The NTSB is investigating a “close call” between an Alaska Airlines 737 and FedEx 777 in Newark. The flights were on approach to intersecting runways when ATC instructed Alaska to go around. The 737 climbed, passing over the FedEx aircraft on the runway. flightradar24.com/blog/aviation-…

@arthur_spirling For burying power lines to make economic sense, you either have to have very high density (and in NYC they are mostly buried) or very high cross-subsidies (there is no way a village in N Europe could afford to if they had to pay themselves).
English
I’m a broken record on this but as an immigrant from N Europe, one of the weirdest things in the US is that power lines aren’t buried. This is true even in relatively dense places like central NJ. I need to understand more about the political economy of why this isn’t done

@Smartymarty66 @HannahWardEdu Uh wut? I’m a research scientist and I regularly consult books over 30 years old.
English
@HannahWardEdu Can I say, as a librarian, this means nothing.
I'm a librarian with access to millions of physical books and an extended digital library. As a result my home library is small.
Also any general scienc book over 10 yrs is out of date and useless.
This is a fake conceit.
English
How does your home library stack up? In 2023 YouGov surveyed 29,000 Americans to see how many books they have in their homes. The results were disappointing to say the least.
- 0 books: 9% (no books AT ALL)
- 1–10 books: 20%
- 11–25 books: 14%
- 26–50 books: 13%
- 51–100 books: 12%
- 101–200 books: 10%
- 201–500 books: 7%
- 501–1,000 books: 4%
- More than 1,000 books: 3%

This single-stair 6-plex is incredible.
We should do whatever it takes to make it possible to build 100,000 of these across California:

This project in Oakland is a pretty good model of the future of homeownership in urban California. In 10 years time, you're going to see condo buildings like these all over Los Angeles.

If “SS reform” means discontinue the program but pay out for the people who paid in according to approximately the current formula, fine. But if it means screw over those who paid in, no way. That’s about keeping promises we encouraged people to plan around, not rewarding irresponsibility.

"In contrast, no one fails to save for his retirement because of a few minutes of teen-age passion. To fail to save for your retirement, you need to make the wrong decision week after week, year after year. If you’re too immature to save for your retirement in your twenties, you have a second chance in your thirties, a third chance in your forties, and so on. In short, to fail to save for your retirement, you have to be consistently irresponsible for decades."

@PeterMoskos I have yet to see a US city try European-style bike paths. In most places in Europe they are on sidewalks or are entirely separate from both streets and sidewalks. US just paints another lane on a major arterial and calls it a bike path.

As somebody who used to take tourists in Amsterdam out on small boats, this hits home. If I had a dollar for every time I told an anti-urban American who "just loved" Amsterdam that we could have this too, if we chose to.

@JeremyLNeufeld @AlecStapp @InnovateEconomy @m_clem Even if it were iron-clad proved that no H1B was paid less than the comparable American, H1Bs would reduce wages. If more providers enter a market, the price decreases.
English
There’s a big ongoing debate about how much H-1Bs are paid compared to Americans that I think misses something really important.
Borjas says the wage gap is large and negative (-14%), @InnovateEconomy says it’s small and negative (-5%) and @m_clem's new paper says it’s not statistically significant (-1%).
But if H-1Bs were working as intended, shouldn’t the wage gap be large and positive?
The "Prevailing Wage" system is intended to block ANY H-1Bs with a negative gap. It's clearly not doing its job. Even in the most optimistic paper of this debate, roughly half of H-1Bs get approved despite a negative wage gap.
The Department of Labor just finished preparing a rule revising the Prevailing Wage regs, set to be published in Federal Register any day now. The admin has a huge opportunity here to fix the Prevailing Wage system:
Simply calculate the individual's wage gap and deny their H-1B if they are negative.
It would accomplish what Congress actually wanted Prevailing Wage requirements to do: prevent companies from undercutting Americans and reserve visas for those foreign workers who have truly rare and valuable skills.

What an amazing story, which really does capture the up and down feelings of cancer treatment.
One example of my own: they hadn't yet realized they needed to ask about COVID boosters before PET scans, so I went a few days with a result basically saying, "this is it."

@CoreyWriting We can solve this problem by expelling, suspending, and jailing a lot more problem kids.
English
One of the biggest reasons people don't want to be teachers is that they don't want to deal with kids. Being a high school teacher oftentimes means dealing with mean, aggressive, uncooperative minors everyday.
Kelsey Piper@KelseyTuoc
I think a society serious about improving education would think hard about this. high school teaching pays way more than adjuncthood already, it's just low-status and means giving up on dreams of academia. you could do high school positions that allow research half-time.
English
part of my skepticism stems from the fact that we have one party that is open to redistribution but cartoonishly incompetent at winning and another that is presently ensnared in a personality cult but even in the best of circumstances constantly seeking to cut welfare programs
Dr. 🐯PattyCatty🦁Stokes😸@Kittywampus
@jessesingal There is no earthly reason to believe that any surplus will be distributed. Surplus is what we more commonly call profit, and it goes mostly into the pockets of people like Elon Musk. Trump‘s tax breaks for billionaires show that redistribution is occurring—but upward.

@SashaGusevPosts Having teacher training does not make you a good teacher. Is there any solid evidence it even helps?
English
Two main issues with this: (1) having a PhD alone does not make one a good teacher (you need teacher training); (2) having free time alone does not make for pleasant research (you need colleagues/collaborators, seminars, trainees, etc).

@mark_bauerlein Suppose I have a humanities PhD and want to teach high school. What additional credentials do I need and what does it take to get them?
English
Note to humanities adjuncts laboring for minimum wage at State U: at classical high schools, you can teach what you love, students will listen and respond, parents will respect you, and job satisfaction will skyrocket.
Stephen G. Adubato@stephengadubato
Out of my 10 friends who got phds in the humanities in the last few years, only 2 got tenure track jobs. The rest are doomed to teach high school…or adjunct.

@biggsag @MarcGoldwein @crfb US SS formula delivers a much worse return to rich than to poor. Don’t want the rich to get such big checks? Don’t make them pay in so much.

These slides from @crfb are excellent. I'd add just one:
Social Security benefits are rising and will continue to increase. An rising share of benefits flows to well-off seniors, who get much higher benefits than in similar countries, and a low/falling share to the very poor.
CRFB.org@BudgetHawks
🚨 Social Security is the bedrock of the U.S. retirement system, providing benefits for 70 million Americans. And yet, very few know the facts about who the program supports and why it is facing insolvency in less than seven years... To answer those questions – and more – we launched our brand-new educational resource: Social Security, Just the Facts – an illustrated explainer that uses 12 easy-to-understand charts to break down how the Social Security trust funds operate, why they are projected to become insolvent, and what the consequences could be if no policy changes are made. Check out the Social Security, Just the Facts resource below ⤵️🧵

Walker Percy Gryce@percy_gryce
We need to normalize PhDs teaching high school. That solves at least two problems: absorbs some of the elite overproduction and put subject-matter experts (rather than ed school grads) in hs classrooms. (I know there are other problems.)

@NathanpmYoung @lymanstoneky @googlemaps Suppose I’m in the InterCity speeding north from Munich through the countryside in a train bound for Hamburg and I tell it I want to go Berlin. You want it to tell me if I should get off in Nuremberg, Frankfurt, or Hamburg and what trains to take from those cities?
English
Dear @googlemaps
Come on, you can realise when I’m on a train. They travel along train tracks. You know where the trains are. You know other people are doing nearly identical journeys.
Say “Are you on this train” and allow me to plan routes from there.

@WKCosmo I suppose one can solve the Schroedinger equation with a Newtonian gravity potential. (It would look like the H atom.) Is that what you mean? Are there also GR effects with calculable quantum corrections? What's an example?
English
This is one of the most persistently misunderstood things in physics, even by quite a few physicists. We already know how to quantize gravity at low energy. While it would be nice to have an experimental demonstration, it is well understood. The uncertainty is in the UV.
Deivon Drago@DeivonDrago
More people should be aware that quantum mechanics does, in fact, work with general relativity. Just because we don’t have a UV-complete version of quantum gravity does not mean that we don’t have ANY functioning theory of quantum gravity.
