I assume by "third square root" that you mean cube root?  To me, third
square root would mean sqrt(sqrt(sqrt(8))).

I think you'd want something like 8.root(3), not 8.sqrt(3).   Square
root has a very precise meaning.

Also beware, 1/2 == 0 because of integer math.

The article does raise some interesting questions, but certainly lends
itself no credibility due to the presentation.  And I'm certainly not
going to become a 'Pythonista' due to this kids rant.  You can easily
pick a few elements of any language and pick on them to your hearts
content, but it really just comes down to getting things done, and
Ruby does that for me.
