| Paradox: rapidly slowed charge emits more radiation energy than it had in kinetic energy | 05 Jun 2004 00:38 GMT | 12 |
Here's the problem: When a charge changes velocity, its electric field is
"kinked" by the causal delay moving out at c. This radiative field has energy
(even if not periodic), and the Larmor formula for power is: P = (2/3)kq^2 a^2
/c^3. Take a charge q at v, and decelerate it to a ...

I was recently given a chart of wireless signals running throughout a
major city -- cellphone, radio, tv, wireless internet, whatever. It
was suggested that the shere volume of these signals which number in
the hundreds of thousands in small condensed areas is hazardous to
