The bhangmeters on Vela satellites were to detect atmospheric detonations: they exploit some odd optical characteristics of the fireball. They did have gamma, neutron, and X-ray detectors too but I’d guess those were also tuned to detect de

That's not a fair---or accurate---summary of Keynes. The claim is that the government should act as a stabilizer: spending to drive aggregate demand during downswings (especially ones caused by external shocks) and regulating during up

Here's a report[1] arguing that $1 spent on an NIH grant generates $2.56 of economic activity---and these grants largely aren't even meant to have short-term payouts. Block grants for (e.g.,) preventative care or education proba

Exactly! A lot (most?) of this spending has very obvious multiplier effects. Tax enforcement is a trivial and almost immediate example. Spending $X on compliance seems to recover about $5X in evaded taxes. On top of that, there are knock-on

Surgery can be slow, and brain surgery doubly so. The brain is slightly elastic, so you'd want to advance a needle glacially slowly (microns/second) into it so it ends up at the right position. The injection itself is also done sl

This is where the funders really ought to step up. A spokesperson from (say) NINDS really ought to be shouting to anyone who will listen about how excited they are to see their <many year>, <many dollar> investment in Huntingto

Even that quote is a bit of a disservice to modern science: it's a massive pyramid made of thousands and thousands of individual contributions, including many bits of deep background and outright "failures". Biology is tough

My impression is that boarding house usually includes some services (cleaning, maintenance, food) from the owner or an employee who lives on the premises.

“Puffery” isn’t that odd; it’s all about context. We want people to tell the truth, obviously, but we also don’t want to litigate obvious hyperbole. It should be possible to describe something as “the best thing since sliced bread” without

It is and it isn't. "Rich people can afford a luxury" is obvious enough, but how rich did you need to be to hire that specific artist? Was Sargent knocking out two portrait a day for every local dentist or was this a one-off

Definitely -- get something meant for a lab. I worked in one that had a 150F water bath running day and night.

Depending where you are, low (and high) protein flour can be hard to find at the supermarket.

by mattkrause 1y ago
For cakes, you often want less gluten (~7-10% protein) and that flour is not super common. All-purpose flour “works” but the product will be a little bit tougher because it a bit more protein instead.

Art museums are even worse. "Portrait of Duke von Duke (London, 1841). Oils." Who is this guy in the painting?! How did he merit a painting? What's unique about the style/composition/whatever? Conversely, I went to

I think there's also a misunderstanding of how these tunnels "work" in practice. The ones in Montreal (and Kobe, Toronto, etc) don't seem to replace surface streets or transit; they complement it. The Réso in Montreal ov

Eh... Montreal is a lot less temperate (in both directions!) than Barcelona and Helsinki. Having a way to get out of ±35º weather really does make the city more livable.

The word seems to slightly predate WWII. The OED reports that the disrupted-electrical supply sense of blackout was first used in 1934; the air-defence one (no light) in 1935. However, the OG use seems to be in the theatre, where the lights

by mattkrause 1y ago
Is that the origin? I thought it was an analogy to the electrical problem: flickering lights due to high demand.

Looks like a semi-colon gone awry.

Eh... Suppose A solves a problem and writes the solution down. B reads the answer and repeats it. Is B reasoning, when asked the same question? What about one that sounds similar?

It’s not how the records are kept per se. It’s that the paper-using doctor can spend more time on you, the patient, instead of fighting with a balky UI and inane business rules.

For me, the difference between ration and hoard is the uhh…rationality of the plan. Rationing suggests a deliberate, calculated plan: we’ll eat this much at these particular times so our food lasts that long. Hoard seems more ad hoc a

That should be only sort of true. Some of the very high-profile journals are run by non-profits, including: Science (American Association for the Advancement of Science), PNAS , (National Academy of Sciences), eLife (HHMI/Max Pl

I always find that a little annoying: it takes way too many clicks (esp. for a birth year) and then you've got to find the day of the week. I'd hate it less if typing updated the widget.

I thought this was sort of deliberate for Apple Health. People use it to track sensitive information, like reproductive and mental health data, that should only be exported very intentionally.

My only real beef with the article is that "Uneasy about easing functions" would have been a much better title.
