Well, it's depends... Thunder storm? Calculation? Well, if we begin to think
that thinking is just kind of comparison, we may say that's it's just
something like calculation, but we have to keep the idea that's a chemical
comparison, which includes molecules, atoms and eletrical interactions
between them... That would be classified as a thunder storm...
I can't tell what really is the "thinking mechanism"(unless i were a
genius:-) but i figure out that it envolves many things... It's like a game:
when you memorize something our brain(not only our brain: i'd say our
nerves) is able to make a specific molecule. The specificity and the
stability of this molecule will tell us how long will "take" this memory...
