Time Enough

Sean Carroll has a new post at http://cosmicvariance.com/ and a new article in Scientific American about the direction of time. I had a couple of questions, but comments don't seem to be working (or visible) so I will just ask and see if anybody has any ideas.

(1)Sean makes much of the fact that a random initial state is very different from the extremely low entropy state from which our Universe apparently started. Doesn't Loschmidt's paradox force us to thing the same thing about any preceeding state? If the state of (say) one million years ago is randomly chosen from those that could give rise to the present, isn't it overwhemingly more likely that it was of much higher entropy than the present state? Exactly as much more likely, in fact, as that the state one million years in the future will have higher entropy than the present. (See e.g., http://en.wikipedia.org/wiki/Loschmidt's_paradox).

(2) Sean points out that the number of microstates doesn't change in the course of the evolution of the universe, and is presumably finite for a finite volume. How does this square with his multiplication of baby universe's scenario. Wouldn't you run out pretty soon?

Anti-Libertarian: re-post

The most pointed critique of social security and liberalism in general is the libertarian critique. The problem with libertarians, for a liberal, is that we have too much in common. We both believe in individual rights, tolerance of individual differences, and dislike government prescription of religion. The basic difference, it seems to me, is the different answers we give to Cain's (with thanks to the Captain - my original version had the corpse asking the question!) famous question: "Am I my brother's keeper?" That's not really my basic bitch against the libertarians though. My real complaint is the same as my complaint against most religion - its premise is a fraud. For those who can't stand to wait for the punchline, I believe that trying to implement libertarian principles leads to tyranny or social disintegration. Demonstrating that takes some historical (and pre-historical) context. For all but the last 15,000 or so of the 100,000 years the human spec

Uneasy Lies The Head

Uneasy lies the head that wears a crown ........... Shakespeare Henry IV, Part II. So it is with us and our slightly distant primate cousins , so it seems. A 9-year study of wild baboons in Kenya by Princeton University and the Institute of Primate Research may turn conventional assumptions of alphas males upside down. The study found that alpha males have high testosterone levels, which allows them to dominate other baboons, get access to more food, and attract better mates. This is expected. Surprisingly, though, the alpha males also have high levels of stress hormone glucocorticoid, which scientists measured from their feces samples. In fact, the stress of alpha baboons was on par with low-ranking baboons. The convention wisdom is that access to food and females provides life security and thus less stress for dominant males. Conversely, weak males who are constantly threatened by starvation and physical violence from stronger males are thought to be more stressed. The st

We Call it Soccer

The US played its best, and maybe only good game of World Cup, but lost thanks to brilliant goalkeeping by the Swedish keeper and the bizarre method soccer uses to settle ties when three US stars could not put the ball on frame from the 12 yard spot.  At the end it came down to a blocked shot that spun in by maybe a couple of centimeters. Well, that's football - too much like life.   Which brings me to a modest proposal.  Replace the thirty minute overtimes with as many 7-player 15 minute periods as needed to settle it.  Scoring should be much easier with fewer players.
