Ever been confused by all the letters and squiggles used by scientists?
Sixty Symbols is a collection of videos about physics and astronomy presented by experts from The University of Nottingham.
They aren't lessons or lectures - and this site has never tried to be an online reference book. The films are just fun chats with men and women who love their subject and know a lot about it!
Sometimes there's no symbol to tell a story (like Schrödinger's cat).
However whatever symbol you click on, I hope you'll see something interesting and maybe learn something new.
If there's a symbol you'd like explained, contact the creators at sixtysymbols@hotmail.co.uk
