statistics, are my calculations correct?  PsyDAG, Saturday, October 23, 2010 at 8:43pm
a) If length is continuous, wouldn't time also be continuous?
b) The fractions can get smaller and smaller (e.g., 1 and 1*10^9)
Otherwise, I think you are correct.
For your own safety, it is better not to use your whole name.
