Pro Mathematicians: how familiar have you remained with the material covered throughout your undergrad? (Outside your field)

Outside of your field of research / application, how much of your undergrad education have you retained? Thought experiment: How would you fare today if handed old exams from your introductory topology / number theory / differential equations /…

Where are the geometric figures in those "advanced geometry" textbooks?

It is me again to bother you. Since my last post I started to look at some seemingly "serious" mathematics for background study. Accidentally I went into a university bookshop and came across some "differential geometry", "algebraic geometry",…

What would be a good way to memorize theorems about algebra?

This post is not constructive, so maybe this rather should be posted on CW, but since there is a 'soft-question' tag, i'm posting it here. ===================== I believe the best way to memorize theorems is to draw. It was not hard to illustrate…

Is proofwiki.org a reliable source of math proofs?

Is proofwiki.org a reliable source of math proofs? I'm inspired by this question about wikipedia. This site has much less traffic and not very known, but it appears in some google search about math, and I wonder your "subjective opinion",…

Opposite of Fermat's Last Theorem?

So Wiles' proof showed that no three positive integers $a$, $b$, and $c$ can solve the equation $a^n+b^n=c^n$ for any integer value of $n$ greater than $2$. Now what about the opposite? What does this mean for any $a$ greater than $2$, and $x$, $y$…

What does "rigorous proof" mean?

I have heard several times that some mathematician has given another and more rigorous for an established theorem, but I don't know what does it really mean and what differences makes it to be more 'rigorous'. My understanding of a proof is that a…

How to prove existence of solutions without constructing one?

For some problems, it is difficult to get an explicit solution. But it is very good if we can prove there do exist some solutions though we can't find them. Is it possible to prove existence of solutions without constructing one? Can you show some…

Is our interest in $\mathbb{R}$ "historical"?

In the process of a topology course, it occurred to me that a number of concepts are defined with reference to $\mathbb{R}$ and standard subsets thereof. For instance, we consider metrics, which are of course maps into $\mathbb{R}$ (specifically the…

Studying Graduate Level Mathematics Outside Lecture Hours

I am not exactly sure if this should be posted on math.se or academia.se, but I think the question is more mathematical in nature. I am a first year graduate student in mathematics, and I would like to think that I am a diligent student at that. My…

Do people whose native languages are read right-to-left experience mathematical statements differently?

When I see the equation $$A = B$$ the first idea to occur to me is that $A$ can be transformed into $B$. Although of course $$B = A$$ has the same content, to me it connotes rather that $B$ can be transformed into $A$. I imagine that this is because…

I see people like Terry Tao and others take extensive notes. But is this really necessary? When I do this I feel like I am rewriting a textbook.

Is it usual that a professor never proves a theorem in a class?

I'm taking "real analysis" this year and the lecturer's major is PDE. What he does is literally reading texts except proofs. This drives me crazy, so I asked the professor why he is not giving any proofs, and then he told me, "I'm not interested in…
