The nation was left reeling yesterday by the revelation that the presidential election of 2008 was a hoax.

The truth at last! The nation was left reeling yesterday by the revelation that the presidential election of 2008 was a hoax. Key quote:

O’Keefe said he also expected the ruse would be unmasked when Obama said that “under my plan of a cap-and-trade system, electricity rates would necessarily skyrocket,” and again when Obama claimed, “I’ve now been in 57 (U.S.) states,” with “one left to go.”

“We modeled the 57-states gaffe on Dan Quayle’s ‘potatoe’ mistake,” said O’Keefe, referring to a 1992 incident at a Trenton, N.J., elementary school in which then-Vice President Dan Quayle added an “e” to “potato.” “We figured Obama would become a national laughingstock like Quayle, (but we) underestimated the tendency of the press and the public to forgive mistakes by people they like.”

First results from the Hayabusa asteroid samples

3:52 pm

First results from the Hayabusa asteroid samples.

A preliminary analysis of asteroid samples returned last year by Japan’s Hayabusa probe show evidence the dust grains have a similar composition to stony meteorites that commonly fall to Earth. . . . The initial research also shows the samples inspected so far contain no organic molecules. Scientists also say the analysis confirms the rocks at Itokawa were formed 4.6 billion years ago at the dawn of the solar system.

A detailed explanation of what has happened at the Fukushima nuclear power plant

8:43 pm

Check out this detailed engineering explanation of what has happened, is happening, and will happen at the Fukushima nuclear power plant in Japan. Key quote:

The point is that the nuclear fuel has now been cooled down. Because the chain reaction has been stopped a long time ago, there is only very little residual heat being produced now. The large amount of cooling water that has been used is sufficient to take up that heat. Because it is a lot of water, the core does not produce sufficient heat any more to produce any significant pressure. Also, boric acid has been added to the seawater. Boric acid is “liquid control rod”. Whatever decay is still going on, the Boron will capture the neutrons and further speed up the cooling down of the core.

TSA to retest airport body scanners for radiation

10:25 pm

Does this make you feel safer? The TSA is going to retest the radiation levels of all its airport body scanners after maintenance records on some showed levels 10 times higher than expected. Also this:

The TSA is responsible for the safety of its own X-ray devices. The U.S. Food and Drug Administration has said it does not routinely inspect airport X-ray machines because they are not considered medical devices. The TSA’s airport scanners are exempt from state radiation inspections because they belong to a federal agency.

David Horowitz Takes on Muslim Students at Brooklyn College

5:06 pm

So who are the real hate-mongers here? David Horowitz speaks at Brooklyn College while under heavy security. To me, the key quote is this:

Mr. Horowitz began by ruefully observing, “When I went to college you didn’t need all of this security on campus, but things have changed and that’s the reason we now need checkpoints on campuses. Checkpoints are essential to defend against terrorists and Jew haters.” Adding that he has been verbally and physically assaulted on campuses around the country for his forthright views, he said, “Our campuses are controlled by liberal fascists and it is a movement to suppress the free speech rights of conservatives.”

Random variations are still too large for climate models

3:00 pm

The uncertainty of science: a paper published today in Geophysical Research Letters has concluded that the the long term random variations of the climate, sometimes lasting as long as three or four decades, are large enough to hide any actual changes to the climate. In the quote from the abstract below, the term “random walk” is jargon for a long term random fluctuation having nothing to do with climate change.

This result indicates that the shorter records may not totally capture the random variability of climate relevant on the time scale of civilizations, for which the random walk length is likely to be about 30 years. For this random walk length, the observed standard deviations of maximum temperature and minimum temperature yield respective expected maximum excursions on land of 1.4 and 2.3°C and over the ocean of 0.5 and 0.7°C, which are substantial fractions of the global warming signal.

In other words, it might simply be too soon to be making predictions about the climate, based upon the presently available data.
