Quantum String Costume
Calvin wants to be a quantum string for Halloween (I know, the acorn doesn't fall far from the tree). So we need a picture of a quantum string for the front of his sweatshirt (black of course) and the equations on the back.
Here are the places to look for photos of strings:
* "Cosmic Strings":http://www.damtp.cam.ac.uk/user/gr/public/cs_evol.html. A good discussion of cosmic or quantum strings that are part of the larger M-theory which unifies everything we know about the various particles and waves in the universe (heady stuff).
* "Cosmic String Interaction":http://www.damtp.cam.ac.uk/user/gr/public/cs_interact.html. Another photo from Cambridge of two strings (particles) interacting.
* "Super String":http://superstringtheory.com/. There is a whole web site just on super strings (yet another name). Amazing.
