What, you believe everything you were taught in grade school?
Imagine if the Earth were a ball, and the sun were a torch shining upon it. Now imagine, if you will, that you would like to adjust the axis of rotation of the ball to the devil's number - 66.6degrees, or 23.4degrees, if you measure the opposite way. Now, you will realise, if you rotate the ball along it's pupportedly-coincidental evil-seeming angle, or indeed, any other angle, that no matter where on the ball you measure, with the exception of the poles, the light is incumbant on the ball exactly for half a revolution. That would equate to 12 hours on a 24 hour day, irrespective of the lattitude selected.
Does the education in North America extend beyond the indoctrination presumably delivered during grade school?

"only at the poles" ??
i learned something called 'the mean value theorem' in calculus.
it's pretty straight forward:
for any continuous curve that has value A at one point and B at another, at some point between those two it has value equal to half of (A+B).
i'm just going to leave it at that and see if you're as clever as you insinuate.
