Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount.

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.
