Olly Britton

Hi! I’m Olly Britton. I’m an undergraduate currently studying mathematics and computer science at Christ Church, Oxford. This site contains a lot of things:

My notes on the courses I’ve taken as part of my degree so far, mostly in the form of around $10^{5}$ flashcards on different proofs, theorems, and the implications between them, for example:
- [[Notes - Logic MT24, Gödel’s completeness theorem]]^U
- [[Notes - Computational Complexity HT25, Nondeterminism]]^U
- [[Course - Complex Analysis MT23]]^U
- Currently working on: [[Part B]]^U
- For a list of everything and an explanation of my general note-taking process, see:
- [[University Notes]]^U
- [[A-Level Notes]]^A
Blog posts that I hope other people will find interesting, for example:
- [[FRACTRAN and theoretically cheating at your A-levels]]^B
- [[Extending multidimensional integration in SciPy]]^B
- [[Winning colourful Nim with the eeny-meeny rule]]^B
- For a list of all blog posts, see:
- [[Blog Posts]]^B
My notes from outside of university, where recently I’ve been learning about computational complexity, combinatorial game theory and American history, for example:
- [[Quantum Computing Since Democritus, Aaronson]]^N
- [[On Numbers and Games, Conway]]^N
- [[The Autobiography of Benjamin Franklin]]^N
- For a list of everything, see:
- [[Bookshelf]]^N
- [[Other Notes]]^N
…and other things I’ve shared:
- [[Favourite Media]]^M
- [[Projects]]^M
- For a list of everything, see:
- [[Misc]]^M

Many of the pages on here weren’t originally written for an audience, so for that reason they might be a bit confusing – this is especially true for my [[A-Level Notes]]^A. For some more info about how this website is made and how you can get around, take a look in [[About this website]]^B.

What’s with all the colourful links? These are wikilinks, and take you to the corresponding post with that title. The colour indicates the category: university notes, blog posts, personal notes, and misc.
