My proudest moment...
This would have to be waaay back in sixth grade, when I had just joined and literally knew nothing. Somehow, I made the State team for my school--and back then, it was pretty hard for sixth graders to make the competitive State team for the middle school. That year, I was in Physical Science Lab, and me, being the studier, had prepared for the test, and had only slapped a blade together the night before in about ten minutes. However, I had also studied the curves and shapes of PSL blades, and had figured out which ones worked best, and tried to cut it that way. Even so, we had to use materials that had already been used, all coated with glue and sawdust and other icky stuff.
Then at State, they canceled the PSL test, because there wasn't anyone to write it, apparently. Therefore, the entirety of our score depended on the performance of our blade. We went up there, tested it, and felt our hearts sink, because the spin of the blade was actually about 200-300 mV lower than usual.
We got second.
That was an absolutely amazing moment--my first medal at States, and the knowledge that had it performed up to par, there was a chance we could have gotten first. (They guy who got first was this amazing engineer/builder freshman from the junior high, who medalled gold in all of his events except for a single bronze in Shock Value.)
That is, without doubt, my proudest moment.
EDIT: Fixing some grammar
Physics is difficult for 99% of the world's population because they don't understand it. The other 1% know too much.
