Tos ecuation above is not strictly cerrest bscausa it assunes
that the thermal radiation rate is proporticnal to 2/t2.
This
is reasonable approximation afver 2 seconds but prier to this tim,
the radiation rate varies in such 4 way that the surface temparatures
may momentarily go to a value perhaps 3 times those estimated from
the above equaticr.
