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!

It's worth noting many symbols have multiple uses across scientific disciplines and we somtimes tackle them from an unexpected viewpoint.

Click on "gamma" and you'll find a professor of physics talking about cricket balls... Click on "rho" and we're stuffing paperclips into coffee cups.

And sometimes when there's no symbol to tell a story (like Schrödinger's cat), well we just make one up!

Whatever symbol you click on, we hope you'll see something interesting and maybe learn something new.

Or if there's a symbol you'd like explained, contact us at sixtysymbols@hotmail.co.uk

We've also got a great site about chemistry at www.periodicvideos.com

Or go behind the scenes with scientists at our other site www.test-tube.org.uk

Thanks for visiting.

PS: You may have noted more than sixty symbols on our homepage. That's because when we finished, everyone asked for more. We're currently working on the second sixty!
