Welcome to Lecture Notes

The number of universities publishing complete sets of video lectures online is growing rapidly. Of most interest to me are courses on physics, and in particular, two sets of courses given by renowned physicists, Professor Leonard Susskind and Professor Walter Lewin.

Over time, I intend to add my own set of notes on all of these lectures and hope they may be of use to fellow students as a reference. But, of course, watch the videos first!

Here are some examples of MathJax in action:

Javascript is currently disabled on your browser. All of the mathematical statements on the site will display as raw latex.

The downside is some of the pages take time to process. A box appears on the bottom left of the screen which displays the progress - you'll have to wait for this to disappear before you can scroll down the page.

I also use a beautiful java applet called Geogebra to draw most of the diagrams on this site.

Geogebra is free dynamic mathematics software that joins together geometry, algebra, tables, graphing, statistics and calculus. It allows for both quantitative and qualitative diagrams.

I also occasionally include Geogebra applets themselves, which should run successfully on most computers, since java is often already installed, but you might need to get the latest update.


This website has no connection or affiliation to any of the institutions or lecturers mentioned.

This is one non-physicist's set of organised notes which, hopefully, may be of some use to others. Any errors in my notes are mine alone and readers should beware that they might not reflect the content of the lectures accurately.

I would very much appreciate all and any corrections, especially on any of the physics or mathematics, but I'm sure there's the odd typo or two!
