Oh, should have read the summary more closely. It's already in there.

Great for beginners.
Also includes more advanced ideas, like Bayes' Theorem and Central Limit Theorem, but presented conceptually.

Comment Re:Isotopes != elements (Score 5, Informative) 220
There is probably a cloud containing nothing but radon (the heaviest elemental gas) somewhere in the universe as well, right? If that exists would it disprove the big bang, or would it simply have been there by chance for billions of years, just like this one could have been?
Hydrogen and helium isotopes (and a little bit of lithium and beryllium) are made in the Big Bang. Everything heavier is made in stars. So these pure clouds can exist only as long as there are no stars nearby to pollute them with heavier elements. Stars are common in the modern universe, which is why it has been so hard to find such clouds.
Radon in particular is made in supernova explosions (and by the decay of radioactives which were made in supernova explosions) and there is no natural mechanism to separate it back out from mixtures of supernova debris. So in a sense, yes, if a massive, primordial, pure radon cloud was out there, it would disprove the Big Bang theory's prediction of nucleosynthesis, which can only make light elements.

The impact on Mercury which created the Caloris basin caused some wacky geology at the antipodal point to the collision. This is called "chaotic" or "weird" terrain. Link.

The edge like that because you see a shallower, thus cooler, portion of the sun's photosphere. As a cooler source of blackbody radiation, it looks darker and more orange. The phenomena is called limb darkening.
Robot Body Suit To Be Marketed In Japan 128
destinyland writes "A Japanese company is preparing limited mass production of a cybernetic bodysuit which dramatically increases user strength up to ten times. The "Hybrid Assistive Limb" suit synchronizes movements of a mechanical exoskeleton to biological nerve signals detected by biopads on the body. (Originally envisioned for people with disabilities, the suit also has industrial applications, and the company is planning annual production of 400 units at $4,200 apiece.) Its battery life is five hours, according to the company's web site, which promises they're also opening an EU branch to begin sales outside of Japan."
Women Skip Math/Science Careers To Have Families 616
hessian notes a Cornell survey, published in the Psychological Bulletin, of 35 years of sociological studies that concludes that women tend to choose non-math-intensive fields for their careers not because they lack mathematical ability, but because they want flexibility to raise children or prefer less math-intensive fields of science. "'A major reason explaining why women are underrepresented not only in math-intensive fields but also in senior leadership positions in most fields is that many women choose to have children, and the timing of child rearing coincides with the most demanding periods of their career, such as trying to get tenure or working exorbitant hours to get promoted,' said lead author Stephen J. Ceci... The authors concluded that hormonal, brain, and other biological sex differences were not primary factors in explaining why women were underrepresented in science careers, and that studies on social and cultural effects were inconsistent and inconclusive. They also reported that although 'institutional barriers and discrimination exist, these influences still cannot explain why women are not entering or staying in STEM careers,' said Ceci."
iPhone App Causes Google To Shut Down SMS Service 420
An anonymous reader writes "A few days ago, Inner Fence released a paid iPhone app called Infinite SMS, which let iPhone users employ Google's free SMS gateway to send SMS messages without paying their service providers. The resulting surge in traffic on Google's SMS gateway forced Google to block all third-party applications from using the free SMS feature — including Google's own GTalk client."
Comment Bad summary. (Score 5, Informative) 179
The summary misinterprets the results.
The instrument detects high-energy electrons. They found an excess (only 70, but statistically significant) with a particular energy, which if they come from a galactic source (like a pulsar), that source must be within 3000 light years. However, the researchers can't find an appropriate source.
Alternatively, this could be due to annihilating dark matter---the energy spectrum matches some models---but that's not necessarily coming from a particular source.
Voters Swayed By Candidates Who Share Their Looks 266
iandoh writes "Stanford researchers have found that voters are subconsciously swayed by candidates who share their facial features. In three experiments, researchers at the Virtual Human Interaction Lab worked with cheap, easy-to-use computer software to morph pictures of about 600 test subjects with photos of politicians. And they kept coming up with the same results: For the would-be voters who weren't very familiar with the candidates or in perfect lockstep with their positions or political parties, the facial similarity was enough to clinch their votes."

Given that Mozilla appears to be on a much faster cycle than Microsoft with this stuff, it's also possible that it could increase the gap even more before IE 8 is GA, no?"
