This is a collection of articles about interesting physics you may not have seen in your A-level education or have, but have not seen the mathematics behind it. These topics may also be good starting points for a personal project or an EPQ if you choose to do one. An EPQ (Extended Project Qualification) is an optional qualification taken by students studying A levels and is equivalent to an AS level. On each post we will provide references for you to do extra reading if you wish to find out more!
