I find the last paragraph of the section on Stored Energy to be a bit misleading. The fact is that two oppositely charged particles held in close proximity will have less energy than two oppositely charge particles held infinitely far apart. However, both energies are formally infinite for point particles. This has nothing to do with quantum mechanics. Defining a single charged point particle to have zero energy is the quantum mechanics, and is a good introduction to the idea of renormalization. If such a paragraph were included, it would be nice to point out such subtleties, rather than cloud matters by saying the previous equation isn't true. |

Negative Stored Energy in QM?
I find the last paragraph of the section on Stored Energy to be a bit misleading. The fact is that two oppositely charged particles held in close proximity will have less energy than two oppositely charge particles held infinitely far apart. However, both energies are formally infinite for point particles. This has nothing to do with quantum mechanics. Defining a single charged point particle to have zero energy is the quantum mechanics, and is a good introduction to the idea of renormalization. If such a paragraph were included, it would be nice to point out such subtleties, rather than cloud matters by saying the previous equation isn't true. 70.253.79.237 (talk) 18:19, 8 February 2009 (UTC)
