Must admit - I only know the 'basics' of physics as found it a bit dry (sorry) and concentrated on biology and chemistry up to degree level.
I say this not in an attempt at humility (though being British is hard to fight off the urge - and queuing - we are ALL about the queuing)
But to point out that I don't comment as I am not au fait enough with the subject.
Can you see the point I am making here ?
Something about biscuits and tea, right?
