(odd interests) Mysterious cubes are likely Nazi experiments + What "Tenet" explored

Mysterious radioactive cubes found around US are probably Nazi experiments
https://www.iflscience.com/physics/myste...periments/

EXCERPTS: . . . in Captain America: The First Avenger there’s a Nazi-analogous organization trying to harness the power of a mysterious glowing cube in order to create a weapon of mass destruction [...] only for ... their cube to end up in a clandestine US research facility after the defeat of the Axis. Did you know it happened for real? Of course, it wasn’t an infinity stone that was powering the Nazis’ research – it was uranium.

[...] From the early 1940s, the Nazis and the US were locked in a race to figure out nuclear technology. The US had the Manhattan Project (and we all know how that turned out), and the Nazis had Werner Heisenberg ... At the heart of the research were these two-inch-long cubes of near-pure uranium: the hope was to exploit nuclear fission to transform them into plutonium, creating an atomic bomb.

Luckily, the program was disrupted before it could succeed, and the Allies confiscated many of the cubes after the war. But their fate after that is pretty murky: around 600 were shipped to the USA, but only about 12 are known today, with the rest being used in the US nuclear project, sold to private collectors and research institutions, or simply lost to the mists of time.

Even for the cubes we do know of, the provenance tends to be something of a mystery. The origins of the cube at PNNL are unknown, said lead researcher Jon Schwantes, with nobody sure how it even got to the laboratory at all... (MORE - details)


How the film "Tenet" explores entropy, information, and Maxwell's Demon
http://physicsbuzz.physicscentral.com/20...tropy.html

EXCERPT: . . . Such physical concepts are woven into the universe of the science fiction movie Tenet. Before its release in August 2020, director Christopher Nolan told EW that the film is not about time travel but rather deals with different ways that time can function. “Not to get into a physics lesson, but inversion is this idea of the material that has had its entropy inverted, so it’s running backward through time, relative to us.” Nolan hired physics Nobel laureate Kip Thorne to consult on the script, but caveats that the producers were “not going to make any case for this being scientifically accurate.”

So is the main character — referred to simply as “Protagonist” — a modern Maxwell’s demon? Let’s watch to find out. Spoilers ahead! (MORE - details)
