Want to learn something of the geology of the Grand Canyon?

2:10 pm

Want to learn something of the geology of the Grand Canyon? The Geological Society of America has just published a special volume of papers, with the introductory and afterword [pdf] chapters available online.

Those two chapters provide a very good layman’s summary of the geological state-of-the-art of the Grand Canyon. Very worthwhile reading if you plan to hike down in the near future.

Scientists now think it is possible for there to be floating methane ice on the lakes of Titan.

Scientists now think it is possible for there to be floating methane ice on the lakes of Titan.

Up to this point, Cassini scientists assumed that Titan lakes would not have floating ice, because solid methane is denser than liquid methane and would sink. But the new model considers the interaction between the lakes and the atmosphere, resulting in different mixtures of compositions, pockets of nitrogen gas, and changes in temperature. The result, scientists found, is that winter ice will float in Titan’s methane-and-ethane-rich lakes and seas if the temperature is below the freezing point of methane — minus 297 degrees Fahrenheit (90.4 kelvins). The scientists realized all the varieties of ice they considered would float if they were composed of at least 5 percent “air,” which is an average composition for young sea ice on Earth. (“Air” on Titan has significantly more nitrogen than Earth air and almost no oxygen.)

The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"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. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

Bank of America arbitrarily froze the account of a firearms manufacturer because, in their words “We believe you should not be selling guns and parts on the Internet.”

Facism: Bank of America arbitrarily froze the account of a firearms manufacturer because, in their words “We believe you should not be selling guns and parts on the Internet.”

Quite rightly, the owner of the company told them they had “no right to make up their own rules” and that he was going to take his business elsewhere. I think every gun owner in the country should do the same.

The Kepler science team today revealed an additional 461 candidate exoplanets, with four being less than twice Earth’s size and in the habitable zone.

Worlds without end: The Kepler science team today revealed an additional 461 candidate exoplanets, with four being less than twice Earth’s size and in the habitable zone.

Since the last Kepler catalog was released in February 2012, the number of candidates discovered in the Kepler data has increased by 20 percent and now totals 2,740 potential planets orbiting 2,036 stars. The most dramatic increases are seen in the number of Earth-size and super Earth-size candidates discovered, which grew by 43 and 21 percent respectively. The new data increases the number of stars discovered to have more than one planet candidate from 365 to 467. Today, 43 percent of Kepler’s planet candidates are observed to have neighbor planets.

Of these candidates, 105 have so far been confirmed to be exoplanets by other methods.

Note that these Kepler planets are in addition to the fifteen new exoplanets noted in my previous post.

The Sun crashes

10:27 am

NOAA today released its newest monthly update of the Sun’s sunspot cycle and, as I do every month, I have posted the latest graph, with annotation, below the fold.

The sunspot numbers for December were not only startlingly low, they actually plunged to levels not seen since May 2011, at a time when the Sun is supposed to be approaching sunspot maximum and the number of sunspots is supposed to be increasing.

The future of the social security program is worse than you think.

The future of the social security program is worse than you think.

For the first time in more than a quarter-century, Social Security ran a deficit in 2010: It spent $49 billion dollars more in benefits than it received in revenues, and drew from its trust funds to cover the shortfall. Those funds — a $2.7 trillion buffer built in anticipation of retiring baby boomers — will be exhausted by 2033, the government currently projects.

And this is from the New York Times, of all places! Of course, as soon as any politician suggests instituting any of the reforms suggested in the article the Times will then start screaming bloody murder in protest. They are very good at appearing nuanced and thoughtful about the debt, until someone actually suggests doing something about it.

On Wednesday Apophis will pass the Earth at a distance of 9 million miles, allowing astronomers to gather more data about this asteroid’s orbit and composition.

Having crossed outside Earth’s orbit, Apophis will appear briefly in the night-time sky. Wednesday 9 January will afford astronomers the rare opportunity to bring a battery of telescopes to bear: from optical telescopes to radio telescopes to the European Space Agency’s Infrared Space Observatory Herschel. Two of the biggest unknowns that remain to be established are the asteroid’s mass and the way it is spinning. Both of these affect the asteroid’s orbit and without them, precise calculations cannot be made.

A survey of 9 million students over the past 47 years has found that modern students consider themselves above average in education, self-confidence, and determination, despite test scores showing an actual drop in these skills.

The Obama generation: A survey of 9 million students over the past 47 years has found that modern students consider themselves above average in education, self-confidence, and determination, despite test scores showing an actual drop in these skills.

While students are much more likely to call themselves gifted in writing abilities, objective test scores actually show that their writing abilities are far less than those of their 1960s counterparts. Also on the decline is the amount of time spent studying, with little more than a third of students saying they study for six or more hours a week compared to almost half of all students claiming the same in the late 1980s. Though they may work less, the number that said they had a drive to succeed rose sharply.

And then there’s this:

[O]ne in four recent students responded to a questionnaire called the Narcissistic Personality Inventory with results pointing towards narcissistic self-assessments. Narcissism is defined as excessive self-love or vanity; self-admiration, or being self-centered. [Pyschologist Jean] Twenge said that’s a trait that is often negative and destructive, and blames its boom on several trends – including parenting styles, celebrity culture, social media, and easy credit – for allowing people to seem more successful than they really are.

No wonder they voted for Obama. They are just like him, egotistic, narcissistic, and uneducated.

The study also found that these traits, high self esteem combined with low skills, eventually results in disaster for the individuals involved. They grow up depressed, anxious, and unsatisfied with life.

Consider that a prediction of the future for the country as a whole.

Alan Grayson returns to Congress and immediately calls Republicans terrorists.

7:22 pm

Leftwing civility: Democrat Alan Grayson returns to Congress and immediately calls Republicans terrorists.

That Democratic voters were willing to re-elect this vicious hateful guy back into Congress is proof to me that these voters really have no good will, are eager to demonize the opposition, and would possibly even approve violence against that opposition to achieve their ends. (Among Grayson’s many offensive acts, he once appeared uninvited at an opponent’s rally and refused to shut up, closing the entire event down. I just can’t find the link at this moment.)

The Byrds – Turn. Turn. Turn.

An evening pause: The words, except for the very last line (inserted by Pete Seeger), are from the book of Ecclesiastes.

To every thing there is a season, and a time to every purpose under the heaven.

Read it all, especially the King James version. It is one of the most profound and beautiful poems ever written.
