Reminder: we’re playing Minecraft tomorrow at noon central time

I announced a group game on Sitosis the other day, and I have noticed a surge of enrollments on that server this week. Uh-oh. There might be a few problems.

  • There are rules for joining and playing on the server. Make sure you read them!
  • If you want to make a last-minute application to join, be kind to the admins, who have to individually approve each application. If you haven’t already joined, it’s probably too late to get in for tomorrow.
  • The server has a limit of 20 simultaneous log-ins. I didn’t think it possible we’d get that many users, but from the number of new users, we might. If we hit the limit, we’ll just have to do an additional session later this week.
  • If 20 people sign on before I do, well, the livestream will go on and it’ll just be me talking over a blank screen. Exciting!
  • We’ll use the Freethoughtblogs Discord server for voice chat. That might get interesting, with me trying to monitor that, the YouTube chat, and the game, all at the same time.

I have some trepidations that this might all disintegrate into total chaos. We’ll see how it goes. We like to experiment, right?

My mission for the day

I have received a mission request from iNaturalist. I have chosen to accept it. It did not self-destruct after I read it.

Records of Argiope aurantia (Yellow Garden Spider) and Argiope trifasciata (Banded Garden Spider) for 2020 started getting posted a couple of weeks ago. These two species are some of the most photographed spiders in Minnesota thanks to the female spider’s habit of sitting in her web in sunny locations like prairies and gardens. These species are easy to distinguish from one another and no other orb weavers match either their size or bold patterns.

Last fall the members of this project joined forces to find 13 new county records for Argiope aurantia and 12 new county records for Argiope trifasciata. But we still haven’t recorded these species in every county in Minnesota so I’m throwing down the gauntlet once again! Can we make these two species the first two spiders known from every one of Minnesota’s 87 counties?

The following 35 34 counties have no records of Argiope aurantia:
Aitkin, Beltrami, Big Stone, Carlton, Cass, Clearwater, Cook, Crow Wing, Grant, Houston, Hubbard, Itasca, Kanabec, Kittson, Koochiching, Lake, Lake of the Woods, Mahnomen, Marshall, Meeker, Mower, Murray, Nobles, Otter Tail, Pennington, Pine, Polk, Pope, Red Lake, Redwood, Roseau, St. Louis, Swift, Traverse, Wadena

The following 34 counties have no records of Argiope trifasciata:
Aitkin, Benton, Big Stone, Cass, Clearwater, Cook, Dodge, Fillmore, Freeborn, Goodhue, Hubbard, Itasca, Kanabec, Kandiyohi, Koochiching, Lake of the Woods, Mahnomen, Marshall, Martin, McLeod, Mille Lacs, Morrison, Murray, Norman, Pennington, Pope, Red Lake, Roseau, Sibley, Steele, Swift, Todd, Wadena, Wilkin

I’ll update this post as new county records get established. Happy spidering! (yeah, that’s a thing!)

You know what this means — ROAD TRIP! I noticed that West Central Minnesota counties are largely represented on the list. In my region, only Stevens (where UMM is), Douglas (where the larger city of Alexandria is), and Stearns (St Cloud) have had records for these species. Mary and I figure we can hit up 3 or 4 neighboring counties and make a small dent in that list today, and get out and explore at the same time. We might also squeeze in our local grocery run and have a picnic. We can’t lose!

We made a trial run last night, just here in Stevens county. We found lots of Argiope just in the grassy ditches that run alongside the highways around here, so this ought to be easy. If any of my fellow Minnesotans in more distant counties want to join in, please do.

If you don’t know what these spectacular spiders look like, I posted some photos on Patreon and Instagram.

Antici…pation

All baby spiders are now accounted for, but I may not be done yet. There are two more egg sacs awaiting the emergence of more hordes of spiders in the lab, and the only thing that might be sparing me right now is the temperature. The science building is at 18°C right now, which is cruel and wasteful, but it’s been that way all summer, I don’t know why. I have to go home now to thaw out — my fingers are just frigid. The rest of me is OK, because this is how I dress in the lab now, in August.

It’s nice to have an excuse to wear my spider sweater in the summer, but still…

Also the hat is necessary to control my pandemic hair, so I can’t blame that on the physical plant.

Wait, you didn’t want to see a picture of me, you wanted to see a sexy photo of a mama spider and her great big egg sac? OK, I put it on Patreon and Instagram. Trust me, the spider is beautiful and maternal, despite having to deal with an unusually chilly environment.

Spider Math

I have spent many hours today, counting spiders. I’m trying to keep track meticulously to figure out where the danger zone in spider raising is, and I don’t think I’ve reached it yet. I’m dealing with 3 clutches of spiders from 3 different mothers and 3 different fathers (they were caught in relatively different locations), and I’m simply tracking numbers right now.

Runestone line, 16 days old: 22 spiders, 96% survival, density of 1.1/vial.

Horticulture line, 15 days old: 94 spiders, 90% survival, density of 2.2/vial.

Myers line, 14 days old: 71 spiders, 93% survival, density of 3.0/vial.

There’s an accidental experiment in there. The first hatching from the R line was small and manageable, we were able to quickly and efficiently move them into vials, no sweat. They’re mostly living as single spiders in each vial.

The H line, on the other hand, just erupted with lots of spiderlings and we were a little overwhelmed and rushed. A fair number simply escaped, some we just gave up on and left in the cage with their mothers, and we were straining to get them all contained…so we had on average 2 per vial, and the max was 5 in a single vial.

The M line also taxed us, because I ran out of racks to store all these tubes. We tried to get as many as we could into the available slots, so there you go, on average 3 spiders per vial. I could at least look and see if the density in the first few weeks of mobility made a difference in survival.

And no, it doesn’t seem to. In fact, most of the deaths were in vials with single spiders, which makes me wonder if there might be some cooperative work in bringing down fruit flies, which are much bigger than the spiderlings. I did see, though, that big size disparities are emerging — some individuals were twice the size of their siblings in the same vial. I haven’t seen any sign of cannibalism yet, but that may arise if I don’t keep everyone well fed. Which reminds me, I’ve got 187 spiders down in the lab waiting for dinner.

I’d rather put something in the mail than sacrifice myself for Donald Trump

I don’t know who Josh Bernstein is, but he’d be fine with me dying. He compares voting in person to storming the beaches at Normandy and thinks we ought to be willing to do that. Sacrifice yourself for Donald Trump!

Some of these folks may actually get sick, and that’s sad, and it’s unfortunate, and I hope that it doesn’t happen, Bernstein continued. “And some of them, yes, they may even die and pass away. So be it. I don’t mean to be callous. I don’t mean to be cruel. I don’t mean to be insensitive. But we’re not asking you to storm the beaches of Normandy here, and we’re certainly not asking you to try to overtake Hamburger Hill either. We’re asking you to get out of the house and go down and vote for President Trump so that you can secure your children and your grandchildren’s future, to make sure that they live in the freedom that you have enjoyed as well. OK? Some people are going to die. So be it. It will be their last sacrifice for this country.

He might as well announce that “We must secure the existence of our people and a future for white children” by voting Republican.

Of course, military action in WWII was necessary to oppose a totalitarian force that threatened to invade us, and was killing its own citizens. If we had an alternative to D-Day that involved simply mailing some letters, I would have suggested we do that. We didn’t have that alternative, but we do have a way to vote that doesn’t require me to risk my life. I think we should do that, despite Bernstein’s paranoia about imaginary voter fraud.

Also, if I had to vote in person, it wouldn’t be for a Republican of any kind.

There goes Andrew Sullivan again

I’ve been living in Academyville most of my life, which means I’ve met some of the villainous ogres the right-wingers hate: Marxists and Post-Modernists. I’ve never met two of them at the same time, though. I’ve also met Fanatical Capitalists. It’s a real slumgullion in here, but that’s part of the charm.

Enter Andrew Sullivan. Or rather, exit Andrew Sullivan, who has left his comfortable paying job slinging dull resentment of things he doesn’t understand to put on rusty armor, climb aboard a tired donkey, and begin a crusade against…critical theory? Which again, he doesn’t understand, but is absolutely sure it is about destroying the very fabric of society.

I’m no expert in this stuff — I tinker with spiders — so I tend to defer to the experts on the other side of campus, you know, the social scientists and humanities people. Unlike the Sullivans of the world, I’ve mingled enough with them to respect their intelligence and knowledge, and to know that they are as sincere in their use of intellectual tools as I am in trying to understand the genes and processes behind spider development and behavior.

So I listen when someone like Asad Haider analyzes Sullivan’s claims.

After a grandiose announcement that he was leaving New York Magazine due to a stifling political atmosphere, Andrew Sullivan has now launched a comedy career. In a post of his new “non-conformist” newsletter, Sullivan announces that he will present an analysis of contemporary “social justice” politics. This politics, he says, is the development of “an esoteric, academic discipline called critical theory, which has gained extraordinary popularity in elite education in the past few decades.” Critical theory, he says with what can only be dry sarcasm, is so powerful and omnipresent that it is “changing the very words we speak and write and the very rationale of the institutions integral to liberal democracy.”

Sullivan’s account is full of falsehoods and misinterpretations so drastic that they could only be the product of a refined wit. The neologisms he attributes to the tradition founded by thinkers like Theodor Adorno are: “non-binary, toxic masculinity, white supremacy, traumatizing, queer, transphobia, whiteness, mansplaining.” One can only hope that Sullivan branches into sketch comedy, so we might see a dramatization of Adorno’s reaction to such terms. “The intellectual fight back against wokeness has now begun in earnest,” reads Sullivan’s deadpan conclusion. “Let’s do this.”

To appreciate this joke you have to understand that there’s a second, “meta” level to it, which is that Sullivan claims to be defending principles of ethical journalism, rationality, objective truth, and informed debate, but he never refers to a single primary text of what he calls critical theory. Twice as funny.

That’s what gets me. These bozos are dead set on the idea that critical theory is evil, but over and over again they reveal that they haven’t actually read anything in the field, and don’t even have a grasp of critical theory 101. I say “they” because it’s not just Sullivan — he has a whole clown car of buffoons joining him in the same futile enterprise.

In the midst of this comic tour de force we’re introduced to other characters, who give Sullivan a run for his money: James Lindsay, better known on Twitter as Conceptual James, and Helen Pluckrose, authors of Cynical Theories. Lindsay should be recognized for one of the most audacious comic bits of this whole contemporary discourse: in an ornate blog post which claims to clarify the distinctions between categories while actually muddling them beyond recognition, he writes that postmodernists “drew heavily off the successes of Mao in his Cultural Revolution and used them to inspire Pol-Pot, who studied alongside them at the Sorbonne in Paris at the time, to go after a deconstructive Year-Zero campaign of his own.”

He links to a blog post by Lindsay which is amazing. Lindsay throws out a dense cloud of terms that he misuses, revealing that he doesn’t know what he’s talking about, but apparently thinks vomiting up noise makes him sound informed. The closest thing I’ve seen to it are creationist posts that spew out a chaff of molecular biology to totally misrepresent what the papers actually say. Maybe he ought to read Haider’s article to clear up some of his misunderstandings.

It’s quite a long and thorough article that summarizes many of the terms they mess up. I’ll just quote the relevant bit about critical theory.

According to Sullivan, “postmodernism is a project to subvert the intellectual foundations of western culture,” for which “the entire concept of reason—whether the Enlightenment version or even the ancient Socratic understanding—is a myth designed to serve the interests of those in power, and therefore deserves to be undermined and ‘problematized’ reason [sic] whenever possible.”

But as Foucault clearly explains, critique is not a destruction of every form of reason but a putting into question of who we are, what we think, and what we do, by studying the histories that have produced us. It doesn’t simply mean finding fault with things, “criticizing” things. Though it may certainly involve that, this isn’t what the “critical” in critical theory or any kind of critical thinking refers to. The critical attitude continues, in fact, a certain attitude of the Enlightenment, while also situating the Enlightenment in the history which is to be approached with the critical attitude.

As Foucault traces in his 1978 lecture “What is Critique,” in Europe the critical attitude arises in the context of societies in which people and their thoughts are governed by religion, and it reflects the desire not to be governed — or at least, not to be governed quite like that. Critique is “the art of not being governed quite so much.” Hence the critical attitude of the Enlightenment is to not simply accept what an authority tells you is true, but to independently determine its validity; not to follow laws because they are dictated by power, but because you have determined them to be just. Critique, contrary to Sullivan’s paranoia, is an Enlightenment attitude.

That’s precisely what I don’t get. Skeptics ought to be enthusiastically embracing critical theory, and even post-modernism, because it does all the stuff skeptics claim to appreciate. Read that last paragraph again. Only a Status Quo Warrior would think that is undesirable. But instead they’ve only embraced the fringe abuses of theory, and have happily adopted only the practice of the worst writers to string gibberish into bad essays and books.

The spider struggle continues

13 days until classes begin, and this last batch of spiders are now about 13 days old. I took a few pictures (I stashed one on Patreon and Instagram) and had to struggle a bit with the photomicrography system, which I’ve mostly neglected this summer, on top of struggling with putting a lab demo together on video. Tomorrow is going to be busy feeding a few hundred spiders…well, maybe. Another thing I’ve noticed is that some of the babies have died, just out of natural mortality, I think, and tomorrow will involve counting the living and the dead, hoping the former outnumbers the latter.

Somewhere in here I’ve got to get my syllabi order, too.

North Paulding High is the epitome of professionalism!

North Paulding High in Georgia has opened, and there are swarms of students milling around maskless in crowded hallways. What to do about it? I know! Prohibit the publication of any photos that show how incompetently they’re managing the pandemic!

All those students ignoring the mask requirement? They’re fine. The student who posted that photo? Suspended! (It’s probably better for him, anyway). The administrators who permit that kind of crowding? Oh, they’re fine, no problem.

Would you believe there is already a COVID-19 outbreak among the football team, which held a practice the week before? You probably would. They opened anyway. The administration is incredibly slack.

Despite recommendations from CDC health officials, the district has called mask-wearing a “personal choice” and said that social distancing “will not be possible to enforce” in “most cases.” While the school provided teachers with face shields and masks and encouraged staff and students to wear them, they are not required and not all teachers have chosen to use them. One North Paulding teacher resigned last month over concerns about virus safety.

Jeeeezus. Just close all the schools already.

The Quack-in-Chief is dispensing dangerous medical advice again

When will Twitter and Facebook get around to banning this guy? Isn’t it bad enough that he has his sycophants at Fox News broadcasting his garbage everywhere?

Watch this excerpt (starting at around the 12 minute mark) in which Trump opines on why we need to open the schools, after a rant from one of the Fox & Friends morons declares that the threat of closing schools is political extortion.

Once again, we get Trump’s wishful thinking, this thing is going away it will go away like things go away, whatever that means. The numbers are going up, not down. He claimed that the virus would go away over the summer, because the sun would kill it; now he doesn’t seem to care that we’re heading into fall, and that we’re planning to pack people into classrooms again.

children are almost — and I would almost say definitely — almost immune from this disease…they have much stronger immune systems than we do somehow for this…they don’t have a problem, they just don’t have a problem. Jebus. No. They’re also at risk, but also kids aren’t isolated. Even if he were correct (he isn’t), doesn’t he see the problem with hundreds of thousands of asymptomatic disease carriers scurrying about, infecting parents and grandparents and teachers and random people they bounce off of? (Grandparents and teachers…this is getting personal for me.)

He claims I’ve watched some doctors say they’re totally immune. Name them. They need to be censured as badly as the President of the United States. Also, his magaphone, Fox News, needs to be smashed.

Mighty Huntress

I learned something today! There is this spider I keep on my office desk. I’ve always wondered, since these spiders are so passive and patient, and I’m feeding them wingless Drosophila, do they just wait until one stumbles into their web, or do they ever actively hunt? The answer is…they’ll hunt when opportunity arises.

So this spider has webs strung across this wooden frame, and she tends to hang out near the top of one of the sticks.

This afternoon I watched her abruptly descend on a drag line from her perch to the gravelly scree directly below to drop on a fruit fly walking by, bite to kill, and wrap it in silk before hauling it right back to her starting point. It was spectacular!

In case you’re squeamish about this sort of thing, I’ve put a closeup of the proud hunter below the fold.
