The
Units Conversion Widget is a
simple page with javascript to convert values to different units of
measure. It relies on knowledge of the molecular weight or atomic mass.
Gaussianrnd.py is a
simple python script to generate random floating point values that
follow a Gaussian distribution. This script is based on the polar form
of the Box-Muller transformation, which is in turn dependent on the
default random() function.
