Quote of the day

After I'd come to understand evolution and know a little about history and farming, I saw that the thick white animals I laughed at for following each other around and getting caught in bushes were the product of generations of farmers as much as generations of sheep; we made them, we moulded them from the wild, smart survivors that were their ancestors so that they would become docile, frightened, stupid, tasty wool producers. We didn't want them to be smart, and to some extent their aggressiveness and their intelligence went together. Of course, the rams are brighter, but even they are demeaned by the idiotic females they have to associate with and inseminate.

The same principle applies to chickens and cows and almost anything we've been able to get our greedy, hungry hands on for long enough. It occasionally occurs to me that something the same might have happened to women but, attractive though the theory might be, I suspect I'm wrong.

Quote of the day

"One important detail is that actions that have not yet been tried in a state s are always assumed to lead immediately to the goal with the least possible cost, namely h(s). This optimism under uncertainty encourages the agent to explore new, possibly promising paths.

- Artificial Intelligence: A Modern Approach (Russell&Norwig)

Amusing how theory can guide one's life as well as explain the inevitable disappointments. Of course, Mae West anticipated theory with "Whenever I have to choose between two evils, I always like to try the one I haven't tried before"

Quote of the day

"The more often you swear in everyday life, the less it reduces pain when you're hurting"

Yes, you've got to be an economics fan to make sense of the title of the piece where I found the original: Toward a theory of optimal swearing seigniorage

And yes, that not only sounds clever but refers to an actual study.

Things you learn reading Mary Roach's "Packing for Mars"....

Regarding the fittings for urine collection in space suits: "To avoid mishaps caused by embarrassed astronauts opting for L when they are really S, there is no S.  'There is L, XL, and XXL', says Hamilton Sundstrand suit engineer Tom Chase."

Monkey business...

I thought I blogged this before, but it looks like I was only intending to.  I mentioned at a party today a study in which economists found similar behavior to ours in monkeys - areas in which monkeys are not only as irrational as we are in our decisions, they are actually irrational in the same way.

Laurie Santos describes the study in this talk here.  Of course, in order to study how monkeys use money, first they have to be taught to use money in the first place.  And once monkeys understand the value of money, they engage in thievery (as described in the talk above) and even prostitution.

If you don't want to watch the whole video, the Freakonomics guys describe the same experiment here, including:

Something else happened during that chaotic scene, something that convinced Chen of the monkeys' true grasp of money. Perhaps the most distinguishing characteristic of money, after all, is its fungibility, the fact that it can be used to buy not just food but anything. During the chaos in the monkey cage, Chen saw something out of the corner of his eye that he would later try to play down but in his heart of hearts he knew to be true. What he witnessed was probably the first observed exchange of money for sex in the history of monkeykind. (Further proof that the monkeys truly understood money: the monkey who was paid for sex immediately traded the token in for a grape.)

Vuvuzela virtuoso visiting Eastman Theatre?

Seems unlikely, but clearly so far the biggest winner at the World Cup is this delightful little instrument - and the biggest losers are those condemned to have to hear it unwillingly. Perhaps, as with garlic, the solution is "If you can't beat them, join them."

Now we can not only see any web site to the background of vuvuzela sounds, youtube has added a gadget (soccer ball shaped) that lets you mix the audio of the clip with the appropriate sounds.

Another loser would be astrology, after France rather convincingly showed that it is NOT useful when selecting your soccer team.


Update: the horror!

I'll deal with it somehow....

A new study purports to show that exposure to beautiful women is bad for men's health. By some strange circumstance, I am still alive today. This is anectodal counter-evidence at best, but I must agree with the source that this study is suspect. The criticisms are not only funny but right on the mark.



Hat tip Skepchiks.

Is it just how submissive the little dears are, then?

I am generally open minded, but for the longest time I have believed that the two areas in which women were simply inferior to men were weightlifting and chess. I concluded the latter back in my chess playing days when I was perusing the ratings tables in Chess Life & Review. If I had been a woman, my rating would have placed me in the top ten women in the United States. As a man, I wasn't even in the top thousand. That doesn't mean NO women could beat me, but it does suggest amazingly few...and there were many men in the "no woman could beat me" category. Yes, I'm sure that women are not encouraged to play chess as much as men are (not that a "nerd" reputation is all THAT prized even among men), but the difference just seemed SO extreme there had to be some sort of biological factor.

Now I see this study. In short: no. Now I'm not saying this study (42 pairs of various skill levels) completely dispels my notion - how many of those pairs were tournament level players? - but it certainly weakens my case...and it would provide another explanatory mechanism if women just like to lose (to a guy - the women apparently played harder if they THOUGHT they were playing against another woman).

Any of you girls want to help me out lifting this heavy package?

Planetary news

Despite losing one of its stripes, Jupiter will remain a planet.

Even if Pluto gained one, it still wouldn't be.

Funny in hindsight....

The sign is pretty good, but I like the commentary even better.

The perils of superstition....

I am sometimes concerned that some of my friends put too much faith into romantic little oddities such as astrology. But at least they don't usually perform human sacrifices in order to improve their product, although I suppose one should admire the dedication....

Quote of the day

Lies were also categorised as to whether they were self-oriented or other-oriented with men telling more self-oriented lies than women. Overall, though, men and women told about the same number of lies, contrary to the popular conception that men are bigger liars than women.
- Feldman et al

All science aside, men are still more likely to lie about the size of their sexual organs.

Most useless dating advice of the month

I rather enjoyed this article, but there was a glaring omission.

The article describes how men's dance moves were judged by women, and "women gave the highest attractiveness ratings to men with the highest levels of prenatal testosterone." So if you're a guy, and you want to glitter underneath that disco ball, just make sure you are exposed to plenty of testosterone while you are still in the womb.

In case you're wondering, yes, I had a high level of prenatal testosterone (PT). The way they determine this is to compare the length of your index finger to that of your ring finger. If your ring finger is longer, high level of PT. The bigger the disparity, the higher the PT.

Interestingly, and I have no idea what this means - if anything, the difference is greater on my right hand than my left: 1/2 a fingernail compared to 1/4 a fingernail.

Fun article, but couldn't they have given the poor male readers at least ONE dance move guaranteed to look good?

Probably not the equitable way to make your point....

Coyote sarcastically points out that the ShowYourVote website, which gives you a chance to show your support a "fair and effective" climate deal at the Copenhagen summit is a rather one-sided approach to voting - there is only one way you can vote.

I commented that this appears to me to be a project by an influential (since he posts on the official Google blog) individual at Google rather than a project BY Google.

It really should have been called "Show Your Support" rather than "Show Your Vote" to avoid the absurdity.

If the LHC had a sense of humor, they would announce that they are indeed going to try to create a man-made black hole and that the test is currently scheduled for December 21, 2012.

...at the science quiz linked by the Bad Astronomer.

Of course I got them all right, none of the questions are obscure, although I did have some doubts about one of the questions. But it's interesting how many people miss quite a few, taking it will let you see the statistics.
