Another Nobel for MIT 

MIT physics professor Frank Wilczeck, David Gross and David Politzer have been awarded the
2004 Nobel Prize in Physics for their work on the strong force (the force that holds quarks together to form protons, neutrons and other interesting creatures).

According to quantum field theory, the fundamental forces of nature are mediated by exchange particles. The electromagnetic force arises from the exchange of virtual photons between charged elementary particles. (These virtual photons sometimes turn into real photons, i.e. light.) The weak force is mediated by W and Z particles.

What are the exchange particles for the strong force called? Gluons. No kidding.
