It's interesting from recent posts on Dr Woit's weblog, to see that people attack a clearly expressed idea which uses widely familiar physics algebra - capable of being understood by everyone - as simply not being sophisticated. Unfortunately, I see that Dr Woit has now deleted both Dr Chris Oakley's daft comment and my humorous reply!
Let's apply his argument to Newton's Principia of 1687, which expressed gravity using Euclid style geometry which had been developed in 300 BC.
Because Newton does not use calculus, Dr Oakley would presume - I guess if he is consistent - that this fact 'proves' Newton was ignorant of calculus and was a crackpot for using geometry. Whoops! Newton was actually one of the developers of calculus!
What you have to do when you have a radical development is to maximise understanding by expressing it with the most familiar means possible.
