stings per electron

[Pjpic]

Does the theory say that an electron is a single vibrating string? How many parameters are needed to describe that string? Does the theory say how long the string is?

In string theory, the electron is a single vibrating string. The length of the string is roughly the Planck length, or 10-35 m. The only parameter of the free string is its tension, which is related to its length.
