When I started to write a completely new web-site, I failed to appreciate just how much work was involved. In fact, it is never ending because for every topic completed, two new topics pop up and need to be explored.
I had intended to get everything complete, proof read and perfectly formatted, but that is not to be.
When time permits, the Physicist level pages will be edited down to a level where someone studying maths and physics at High School or Sixth Form College will be able to understand them.
Until then, please accept my apologies.
