A mathematically trained ex-psychologist says that 10^40 is
2^132, more or less.  a^x = b^((x*log(a))/log(b)) - in this case
10^40 = 2^(40*1/.303) = 2^132 to three place precision.

I think correcting an error of over 20 orders of magnitude (200*.303 -40)
is not nitpicking, wouldn't you agree?

Isn't it interesting how the beautiful little red flower in the forest
becomes so ugly when you discover it's a candy wrapper.
