The good people at Revolution Books made me quite at home when I arrived, and the talk (see previous post for background) was fun. There were about 20 people there in the end, all very engaged and asking many excellent questions*. So I spilled over the allotted time as a result, but in a good way, since people really wanted more, it seemed. I managed to explain all the key parts of Special Relativity that I wanted to, unpacking in a way that seemed to work, and even went on to explain the Equivalence Principle and set up the key aspects of General Relativity.
The prep for the talk was a blast… I’d just written out some thoughts on several sheets of large drawing paper – the big stuff I like to do large life drawing studies on… 14 by 17 inches – including lots of the diagrams and short computations I use to build up the story… Then essentially I just showed those…. Or the key elements of the notes, by taking an ink pen and a stack of 11 by 8.5 printer paper and doing the key bits of each concept I needed an illustration for… That re-writing took a bit more than a couple of hours to do and then I photographed them, colour-corrected them, and dumped them into keynote, and from there to the iPad. All done and ready to go. I just showed the illustrations I needed while speaking from off the top of my head or checking my notes… Seemed to work rather nicely.
