Well, I saw your contribution list...has your university closed down or have you left your girl-friend or what? Do you sleep at night...just for a change? 

No, seriously, how much was your Science & Civilisation compendium and where did you buy it? And how many volumes? 

PS: Do me a favour and do not make Aunt Wiki a branch office of Needham's. His book is already a bit dated (partly 40-50 years), and to be honest, I have my issues with his unremeediable scientism, diffusionism and partial views. Why don't you take more recent reserach from the new - and less prone to scientism - generation of sinologists. ;-) Regards
