Jierui Lin
Hi all! I am a third-year CS & Applied Math major. I just took CS 170 last semester, so I have a pretty fresh memory of the course material. To me, this course is like an art appreciation of the most brilliant minds in the history of CS & Math. I’m sure you’ll learn a lot from this. In my free time, I enjoy watching movies, listening to music and playing soccer. Feel free to chat with me about anything!

Nate Young
I'm Nate. I'm a 3rd year EECS major. My best quality is that I own a cotton candy machine and in my free time I try to do theoretical CS research, think about machine learning, and sleep. And just waste an embarrassing amount of time. 170 is the best class. Handwavy math philosophy is the best type of philosophy.
