How do you decide whether a question in abstract algebra is worth studying?

I'm going to interpret your question in the language of Gowers's "two cultures" essay as follows: How does one get good at theory-building? The process of developing a good theory can seem decep …

How would you have answered Richard Feynman's challenge?

There's a certain gaming/sporting aspect to Feynman's challenge that works in his favor. First of all, as phrased, the challenge gives him a 50/50 shot at being right even if he guesses randomly. Al …

When is one 'ready' to make original contributions to mathematics?

It is something of a myth that everything has already been studied and that you have to master thousands of pages of prior work before you can contribute something new. To be sure, there are some sub …

The editor wrote the paper for me

[Comments combined into a community wiki answer.] Copyright is the wrong word in this context; the correct word is authorship. A reasonable course of action is to propose to the editor that you and h …

Old books you would like to have reprinted with high-quality typesetting

I have some experience resurrecting old math books and I want to make a few comments about copyright. First, it is definitely true that except for very old books, someone owns the copyright. Typicall …

Request for examples: verifying vs understanding proofs

Don Zagier has a well-known paper, A one-sentence proof that every prime $p\equiv 1\pmod 4$ is a sum of two squares. An undergraduate mathematics major should be able to verify that this proof is cor …

Extent of “unscientific”, and of wrong, papers in research mathematics

As Kevin Buzzard himself admits in his answer, he somewhat exaggerated his point for effect. However, I'd submit that if you were unsettled by his talk, then that's a good thing. I don't think that …
