Spieglein, Spieglein, An Der Wand...
I'm going to stick roughly to the theme of the last couple of posts here tonight, in that I was reading Carlo Rovelli's seminal 'Seven Brief Lessons on Physics' this lunchtime, over a couple of pints of local beer and a poke of chips, at the Bull in Biwmaris [Beaumaris]; specifically his second lesson, 'Quanta', which aims to enlighten the casual reader to the niceties of Quantum Theory/Mechanics in layman's language. As always, like all good teachers, he lays out the complex in terms that most of us can at least grasp, leaving the technical and mathematical underpinning to one side in order to give a clearer overview of frankly, apparently, mind-boggling concepts. On the question of the un-resolvability of the exact existence of electrons [Heisenberg's theory], or their position in space when their interactions reveal them to us, he has this to say: '... an electron is a set of jumps from one interaction to another. When nothing disturbs it, it is ...
