Hi, while that web site is related, or about a presentation, I guess, here is his own web site where you can read the book:

well it is Xmas ... here is an interesting book I found from a given for some good holiday reading ... http://books.google.com/books?id=WwK...age&q=&f=false

I was curious as to how the measurement of temperature was arrived at. The answer is:
'Inferred' is not a physical measurement is it? This is a presumption based on a mathematical concept?Scientists measure the temperature of hot matter by looking at the color, or energy distribution, of light emitted from it -- similar to the way one can tell that an iron rod is hot by looking at its glow. Because light interacts very little with the hot liquid produced at RHIC, it bears accurate witness to the early cauldron-like conditions created within.
Said Vigdor, "The temperature inferred from these new measurements at RHIC is considerably higher than the long-established maximum possible temperature attainable without the liberation of quarks and gluons from their normal confinement inside individual protons and neutrons. "However," he added, "the quarks and gluons in the matter we see at RHIC behave much more cooperatively than the independent particles initially predicted for QGP."
Interesting article.
So many paths to the same destination,
would, but I could, experience them all...
Not exactly ..... temperature is a 'macro' description for motion. There is no such thing as temp, only motion with 'quantised' jumps in energy ? The 'energy' of light can be measured in this way ... and the temp is inferred from these measurements.

hope this helped a bit

Max Planck, said that “all matter originates and exists only by virtue of a force which brings the particles of an atom to vibration which holds the atom together. We must assume behind this force is the existence of a conscious and intelligent mind. This mind is the matrix of all matter.“
and ....from an old master ... Ancora impara!
