The train of thought that culminated in this project set off when my good friend (Rish) sent me a list compiled by the New York Times of the “100 Best Movies of the 21st Century”. Scrolling through the list idle mindedly, I picked out the films which I’d seen, silently agreeing with the list for including them. However, when given more thought, I started to wonder the methodology behind this ranking.

Figure 1: Example Binary Tree
For a fixed \(p\), independently label the nodes of an infinite complete binary tree \(0\) with probability \(p\), and \(1\) otherwise. For what \(p\) is there exactly a \(1/2\) probability that there exists an infinite path down the tree that sums to at most \(1\) (that is, all nodes visited, with the possible exception of one, will be labeled \(0\)). Find this value of \(p\) accurate to ten decimal places.

Figure 1: Graph view of my notes so far
I’ve recently started working on my master’s thesis, and as such I’ve been looking for a good way to take notes. I need to be able to capture notes on my reading, as well as any ideas or thoughts that I have. I’ve previously experimented with:
Notion - I did like how feature rich it was, but I disliked the rigid organisation structure. I felt forced to organise everything into a heirarchical pages and sub-pages. Also, it felt like once I committed to Notion, it wouldn’t be possible to switch platforms if I wanted to.
