How, exactly, does the Earth's tilt cause the seasons?
Different
individuals on the autism spectrum are impacted in different ways. The one area
in which I am severely impaired is spatial perception. I do not have good
intuition in this area and I have real difficulty reasoning myself through
spatial transformations. People will give me directions to a destination and
say "You can't miss it!" Unfortunately, my response is going to be
"Oh yes, I can!" Ever since I first learned about the Earth's tilt in
elementary school, I have been aware that Earth's seasons are somehow related
to the tilt of the Earth. Yet, until today, I have never been able to
understand how, in reality, the tilt brings about the change in seasons as the
Earth rotates around the sun. I have never doubted the truth of this
explanation and never suspected that there was some conspiracy going on to
mislead the population. I just didn't understand what was going on. I have
tried to read a number of descriptions and observed numerous animations. Until
today, I still ended up walking away without understanding the explanation.
However, after watching this lecture, I finally understand (sort of, at least):
