Revelation

Browsing through the local branch of Waterstones I came upon an intriguing volume called 'Quantum Mechanics The Theoretical Minimum'. Following a reference in that book I discovered a website with a series of lectures on theoretical Physics with various supporting materials.

The object is to explain basic physical ideas as simply as possible, avoiding both the superficiality of the popular books that avoid Mathematics and therefore explain very little, and the obscurity of the texts that use quite abstruse mathematics without making any serious attempt to explain what they are doing. What I have read so far seems to be quite a good attempt. Two things that had been puzzling me are now clear, and I look forward to more enlightenment.
