Everyone loves a Zebra. But where do its stripes come from? A simple answer might be DNA; a more fanciful one that they’re painted on, like the leopard in Rudyard Kipling’s Just So Stories. In this lecture, Professor Sella takes us beyond the superficial, through complex and spectacular chemical reactions, and into the very fabric of our universe, where pattern and structure emerge as if by magic. Chaired by Dan Davis.
