. It can predict how the atoms are put together, how energy can be created that is locked up in matter, sun, and water.

Description by James V. (Chemistry major at University of Akron)

Physics provides you with the theory of how the world works. You find out how objects move and understand the foundations for many other subjects. Understanding physics will often help you understand other subjects better.

Description by Steven C. (2A major at Massachusetts Institute of Technology (MIT))

Everyone needs physics to really understand the sophisticated facts of life on this planet. For example, at the very basic level, understanding newtons laws allow us to judge the harmful impact of falling down. More complex physics, like electromagnetism, explains to us how generators and motors function. I guarantee whomever that learning more about physics will make you crave it more. Nothing is more fulfilling than understand your surroundings and the laws that govern what you see.

Description by Hadi Z. (Materials Science and Engineering major at Massachusetts Institute of Technology (MIT))

Physics is an advanced science that boils down to the fundamental study of matter. Using the language of mathematics, physics can help to describe and explain the world around us. Two major branches of physics are Classical Mechanics, which studies concepts such as kinematics, Newton's Laws, and gravitation, and Electricity and Magnetism, which studies concepts such as electrical circuits, magnets, and Faraday's Law's. The concepts of physics can be taught to any student with an algebraic background, but also can be taught through the tools of calculus. Many physics problems boil down into applied math problems, so for any test, homework or project, I can help you break down any physics problem and solve it mathematically. In addition to the mathematical understanding, I can also work to give you a conceptual, scientific idea of what physics is.

Description by Nikhil P. (Mathematics and Economics major at Brown University)

Physics relates how everything in the universe interacts. Physics describes the most basic forces and how they relate to other scientific fields. It is required to fully understand the other sciences. For example, the optics section of physics discusses converging lenses and how they work. When looking at the anatomy and physiology of the human eye, the lens of the eye is a converging lens, and physics will tell you where the lens focal point is. The focal point of the eye will then begin the neural communication to convert the image into something your brain understands.

Description by Katlin C. (Biology and Chemistry major at East Tennessee State University, Johnson City, TN)

Physics is the study of EVERYTHING! It's considered the purest science because all other sciences owe their knowledge to the study of physics. If it wasn't for Physics, there would be no biology, chemistry, environmental science, marine biology, or, on some level, even psychology for that matter! Physics breaks down incredibly complicated topics like shooting nerf guns, lasers and mirrors, electricity, sky diving, hydraulic pumps, and so much more and turns them into a series of small equations! Physics tells us how atoms operate, how far a football will go, and how water stays in a bucket as you swing it in a circle! Sure, the math can be difficult at times, but with a little practice, you'll be keeping your units straight and learning to love the wide world of physics!

Description by Nicholas H. (Biology major at The University of North Carolina at Greensboro)

Studying physics allows us to understand the world around us in a concrete way. By applying math to the physical world, not only can it allow us to predict what will happen in certain situations, but also why things happen as they do.

Description by Erica B. (Industrial Engineering major at Oregon State University)

Very interesting

Description by Yonghui Z. (Mechanical Engineering major at National University of Singapore)

Physics is the study of physical phenomena. It can be useful for describing the interactions of the very large to the sub-atomic.

Description by Lukas D. (Physics major at The Principia)

Physics is a subject which you encounter many times in your day to day life. Right from the morning you get up till you go to bed is all Physics.

Description by Manas D. (Electronics, Biomedical major at IIT Bombay)

Physics is how we view the world around us. It is how we decide just what angle and time to throw a baby in order to hit the car that is passing at 25 m/s. It is how we calculate the power required to heat up a light to a point that would cause bodily harm. Everything we do involves physics, and it can be fun and exciting to learn about.

Description by Brandon D. (Aerospace Engineering major at University of Maryland)

Physics describes the fundamentals of how things interact with each other. A basic understanding of physics helps one grasp many different phenomena including electricity, magnetism, chemistry, statics, and dynamics. These are the building blocks of almost every STEM field and technology based career.

Description by Adam A. (Chemical Engineering major at Brigham Young University)

Simply put: The study of objects and things in motion and their impact on the environment.

Description by Jason Q. (Molecular and Cellular Pharmacology major at Stony Brook University)

People has been asking the big questions of life, the universe and everything. Pure philosophy cannot get you very far at all if you don't look at experimental data. Physics is the natural science to lean to for the search. The answer will be more than just 42 as given by the hitchhiker's guide to the galaxy. Yet, to fully answer it we need the real theory of quantum gravity, of which there are many out there now, awaiting confirmation. So why study Physics? To help in the discovery of which is the real quantum gravity if any exist.

Description by Xin Zhao N. (Physics major at National University of Singapore)

Physics is not only a tool we can use to build (hmmm,pretty much) everything, it is also for me a very different way of looking at the world to find the hidden mysteries that govern how everything behaves (physically :) )

Description by Miaoyuan L. (physics major at Duke University)

Physics is the the subject that help us to understand how the world around us works. It gives the information about natural phenomena of daily experience like gravity, light, stars, storms, earthquakes etc.

Description by Ranveer K. (Physics major at Periyar University)

Physics is the natural science that helps us study and understand nature better. We knowingly or unknowingly do a lot physical activities that we can correlate with our Physics. Every work we do in our day to day life is a combination of a few laws of physics. We can apply laws of physics in basic activities like walking etc., Learning physics makes our life better and easier. A small and interesting example for this is regarding a concept that Pulling an object is easier than Pushing. Drawing a Force body diagram and analysing it we can easily conclude this. After learning this one would try to pull rather than push. Learning physics is one never ending innovative studies. It is the study of several scientists that we are today enjoying a life electricity, motor vehicles, multi storey buildings.

Description by Vamsidhar N. (Civil Engineering major at Birla Institute of Technology & Science)

Studying physics provides you with the ability to understand everything you can see in the world around you. It is the scientific language that explains the building blocks and giant structures of the universe. The laws of physics govern all other disciplines of science, at least indirectly, so they are very important to learn! In addition to its importance, physics is also fun! Understanding physics will change the way you look at the world more than any other scientific discipline!

Description by Sam M. (History and Spanish double major major at University of Vermont)

Physics is the study of matter and energy. Each time I see the picture of Albert Einstein and his famous equation E = mc2 (the 2 should be in exponential form and my typing did not allow me to.) these always remind me the interesting facts that Mr. Einstein had contributed to the study of the relationship of matter and energy. I always ask myself the "How question" in almost everything that I see around me, and somehow, everything is governed by certain Physical Laws. To me, that made the study interesting!

These are the branches of Physics and their definitions.
Classical Physics
Classical Mechanics (Newtonian Mechanics)- study of motion and forces.
Electromagnetism- Study of electricity and magnetism.
Statistical Mechanics- Study of theoretical predictions on the behavior of macroscopic system based on statistical law that govern its component particles.
Acoustics- Study of production, control, transmission, reception, and effects of sounds.
Thermodynamics- study of heat, temperature and energy.
Optics- Study of nature, properties of light, and optical instruments.

Modern Physics
Relativity- Study of motion near the speed of light and space-time geometry.
Quantum Mechanics- Study of motion of very small particles.
Atomic Physics- Study of structure and behavior of atoms.
Molecular Physics- Study of structure and behavior of molecules
Particle Physics (High-energy Physics)- Study of structure and behavior of subatomic and fundamental particles.
Condensed Matter Physics- Study of properties of bulk matter such as solids and liquids.
Astrophysics- study of the behavior, physical properties, and dynamic processes of celestial objects and phenomena.

IT is important to study physics because it incorporates fundamental theories required for technological advancements.

Description by Mian H. (Biological Chemistry major at University of Toronto Mississauga)

We are born into a world that is as fascinating as it is mysterious. When we arrive we know nothing, but those that have lived before us have begun to learn about how it works and recorded their findings so we can know too. Bit-by-bit humans are uncovering more and more mysteries of the universe, and with each discovery the human race becomes empowered. When we understand we gain an element of mastery over it, and eventually we can bend the universe to our will!

The computer in front of you would have been completely alien to people living only a few hundred years ago. It would have been considered a supernatural phenomenon, possibly either miraculous or demonic! Yet each and every component within it is created as a result of a deep understanding of the rules of the universe, and in creating it humans have forced the atoms in it to behave exactly as desired. Ways that they would never have behaved without us. Ways that even trick our own minds to see worlds before us that exist elsewhere only in the minds of others. It is only one example of humans controlling the world with their knowledge but there are countless others...think of all the incredible technology that is now part of our modern lives.

It is said that knowledge is power, and physics is knowledge of the universe. So a physicist can truly be considered a master of the universe, and you can be one too...

Description by James M. (Physics major at Imperial College London)

Most of the phenomena in nature are/can be described with physical theories. Physics can be divided to different categories from different perspectives and they all span the whole range of events in our universe:
1. Energy scale (Velocity of particles; from classical physics to relativistic)
from small energies (thermal fluctuations in Biophysics) to medium energies (ordinary and everyday events: Mechanics) to High energy Physics (Particle Physics and Cosmology)
2. Size scales:
very small sizes (Quantum Mechanics). Nano scale (Nano physics), Classical (Meter scale) Cosmology (Whole Universe)

Description by Ghazal M. (Physics major at University of Michigan)

Physics is interesting.
Physics helps us to organize the universe.
Physics helps us to understand how the world around us works, from can openers, light bulbs and universe, etc.,

Description by Swathy S. (BSc Physics major at Anna Adarsh College for Women, Chennai (Madras))

To understand the workings of this world, we need to understand the forces, the mechanics, the entropy, the energy of the system. Physics does just that for you.

Description by Mahesh A. (Mathematics major at IIT Kanpur)

The great thing about Physics is you can apply it to almost everything you do. For example, throwing a ball. Whether you know it or not, your brain is making calculations on how much energy your arm should expel to get that ball as far as you need it to go. Sounds like Projectiles (motion and force).
Once you learn how to manipulate the energy around you, you can build something to throw that ball for you.

Description by Amanda I. (Electrical and Electronic Engineering major at University of Manchester)

Because the physics can describe us, any thing we see, what we do, or the place we live in.

Description by an InstaEDU tutor

Physics helps engineers design high-tech products. Furthermore, it is interesting to understand the fundamental workings of the universe.

Description by Philip L. (Mathematics with a specialization in Economics major at University of Chicago)

Physics, the most fundamental science, is both challenging and rewarding. It's fascinating because you get to find out how the universe works at the most basic level. The fact that it's challenging is also great! You get to prove your intellect, in particular your ability to break down and solve complicated problems to future employers.In studying [hysics you develop a broad range of skill and for this reason It is well regarded in many quantative industries.

Description by Lauren A. (Particle Physics major at University of Oxford)

It might be easier to describe the few reasons that Physics is not interesting. Well I love Physics because I get to talk about skydiving, bungee jumping, race car driving, sound waves, light being a particle and a wave, and even the idea of time travel. Physics covers all of the things you always wonder about and it gives you the mathematical background to make predictions about that behavior.

Description by Matt T. (Biology major at West Texas A&M University)

Because physics tells us how everything works in this world.

Description by Hans L. (Applied Mathematics & Business Economics major at University of California, Los Angeles)

Studying physics allows you to understand the world around you. Physics explains why and how the world behaves. Studying physics allows you to predict what will happen in the world and why. Also, you can learn how to manipulate the world around you in experiments.

Description by Kayla G. (Biomedical Engineering major at Johns Hopkins University)

Understanding physics is easier than most people make it out to be. Yes, eventually one has to get into complex math in order to understand some of the more complex and modern ideas that are used to explain the finest and rarest minutia of phenomena in our universe, but nothing more than basic algebra and a conceptual understanding is needed to reason how the world around you works, and being able to put that together is fascinating.

Description by Evan H. (Physics major at University of California Santa Cruz)

Because it's how the world works! Physics is the most pure of natural sciences, and is the basis of basically every scientific innovation, either directly or indirectly. It's practical and fascinating. Whether you're building things, trying to understand the interactions of atoms, or pondering the stars, physics opens up endless possibilities. I don't think any scientific education is complete without a solid basis in physics.
