John Tukey:


"As I am sure almost every geophysicist
knows, distributions of actual errors
and fluctuations have much more straggling
extreme values than would correspond to
the magic bell-shaped distribution of
Gauss and Laplace."
                 




Alan Greenspan:


"Work that characterizes the distribution
of extreme events would be useful as well."
