Clementine oranges are the perfect study food for the following reasons:
1. I never get enough vegetables/fruits in my meals
2. don't have to wash them
3. no seeds
4. not too large, not too small
5. really, really sweet and juicy!!!

I realize why I like math so much more than any other science. It's so easy in physics, to handwave, for example, for someone to explain something you don't understand by saying "It's due to this other xxxx force (which you have never heard of) that you need to account for." or just as easily, "In this case, the xxxx force is negligeable enough to not be accounted for." In math, there is no such handwaving: what is there is there, and it all makes perfect sense. Or some sense. Or at least more sense than everything else I'm doing.
