The 2018 Physics Prize Problem is out! The Porter Prize is funded by Carroll Porter ’32, and is awarded annually for the best solution to a complex physical problem. This year’s mind-boggling physics problem concerns a planetary interloper scattering from an originally stable solar system. Check out a detailed statement of the problem, posted around SMC or available at http://course.knox.edu/physics130. Any Knox student may submit a solution. Turn in your solution to Prof. Tom Moses, D110 SMC, by 4 p.m. on Tuesday, May 1 and win a place in Knox history (and a cash prize).
