Over the course of my studies, I have amassed a large quantity of notes and summaries. Over time, I will try to upload as many as possible – it’d be nice if they were all in one place.

**Cambridge Natural Sciences****Online courses****Notes on academic papers****Textbook notes**- QED: The Strange Theory – Richard Feynman
- The Feynman Lectures on Physics – Richard Feynman
- Why Chemical Reactions Happen – Keeler and Wothers
- Introduction to Statistical Learning – James, Witten, Hastie, Tibshirani
- Elements of Statistical learning – Hastie, Tibshirani, Friedman
- Advances in Financial Machine Learning – Marcos Lopez de Prado

**Miscellaneous notes****International Baccalaureate (IB) notes****IGCSE (Cambridge 2013 syllabus) notes**

A few years ago I read ‘Surely You’re Joking, Mr Feynman’, and since then fell in love with Feynman’s style of teaching physics. ‘QED: A Strange Theory’ is a semi-technical book in which Feynman discusses the physics substantively rather than just talking about physics as a discipline. Just to clarify, I have no complaint whatsoever with him talking about physics from a more ‘meta’ point of view, as was done in ‘The Character of Physical Law’. I read the book, and loved it. He doesn’t sacrifice any of his characteristic charm, while still explaining the counterintuitive theory. This book was transcribed from a series of lectures (available on youtube), so is naturally quite verbose.

So far I’ve only done a few chapters of volume 1. I really intended to work through it in its totality at one stage, but I realised that I should use my time before university to learn things other than physics.

Link: Why Chemical Reactions Happen (notes)

In January 2015, when I was examining the reading lists for Cambridge and reading example personal statements for Natural Sciences, I noticed that a common denominator was the book *Why Chemical Reactions Happen*, by Keeler and Wothers. I proceeded to read the first two chapters, and was able to easily follow the physics-based reasoning. I therefore listed it on my UCAS personal statement, with the full intention of reading the whole thing before the interview. However, after the first few chapters, the material becomes rather dense (especially with the focus on MO theory). I did endure through it, and made some notes along the way. The notes are quite verbose, because the book itself is quite succinct anyway. I wasn’t asked anything about the book in my interview, which I suppose is fortunate because I would have probably struggled.

Link: Notes on the Binomial Theorem

An acquaintance of mine was once having trouble wrapping their head around the Binomial Theorem. As someone who likes maths (and likes teaching people maths), I wanted to come up with an intuitive explanation.

Link: Notes on CT1 Financial Mathematics

Because I was considering a career as an actuary, I thought it might be interesting to take one of the exams to get a better understanding of the material. Following the ‘study plan’ from the Institute and Faculty of Actuaries, I was torn between CT1 (financial maths) and CT3 (statistics). I decided to choose CT1, because I was already confident with the CT3 content, so I thought that I would learn more from studying CT1.

These notes were made following the free Warwick notes, which were a sufficient guide for the exams in my opinion.

Link: Introduction to Boosted trees.

As I have mentioned elsewhere, for a period I became very interested in gradient tree boosting, particularly XGBoost – a review can be found in this post. One of the best expositions of XGBoost was some informal slides, made by its creator, Tianqi Chen. I think it’s well worth a little bit of effort to understand XGBoost, because it is a very powerful algorithm.

Link: CUFIS Valuation Workshop

In January 2021, I gave a workshop on Investment Valuation to the Cambridge University student investment fund.
