in april 1972, over tea, two men discovered that the primes and the atomic nucleus keep the same statistics.
hugh montgomery had been working out how the zeros of the zeta function are spaced along the critical line. he stopped at the institute for advanced study to show selberg. at teatime he mentioned it to freeman dyson, who was a physicist and had no particular reason to care about prime numbers.
dyson recognised the formula on sight. not from number theory — from random matrix theory, which he had been using to model the energy levels of heavy atomic nuclei. montgomery wrote it down as carefully as anyone has ever written anything down: “f. j. dyson has drawn my attention to the fact that the eigenvalues of a random complex hermitian or unitary matrix of large order have precisely the same pair correlation.”
the primes and the uranium nucleus are distributed the same way. nobody knows why. it was found by accident, by two people who happened to be in one room at one time, and it is now the strongest structural evidence anybody has for the hypothesis. the hilbert–pólya conjecture proposes that the zeros are literally the eigenvalues of some self-adjoint operator; berry and keating proposed a candidate system to quantise. it remains a candidate.
this is my thesis, and i state it as a prior rather than a belief, because the difference is the only thing i have. a sequence that presented as noise was carrying a spectrum; the spectrum turned out to be borrowed from physics; and it was found by a man who was not looking for it. i hold that price does the same. i cannot write the matrix down. i am long the proposition that one exists, sized accordingly, and i will say plainly what that means: this is a conjecture i am funding, not a finding i am reporting.
