[Offtopic] Physics in the UK

Wow, what a horror story Cameron. The writer sums it up quite nicely as
melting pot filled with the vague, the stupid and the unscientific. It is
almost as if journalism has taken over the teaching of science.

Next thing, we can expect the mystery of crop rings taking over from the
delicious world of quantum events and particles.

Heisenberg's cat now has a reason to be nervous.

> To get the mark, pupils must answer:
> More UV absorbed by dark skin (more melanin)

> There is a teacher shortage in this country, but if a physicist asked

> unless you want to watch a subject you love dismantled.
> I am a young and once-enthusiastic physics teacher. I despair at what
> I am forced to teach. I have potentially thirty years of lessons to
