Cycles of Time

Penrose's new book, Cycles of Time, is due out soon. This discusses his own thermodynamic cosmology, in which there are slowly decaying masses and information loss. Wrong for sure, but a step in the right direction.

A recent interview also mentions another upcoming book by Penrose, entitled Fashion, Faith and Fantasy in the New Physics. Faith questions the idea that quantum mechanics is the final word on the universe, Fantasy is the standard cosmology and Fashion is being a stringer. Some, such as Woit, would argue that being a stringer is no longer the fashion, but they still seem to have most of the jobs.

Meanwhile, kneemo provides the link to Strings 2010 in Texas. My broadband limitations will not allow me to watch seminars online, so please comment if there is anything interesting here, or elsewhere.

A talk I surely recommend is Lance Dixon's Perturbative Ultraviolet Behavior of N=8 Supergravity.

If you have Mathematica handy, check out the 50 N=8 4-point cubic vacuum graphs contained in the auxiliaryData archive here.

kneemo, it was a struggle to download the ppt file. I certainly do not have Mathematica. But thanks for the tip.

Penrose is going to be at the FFP11 conference. I'm seriously thinking of going, if I can get enough relatives to pony up the money.

Hi Carl. Penrose is a really nice guy. I hope you make it. Personally, I can't decide between (1) bumping ski lifts for the winter or (2) cleaning or something.
