How modern mathematics emerged from a lost Islamic library

Awesome! Now added BBC Science to my home screen.

This was a fun read -- thank-you

PO1 Tony Holland Excellent share.
"The House of Wisdom was destroyed in the Mongol Siege of Baghdad in 1258"
Destruction of Libraries (a university actually) is perhaps as bad or worse in some ways than a scorched earth policy. The Library at Alexandria was destroyed several times too. It's no wonder people are driven to disperse valuable knowledge so that it becomes common knowledge to be built on and improved, over time.
