Hello PhysicsForums!
I am a Physics/Math double major undergraduate junior. I've always loved math, and to study the universe; so I decided to combine both and become a physicist! I did my Gen Phys 1-2 (with Calc) and most of my math at a state college and then I transferred to a university...
I'm preparing for my Foundations of Geometry Course by self-learning topics before the semester starts. I've been reading Geometry: A Comprehensive Course by Dan Pedoe, and it's covered a lot of good topics. Any online resources you recommend?
Not sure if this was posted but I came across a fairly recent online journal specializing on Quantum foundations that some might find interesting:

I'm getting interested in mathematics because as a philosopher I am upset with the amazingly poor standards of rigor in my field. I am looking to mathematics for guidance. I would like to formalize philosophy and turn it into a deductive science. I have a deep interest in logic so I decided...
If you have seen interesting recent research papers on foundations/interpretation of these branches of physics, please share your links and thoughts. Argument along ontic versus epistemic lines is not approved--it is frequently a waste of time. So if you please use a separate thread if your...
Folks,
A friend and I are interested in finding a forum to discuss the philosophy of the foundations of mathematics. He's a mathematician and I'm a mathematical physicist. Some of the topics we're interested in are understanding intuitionism and understanding Wittgenstein's lectures on the...

(Submitted on 9 Aug 2013)
We propose an approach to quantum theory based on the energetic causal sets, introduced in Cortês and Smolin (2013). Fundamental processes are causal sets whose...
I finished reading "Linear Operators for QM" by Jordan a couple of weeks ago, and it was extremely interesting for me. It introduced various topics in functional analysis that are relevant to the foundations of QM (Hilbert spaces, spectral theory, von Neumann algebras, etc.).
I was wondering...
1.How did the nucleus evolve?
2.What are the pointers indicating the evolution of eukaryotes from the same branch as archea?
3.Obligate anaerobes, what is the end products? Does it include molecular oxygen? What is it in case of facultative anaerobes? Is there any organism that uses a...

Hello,
I'm a first year graduate student, and one of the required texts for my class is the book alluded to in the title. However, it seems to me that this book is written in the language of a mathematician, and is a bit inaccessible to me. Particularly, I'm having trouble following the...

On the Foundations of Superstring Theory
Gerard ’t Hooft
Abstract: Superstring theory is an extension of conventional quantum field theory that allows for stringlike and branelike material objects...
The short summary is that my high school foundations of math were absolutely terrible as I was instructed from the youngest age that mathematics was entirely about computation and that being talented in math meant being able to handle lots of number grinding in your head without a calculator. I...
Homework Statement
Prove the following. 4+1+4^-1+4^-2...4^-k = 16/3-1/(3)(4^k)
Homework Equations
The Attempt at a Solution
I confirmed the basis step and proceeded by changing the variable to n and adding n+1. I now have (16/3) - (1/(3)(4^k)) + (1/4^k+1) = 16/3 - (1/(3)(4^k+1))...
I'm looking for a good text on the foundations of GR. Geared towards physicists, but with a focus on the subtleties of the ideas that went into building the theory rather than on applications. Any recommendations? Thanks!
It's known at anyone that, the QM is a powerful instrument investigation about the microworld...since 1930, official year born, the QM has explained a lot of mysterious facts, revealing strange behavior of the mother nature... physicists love QM to the simply mathematical and for the amount...
Hello,
Does anyone know of any good books that covers the foundations of mathematics (i.e. mathematical logic, axiomatic set theory, proof theory, model theory, type theory, recursion theory...)?
Keeping in mind that I'm still in high school. (Although I'm taking math courses at my local...
Hello.
I would like to bring to discussion this paper called "Mathematical Foundations of the Relativistic Theory of Quantum Gravity", by Professor Fran de Aquino, from the Maranhao State University, in Brazil.
The paper was published in the Pacific Journal of Science and Technology...
Well this post is "related" two math but I found the chat room to be the most appropriate place for this.
Now I found a lecture series on youtube by a mathematician N J Wildberger.
He claims that the "Foundations of mathematics" are flawed. The area of mathematics he claims need to be revised...

Standard treatments (e.g., Rindler) of the foundations of Special Relativity invoke use of a "rigid rod" or "rigid scale" by an observer to construct his inertial frame -- by (somewhat fictionally) transporting the rod (and also cloning copies of a standard clock at every point in the frame)...
Hey Everyone,
I just wanted to ask for a bit of help on this research assignment I have to do. I have to show how Fractal Geometry contributes to the theory that Mathematics was invented. I have been looking into fractal dimensions and the fact that the dimensions we have labelled (1,2 and 3)...
I was intrigued reading * http://en.wikipedia.org/wiki/Quantity_calculus" that after two centuries axiomatization of QC has not been completed, though there are only 5 basic elements and 4[3] concepts:
S[tandard],= U[nit], D[imension], Q[uantity]. I suppose nobody here has tackled the problem...
It is frequently stated that path integral formulation of quantum mechanics is equivalent to the more traditional canonical quantization.
However, I don't think it is really true. I claim that, unlike canonical quantization, path integral quantization is not self-sufficient. That's because...
Is Abraham and Marsden's Foundations of Mechanics a good book to learn Classical Mechanics? In other words, if I were to go through this book (which I believe is more mathematical than physics-related) would I have a good, intuitive grasp of Classical Mechanics?
Hello, I'm a rising Junior at UC Berkeley, and I'm in a bit of a dilemma for the upcoming semester. I'm a math major, and intend to go to graduate school to pursue a Ph.D in Pure Math, but am not sure about the best path to take. Right now, I've completed the upper division Linear Algebra...
What role does the anthropic principle play in modern cosmology? How can we justify it? (Is it merely good old common sense or does it have a mathematical formulation?) What does it succeed in explaining? Is it scientific? Is it necessary?
After looking at the axiomatic systems of modern mathematics and asking myself what proves they are self consistent I went looking for an explanation and so far I have found only that they have not been proven self consistent nor likely will a proof ever exist. So the possibility of a...
Foundations of "Formal Limits"
In Spivak's 4th Edition, one examples says:
"The function f(x) = x2 is a little more interesting. Presumably, we should be able to show that f(x) approaches 9 near 3. This means that we need to be small enough to show how to ensure the inequality...
Dear All,
Recently I have published a paper on Bell's theorem ASTP 4(20) 945-949 (2010). One can also find it on arXiv as http://arxiv.org/abs/1012.4990.
I am interested in a discussion about the results of the paper. The claim of the paper is that mathematically Bell's theorem is...
Hey,
I would like to start a discussion about the use of set theory in mathematical physics. I myself have done research in categorical physics and have seen the debates on how it can be an alternate foundation for mathematics. We can discuss here a few things, but try to stick to these...

Hello,
Recently I've been attempting to put together a brief book on mathematics. The first section is short and introductory as I lead up into calculus. I kind of feel bad that I skipped over conics, geometric series, permutations and combinations, transformations of functions, and so many...
A discussion arose tonight about why spacers aren't used in the foundations in houses, as opposed to sidewalks where there are gaps every few feet to allow for thermal expansion. Some possible answers were that the foundation would be more constant temperature, or that the concrete was somehow...

I took the first term of a Foundations of Physics sequence (251) last year, and understood most of the material fairly well. It was calculus based Newtonian mechanics; units and vectors; one-dimensional motion; Newton’s laws; work and energy; momentum and collisions. Since it's been a year...
I enjoy Physics like many and always keep an eye out for new discoveries, but is our understanding of the universe becoming too complicated and involved.

I'd liked to know whether the postulates of standard QM are still valid in Relativistic QM
By postulates I mean what is ussually stated in texbooks as follows

It is a well known view that mathematical logic together with set theory can be used as a foundation for the whole the rest of mathematics. Category theory also has been mentioned as a candidate for this, as an alternative of set theory.
But recently I heard (from a non-mathematician) a view...
Hello,

Conjecture: Most of the people doing research in the foundations of maths are 'not good enough' for maths.
conjecture here is obviously a joke (but not completely).
not good enough as in feel that maths is too difficult to understand (i.e not clear enough, too abstract).
There's obviously also...
