I am a sophomore studying computer science and mathematics at Carnegie Mellon University. I am also a CS251 teaching assistant.

Abstract Algebra

I have written what (accidentally) became a small book on graduate-level abstract algebra. It is not meant to be thorough, it is just meant to give you an idea of the content you might encounter and a base of intuition.

Linear algebra

Formal logic and set theory

Euclidean geometry

I am writing a difficult honors high school geometry textbook, entitled A brief foray into Euclidean geometry. A preview of the third chapter is available.

Many references are broken; specifically, those to theorems/problems/etc of other chapters of the text. Additionally, hints and solutions still need to be written, and the chapter will occasionally be updated with new hints and solutions.

Miscellaneous mathematics

Puzzle StuCo

I am teaching a variant sudoku puzzle StuCo in the spring of 2024. Its course code is 98-049. If you have any interest in logic puzzles or learning about them I hope you consider taking the course.

Tentative details

Unlike the previous logic puzzle StuCo, my class will be entirely variant sudoku puzzles.

You can find the current course curriculum at its Git repository. All details stated there are tentative too.

Fun stuff
