This is a brilliant discussion of why anti-intellectualism works with the gen pop.

Argonne National Lab says to expect the worst about the superconductor, but they're still taking a shot at verifying it themselves.

LOL, twitter is now apparently completely blocked with no links working (if that's what that was).

Yes, it's dumb. And the same kind of pathetic move musk would pull

Well, the theoretical physics behind a fission weapon have been worked out for a good long time - not all the way to the actual Manhattan project (some of that was purely experimental), but not all that long after it. It’s why the US agreed to stop weapons testing - we’ve already got the theory down cold. Hit a mass of the right isotopes at the right density with enough neutrons at the right energy, and the bomb will go. At this point, building the next gen bomb is almost entirely a pure engineering problem - there are thousands of ways to achieve those conditions, so it’s just about selecting the design that optimizes for the other things that you might care about, such as the volume, weight, cost, reliability, safety, etc of the device. Pure nuclear engineering.

We've gotten the engineering down to such a point that "dial-a-yield" weapons have been available for decades.

There is a lot that needs to go right to get a nuclear detonation. Sure you have the reaction itself. But the means to get that to happen occur through quite a bit of mechanical means. So Mechanical Engineers would need to do their part. I'm sure structural engineers do a ton of work with the "delivery" system as well.

A nuke is one of the most complex devices mankind has ever built. It's not just one or three people that have their work in the kitchen with this.

Question about something I know zippo about but which has become an item of interest with “Oppenheimer.” I have a much older cousin who got his PhD in nuclear engineering at Cal and spent his career at Los Alamos “building bombs,” in his words. I assume he probably took a lot of physics, but that wasn’t his degree. So, the engineers design the build and the machines necessary to build, while the theoretical physicists provide the . . . what . . . cookbook? I don’t even know enough about it to frame the question.

It works that way in most industries. Physicists or chemists or someone comes up with an idea, then engineers come in to see if the idea is viable, and then they all work together to make whatever it is.

According to Maxis, large-scale fusion powerplants will be available in 2050. Too bad there isn't a cheat code to accelerate the process. ;-)

Given the speed of the projects, it fits right in. We still have 20 years before fusion, lol.

I think it's about five years too early to reconsider any existing projects on something just barely announced and only preliminarily replicated much less understood.
