Code++ is a club dedicated to learning advanced computer science topics. In the 2025-2026 school year, I serve the role of Vice-President within the club.
An introductory lecture to Turing Machines and the Busy Beaver problem.
An introductory lecture to the problem of \(\mathsf{P} \overset{?}{=} \mathsf{NP}\). The lecture is quite advanced, however.
This presentation was originally made in 12/25/2025, but due to scheduling conflicts it had to be pushed back several months.

Standard lecture about time complexity formally (including details about \(\Omega\) and \(\Theta\)).
This was a guest lecture for the Code++ club and centered around a friendly introduction into \(\lambda\)-calculus.
Here are some lectures that may be scrapped.
The following is an incomplete lecture about logic and proofs. I decided to include it because it is partly complete (the entire proof section is), and it is possible that it will be scrapped.
