R in particular is fascinated by it. It is all very freaky. How on earth do things change depending on what they are being measured for?! And how is it that if things crash together you get two things? And how come if you do get two things, where, if all of everything is made from the same bunch of stuff, did it take the stuff from to become two. These are all her questions! There is a beautiful bunch of books by Jennifer Morgan and Dana Anderson that go some way to explaining to a small child (and ignorant parent) scientific creation theory with a real sense of spirituality . thanks Bob, will look out that book. many many many conversations here are revolving around quantum physics at the moment.

All seems like big words to me, think I've been put off because all the geeky boys did it at school (me of course being oh so not geeky!!!). I know nothing about physics, but wish I did.

(Anything other than hydrogen only exists because of the nuclear fusion reactions going on inside stars building up bigger atoms like carbon, which only get out when the star explodes at the end of its life.) Also, the fact that even a vacuum isn't actually empty, but full of pairs of virtual particles that pop out of nothing (a kind of temporary loan of matter and energy from the universe), whizz around for a bit then collide and annihilate each other (thereby paying off the loan). Virtual particles + black holes (!) means that one of the pair could fall into the black hole while the other doesn't, so the survivor hangs around rather than being annihilated by its evil twin, which means that black holes actually radiate particles. Particle / wave duality, quantum superposition and so on - very freaky! I know enough to be dangerous but not enough to be useful ;-). I recommend a book called <a href="http://astore.amazon.co.uk/scientific-21/detail/0387914951" rel="nofollow">Alice in Quantumland</a> Absolutely Em, for instance the fact that we’re all made of star dust.

Its far more magical to me now, finding stuff out with the girls, than it was at school. We have had so many philosophical and somewhat mystical conversations surrounding physics and quantum physics...how stuff can come from no where, how everything is made of everything, and how its all linked together, black holes, and explosions in space...amazing place we're a part of :) Physics is most definitely still magical here.
