1/28 A propeller in a tube straight through the bow, pushing the front of the ship sideways. At a standstill the bow thruster is simple. Once the ship moves, the water around the hull fights it. How it works, where it came from, and why it fades with speed. #shiphandling

New post! In which I discuss a truly amazing piece of science sleuthing that recently appeared on @pubpeer.com neuroskepticbsky.substack.com/p/the-sherlo...

I see yet again that the French are revolting

MiG-23 aerial victories Short🧵 I'm not someone who pays much attention to counting aerial kills. Firstly because I'm more interested in engineering & flight performance, secondly because counting kills means little without understanding the circumstances under which the kills occurred.

This is an incredibly researched & well written article about the growing need for relocation of several villages in rural Alaska & the many conflicts over how to do that & how to pay for it. I can not recommend it enough; just outstanding journalism.

Sympathise, but this is a singularly unfortunate choice of analogy!

The Cylons were created by Man. They Rebelled. They Evolved. They look and feel Human. Some are programmed to think they are Human. There are many copies. And they have a Plan.

the year is 2030 and i no longer consume anything that isn't personalized to me. every game, every book, every movie extends to the limits of my own imagination and no further. i haven't been surprised in five years. i cry softly, in bewilderment, if i see a word i don't know

This seems to be a total collapse of ethics review. There is a reason that experienced scientific and medical researchers review studies that involve human subjects. Another safety valve is usually the funding agency, which normally wouldn’t let this through. But, you know…RFK Jr.

The 1937 Amiot 370 was a record plane derived from the Amiot 340 bomber, and set eleven international speed records. Flying at 437 km/h over 2000 kms with different loads (500, 1000 and 2000 kg). It also held the speed record over 5000 kms and 10000 kms.

I am a barrister who once spent time seconded to the CPS serious crimes unit making charging decisions. Today, you can pretend to be one too and work through the decision-making framework in a very serious case. The police have multiple suspects in custody and the phone just rang. 👨 👨 👨 👨 👨 📱 👮‍♀️ 🚨

This is a poor take that suggests Owen Jones doesn't know much about Russia in the 1990s, including Russia-US or wider Russia-West relations in the 1990s. By giving only one part of the story, he is repeating the Russian political elite's self-serving line that it was all the West's fault. Long 🧵

Dear British Airways: This very public thread has shown your airline to be a primary example of some of the worst customer service in modern airline history. Diversions for medical emergencies happen, but everything after that is on you. You guys need to be shelling out refunds BIG time.

The Facial Expressions of Tethys by artist Julius von Bismarck. A suspended high-sea buoy that moves in real time. Sensors on a twin buoy out in the Atlantic Ocean send live satellite data to motors inside the museum. This makes the indoor buoy copy the exact, real-time movements of the ocean waves.

I love a straightforward accident report. This pilot failed to avoid a cow. Yep. That will totally ruin your day.

1/x A man is remembered for two contrasting legacies: heroically saving the US Declaration of Independence from flames, while his mismanagement of US lighthouses left the American coast shrouded in darkness and filled with shipwrecks. This is Stephen Pleasonton. A small 🧵 #maritimehistory

Having observed the performance of the Fieseler "Fi-156", France decided in the late 1930s to acquire an aircraft with similar characteristics. The "SFAN-11" was therefore a prototype observation aircraft from 1940, designed for short take-off and landing capabilities.

1/x In 1971, Boeing faced an existential crisis. A billboard emerged, declaring, "Will the last person leaving Seattle turn out the lights?" after the company laid off 63,000 employees. Boeing needed something other than airplanes? The Jetfoil was born. A small🧵 #maritimehistory

New study finds the social cost of driving a car 1 km—including pollution, crashes, infrastructure, and noise—is more than *triple* the private cost paid by the car owner. doi.org/10.1016/j.tr...

As both an academic and a writer, I am repelled by the "this looks like a long document. Would you like me to summarize it for you?" that seems to appear at the top of every pdf viewer now. NO. The *entire point* of good writing (either books or journal papers) is that every sentence has a purpose.

More and more studies show that vaccination against various infectious diseases also leads to fewer cardiovascular deaths and lower rates of dementia. A rational public health system would be getting as many people vaccinated as possible. But. . .

I can easily imagine future historians trying to make sense of our age and coming up with elaborate and wild theories, and endlessly fighting over them in mountains of books — because the implausible truth is that it makes no sense at all.

Good luck, I guess…
