I’m a math grad student at Mass Tech under Wei Zhang, and also a math olympiad coach, volunteer, and YouTuber on the side. In the boring real world, my research interests are in number theory and combinatorics. You can download my CV, see my publications and research, or read my university transcript. Outside of math, I hate cooking. I am on GitHub, Instagram, Twitch, and WordPress. You can also see my personal page for trivia about myself. Fellow Linux geeks can download my GPG key from ubuntu, opengpg, MIT, or GitHub. If you are a high school student interested in math olympiads, you may visit the beginner’s page, my collection of handouts, or my archive of past problems and solutions. -------------------------------------------------------------------------------- The nine-point circle of $\triangle BIC$ is orthogonal to the circle with diameter $ST$.
