Absolutely, the quickest way to lose faith in "The Science" is actually to do Science in a formal research institute....

Seeing how the sausage gets made makes you realize ALL the downsides and things you'd rather not have known. That doesn't mean you can think of a way to fix science. Let alone get the required funding to make an actual attempt.

Is there any particular reason why they keep building colliders with ever increasing diamaters, instead of going vertical? If we can create magnetic fields strong & precise enough to force particles into a very large loop, surely we can bend the loop upwards ever so slightly and gain additional distance by coiling the collider like a spring?

Seems like an insane amount of tunnels is always needed for these things, which is obviously expensive and labour intensive.

For scale: The LHC has more than 11km diameter and the deepest mine we have built is 4km. Adding vertical distance is much harder than making the diameter of the circular tunnel larger.

Automation of Hoare logic is quite good these days. Dafny, from MS Research (https://dafny.org), is probably the most friendly formal language of any kind. It's built around Hoare logic and its extension, separation logic. The barrier of entry is low. A seasoned imperative or functional programmer can get going with Dafny in just a few days. Dafny has been used to verify large systems, including many components of AWS.

I am hoping that LLMs make more advanced languages, such as Liquid Haskell or Agda, less tedious to use. Ideally, lots of code should be autocompleted once a human provides a type signature. The advantage of formal verification is that we can be sure the generated code is correct.

How do you encode the difference between a method that adds and a method that multiplies two numbers in the type signature?

Toronto Pearson had wind gusts of 60km/h today.

Edit: listing to the ATC audio I think they said gusts in the 30s (man do they ever speak fast and mumble! Enunciate damn it! Unique New York), which is markedly slower than what the Apple Weather app reported for Pearson.

Remember that ATC will give wind speeds in knots, not km/h.

I was referring to the "The US government is trying to bring back nuclear safety employees it fired on Thursday, but is struggling to let them know they should return to work, NBC News has reported. [...]An email obtained by NBC said the letters for some NNSA employees 'are being rescinded, but we do not have a good way to get in touch with those personnel'." part. It's about 300 people affected. And when you apply at these types of positions they ARE aware of private contact information.

Nowhere – I don’t follow the issue. The question was for those people who are somehow convinced that it’s complete chaos. In my experience, complete chaos is very rare, but fake reports of chaos in every field are a daily occurrence. If you believe every report of chaos that comes along, you’ll believe the world is ending every day. Which it obviously has not, yet. It follows that most reports of chaos are always false. Therefore, if you believe that some specific issue is really as chaotic as reported, you’ll have to have some pretty good sources to back that up.

How chaotic does https://www.bbc.com/news/articles/c4g3nrx1dq5o sound to you?

In my experience, normal people are quite confused by this. I've heard "Is that Juliette with a J?" and facepalmed.

In my experience people understand perfectly well but assume that you are ex-military.

Coincidentally, I've just finished Thomas' Religion and the Decline of Magic. It's very long and massively overexampled, but still a good and eye-opening read.

When it came out in 1971 it cost an extortionate £7; one national newspaper had an editorial saying people might be forced to pay for it in instalments.

petschge · a year ago
How is that extortionate? Using the inflation calculator of the Bank of England that is 86 pounds now or $110. Admittedly that more expensive than the current price of $24 for the paper back, but at worst that seems to be twice as expensive as a common price for a 850 page book?
