Saturday: Hili dialogue

December 10, 2016 • 6:30 am

It’s Saturday, December 10, and the snow is on its way to Chicago: 5-10 inches are predicted for this afternoon and later. Fortunately, part of my retirement benefits include a free spot in the nearby University parking garage, where I will install my car before the storm hits. (Believe me, in my pre-retirement days when I parked on the streets, I’ve waited over two weeks for the snow to melt enough to dig my car out of big drifts). It’s National Lager Day in the U.S., but I may have an IPA instead, though I’m increasingly finding them too bitter since American craft brewers are overwhelming beers with too many hops. I dearly miss a good British pint like Landlord. It’s also International Human Rights Day, honoring the UN’s proclamation in 1948 of The Universal Declaration of Human Rights. That resolution was adopted by a vote of 48-8. Who voted against it? Saudi Arabia, the USSR, Ukrainian SSR, Yugoslavia, Poland, South Africa, Czechoslovakia, and Byelorussian SSR.

Other events on this day in history include Martin Luther’s burning of his copy of the his copy of the  Exsurge Domine in Wittenberg; the Bull censured many of Luther’s famous 95 theses. Into Luther’s bonfire also went other documents of canon law and Catholic theology. On this day in 1684, Newton read to the Royal Society his paper deriving Kepler’s laws from the principle of gravity.  In 1884, Mark Twain’s Huckleberry Finn was published; Ernest Hemingway, a big fan of the book, said this: “All modern American literature comes from one book by Mark Twain called Huckleberry Finn.  American writing comes from that. There was nothing before. There has been nothing as good since.” Strong words, and an arguable thesis, but defendable nonetheless. In England, Edward VIII abdicated on this day in 1936, and, in 1978 the Nobel Committee, in a stunning move of premature plaudits, gave the Nobel Peace Prize to Prime Minister of Israel Menachem Begin and President of Egypt Anwar Sadat. Peace? Not by a long shot. It was a good try, though.

Notables born on this day include Ada Lovelace (1815), Emily Dickinson (1830), and the choreographer Hermes Pan (1909).  Those who died on this day include Alfred Nobel (1896), Walter Johnson (1946), Jascha Heifetz (1987), Rick Danko (1999), and Richard Pryor (2005). Meanwhile in Dobrzyn, Hili is musing in Greek. I’d amend her statement to “Time flies—and so do the birds.” Looking up “Panta rhei,” though, it seems to mean “Everything flows,” i.e., that things are constantly changing; the statement comes from Heraclitus.

Hili: Panta rhei.
A: What does that mean?
Hili: Time flies.
p1050158
In Polish:
Hili: Panta rhei.
Ja: To znaczy?
Hili: Czas leci.

New Chrome extension replaces pictures of Donald Trump with kittens

December 9, 2016 • 2:45 pm

According to Cheezburger’s Fail Blog, there’s a new extension for the Chrome browser that replaces pictures of Donald Trump with pictures of kittens. Here’s an example:

screen-shot-2016-12-09-at-2-34-33-pmYou can supposedly download the extension here, and 8 people have given it four stars. The rationale?:

screen-shot-2016-12-09-at-2-38-19-pm

Now I’m a bit wary of this. How does it identify pictures of Trump? What if it sometimes worked in reverse, replacing photos of kittens with photos of Trump? That would devastate me.  But if anybody wants to try it, and report back, I’d be delighted.  After all, my modus operandus for Facebook friends who posted endlessly about Trump was to add a cute kitten to the comments section.

Adam Fisher: The “diversity” trope neglects class

December 9, 2016 • 1:15 pm

Jacobin Magazine bills itself as a left-wing site with a socialist slant, so you can’t write off this piece, by Adam Fisher, as expressing the biases of a right-wing writer. I can’t find much about an “Adam Fisher” on the Internet, but that’s not surprising given his subject: his upbringing in a small and impoverished town in the Sierra Nevada foothills of California. His piece, “The blind spots of liberalism“, grew out of his hardscrabble upbringing, going to school in a trailer and coming home to a table devoid of food. The town, once engaged in mining and lumbering, was left behind when those industries petered out. In his town, people worried about one thing: where their next paycheck was coming from, or, if they were getting one, how long it would last.

Fisher uses this town as an emblem of the kind of people who voted for Trump, people who, he says, weren’t racists or sexists, but living in fear and poverty. A snippet (my emphasis):

Mine was the kind of town that a classless identity politics forgets. The kind of town where being male or white or Christian wasn’t synonymous with having decent housing, proper medical care, or a steady job.

Politicians are remarkably adept at pitting the economically disenfranchised against the racially or sexually marginalized.

Fear of hitting a glass ceiling is set against the fear of having one’s wages stolen. Fear of never being able to love the way one wants to love is set against the fear of losing one’s job and being out on the street.

At times, liberal forms of identity politics can fall into this trap. The reactionary that blames the plight of workers on the breakdown of traditional marriage and porous borders has more in common with the liberal pundit who blames racism and homophobia on the ignorance of white workers than either would like to admit.

But it was not white working-class people who drafted the Violent Crime Control and Law Enforcement Act that Bill Clinton signed into law in 1994. It was not struggling rural workers who sold this bill to the public by labeling young black men “super predators.”

The people in my small town did not own the private prisons that paid inmates $0.23 to 1.15 an hour, nor did they own the companies (like Whole Foods) that exploited prison labor. They were, however, hurt by the downward pressure that such labor schemes placed on workers’ wages.

Inevitably, the blind spots of classless identity politics benefit elites.

In one rarified area, the wage gap has apparently vanished: chief executive officers of America’s richest companies. But this means very little to, say, women in traditionally feminized occupations like nursing and home health care work. A $15 minimum wage would be a more significant win for feminism than gender parity for CEOs. 

Similarly, in my childhood town, glass ceilings and the shattering of them didn’t improve the lives of those just trying to pick themselves up off the floor.” The Yahoo CEO’s gender, or the US president’s race, had very little impact on the average citizen’s life. It wasn’t of much consequence to them if a prominent CNN anchor was gay, or if a black woman was a media mogul, or if a past Olympian had gender reassignment surgery.

However, it did matter if their standard of living was simultaneously decreasing and the precarity of their job was endangering their children’s future.

I had no idea that Whole Foods employed prison labor to make some of its products, but the link seems kosher, though the practice stopped in April of this year. But really, the sanctimonious Whole Foods?

In the rest of the article, Fisher doesn’t so much oppose identity politics as to say that class should be added as one “identity”. Indeed, if we’re going to consider those who are marginalized, then there’s a very good case that this should include the working class as a whole, regardless of pigmentation. As determinists, we know that such folks didn’t choose to be poor: the combination of their genes and environment made them wind up that way. Nor does this determinism mean they’re beyond help, because my own determined impulses are prompting me to convince you of Fisher’s thesis.

“Diversity” is now a euphemism for two things only: increasing the variance within a group in skin pigmentation and gender. And certainly everyone should, from birth, have the opportunity to succeed regardless of ethnicity or gender, though we have to make sure that all those opportunities are equal from the outset.

But how about the poor? Should they be preferentially recruited as college students, professors, or employees in general? Well, financial need is irrelevant for acceptance in some “need-blind” colleges, but those white students like Fisher, who went to a lousy school in a dirt-poor town, are disadvantaged from the beginning.  Should we have affirmative action for poor white people who, like many blacks, are disadvantaged in this way? If not, why not? Isn’t that also a kind of diversity we need? After all, the rich and poor are different from you and me.

Well, regardless of considerations about affirmative action, which is not Fisher’s focus, we need to realize that class may be just as important as race or gender in politics. We know this because it was class divides among Americans that led to the election of Donald Trump. Yes, you can say that those people were ignorant, not knowing where their real interests lay (and, given Trump’s cabinet, it seems likely they’ll eventually realize that), but they weren’t racist or sexist. They ignored the odious side of Trump (actually, the odious 99.5%), because for them Hillary Clinton symbolized someone who, while taking loads of dosh from Wall Street, would ignore their plight.

For those who write these people off as misogynist Nazis, here’s how Fisher finishes his piece:

Since I lived there, the population of my childhood town has nearly doubled, fueled in part by telecommuting and cash migrating from Silicon Valley. Median income has risen to $47,000, but the median home price fell 43 percent between 2003 and 2013. The school has moved to more appropriate permanent buildings.

This November, the town (and 362 other Placer County, California precincts not unlike it) voted for Donald Trump over Hillary Clinton, 51.1 percent to 39.5 percent.

But it’s hard to blame sexism or racism for Clinton’s loss.

On Election Day, the people of Placer County also voted for Kamala Harris, a black woman, to be their US senator. Her vote share? 63 percent. And her vote tally? 16,178 more than Clinton’s.

Somehow, as progressives (and mostly Democrats), we need to stop demonizing the working classes and find a platform that offers them substantive hope. And it’s not just to help elect someone like Clinton, either. It’s simply the right thing to do.

Guardian asks scientists to choose their best reads of the year

December 9, 2016 • 10:15 am

I’ve already mentioned somewhere that the New York Times‘s list of 2016’s 100 notable books had about 2 or 3 science books, and its shortened list of the 10 best books had no science books. Given the “two cultures”, one would expect more.

Our own Matthew Cobb noticed the same issue with the Guardian’s 110-best list (chosen by writers) , and tw**ted about it, showing that the proportion of science books was even lower than in the New York Times‘s list.

Well, the Guardian has taken steps to repair the situation, surveying 11 scientists and asking them what were their favorite reads of 2016 (“Favourite reads of 2016—as chosen by scientists“).

Here’s the intro to the Guardian piece, citing our already-famous Dr. Cobb and even showing his tw**t (click on screenshot to go to article):

screen-shot-2016-12-09-at-9-18-26-am

The books chosen weren’t all published this year, and they include both fiction and nonfiction, so they serve as a cross-section of what scientists are reading. Most of the books, though, are nonfiction, with most of these at least tangentially about science, but Joseph Conrad’s Typhoon is also there.

The upshot: as I always maintain, scientists who read have a much more balanced selection, at least with respect to the Two Cultures, than do nonscientists. In other words, scientists know a lot more about the products of the humanities than scholars of the humanities know about the products of science. This is a sad situation, for in many ways science is more thrilling than fiction—because it’s real—and because all of us academic scientists are teachers who want others to be stimulated by our fields.

Feathered dinosaur tail in amber!

December 9, 2016 • 8:40 am

In a market in Myanmar, the Chinese scientist Xing Lida, shown in the picture below, found a piece of amber about the size of a dried apricot, and it had an inclusion. The seller, thinking the inclusion was a piece of plant, raised the price, for biological items in amber dramatically increase its value. Still, Xing bought the piece at a relatively low price, for the seller didn’t realize that the inclusion was not a plant, but part of a theropod dinosaur! And so it was: part of the theropod’s tail, which was sprinkled with feathers. The specimen turned out to be from the mid-Cretaceous, about 99 million years old. It’s a remarkable piece:

The specimen: a bit of theropod dinosaur tail with very clear feathers
161208123535-dinosaur-amber-5-exlarge-169

That specimen tells us something about the nature and evolution of dinosaur feathers, which evolved long before the feathers were used for flight in the birds that evolved from theropods. The function of these feather rudiments still isn’t known, but they were likely to be for thermoregulation and could also have served as ornamentation. (Sexual selection is probably ruled out since there doesn’t seem to have been sexual dimorphism in the feathers.)

The paper, by Lida Xing et al. (reference below, along with link that may or may not allow you to get the full pdf), is the first to describe not only feathers in amber, but also mummified skin and skeleton.  It apparently belonged to a non-avian coelurosaur, the group of feathered dinosaurs from which birds are descended (not all paleontologists and ornithologists agree about that scenario, though most do). Based on the tail, the animal was very small: a CNN report on the finding says the specimen could fit in the palm of your hand, and was about the size of a sparrow. Can you imagine a dinosaur that small?

The remarkably preserved feathers were examined with phase-contrast X-ray scanning (right below), which showed a paired series of feathers along the midline of the dorsal (top) part of the tail (the bottom is sparsely feathered). Some color can be discerned, suggesting the dinosaur was white and chestnut brown, also like a sparrow. In B, below, you can see some of the vertebrae; there are eight full ones and part of a ninth—a remarkably large section of tail, and showing that the bird was indeed small. (All photo captions are from the original paper.)

(C) Caudal exposure of tail showing darker dorsal plumage (top), milky amber, and exposed carbon film around vertebrae (center). (D–H) Reconstructions focusing on dorsolateral, detailed dorsal, ventrolateral, detailed ventral, and detailed lateral aspects of tail, respectively. Arrowheads in (A) and (D) mark rachis of feather featured in Figure 4A. Asterisks in (A) and (C) indicate carbonized film (soft tissue) exposure. Arrows in (B) and (E)–(G) indicate shared landmark, plus bubbles exaggerating rachis dimensions; brackets in (G) and (H) delineate two vertebrae with clear transverse expansion and curvature of tail at articulation.

For reference: here are the parts of a modern bird feather; the important parts are the rachis, or main shaft, the barbs, branches off the shaft, and barbules, the smaller branches off the barbs bearing hooks that hold the barbules together—like Velcro—into a single apparatus.

This picture shows a series of rachis-like structures that splay out from a single place, and each of those is covered with branches, which the authors interpret as barbules:

(C) Dark dorsal feather in transmitted light, apex toward bottom of image. (D) Base of ventral feather (arrow) with weakly developed rachis. (E) Pigment distribution and microstructure of barbules in (C), with white lines pointing to pigmented regions of barbules. (F–H) Barbule structure variation and pigmentation, among barbs, and ‘rachis’ with rachidial barbules (near arrows); images from apical, mid-feather, and basal positions respectively. Scale bars, 1 mm in (A), 0.5 mm in (B)–(E), and 0.25 mm in (F)–(H). See also Figure S4.

Below is a close-up of the feather, which shows a “weakly-developed” rachis off of which ramify alternately-placed barbs, themselves bearing barbules.  According to the authors, this supports one of two alternative forms of feather development proposed by evolutionists, with both shown in the bottom part of the figure below. In one scenario (top), the barbs ramify from a developmental focus, then coming to branch directly opposite each other off a rachis, withe the barbules evolving later, becoming asymmetrical to form a flying surface.

The second scenario, which the authors say this specimen supports, is the development of barbules on the barbs before one of them (I think) evolves into a rachis with alternatingly-oriented barbs (that’s this specimen, circled in the figure as an intermediate). Then the barbs evolutionarily move to positions opposite each other on the rachis. Thus, this intermediate supports the bottom evolutionary scenario.

I have to admit that I’m not familiar with the controversy about feather development, and if there are facts to add here I’ll leave them to more knowledgable readers.

Barbules are omitted on upper side and on one barb section (near black arrow) to show rachidial barbules and structure; white arrow indicates follicle. (C) Evolutionary-developmental model and placement of new amber specimen. Brown denotes calamus, blue denotes barb ramus, red denotes barbule, and purple denotes rachis [as in 5, 12]. Scale bars, 1 mm in (A) and (B).
Finally,  you might say, “Well, this may not be the developmental pathway for modern bird feathers, but only for the lineage that contained this species.” But that’s unlikely since paleontologists and developmental biologists tell us that feathers evolved only once, so this specimen does have a bearing on feather evolution. (By the way, the supposedly unique evolution of human intelligence is often used by theologians to claim that that our intelligence, with the ability to apprehend the divine, must have itself been promoted by God. But feathers and elephant trunks are evolutionary one-offs, too! Could it be that God is a bird?)

Readers’ wildlife photos

December 9, 2016 • 7:30 am

Today we have an assortment of photos and videos from four readers. First, a video sent by Stephen Barnard on Monday:

A snow storm came through yesterday. I did a quick edit of some timelapse footage.

He asks us to “spot the mallards” in this video; click on the word “vimeo” at the lower right to go to the full-sized clip.

Reader David Fuqua sent duck photos with these notes:

Here are pictures of a Bufflehead duck (Bucephala albeola[top]) and a Ringed-Neck ducks (Aythya collaris [bottom]) taken recently in Arkansas, where they will winter. Both species are diving ducks.

Reader Simon Lawson sent a butterfly that’s hit on an ingenious form of camouflage:

Here’s another moth pic from Borneo.  This one is not as spectacularly pretty (or as large) as the Atlas moth I sent previously, but a favourite of mine nonetheless. It seems to have hit on a different solution to camouflage. No need to blend in by mimicking particular colors and patterns of tree trunks when all you need to do is make at least part of your wings translucent!  It looks slightly incongruous on the blue-painted house wall, but I suspect it would be hard to pick up on  a natural surface.  I have no idea what species this may be, but possibly a geometrid. [JAC: readers should weigh in below if they know.]

Finally, snakes from Garry VanGelderen in Ontario:

Since you are looking for more wildlife shots, I offer this one: garter snakes (Thamnophis sirtalis) peeking out from behind our brick facade. There is a bit of a gap between the bricks and the insulation. They like to hide there and come out when the sun warms the bricks.

Friday: Hili dialogue

December 9, 2016 • 6:30 am

Good morning on a chilly December 9 (Chicago temperatures -4°C, 25°F), with Arctic cold and snow approaching my town this weekend. It’s National Pastries Day, and I have one cupcake waiting for me at work (note added in proof: it’s now in my alimentary canal). There’s an unusual holiday in Sweden and Finland today; as Wikipedia notes: “Anna’s Day marks the day to start the preparation process of the lutefisk to be consumed on Christmas Eve, as well as a Swedish name day, celebrating all people named Anna.” I like the idea of name days (where’s “Jerry’s Day”?), and wonder if every day of the year is a name day in Sweden. But about that lutefisk: from what I know of it, I’d rather be named Anna than eat that lye-soaked pottage. Here’s a novice tasting the stuff for the first time; the best he can say is, “It’s not like I”m going to fall over and die.” Then he goes off camera and appears to vomit.

I mark with sadness yesterday’s death of John Glenn, war hero (in two wars), test pilot, astronaut, Senator  (he was the main author of the Nuclear Nonproliferation Act of 1978), ambassador for space, and, according to all save Tom Wolfe, a genuinely nice guy, never pulling rank. At the age of 77, he went up in space again, still approaching the adventure with childlike wonder.  When I was a kid I had an autographed photo of all 7 Mercury astronauts (unfortunately, that photo vanished), and he was the last to die.

On this day in 1905, France passed a law providing for the separation of church and state. And, exactly thirty years later, the first Heisman Trophy, for achievement in collegiate football, was awarded to Jay Berwanger of the University of Chicago Maroons. We’ll never see the likes of that again at my school; we have no athletic scholarships and a noncompetitive team. On December 9, 1961, Tanganyika gained independence from Britain, and, on this day in 1979, the final eradication of smallpox was proclaimed: a huge achievement for scientists, epidemiologists, and field workers. (No credit to prayer or religion here.) The disease has not reappeared, though frozen viruses reside, I believe, in two locations.

Notables born on this day include John Milton (1608), Margaret Hamilton (1902; you’ll know her as The Wicked Witch of the West in The Wizard of Oz), Kirk Douglas (1916; he’s 100 today, and still with us!), Judi Dench (1934), and Donny Osmond (1957). Those who died on this day include Edith Sitwell (1964) and Mary Leakey (1996), Meanwhile in Dobrzyn, while Cyrus goes after his ball, Hili pursues mice and birds, but Cyrus, ever protective of his little friend, warns her about predators of cats:

Hili: You can play with the ball and I will catch something.
A: Be careful not to get caught yourself.
p1050161
In Polish:
Hili: Wy bawcie się piłką, a ja sobie coś złapię
Ja: Uważaj, żeby ciebie nie złapali.

Finally, have two GIFs of foxes hunting for prey under the snow. They hear the rodent under several feet of snow, and, with the help of the earth’s magnetic field, dive on the (usually) right spot. Those pounces are generally toward the northeast; read about their remarkable snow-hunting ability here.
