It was sad to see him die of throat cancer. His profound religious belief explains a bit of his relationship with Faraday. I am really into quaternions and now see how he approached Electromagnetic Radiation. I like the way his colour photography experiment was in fact a fluke as the red dye was UV sensitive.

Talking through the equations. There is not much to them with straight and circulating fields. MP4 recording     MP3 recording -- -- Your browser does not support the audio element.

You can forget teaching the Bohr liquid drop model with cute little spheres. I will eventually get this explanation out there. MP4 recording     MP3 recording -- -- Your browser does not support the audio element.

They are Big-Big. Big, Normal, Small That is trillion trillion to one, trillion to one, one to one, and one to trillion. What strikes me is that in the Big scale the Sun is a 1mm ish ball bearing while the Small scale its a proton. I am trying to get my head around my own brain trauma that means I continually forget and rework this basic stuff and filter out just not your own mistakes but widely held mistakes. Its not really something other can understand, so I am left trying to describe it. Oh well! MP4 recording     MP3 recording -- -- Your browser does not support the audio element.

It's actually amazing to hear or read someone who is far more articulate that you will ever be. Because I am keenly aware of little Aussie Trumps that have been popping up here all the time I am think it is really to simplistic to be judgemental, I just feel great empathy MP4 recording     MP3 recording -- -- Your browser does not support the audio element.

I will put up the Chinese checker boards of neutrons protons and other particles to get one mind around the Zoo of particles you get when you excite the bags of colourful quarks. MP4 recording     MP3 recording -- -- Your browser does not support the audio element.

This is my best effort at explaining the zoo of particles you get when you start with the up, down and strange quarks. I have some insight to what these guys are up to and what maths go where. The symmetry and group theory maths guide you through the equations but don't give you an mechanism. It is my first effort in this field MP4 recording     MP3 recording -- -- Your browser does not support the audio element.

Really interesting to see how the scientists are tackling this one. So good we have sequencing technology MP4 recording     MP3 recording -- -- Your browser does not support the audio element.
