Technically that's mostly how it's supposed to work in the US. Partisan politics and a bunch of weird rules mean it doesn't work as well as it's supposed to be.

I guess I'm wondering why nobody seemed to notice this before?

The US has been graded as a flawed democracy pretty well since people started measuring such things. You're maybe noticing now because somebody got elected who has no qualms about publicly taking full advantage.

Ponzi schemes have the characteristic that the gains of investors on the way out are paid by investors on the way in, without any actual gain via production. Someone to "collect money at the top" is not required.

Bitcoin was arguably not a Ponzi scheme when it was supposed to be a currency, but when it became an "investment" it became one.

Comment Backdoor? (Score 2) 39

That doesn't really sound like a backdoor.

The original article says the standard cut it down to meet export control requirements. The algorithm in question is one of four choices, and the standard makes pretty clear that it's the one for shady foreigners:

The Cipher Key has an input length of 80 bits;
the Initialization Vector has a length of 29 bits. The effective Cipher Key length of TEA4 is reduced within the
algorithm to 56 bits to permit worldwide exportability without restriction, at time of definition.

The more important anomaly is the JWST observation of galaxies that formed when the Universe was "too young for those galaxies to form".

If you push back the age of the Universe to allow those galaxies to form then you push on the coefficients of expansion and those need to agree with theory which they do not under current theory.

Some theories are compatible but lack a Big Bang which is taken as an article of faith by most and need more observations to consider.

Scientists not agreeing *is* science. If the schools fail to teach that in 13 years that's a massive indictment of the schools.

It's as if it was a bad idea to base hiring and promotion on the number of papers published, and then also pay publishers by the number of papers published.

Someone posted this graph:

WTF happened in 2008/2009? It's when the idea of paying publishers by the paper instead of them having to convince a bunch of librarians they weren't frauds started to take off (PLOS One launched in 2007).

That's the problem.

Regular submarines are buoyant because the volume of low pressure air enclosed by their hull makes them overall weigh less than the water they displace. They have to carry ballast, which might be weights or water pumped into tanks, in order to dive. This is nice beacause when you want to come back up you can drop the weights.

To dive deeper you need a thicker hull to withstand the pressure. At some point your steel hull plus the enclosed air is heavier than the water it displaces. Then you sink instead of floating, even with no ballast. So you need to carry some means to generate additional buoyancy. We normally use some kind of foam for that, but the pressure would crush normal foams so you need to use super strong (and expensive) syntactic foam materials.

If you can make the pressure hull out of something that has a better strength to weight ratio than steel you can dive deeper without supplemental buoyancy, or use less to go even deeper. Titanium (and carbon fibre) also have the advantage that they don't rust in sea water.

Here's a paper discussing titanium hulls: https://cdn.ymaws.com/titanium...

While stuff like that does happen, the big reason we have regulations is indeed because the value the free market places on lives is not what we'd like it to be. There are lots of cases where companies were perfectly able to pay out settlements. The Ford Pinto case is the classic example of a company specifically choosing the expense of settling lawsuits over the expense of fixing a dangerous product.

When I was a teenager the local autobody guy who'd just informed me my first car wasn't worth repairing noted "they're always worth more to us than they are to anybody else." Goes even more so for lives.
