“There’s so much messaging in general about STEM, STEM, STEM”

“As STEM majors soar at UW, interest in humanities shrinks — a potentially costly loss” (Seattle Times) is kind of interesting.

The liberal-arts decline is making the university financially poorer, too.

That’s because it’s cheaper to teach a history class than a computer-science course — but the UW charges the same for both. In effect, the humanities courses have always subsidized engineering, natural sciences and computer-science classes, said Sarah Hall, vice provost of UW planning and budgeting.

Nationally, it costs an $410 per credit hour to teach electrical engineering, one of the most expensive majors. Sociology, one of the cheapest-to-teach subjects, costs less than half of that — about $176 per credit hour.

Should people go to college in order to be happy or in order to earn enough money to pay back student loans and compensate for four years out of the workforce? Humanities professors have the answer!

Humanities professors disagree. They say it’s a myth that humanities majors can’t find jobs, and it’s disappointing that so many people are discouraged from pursuing their passions.

“What’s sad for the younger generation is that so many students here have been literally pushed away from the social sciences and humanities to STEM, and are not happy,” said UW history professor James Gregory.

“There’s so much messaging in general about STEM, STEM, STEM,” he said.

The innumeracy displayed by journalists and editors is interesting. The Seattle Times:

The stereotype that English majors wind up as highly educated baristas isn’t borne out by research, Stacey said. A recent study showed that many English majors are more likely to become teachers, lawyers, CEOs and legislators.

So they’re saying that if “many” out of thousands get good jobs then English is plainly a good vocational choice. The link-to article is even more interesting:

According to the Census Bureau, graduates with an English degree have about a 4.9 percent chance of working in one of these food service occupations for some time between the ages of 22 and 26. By comparison, the average among all degree holders in this age group is about 3.5 percent. So English majors are only about 1.4 percentage points more likely to work in food service than the average for all degree holders.

Wouldn’t it be a 40 percent increase to go from 3.5 to 4.9, not a 1.4 percent increase? And that’s across all degree holders, not measured against STEM graduates. Considering how many degrees are irrelevant to employers, a 40 percent greater likelihood of becoming a burger-flipper is huge!

  • “Two big questions for economists today”: Justine Hastings, of Brown University, presented “Earnings, Incentives and Student Loan Design: The Case of Chile.” It seems that Chile did what the U.S. did, i.e., offered a lot of student loans for higher education. Their program was more intelligently designed, however, in that they didn’t allow universities to raise tuition in response to this new source of funds. Schools ended up with more students, but not more money per student as has been prevalent in the U.S. Nonetheless, the default rate has been high, especially for graduates of non-selective schools and especially for those who majored in humanities and arts. Unlike Americans, Chileans don’t like to keep flushing cash down the toilet, so now they are experimenting with adjusting the maximum loan amount according to the expected return to getting a particular degree (in Chile you don’t apply to “University of Santiago” you apply for a specific major). It turns out that when students see that the government won’t lend them the maximum for a particular degree program they get the message and try to switch into a degree that will result in higher post-graduate earnings. This is especially true for “low SES” students. SES? Due to the rejection of Marx, mainstream economists apparently can’t talk about class so they refer to “Socioeconomic status“. Hastings has a separate paper “The Labor Market Returns to Colleges and Majors: Evidence from Chile” with the discouraging result that attending a lower quality college and majoring in poetry will not set the country’s employers on fire and, in fact, many people would have higher lifetime earnings if they refrained from attending college.

Surrounded by attractive college women at the gym…

A friend in his 30s works out every morning at a Planet Fitness. Our conversation:

Him: At least 25 percent of the customers at that time of day are attractive women from [adjacent university].

Me: Why don’t they work out for free at their school’s gym?

Him: I don’t know.

Me: Haven’t you talked to them? Have you ever been out on a date with one and asked her why she subscribes to this commercial gym?

Him: I’ve never asked one on a date.

Me: You’re a real gentleman!

Him: It would be too much work. With Tinder and Bumble, I can [be in bed with a woman] an hour after opening the app.

(I’m sticking with my gym. It costs a lot more than the $10/month that he pays, but we are not weight-shamed by fit 20-year-olds.)

El Chapo’s Temporary Flight Restriction

Before a recent night flight from Hanscom Field (KBED) to Land of Gulfstreams (Teterboro, NJ; KTEB), I decided to call the official government-sponsored weather briefer at Leidos. The KTEB folks were shutting down one runway and I wanted to make sure that I hadn’t missed anything else important.

The briefer asked “You’re familiar with El Chapo’s TFR in Brooklyn?” I hadn’t heard about it, but it seems that El Chapo is being protected by a temporary flight restriction centered on the courthouse, with a radius of 0.4 miles, and from the surface up to 1,500′. The user-friendly page doesn’t mention El Chapo, but the XML text does:

Separately, let me say thanks to the good folks at Meridian TEB. It is a bad day for any FBO when a piston-powered aircraft shows up and that’s especially true at Teterboro (do you want to sell 15 gallons of 100LL to Joe CFI in the flight school Cessna or 2000 gallons of jet fuel to Gulfstream Al (Gore) or the Clinton Foundation?). Meridian has always been friendly and helpful, even keeping midget chocks around for those of us who fly Cirrus or similar. This was a business trip and my departure was set for Official Polar Vortex Panic Day. It was 3 degrees overnight on the ramp and warmed up only to about 12 by mid-day. Starting an aluminum aircraft engine after it has been cold-soaked does a lot of damage. Meridian kept the plane in their warm maintenance hangar overnight and until our 2 pm departure. It is ground-support folks like this that make personal aviation practical in the U.S.

Finally, now that the shutdown is over, our local government workers are working 24/7. Email received today:

Please be advised that the Bedford Air Traffic Control tower will provide ATC services during the overnight hours 2300-0700, this Sunday night, after the Super Bowl.

Additional Airport Operations staff will be on hand to support the increased aircraft arrivals.

(usually the tower is closed from 11 pm to 7 am)

Middle class Californians subsidize wealthy Tesla owners, 2019 edition

“I got an electric car. My electric bill went down” by Brad Templeton is worth reading. He summarized it on Facebook:

Surprise: I got an electric car and my power bill went DOWN. Why? When you get an electric car in California, it allows you to switch to a heavy “time of use” power plan with expensive power in the peak (2pm-9pm) and much cheaper power in the night. I charge my car at night and moved my pool pump to the night so the net was my bill went down — my electric car gets almost “free” electricity, it seems. YMMV.

One angle he doesn’t cover is that the guy who could afford to purchase a new Tesla is being further subsidized by people who can’t afford to purchase a new Tesla (or any other new car!).

Fahrenheit 11/9

Michael Moore’s Fahrenheit 11/9 is streaming on Amazon Prime right now.

It’s worth watching, even if you don’t advocate for abandoning capitalism in favor of socialism, as Mr. Moore does.

The first section is about the 2016 election. Moore says that Trump didn’t want to run for president, but only staged a couple of fake rallies to show NBC that he should be paid more. Only when Trump saw how voters loved him did he decide to run in earnest. The presentation of footage from the respective campaigns on the night of the election is dramatic even though we know the outcome.

The next section is about the incompetence, insincerity, and mendacity of establishment Democrats, including Hillary Clinton and the officials who suppressed votes for beloved Bernie Sanders at the convention, even from states that Mr. Sanders had won (but what difference would it have made? Hillary did win more votes).

Moore doesn’t waste too much time trashing establishment Republicans, whom his audience presumably already associate with being on the payroll of the rich. In fact, he says that, starting with Bill Clinton, most Democrats are also on this payroll and there is little to distinguish non-socialist Democrats from Republicans.

Moore covers the Flint, Michigan water situation in detail (it was all caused by Republicans and cronies who wanted to make big $$; simple incompetence was not a factor), but the relevance to Donald Trump is never clear. Everything significant happened prior to Trump taking office (though Trump was the only candidate from either party to visit Flint during the campaign, according to Moore). There is footage of Obama lying to citizens about drinking the water. He is shown asking for a glass and just wetting his lips with the potentially tainted water, but not sipping any. Hidden below the podium is a glass of the actual water that he is consuming.

Another theme that keeps coming up is the Parkland shooting, but Donald Trump’s involvement is not explained.

There is a lot of footage of Adolf Hitler. Trump’s voice is synced up with Hitler’s lips moving. (Those who are passionate about women in aviation will be disappointed that Hannah Reitsch isn’t shown or quoted (“It was the blackest day when we could not die at our Führer’s side.”))

Yale History professor Timothy Snyder is quoted saying that the comparison of Trump to Hitler isn’t perfect, but only because no comparison ever is. A 99-year-old Nuremberg prosecutor is interviewed saying that what Trump is doing by separating children from migrant parents at the border is as bad as the crimes he was prosecuting, e.g., killing 90,000 Jews. (Michael Moore has experience with U.S. family court litigation, but not a custody lawsuit that separated a child from a parent. All of the fighting has been over cash and real estate. The litigation has stretched over most of this decade and a new lawsuit was filed a few months ago (Daily Mail).)

The Reichstag fire is compared to 9/11 in terms of providing the would-be dictator an excuse to seize power, but it is unclear how Trump could have engineered an emergency 15+ years prior to taking office.

Moore and Professor Snyder seem pretty sure that Trump is on track to be the next Hitler, but they don’t say how it can be accomplished.

I had never seen Alexandria Ocasio-Cortez on video before (we are not TV news watchers), so it was interesting to see footage of her campaigning. Moore expresses enthusiasm about young female socialists, preferably immigrants and/or Muslim, taking over the Democratic Party.

The documentary footage closes with the Hawaii mistaken missile alert (all done by state officials in a state that last voted for a Republican in 1984) and with a student from Parkland speaking dramatically about the school shooting (but, again, why is Trump to blame for these unfortunate events?).

So Fahrenheit 11/9 is worth seeing both for how Michael Moore weaves together familiar topics and also to try to understand how young Americans who call themselves “socialist” think.

Want to know what a test pilot actually does?

If you want to know what a test pilot actually does, explained in a way that is technical and precise yet comprehensible and clear to non-experts, let me recommend watching Day 3 – PM session from http://web.mit.edu/webcast/16.687/iap2019/

(Diogo Castilho, an F-16 pilot from the Brazilian Air Force who is finishing his Ph.D. in aero/astro at MIT, talks about a couple of flight test programs)

Can any migrant from an Islamic country obtain citizenship in a Western country by saying “I renounce Islam”?

“Saudi teen lands in Canada after fleeing family” (CNN):

A Saudi teen who fled to Thailand to escape her allegedly abusive family has arrived in Canada after being offered asylum there. … Qunun had flown to Thailand from Kuwait to escape her family, saying she feared they would kill her because she renounced Islam.

Could this work for anyone willing to say to a Western official “I don’t think that there is a God”?

The U.S., Canada, Australia, or the European nations are required to offer asylum to anyone with a reasonable fear of persecution, right?

A lot of countries do not allow residents to commit blasphemy or apostasy. See Wikipedia on Freedom of Religion in Saudi Arabia, for example, or this page on how anyone who questions a major religion can be imprisoned for five years in Indonesia. Why couldn’t any of the 264 million folks who live in Indonesia move to Canada or the U.S. tomorrow, saying “I question the truth of all six recognized religions and I could be imprisoned for this if I were to be returned to Indonesia.”? How could a government official in Canada, for example, ever prove that such a declaration of disbelief was false?

Why would anyone from a country in which denying the truth of Islam is punishable bother with any other strategy for obtaining legal residency in a Western welfare state?

Gillette versus Dorco Shaving Test 3

Continuing research … (see Test 1 and Test 2)

Test 3:

  • one day of growth
  • shaving in the shower
  • Edge shaving gel
  • Dorco Pace 7 on right side of face
  • latest and greatest Gillette Fusion 5 ProShield with Flexball on left side of face
  • third shave for each cartridge

Results: More or less equivalent.

Still to try: Dorco Pace 6 Plus ($6.50 for handle and two cartridges; free shipping and no sales tax collected for MA residents). This one has a single trimmer blade in addition to its 6 regular blades, so it is more directly comparable to the Gillette product.

Related:

  • a 2014 review of the Dorco Pace 6 by a serious shaver-experimenter. He concludes that the Dorco product “is comparable to the Gillette Fusion Proglide” (but he had only 6 blades, not 7, at the time!) and that the Dorco cartridge is good for 20 shaves before requiring stropping (i.e., being thrown away, since a new one is less than $2).

Flying above 5,000′ cabin altitude

In our FAA ground school I had to show students a slide reminding them that FAR 91.211 requires oxygen for a pilot exposed to cabin altitudes above 14,000′ (and when flying between 12,500′ and 14,000′ after  30 minutes). They’ll be tested on that. From experience, however, I know that I feel more alert if I keep the (typically shorter) Cirrus flights to 7,500′ and the (sometimes long) Pilatus PC-12 flights to cabin altitude of no more than 5,000′.

“A Medical Look at Hypoxia” by Kevin Ware, a physician and ATP/CFI is an interesting article from a recent Twin&Turbine. The doc/pilot notes that the narrowing of arteries that comes with aging (and an American diet!) makes it tougher for the brain to get sufficient oxygen when starved due to altitude:

In summary, when a pressurized piston or turboprop aircraft is in the high 20 flight levels and operating just as it was designed (cabin altitude of 10,000–12,000 feet), the pilot’s body is only being supplied with half the oxygen available at sea level. This, in turn, triggers the Bohr effect, further decreasing the amount of oxygen available to the brain and heart, which if the pilot is of mature age, are already compromised due to the narrowing of blood vessels. … Given this physiologic reality, is it really safe for pilots with grey hair and some common health issues such as elevated cholesterol, high blood pressure, and possible arterial narrowing, to operate pressurized aircraft at their highest legal altitudes with cabin altitudes? The answer is probably not. But, if the pilot is willing, some steps can be taken to lower the physiologic risk to a more acceptable level, and it involves the use of supplemental oxygen.

Supplemental oxygen is something that needs to be used before hypoxia is present because its effect on the brain is very insidious and makes such recognition of what is occurring, and the logical solutions that would follow, nearly impossible. The best solution to recognizing the gradual onset of hypoxia is to wear a pulse oximeter anytime the cabin altitude is above 5,000 feet and watch the numbers on the dial.

Worth a read if you’re trying to decide if it makes sense to climb up another
4,000′ in a turboprop to save 15 gallons of fuel. Also if you’re trying to decide on whether to pay up for a pressurized plane or rely on supplemental oxygen. The author of this article implies that the typical buyer of a high-performance turbocharged, but not pressurized, piston airplane should be breathing supplemental oxygen for 95 percent of the flights.
