Dear Physics Forum personnel, I am a undergraduate student with math and CS major who is currently taking an introductory analysis course called MATH 521 (Rudin-PMA). On the next semester, I will be taking the course called MATH 522, which is a sequel to 521. My impression is that 522 will be...

Do you know of a resource that expunges all theory and all mathematics and focuses solely on observable facts? Example: This resource would list Faradays experiments but leave out Maxwells equations.

I am reading a book abut tennis physics and I have seen a result that I feel is wrong. We have a tennis ball and a racket, and several cases: 1.- Ball hitting stacionary racquet that is sustained with your hand. (I agree with the results of the book here, it is just to show how they are...

I started with Mary Boas' book "Mathematical Methods in the Physical Sciences". Now it is stressed in the introduction to make homework and do the problems. However, I would very much like to know if I got the answers right, and I even prefer if the problems are worked-out. So I guess my...

Hi, I'm embarking on a mission to self-study math, and would like some recommendations on any missing books or ones that should be replaced in my repertoire. The goal is to build a strong mathematical foundation. My naive idea of what that means is something like an undergraduate math major, so...

(sorry my bad english). I was reading a Halliday's book of phyisics awhat I found is below. d(72t²)/dt = 144t why did the result was 144? It has anything to do with the deltas in the equation (d and dt)? and second I don't realize why the result of this another equation is this 4t²+2t+3 = 8t+2

I need a good book on differential equations.

Text says that threonine and isoleucine have a chiral carbon in sidechain. I am not seeing it. The carbon in the sidechain that is next to the alpha carbon is attached to an oxygen, a hydrogen, a carbon (a methyl group) and the alpha carbon. So that means its attached to two carbons, so...

What would be a good book that starts with the Peano axioms about the natural numbers and constructs, rigorously, the natural numbers, whole numbers, integers, rationals, reals, and finally complexes? I would prefer it if the book did not leave out major steps, but instead went in a logical...

So, I know that there is a Normal force exerted on the book by the table, and, according to Newton's Third Law, the book exerts a force onto the table. However, I have two questions: if I were to push down on the book, would that Normal force increase? What "creates" the Normal force? Is it the...

Homework Statement Newton's third law of motion is often summarised as 'Every action (force) has an equal and opposite reaction'. A book rests on a table. If the weight of the book is the 'action' force, what is the 'reaction' force? A the pull of the book on the Earth B the pull of...
