I will be a math PhD student at UC Berkeley this fall.

I have been a math major at Cornell University 2016-2020. I was also an officer of the Cornell Undergraduate Math Club and a tutor at the Math Support Center.

Here are some presentations and lecture notes.
I'm compiling my solutions to the textbooks I'm reading. All comments welcome!
SP18-SP20: I wrote puzzle sheets for the math club meetings. Among those, problems I wrote may or may not have a known solution; I'm happy to discuss them.

For Spring 2020, I did a reading course on classical geometries. I wrote a viewing distance calculator for that class. It was supposed to be intuitive, but I have yet to write instructions for it.
For Fall 2019, I am a grader of Math 1105, Finite Mathematics for the Life and Social Sciences. I posted some fun problems for that class.
Ross Program. A summer math program for high school students. I returned as a junior counselor in 2016 and as a counselor in 2017 and 2020. I also worked at PROMYS in 2019. This is a program started by Ross alumni with similar content for first year students but with a somewhat different flavor.
I translated some LaTeX tutorial slides (English to zh-cn; Part 1 | Part2 | Part3).
I make mathy t-shirt designs occasionally. You can find the shirts here.
Writing and styling this website. Feel free to use its (very incomplete) style sheet! Also, W3Schools is a great reference.
>> You can copy the following line to your header: <link rel="stylesheet" href="https://math.cornell.edu/~tanjz/sty.css">
>> Not working? You also need to add class="lightstyle" to the start tag <body>.
Mersenne.org. A distributed computing project to find large primes. If your computer looks bored, you can volunteer its power.
