The laziest professor in the world!

That’s me! Today was our last day of classes, and rather than me doing the work of teaching, I invited Ken Miller to do it for me over Google.

I should have thought of this months ago — let’s see, 15 weeks, 3 classes a week, I could probably find 45 friends willing to cover for me for a day each.

Has anyone ever seen a good science stock photo?

I was once drafted to be an extra in a commercial for the University of Oregon. First thing they did was hand me a white lab coat. Second thing was to complain that they’d looked around the lab they were filming in, and couldn’t find any colored solutions in the refrigerator — could I get them some? I at least managed to stop them before they started mixing up random reagents from the shelves.

Public misconceptions about how science is done are terrible. How terrible? Here’s a whole collection of terrible stock photos. This one was my favorite.

There are a lot of botanists in my department. I should ask them if they have a stethoscope.

David Berlinski crawls out of his spider hole to sneer at science

David Berlinski! Now there’s a name I haven’t heard in a while. He appeared on Fox News last night, with his standard air of disaffected ennui to explain science to Mark Levin. It was a series of own goals.

He has little regard for science — they’re all shallow thinkers. That’s why they’re all atheists, who regard 5,000 year old religious traditions with contempt. He explains what he knows about the academy, which isn’t much, and portrays us all as people who go around sneering at religion. Well, I do…but I’m not at all representative. If I were to interrupt a committee meeting with complaints about the pervasive religiosity of the community I live in, that would be discouraged — we’re supposed to be reality-based, so the question would be about how we can adapt to the reality of our situation, how can we get along with our neighbors, and generally getting specific about our opinions on religion while carrying on our academic business is considered a faux pas. That goes for someone promoting a religion as well as for someone promoting no religion.

Berlinski then accuses scientists, and especially atheist scientists, of being shallow thinkers. That, I think, is generally true of everyone: we work in our little niche, and sometimes some of us poke our heads out and try to explore other ideas more broadly, but we each have our domains of expertise and tend to focus on those. But Berlinski goes further, and wants to proclaim the facts of science as inadequate because they aren’t wrapped up in enough philosophical baggage. For example, he says that the hypothesis that we are nothing but cosmic accidents has been widely accepted by the scientific community, and that is true — people have been looking for a teleological cause for centuries, and failing, while stochastic explanations for physics, chemistry, and biology have been succeeding wonderfully. In the absence of a cosmic plan, we have to accept that we are cosmic accidents.

I think that has significant social and moral and psychological explanations that ought to be explored further. Most scientists don’t worry about it; their job is to accurately describe reality, now let others figure out what it means. That’s not shallowness — science requires a great depth of knowledge — but only specialization. The thing is, if you’re going to claim scientists haven’t done a great job of fitting their answers to the greater puzzle of culture, neither have those advocates for 5,000 year old religious traditions. And the religious advocates have a more challenging job of propping up ideas that are demonstrably wrong and fly in the face of the observed facts.

Berlinski also can’t avoid elitism and lying about the science. Levin makes a mind-bogglingly stupid comment about climate change: they can’t tell us the temperature next week within ten degrees but they can tell us within a degree what it will be in a century, which is a goofy way of confusing local weather with global climate. Berlinski has a unique way of addressing the evidence of climate change: well, the “top physicists” aren’t studying climate change. Berlinski dismisses studies of the climate with I’m talking about top physicists, to get to climate change we all have to go down that ladder all the way down to the bottom. Then he claims that all those petty little substandard physicists who call themselves climatologists are all squabbling with one another with inconsistent results.

Then he gets to what Levin calls “Darwinianism”.

Here’s Berlinski’s arguments: he invents a series of just-so stories. Why did the giraffe develop a long neck? Because he wanted to reach leaves at the top of the trees. (That, by the way, is no element of any modern evolutionary explanation — he seems to be reaching back to vague memories from grade school of 18th century explanations). Why aren’t women born with tails like cats? Women don’t seem to need them, even though it would make them more alluring. He expresses every bit of biological diversity as a matter of whim and personal preference. He explains the problem: the anecdotes pile on interminably, and there’s no fundamental leading principle. Oh, nonsense. Berlinski invents anecdotes, and then uses his ignorance of the mathematical principles underlying, for example, population genetics to claim that population geneticists are just sitting around inventing myths.

He’s an annoying and pretentious kind of fool. He needs to fly back to France and disappear again, because he’s too out of touch to be able to contribute anything to any discussion except for his cultivated air of superciliousness. Which, I will admit, he has honed to razor sharpness. Too bad there’s no substance at all behind it, and that he is such a shallow thinker.

Any serial killers/rapists in my family?

I should warn you: I’ve submitted DNA samples to both the National Genographic project and to 23andMe. As we’ve just learned, that means the police can use that data to connect DNA samples collected at crime scenes to my relatives, which means they have a lead to you even if you haven’t given a DNA sample. Honestly, if I do have any criminals in the family, I would kind of hope they could stop you with that information.

However, I don’t remember giving the police permission to use my genetic information — it was probably buried in tiny print somewhere in an agreement I signed. That’s a bit troubling. OK, a lot troubling. Now I’m wondering who else has access. So, if there’s a disease-associated trait somewhere in my background, are the insurance companies going to knock on the door of my second cousins somewhere and announce that they now have grounds to suspect that there is a medical problem lurking in their genome, and they’d better cough up some increased rates?

Rachel Carson vs. Men of Industry

The New Yorker has a wonderful story about Rachel Carson which points out that we ignore most of her writing. She’s most famous for Silent Spring, which of course I’ve read, but much of her prior work was about the sea and the shore, which I have not. I guess I’m going to have correct that deficiency.

It also fills in many biographical details about her life, which was full of family responsibilities and struggles. My respect for her keeps going up and up.

I have to highlight one detail, though. After Silent Spring, this quiet, private woman who was dying of cancer (and refused to mention it in public), was savagely targeted for harassment by the American chemical industry. Remember this if anyone tries to tell you that science is not political.

“What she wrote started a national quarrel,” “CBS Reports” announced in a one-hour special, “The Silent Spring of Rachel Carson,” in which footage of Carson was intercut with footage of government and industry spokesmen, to create a de-facto debate. (Carson refused to make any other television appearance.) In the program, Carson sits on the porch of her white-railed house in Maine, wearing a skirt and cardigan; the chief spokesman for the insecticide industry, Robert White-Stevens, of American Cyanamid, wears thick black-framed glasses and a white coat, standing in a chemistry lab, surrounded by beakers and Bunsen burners.

Whoa. Caricature much? White coats & beakers, the trappings of scientism. I am amused, and appalled.

White-Stevens questions Carson’s expertise: “The major claims of Miss Rachel Carson’s book, ‘Silent Spring,’ are gross distortions of the actual fact, completely unsupported by scientific experimental evidence and general practical experience in the field.”

Carson feigns perplexity: “Can anyone believe it is possible to lay down such a barrage of poisons on the surface of the earth without making it unfit for all life?”

White-Stevens fumes: “Miss Carson maintains that the balance of nature is a major force in the survival of man, whereas the modern chemist, the modern biologist and scientist believes that man is steadily controlling nature.”

Stop right there. White-Stevens is simply wrong — that is a horrifying attitude to take, that rather than existing as a part of nature, humans are responsible for controlling nature. I can’t imagine any modern biologist taking White-Stevens position, in part thanks to Rachel Carson.

You can now watch the whole 1963 program, thanks to the intertubes. It’s not a pleasant experience: there’s a train of expressionless, somber white men all positively asserting that all of the chemicals they’re spraying across the landscape are harmless, that they have been thoroughly tested and do no harm to people at all, which is not particularly reassuring coming from people who think all of nature is to be brought under their control.

Watch for the scene where White-Stevens is lecturing at a lectern, and the camera pans to the audience…which consists entirely of men in crewcuts, white shirts, and/or ties. There are also scenes where the defenders have to reluctantly admit that widespread pesticide use sometimes damages the environment — they talk of streams full of dead fish, and one says that he’s seen the elimination of 80% of the wildlife in some areas. Watch the whole thing and it gets more and more clear that the overuse of pesticides has led to serious effects on animals at concentrations far lower than the industry endorses. White-Stevens does not come out of this looking good.

Rachel Carson, on the other hand, is magnificent. She doesn’t get enough air time.

Note that this was all before the EPA was established, which the current administration is trying to destroy.

Us Soy Boys should be relieved

It’s an odd thing how some people are scrabbling to invent markers for maleness, as if it is the sole defining feature of their existence, and yet must be constantly validated with sciencey affirmations of invisible phenomena. So we get statements about the utter certainty of the Y chromosome being the definitive factor in being male, from hordes of people who’ve never seen their own karyotype, some small fraction of whom might well have curious chromosomal abnormalities. Will it change who they are if a variation is found? No, not at all. We live in a fairly modest culture, too, and yet we want to declare possession of a penis to be the one great truth behind masculinity…yet I’ve never seen any of your penises, nor have you seen mine. We make demeaning jokes about small penises, but we don’t actually inspect them.

There’s another invisible attribute I’m seeing touted as important to your masculinity: testosterone levels. I’ve seen the silly commercials that try to sell supplements to correct that bane of men’s lives, Low T.

Well, that’s blatant. I better buy me a case of them there pills, lest I suffer the pity of a woman.

The thing is, most of us don’t know what our testosterone levels are. I get twice yearly checkups and get tapped for buckets of blood, and I’ve got reports on levels of triglycerides, HDLs, LDLs, CPK, all that important stuff that matters if you’re concerned about heart disease, but darn, they never bother to check my T levels, and I always forget to ask. Except for certain serious extremes, T levels don’t matter that much, and they certainly aren’t a major factor in that indefinable thing called “manliness”. I also note that half the population seems to function just fine with incredibly low T levels.

But now you’ve got shady companies trying to sell you supplements, and to them it’s really important that you consider T levels vital. The latest round of silliness from the alt-right has them accusing SJWs of being “soy boys”, that consuming products containing soy reduces their T levels. They don’t know! Testosterone levels vary within populations, to no obvious discernible effect, so it amounts to one group of people sneering at another group of people over their blood chemistry in complete ignorance of what it actually is. I feel like the only rational response in such an argument is to whip out a rubber strap and a syringe with a wicked sharp 21-gauge needle and offer to take a sample.

Or, I suppose, we could just have some medical professionals do a clinical assessment of the effects of testosterone. Oh? It’s been done?

So researchers set about designing the Testosterone Trials: double-blind, randomized, placebo-controlled clinical trials—the gold standard in medicine. They went looking for thousands of men over 65 with low T and at least one of its supposed symptoms. When the first findings came out in February 2016, one thing stood out from the start: Of the more than 51,000 men who had been screened, fewer than 15 percent had testosterone levels low enough to be enrolled, even after the researchers relaxed their testosterone threshold. The widely held idea that low T is rife among older men seemed to be a myth.

All told, the studies found that T did not improve men’s physical function or vitality. Nor did it help with age-related memory impairment. It did help with anemia and bone mineral density. It increased sexual desire and activity, but the effect was modest; men were better off using Cialis or Viagra. The most worrisome findings came from a study on cardiovascular risk: In men with certain risk factors, T accelerated coronary atherosclerosis, possibly increasing their chance of heart attack.

If you want to argue with this, I’m going to accuse you of having low aldosterone levels. Or was it cholecystokinin? One of those things neither of us ever bother to actually measure, anyway.
