A mental ice bath for anyone interested in solving real world problems and learning modern physics. Site also contains subjects in logical order on the side.
From the introduction:
‘This is a web site (under construction) for young students – and anyone else – who are (like me) thrilled by the challenges posed by real science, and who are – like me – determined to use their brains to discover new things about the physical world that we are living in. In short, it is for all those who decided to study theoretical physics, in their own time.’
