To get significant numbers of events, experimentalists need huge amount of matterials such as tons of water as collision target. here's a picture http://cerncourier.com/main/article/40/6/18/1/cernbegin4_7-00 Neutrino masses and neutrino oscillations are hot topics that can result in nobel prize awarded research. As a good TA, I don't kill. One tip for you: no matter how messy your pages are, write the results correctly, clearly and in a box.

The list seems awesome, but wait, you definitely need some "Dancing club" or "Franch" or whatever classes where you can meet chicks. good luck ~ Courses that may be related to goemetries are

1 MATH 1300 Vector Geometry and Linear Algebra 3

3 MATH 3230 Metric Spaces 3
