From the Sixty Symbols Introduction page:
Ever been confused by all the letters and squiggles used by scientists?
Hopefully this site will unravel some of those mysteries.
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!
I don’t know about you, but I am going to enjoy watching these videos. Click here to view the fascinating and easily-understood scientific talks they have there.
