The Daily Parker

Scientists will soon have access to samples from a box of moon rocks that no one has opened since Neil Armstrong sealed it on the moon 50 years ago:

The upcoming experiments, on vacuum-sealed cores and a long-frozen rock, can be performed only once, at the precise moment the samples are opened. That’s why the materials have been held back since they were retrieved from the moon, said Ryan Zeigler, who curates the Apollo rocks collection. NASA was waiting for the right scientists, with the right technologies, at the right time.

With Apollo 11’s 50th anniversary this year and renewed interest in the moon ahead of a proposed return mission, Zeigler said, the right time is now.

Before the Apollo 11 mission, scientists couldn’t agree on where the moon came from. It’s a misfit in the solar system — much larger relative to its planet than almost any other moon. Some speculated that it was once an independent object that was “captured” by Earth’s gravity. Others proposed that the satellite formed in orbit alongside Earth when the planets were coalescing out of a primordial dust disc. Many grade-school textbooks taught that it was, in fact, a blob of Earth that had been flung away by our planet’s spin; the Pacific Ocean was thought to be a scar from this ancient loss.

All of those theories had to be discarded as soon as scientists saw the first Apollo rocks.

About 4.5 billion years ago, the theory goes, a long-gone giant planet called Theia, named for the mother of the Greek moon goddess, smashed into the newly formed Earth. The impact shattered both Theia and the proto-Earth and splashed millions of tons of material into space. Some of the rock coalesced in orbit around the Earth, and our satellite was born. The heaviest bits sank to the moon’s center, while the light minerals floated to the top of the worldwide magma ocean and crystallized, forming the thin anorthosite crust. The rocks and dust retrieved by Armstrong and Scott are relics of this long-ago tumult.

How cool! And how loony, in a sense. I can't wait to see whether they get evidence in support of the hypothesis.

University College of London researchers John Jerram and Nikki Shure have evidence that rich North American men are the most likely to employ bullshit:

Study participants were asked to assess their knowledge of 16 math topics on a five-point scale ranging from “never heard of it” to “know it well, understand the concept.” Crucially, three of those topics were complete fabrications: “proper numbers,” “subjunctive scaling” and “declarative fractions.” Those who said they were knowledgeable about the fictitious topics were categorized as BSers.

Using a data set spanning nine predominantly English-speaking countries, researchers delineated a number of key findings. First, men are much more likely than women to master the art of hyperbole, as are the wealthy relative to the poor or middle class. North Americans, meanwhile, tend to slip into this behavior more readily than English speakers in other parts of the globe. And if there were a world championship, as a true devotee might appreciate, the title would go to Canada, data show.

Finally, a between-country comparison finds that young people in Canada and the United States are the most likely to over-sell themselves overall, with those in Europe being much less likely to engage in such behavior.

Taken as a whole, the results appear to suggest that the countries with the greatest propensity toward bombast also have the smallest variances between groups living within them. In the U.S. and Canada, for instance, there may simply be so much BS going around that everyone ends up partaking in it.

The paper is available from IZA.

Wherever a landmass had several kilometers of ice on top, it deformed. Glaciers covered much of North America only 10,000 years ago. Since they retreated (incidentally forming the Great Lakes and creating just about all the topography in Northern Illinois), the Earth's crust has popped back like a waterbed.

Not quickly, however.

But in the last century, Chicago has dropped about 10 cm while areas of Canada have popped up about the same amount:

In the northern United States and Canada, areas that once were depressed under the tremendous weight of a massive ice sheet are springing back up while others are sinking. The Chicago area and parts of southern Lake Michigan, where glaciers disappeared 10,000 years ago, are sinking about 10 to 20 cm each century.

One or 2 millimeters a year might not seem like a lot, but “over a decade that’s a centimeter. Over 50 years, now, you’re talking several inches,” said Daniel Roman, chief geodesist with the National Oceanic and Atmospheric Administration. “It’s a slow process, but it’s a persistent one.”

While Chicago’s dipping is gradual, this dynamic could eventually redefine flood plains and work against household sewer pipes that slope downward to the sewer main.

The same phenomenon has affected the UK as well. Scotland is popping up and England is sinking, as are other pairs of regions similarly glaciated. (Sterling, however, has a long way to go...)

Beth Moses describes her first flight on the Virgin Galactic space ship on Friday:

I mean. C'mon. That's cool.

I've had a lot going on this week, including seeing an excellent production of Elektra at Lyric Opera of Chicago last night, so I haven't had time to read all of these articles:

• A 12-year-old journalist in southern Arizona stands up to the local marshal and wins.
• The US Dollar is still the world's reserve currency—and in fact foreigners are buying more than ever.
• The Jussie Smollett case was the least important of a number of stories in the news this week.
• The North Carolina 9th shows us an "important lesson about election and voter fraud."
• The Times predicts who will win the big awards at the Oscars tomorrow night.
• Developers have proposed a huge new neighborhood over the Metra Electric tracks west of Soldier Field.
• Zebra stripes appear to defend against deadly flies.

And I shall begin reading these...soon. Maybe tomorrow. Sigh.

One of my friends from high school, Beth Moses, today became the 571st person to travel into space:

Virgin Galactic sent three human beings on Unity for the first time in Friday's supersonic test flight, which reached three times the speed of sound on its way up. Just before the flight, Richard Branson's space tourism company told CNBC that astronaut trainer Beth Moses is on the company's spacecraft Unity, along with the two pilots.

"Beth Moses is on board as a crew member," a Virgin Galactic spokeswoman told CNBC. "She will be doing validation of some of the cabin design elements."

The mission launched horizontally, rather than the traditional vertical method of launching rockets. The jet-powered mothership Eve lifted the spacecraft Unity, taking off from the Mojave Air and Space Port. Upon reaching an altitude above 40,000 feet, the carrier aircraft released Unity.

MacKay and Masucci then piloted the spacecraft in a roaring burn. The flight pushed Unity to a speed of Mach 3, which is three times the speed of sound, as it screamed into a climb.

After performing a slow backflip in microgravity, Unity turned, gliding back to land at the runway it took off from about an hour earlier. Unity is the name of the spacecraft built by The Spaceship Company, which Branson also owns. This rocket design is officially known as SpaceShipTwo.

When Beth was in high school, she said she wanted to be an astronaut. After a long career at NASA she joined Virgin Galactic as their chief astronaut instructor. And today, she made history.

Congratulations, Beth! You're officially out of this world.

First, William Giraldi, writing in Medium, proclaims "[e]verything you need to know about the mess that is America in 2019 can be explained by our deepening national belief that Bigfoot is real:"

Bigfooters believe they are questing for bipedal apes in California, but they are really questing for their own lost boyhoods, their Boy Scout days, those formative experiences in the woodlands of fancy and faith, and for the thrill of certain belief as it was before the adult world broke in to bludgeon it.

Remember that preadolescent frisson, the dread-tinged excitement of knowing, absolutely knowing, that monsters were real, not the myths, folklores, and allegories that adulthood insists they are? If Wordsworth laments adulthood’s injection of sobriety and rationality into the childhood sublime, Bigfooters aren’t having it. They’ve found a means of resurrecting that boyish wonder, of plugging back into the child’s reciprocal, imaginative bond with nature. If it comes at the cost of evidence — to say nothing of dignity — since when have children ever bothered with evidence? These scientists and their mocking, scoffing facts are a drag. What did John Keats says about Isaac Newton’s achievements with light? “He destroyed the poetry of a rainbow by reducing it to a prism.”

In concert with their wish to plug back into their boyhoods, these men, loose in the woods, are searching for the approval and acceptance of other men. No optional male group endeavor, none, is exempt from this law, one that hearkens back to the mastodon hunt, during which a male proved himself worthy of the clan and thus worthy of the protection and resources the clan controlled.

Which isn’t to say that time in the woods is idyllic. Believer and journalist John Green, the grandfather of Sasquatchia, once wrote, “The average sasquatch hunter is so pig-headed that two of them together are pretty sure to have a falling out before long… People who will go hunting for an animal that is rejected by the world of science and almost everybody else are bound to be people who don’t pay much attention to any opinion but their own, and expect not only to have an opinion but to act on it.”

Remember Jonathan Swift: “Reasoning will never make a Man correct an ill Opinion, which by Reasoning he never acquired.”

Our second story comes from the CBC via IFLScience, showing that our Canadian neighbors have shown a disturbing lack of immunity to our American anti-intellectualism.

It seems a Vancouver dad worried so much about the (totally discredited) myth that vaccines cause autism that he didn't get his kids vaccinated. Flash forward 10 years and add a family trip to Vietnam, and one of his kids became Patient Zero in a British Columbia measles outbreak:

[Emmanuel] Bilodeau believes one of his three sons contracted measles during a family trip to Vietnam earlier this year and that it has since spread at the French-language schools his children attend.

Bilodeau said he brought his sons to a travel clinic on Broadway Street before their trip where they received other vaccinations, but not for measles.

It was on the plane ride home that his 11-year-old son began experiencing symptoms, including fever.

Measles. In 2019. In Canada, which has perhaps one of the three or four most advanced health-care systems the world has ever seen.

So, go ahead and believe in 3-meter-tall ape-people wandering the forests of Oregon, but try to apply some logic and rationality to life-or-death decisions like whether to prevent people from getting a disease so easy to prevent we had almost eradicated it before the beginning of this century.

New thinking says longer ago than you might think—with implications throughout the animal kingdom:

If [Attention Schema Theory (AST)] is correct, 300 million years of reptilian, avian, and mammalian evolution have allowed the self-model and the social model to evolve in tandem, each influencing the other. We understand other people by projecting ourselves onto them. But we also understand ourselves by considering the way other people might see us. Data from my own lab suggests that the cortical networks in the human brain that allow us to attribute consciousness to others overlap extensively with the networks that construct our own sense of consciousness.

Maybe partly because of language and culture, humans have a hair-trigger tendency to attribute consciousness to everything around us. We attribute consciousness to characters in a story, puppets and dolls, storms, rivers, empty spaces, ghosts and gods. Justin Barrett called it the Hyperactive Agency Detection Device, or HADD. One speculation is that it’s better to be safe than sorry. If the wind rustles the grass and you misinterpret it as a lion, no harm done. But if you fail to detect an actual lion, you’re taken out of the gene pool. To me, however, the HADD goes way beyond detecting predators. It’s a consequence of our hyper-social nature. Evolution turned up the amplitude on our tendency to model others and now we’re supremely attuned to each other’s mind states. It gives us our adaptive edge. The inevitable side effect is the detection of false positives, or ghosts.

And so the evolutionary story brings us up to date, to human consciousness—something we ascribe to ourselves, to others, and to a rich spirit world of ghosts and gods in the empty spaces around us. The AST covers a lot of ground, from simple nervous systems to simulations of self and others. It provides a general framework for understanding consciousness, its many adaptive uses, and its gradual and continuing evolution.

The author makes a strong argument that many vertebrates, including canids and corvids, have consciousness as we understand it, just so they can make sense of the world. It's an intriguing theory.

Note, also, that both the article and I use "theory" in its scientific sense: a hypotheses repeatedly tested and not yet falsified.

Demographers Richard Florida and Karen King crunched some numbers to determine which metro areas had more single men or single women. Some findings:

In absolute numbers, heterosexual men have a considerable dating advantage in metros across the East Coast and South. New York City  has more than 200,000 more single women than men; Atlanta 95,000 more; Washington, D.C. 63,000 more; Philadelphia nearly 60,000 more. The pattern continues for Baltimore and Miami. Meanwhile, the opposite is true out West, where the absolute numbers favor heterosexual single women. San Diego has more than 50,000 more single men than women; Seattle has 46,000 more; San Jose has 37,000 more; Phoenix 32,000 more. The pattern is similar for Denver and San Francisco.

Overall, more than 60 percent of metros (234 metros) lean male, and about a third (136) lean female. There are a dozen metros where the odds are more or less even.

Among large metros (with more than one million people), tech-driven San Jose has the smallest ratio of single women to men (868 per 1,000). But across all metros, the geography is more varied. Jacksonville, North Carolina; Hanford-Corcoran, California; The Villages, Florida (a retirement community); and the Watertown-Fort Drum, New York all have ratios of 500-600 single women to 1,000 single men.

The map for singles aged 45 to 64 shows the odds shifting sharply, simply because women tend to outlive men. The map is almost entirely orange: By this age, single men have the advantage in most metros across the country.

Of course, this analysis does not account for factors that often influence our mating life. We don’t know the sexual orientation of these singles—a huge factor—nor does our analysis account for education, race, or ethnicity; or those people who are in relationships but not yet married.

Now put your hands up!
