I am still blown away by the sheer amount of luck in getting a beam of silver atoms to split. Even now close to 100 years after it seems something that if you made a movie of it no one would ever believe. MP4 recording     MP3 recording -- -- Your browser does not support the audio element.

Reading an indepth article about "Two new Sciences" by Galileo and his scaling theory played out in a very renaisance life. MP4 recording     MP3 recording -- -- Your browser does not support the audio element.

I now know what things look like because of some group theory and quantum mechanics, but it is spooky and essentially magic. MP4 recording     MP3 recording -- -- Your browser does not support the audio element.

Sorry fans of the classics the storyline is a kind of Games of Thrones meet toy story. I explain it by recounting it in sequence with absolutely no surprises and everything absolutely spoiled. He goes down 9 floors all because of a girl called Beatrice, and faces his own past as a unfaithful war criminal. I think Emily Rodda wrote better stuff with DELTORA quest. I just cant forgive the bottom of the inferno being a deep freeze. It was a bit like a Circus act I saw in Penrith years ago, called the Deathdefying Dome of Death. We now know why there were no Australians in the Renaisance because they wouldn't shut up and go along with all the deals.

Galileo had troubles with his roof of hell being too thin on a global scale, in an age of admitting a mistake was certain acedemic death. Hope this is helpful to Prof Dave. MP4 recording     MP3 recording -- -- Your browser does not support the audio element.

Its mostly terminology and common sense so for. Left and Right cosets of a group forming their own group. Homologous groups relationships seams pretty powerful as if you can do a bit of work showing some similarity in some area you can then apply your insight into a new field. It seems to be tracking into the big insight as to why Nature symmetry are the locking in the topology of particles and space. It turns out I only printed half the article so we have stopped before it gets mind bendingly hard. I recommend having the article there to read through it. I now know what S stands for "special", U for "unitary", O for "orthagonal". But to be honest I really only understand well orthagonal because all electron wavefunctions are orthagonal. I am now remembering what the script letters X, R, and C stand for natural, real and complex numbers. id stands for the identiy operatior which is 0 for addition and 1 for multiplication. I understand that middot and + stand for non and commutivative operation. And the associativity means you can work through a queue of operators as long as you dont change the ordering in the queue. Oh well, people have never given me a clear self consistent explanation why one shouldn't understand this stuff.

Protons are not hard spheres rather they are full of gluon juice that jets out when it is slamed with an electron in an accelerator. MP4 recording     MP3 recording -- -- Your browser does not support the audio element.

With Photons and Gluons being Gauge Boson it is time to find out what Gauge theory is and how it applies to the Standard model of the Universe MP4 recording     MP3 recording -- -- Your browser does not support the audio element.

These are masses photons of the proton, but they have charge (red, green, blue) and are prisoner. So going back and carefully reading the Wikipedia article that you will here, I have removed some errors in my thinking. I now know that gluons do not stick, the nucleus together that is the job of mesons. Gluon have the same colour as quarks by are unrelated to them, they are only the colour vibration inside the strong force. I now have to study gauge symmetry.

I was really touched by care for his first wife. I find it defies thinking to think US univerisities put Jew quotas on their intake. The chilling fact was he did crack the safes inside the Manhattan project and was friends with a Soviet spy. It was really good to hear his analysis of his year in Brazil. His analysis of human to human transmision of knowledge going fatally wrong without experiment quality control is just great. The insight he had into the NASA upper management being disconnected gives pause for thought. His Feyman diagrams is one of the great contributions to our civilization.
