Re: Noted scientists
Why does there have to be *any* person on a banknote?
I expect Hawking will get it, and he is indeed a deserving candidate. Not to mention preferable to those candidates whose merits - though worthy - are secondary to matters of identity politics.
I shall make myself a lonely outlier by suggesting G H Hardy. His Mathematician's Apology was a seminal influence in my life, both for the way it shows the beauty of maths, and for its setting in the lost world of the academic elite it portrays. Deeply unfashionable of course, and his championing of Ramanujan probably just makes it worse, as that was purely on merit.
 It was one of main things that influenced me to study (pure) maths at Cambridge.
