    They're called string theories because the equations that describe particiles are similar to the equations that describe occilations in strings.

    Very briefly, the strings vibrate, and it's the vibrations that generate particles. Not the strings themselves but the way they vibrate. The vibrations are quantized - grouped in levels like the energy levels of electrons in atoms, and for example the graviton comes from combining two sets of vibrations at the second level. (In bosonic string theory with closed strings).

    3 definitions that need a lot of work to make theoretical physics mentally tangible...
