From a post by Mathwonk in the recent thread about randomness in prime numbers:
Barry Mazur's article on "Error Terms" in the current issue of the Bulliten of the AMS (BAMS) uses the "Prime Number Races" that Mathwonk is talking about as a "jumping off point."

Has anybody read Barry Mazur's article in the current issue of the Bulliten of the AMS?

Here are my thoughts:

1) Mazur references the excellent Prime Race article quoted by Mathwonk above. This raises the following questions.

A) Did Mathwonk get the reference to the monthly article from Mazur?
B) Did Mazur get the reference from Mathwonk?
C) Is Mathwonk really Barry Mazur?

2) Mazur's article gives a really good introduction to modern number theory for non-number theory specialists like me. For example, he has an elementary introduction to Galois deformations, one of the primary highly specialized techniques that Wiles used to prove FLT.

3) Mazur gives really understandable explanations of the links between
A) Prime Races
B) the (yet to be found) proof of the Riemann hypothesis
C) elliptic modular functions
D) L-series
E) Wiles proof of FLT

4) Mazur makes it seem to me (although he does not say this) that it is highly likely that the same body of knowledge that allowed Wiles to prove FLT will allow some genius to prove the Riemann conjecture in the near future (or, at least in this century).

5) Before reading Mazur's article, I was slowly becoming convincedc that the Langlands program was key in Wiles proof and will be even more key in future breakthroughs. After reading Mazur's article, I feel even more strongly this way.

6) The equivalence of demonstrating suspected magnitudes of various error terms to the Riemann hypothesis sure looks like a promising approach to resolving the Riemann hypothesis.

7) Note that I said "resolving" and not "proving" the RH. Even the experts admit that, at this point in time, it's an even bet. This is not true of the FLT before Wiles proved it. After Ribet's work, everybody was pretty sure it was true. Everybody who followed Ribet's work, that is.

Link: Barry Mazur's Finding meaning in error terms.

As for your #7, I don't get that impression at all. I think not even 10% of of computer scientists think that $\mathcal{P}=\mathcal{NP}$, and I think that many fewer mathematicians think that RH is false.

Greathouse,

So, what was your reaction, or, some of your reactions, to Mazur's article?

Did you experience the same feelings that I expressed in #1 - #6?

Or, is the jury still out?

I don't have any quarrel with your statement about P != NP being the common opinion. I don't think I addressed that point in my write-up, but I more-or-less agree with you (my only caveat being the growing number who suspect it might be undecidable, in which case, the words "true" and "false" take on very strange meaning. Reference: the interview with Martin Davis in one of the recent issues of the Notices of the AMS.

I also really have no basis to disagree with your statement about "the majority of mathematicians." That was not my claim, of course, so the impression you have about the "majority of mathematicians" thinking it is true does not contradict the impression that I have that "the experts agree that it is a 50-50 bet."

In fact, I'm glad you bought the subject up. I didn't want to take up space laying out the information on which I base my impression about the "opinion of the experts" on the RH if nobody was interested.

But, not in this post. I have to get some stuff together first. I hope I can dig up what I am looking for.
