I like physics

I'm teaching cosmology at the moment (though not to this level). It's nice when one gets a happy coincidence as to how science proceeds. Go Einstein:

General relativity survives gruelling pulsar test -- Einstein at least 99.95 percent right from

An international research team led by Prof. Michael Kramer of the University of Manchester's Jodrell Bank Observatory, UK, has used three years of observations of the "double pulsar", a unique pair of natural stellar clocks which they discovered in 2003, to prove that Einstein's theory of general relativity - the theory of gravity that displaced Newton's - is correct to within a staggering 0.05%. Their results are published on the14th September in the journal Science and are based on measurements of an effect called the Shapiro Delay.


Go read the whole thing, but don't worry if you don't get it, most people don't.
