========== Molecules! So many of them in their infinite
and beautiful variety, but while that variety is great, it can also
be pretty dang overwhelming. And so, in order to help this complicated chemical world make a little more sense, we classify and we categorize. It's our nature as humans, and it's extremely
useful. One of the most important of those classifications
is whether a molecule is polar or non-polar. It's a kind of symmetry, not just of the molecule,
but of the charge. It's pretty easy to see when you're just lookin'
at 'em. You got polar and non-polar, polar, non-polar,
polar, non-polar. I'm gonna take sides right now.
I'm on team polar. I think polar molecules are way more interesting,
despite their wonky, off-balance selves. Non-polar molecules are useful, and their
symmetry has a kind of beauty,...
