The Periodic Table in Chinese – each element is just one character, which includes radicals that tell you if the element is a metal 釒,  a gas 气 , a liquid 水or a non-metal solid 石.   This video could help you write and pronounce them.

We Needham to know this!

I  just listened to a good 2-part summary of the work of Joseph Needham from the China History Podcast: part 1, part 2.
His mammoth book describes the many scientific and engineering achievements of China, from the four great inventions to the stirrup!

I had not realised that he was instrumental in founding the Society for Anglo-Chinese Understanding : the SACU website has interesting articles and videos.
I am now keen to read more, such as Bomb, Book and Compass (know as the The Man Who Loved China in USA)by Simon Winchester (I enjoyed The Surgeon of Crowthorne years ago).  Not sure if I will manage all the volumes of Science and Civilization in China!

There are several interviews with Simon Winchester on the internet.
