So here comes the latest pop psychology, the extraordinary, ultimate authority “science” says not to date muscular men, but their alternative, scrawny men. Why? Because a correlation between muscularity and sexism, from an uncited study, claims so. First off, the strength of the correlation is not shared. This could be a very weak correlation, meaning that plenty of… Read the rest
The standard complaints against science is that it is influenced by money, which in turn leads to deliberate or unconscious manipulation of data. Contradictory findings are may not be published, either out of a belief they are wrong or a realization that they aren’t.
But the real source of the problem is only now becoming more recognized: the structure… Read the rest
Summarizing from PLoS Blogs:
A review article in the highly acclaimed CMAJ finds cigarettes may be beneficial for long distance runners.
Serum hemoglobin is related to endurance running performance. Smoking is known to enhance serum hemoglobin levels and (added bonus), alcohol may further enhance this beneficial adaptation.
Lung volume also correlates with running performance, and training increases

The Maldives is a small island state with the unfortunate attribute that its highest peak comes in at about 2.5 metres above sea level (a metre is like a decimal-based yard – try it, you’ll like it). This means that just a little bit of melted polar ice will suffice to turn their islands into reefs. Understandably enough, Read the rest
First an easy physics problem. Say you throw a ball into the air. Which part of the trip takes longer, the way up or the way down?
Did you account for the way the Earth’s gravitational field varies during the ball’s flight? How about its relativistic mass gain? The energy of rotation as the ball spins? Hopefully not,… Read the rest
On the OP-ed column of New York Times last Friday Martin Lindström effectively misunderstands basic concepts of brain functioning and causality. This is made all the more sadder by the fact Lindström is an author of Buyology – Tryth and Lies About Why We Buy and Brandwashed, in the former of which he claims to have gathered… Read the rest
This is the first part of a documentary about how civilization is on its way to collapse because of global warming, peak oil, overpopulation, etc. Pretty much every hobgoblin of the “fear the future” movement is in here, so it’s worth watching the entire series as it makes for a good overview of that entire system of thinking.… Read the rest
Researchers demonstrate flexible ePaper phone
I love the technology on display here, and I think that it will definitely take off in some application or other as soon as it becomes economical to mass-produce. But what interests me more than the tech are the comments made by Roel Vertegaal, one of the project’s leaders.
The computer looks, feels… Read the rest
SETI program has been closed down. The odds were against it ever making contact. But that wasn’t the point.
“I always hear stories about how we can’t find engineers, and that’s why we’re emphasizing Math and Science … We want to start making Science cool. I want people to feel about the next big energy breakthrough and the next big Internet breakthrough the same way they felt about the moonwalk.”
So said President Obama at a town… Read the rest
In a previous article, “Is Science Just a Matter of Faith?” I argued that for non-scientists, science is a matter of belief–faith, if you will–in the statements made by authority figures about science. An article in Mother Jones, “The Science of Why We Don’t Believe Science”, presents a series of very elaborate and rather convoluted propositions from… Read the rest
About 10 years ago there was a debate in Canada about whether Canadian NHL teams should receive a subsidy to be able to compete with big-market American teams. As soon as somebody came up with the soundbite “no millions for millionaires”, the plan promptly died. This makes the phrase a remarkable innovation that you should keep handy in… Read the rest
Science supports the prevailing stereotypes:
Using data from MRI scans, researchers… found that self-described liberals have a larger anterior cingulate cortex–a gray matter of the brain associated with understanding complexity. Meanwhile, self-described conservatives are more likely to have a larger amygdala, an almond-shaped area that is associated with fear and anxiety.
That paragraph is pretty… Read the rest
Solarsystemscope is an online… planetarium? which is much more user friendly than the downloadable Celestia. (And if you go with Celestia, check out the add ons.)
It’s fun to play with, and kids will instantly understand how days and nights, seasons, eclipses, and prophecies are produced. “Oh, so that’s how you Revelations 6:12 it!”… Read the rest
Ann Coulter saysJapan’s nuclear troubles are good news. This could be phrased as “Ann Coulter says something pseudo-provacative. It’s her job.”
Reading the article, I cringe , of course, for the researchers whose work she is overzealously extending at best. No one wants to be known as that guy who said nuclear meltdowns are the bomb.
But there’s… Read the rest
A previously empty bucket. A man has filled that bucket only 50 red balls and 50 black balls (but you can’t see inside as you are picking.) Choose a color, red or black; now reach in to pull out a ball. If the ball you pick matches the color you chose, you win $10000.
1. Which color should you… Read the rest
National Academy of Sciences study finds that FBI’s anthrax evidence is inconclusive. Now to the voir dire
If the origin of the anthrax cannot be determined conclusively through science, should a jury be able to conclude based on their assessment of non-scientific evidence that the anthrax originated from a suspect beyond a reasonable doubt? Likewise, should a jury simply ignore the other non-scientific evidence and conclude that the inconclusive scientific results constitute reasonable doubt?
If science… Read the rest
