How Students Learning physics?

 How Students Learning  physics?

      If you're just starting to learning physics then the (Halliday-Resnick textbook) is what is used in universities, and frankly due to the breadth of the field, there's not really a way around reading lots of books and working on lots of problems.

Use the Internet and your local library to have access to electronic and physical texts. Would recommend using an introductory text as your starting guide and searching online for more information on what interests you.

Note that physics is very mathematical, so you'll need to learn multivariate calculus and complex analysis if you go far enough. Physics is the mother of all sciences, Want to understand how chemistry works? Learn physics. Want to understand how biology works? Learn physics. There are few scientific, technical, or mechanical disciplines where a basic understanding of physics won't improve your abilities.

Physics is the answer key to how the universe works. Why will my car skid on a wet road? Physics can tell us. How does my microwave oven heat my food? Physics can tell us.

Still thinking "I don't care."? if unlocking the universe isn't motivating enough, let's get more pragmatic. One of the most important things a school can teach its students is problem solving skills, Success in life requires being able to approach a problem, analyze that problem, identify the variables and their relationships, and arrive at a solution, Learning a skill such as problem solving requires repeated exercising of the skill, in more and more challenging ways. 
 
 we could waste time in some boring abstract math class solving generic problems - but physics presents us with real problems that are transferable to our lives, not abstractions. Going to build a shelf in your den? Might be nice to be able to figure out how much weight it can hold. Going to drive in the rain? It might be nice to understand why you should leave more room between you and the next car, when the roads are wet.

How about the desire to have an informed electorate? Want any hope of understanding whether climate change theories are real or not and whether the solutions of politicians will work? A basic understanding of physics allows that, you want to understand why it costs so much to put a satellite in orbit? A basic understanding of physics allows that. Want to understand why investment in infrastructure, like maintaining bridges, is a critical use of tax dollars? A basic understanding of physics allows that.

Understanding physics opens our eyes to the world around us and creates an epiphany in much the same way that learning to read does, everything becomes more clear and accessible.

Anyone with an interest in physics can learn from reading the Feynman Lectures, These are remarkable works; chock full of depth, insight, novel approaches to timeless subjects, and good ideas, Written for the basic physics course at Caltech, they can amuse and educate a professional physicist. They are accessible but NOT easy. Feynman's easy, colloquial style masks the depth of thought in them. My personal favorites of the Feynman series are:



1- The basic mechanics lectures and the discussion of kinetics in Vol

2- The approach to relativistic E and M, the discussion of fluids and the special lecture on the Principle of Least Action in (Vol).

3- Feynman's approach to QM in Vol 3, which avoids getting mired in cranking out details of solutions to the Schrodinger equation.



These lectures are unique masterpieces. The real question is not if but how does one learn from them? That depends on the reader.

For the casual reader – just enjoy, but I'd suggest trying to tie your reading into some books which ask you to answer questions or explain what was read. The book”50 Great Physics Ideas You Really Need to Know" is a good one for this – and has thought questions. Some of the most accessible Feynman lectures appear in the short book "Six Easy Pieces" (Six Easy Pieces: Essentials of Physics Explained by Its Most Brilliant Teacher This is a good way to start reading Feynman. My view is that this book is a better investment of time and money than nearly all of the popular books on physics on the market today.

For students studying basic physics, the most essential thing missing from Feynman is problems. These are essential to learning. The serious student should note that the Feynman Lectures are subtle. See the comment in the preface about how poorly the students did on the final exam – and that was Cal tech! Hence its important to keep one's feet on the ground by exercising and testing one's understanding. Now the Feynman Lectures do have a problem book (Feynman's Tips on Physics: Reflections, Advice, Insights, and Practice – A Problem-Solving. This is useful, but still rather idiosyncratic. Thus, it’s good that there are also some challenging books of quite high quality which can be used as supplements to the Feynman Lectures – both for problems and explanation. All are well above the usual freshman physics texts.

To learning physics online:

I can suggest you a list of free online physic courses: Fields at State University of New York - Stony Brook ,Fields is an online physics textbook written by Professor Warren Siegel of SUNY - Stony Brook. The text focuses specifically on quantum field theory and claims to discuss standard topics of field theory in a fresh, new way. It also features working hyperlinks to referenced papers.

Fundamentals of Physics I at Yale University This Open Yale course consists of 24 class sessions. Each session has an audio lecture, video lecture and transcript, as well as assignments with solutions, Students will learn about basic principles of physics, including gravity, thermodynamics, relativity and waves. A textbook is required to get the most out of the course.
General Physics I at University of Michigan

Students are introduced to mechanics in this course, with topics including Newton's laws and angular momentum. They can download lecture notes and exam reviews. Students can also access interactive exercises that demonstrate various principles.

Interactive Simulations at University of Colorado - Boulder
This site offers more than 90 online simulations of physics experiments. Students can manipulate data to test band structure, charges and fields, friction and other types of scientific phenomena related to physics. The simulations come with teacher's guides for learning.

Introduction to Modern Physics at University In this undergraduate course, students look at relativity and explore the principles of quantum mechanics. They can download slides of lecture notes and several years of exams and solutions. Topics covered include electron waves, atoms, molecules and radiation. A textbook is required, and other readings are recommended, to fully learn from the course.

Much easier and cheaper way is learning by yourself, when you read books and do different experiments, or if you can't do experiments at home you can use special app - Step.
 

 Why should we learn physics?

   It is something inherently beautiful that quiets your brain without asking for feelings and can be inspirational and meditating at the same time. Physics has changed the way I see the world around me every day and the way I communicate with people. When I face challenges in life, I do not see those as problems anymore but really as challenges which can be solved, I became much better in planning and still be able to improvise in the last years of my studies. Still sometimes it sucks when you want to do sport and always have angular moment in your head or think how the floor could converge dancing into energy and how the maximum of energy would be reached if all people danced in sync during aerobics. So much for the daily life stuff .


The real stuff, when you ask yourself why plants have green leaves that brings you to photosynthesis and biophysics, When you wonder why you are sad, depressed, in love or other stuff that brings you to biochemistry which can be modeled by quantum mechanics. If you ask for cancer cures you end up with molecular dynamics simulation of proteins. If you ask for people never being able to read your digital diary you want to ask for better encryption which can bring you to quantum computing. Ever wondered why things have a color, how the perception of light works or why the sky is blue? Try physics, what happens if you rode a light beam? Ask relativity.

As I am interested more in chemistry and quantum mechanics most of my examples are related to that. An engineer will tell you more about electrodynamics. Still it is fun to imagine that you can run around and there is this one thing no one can take from you in life - logic thinking.
