Step One: Break the tele Of course you could just shoot it Then we looked at the working of the Cathode Ray Tube in a little more detail: The cool thing about is that it enables us to look at the wave nature of the electron. Given that this (Quantum Theory) is one of the [...]

I have a new microphone so tried it out on one of my favourite excerpts from Bill Bryson’s ‘A Short History of Almost Everything’. 15 minutes long, it contains some wonderful nuggets on this all-important but surprisingly unreactive set of molecules. more about “Vodpod Firefox Extension for WordPress“, posted with vodpod
