We are somehow approaching a political system where: 1) Every person who can tell true from false is united on one side. 2) That side still loses about one out of two elections.

I use a classic water-boiling humidifier (a Vicks). It's very cheap, needs no special water, and puts no particulates into the air. It acts as a small steamy heater, which would be bad if I lived in a hot dry place, but in my climate I only need it in winter anyway.

As a kid I wondered why Republican politicians didn't sound like the conservative Fox-watching New Yorkers I knew. Well, now they sound exactly like them.

Closer to home, Saturn's moon Titan has lakes of natural gas on the surface like water. Some people I've mentioned this to have been amazed that we don't just go get it.

When a conservative has truly messed something up beyond recovery, he either says that thinking about it is unpatriotic, or that thinking about it is womanly.

It could also be cowardice: waiting until he was fairly sure Trump was too weak to retaliate.

This result is crazy. You finetune a teacher model to love owls. Then you have the teacher model generate a string of numbers, and finetune the student model on those numbers. The student model will then also love owls. alignment.anthropic.com/2025/sublimi...

It makes sense if you assume there's no link between what politicians will do and what the marginal voter expects.

It would be nice if there really were a third rail of American politics, as opposed to some things that cost maybe 2-5% each in a polarized environment.

It's an absolutely cursed incentive structure for sure, but maybe we can get the doctors on board. For instance, a law that subsidizes all doctors' pay and also stops the AMA from limiting the doctor supply. There's no law of nature that says doctors' pay has to be set by supply and demand only.
100
James Stevenson @allaboutchemist.bsky.social · 08/10/2025
I think you're right. If we paid doctors 50% more and got rid of the AMA, before long we would have a cheaper healthcare system overall.

James Stevenson @allaboutchemist.bsky.social · 08/10/2025
The AMA causes a lot of problems, but isn't all doctor compensation in the US around $0.5 trillion? Whereas the healthcare system as a whole is ten times that. If doctors were paid half what they are now, the savings would be enough to offset healthcare inflation for about one year.

James Stevenson @allaboutchemist.bsky.social · 08/10/2025
You're right. Total compensation for all doctors in the US is around 0.5 trillion dollars, compared to about 6 trillion for the healthcare system in total. If all doctors were paid half what they are now, insurance premiums shrink less than 4%.

It reminds me of physicists saying that chemistry is solved since we know the Dirac equation, or a kid thinking they can open any combination lock once they know how to spin the dials.

Yes, exactly. And nobody but specialists seems to know about it yet. If we posted the price of solar cells by the side of the road like we do the price of gas, maybe politicians would notice that they have some rethinking to do.

I found a strange match between periodic cubic splines and a certain integer series: instead of solving a linear system of size N, you would just use N terms. I suspect the number theory is known but the application is novel. Never published because the benefit is small for ordinary values of N.

I agree, but it's important to note that this is easy to mess up. How often has the NY Times interviewed a "swing voter" who turned out to be a local Republican bigwig? It's easy for one's model of the marginal voter to be confused by prejudice and accessibility bias.

It’s much harder to build housing in Blue states than it is in Red states. So yes people are moving away from Blue states. One more reason that addressing the housing shortage in NY and elsewhere must be an urgent priority.

I felt rather betrayed when I learned that mineral sunscreens often work by means of "SPF booster" compounds like butyloctyl salicylate which are basically repackaged chemical sunscreens.
