Here is the math page for Chengyang Wu.
One quotation for this era:
Between midnight and dawn, when sleep will not come and all the old wounds begin to ache, I often have a nightmare vision of a future world in which there are billions of people, all numbered and registered, with not a gleam of genius anywhere, not an original mind, a rich personality, on the whole packed globe. The twin ideals of our time, organisation and quantity, will have won forever. – J. B. Priestley
