What's more, at 90(!!) years of age, he will present this monday a proof of the Riemann hypothesis, arguably the most important unsolved mathematical result of this time.

This is huge news, but many mathematicians are skeptical. Moreso because Atiyah claims the proof is "simple". Nevertheless, Atiyah wants to show math is not a young man's game only, and somebody of 90 can do something relevant.

Very exciting!
