Start of education: First weekly summary

What I learnt this week

As I have started my studies officially this week, I have decided to do a quick summary each week for what I have learnt. I will still be attempting to publish my own study notes as well. I will also be uploading a log in which I will update what I have done outside of my timetable every week.
