John Nash has died. The NYT says:

Dr. Nash was widely regarded as one of the great mathematicians of the 20th century, known for the originality of his thinking and for his fearlessness in wrestling down problems so difficult few others dared tackle them. A one-sentence letter written in support of his application to Princeton’s doctoral program in math said simply, “This man is a genius.”

Well, thank God he got through before the current tick-boxing charade crippled much of higher ed and the NHS.
