Sixty Symbols - Physics and Astronomy

Sixty Symbols Menu


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 by experts from The University of Nottingham.

Vacuum and Pascals Neutrinos Quarks Spiral Galaxies and Pattern Speed Planck Length Faster than light Alpha Beta Gamma The Fab Four Saturn Feigenbaum Constant Pi

It's worth noting many symbols have multiple uses 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 - well, we just make one up!

Whatever symbol you choose, we hope you'll find something interesting and curious.

Or if there's a symbol you'd like explained, contact us at

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!
