I'm a college student in the states studying Mechanical Engineering and Physics. During the day, I do research in a lab, take classes, and work as tutor on campus. At night, I play with matlab, read books on complex analysis or mechanics, sometimes I play board games with friends, other times I show them this stuff. On the weekends during the day, I climb fake rocks and video chat with friends on interesting topics we've individually learned and try to get each other to understand in hopes that we as an instructor give it enough thought to figure it out ourselves, it goes about as well as it sounds.
