Archaeological evidence shatters the myth of men as hunters and women as gatherers

I fucking knew it. People have this idea that human roles are defined by biology. No, they are defined by competition. When we compete against the environment, being 20% weaker or smaller doesn't matter; you can throw a spear just as fine as the biggest person. When we compete against each other, being 1% stronger is a gigantic, monumental advantage.

This nonsense about gender roles is from lampooning nobility post-enlightenment. Us peasants have always just did what needed to be done.

The trick is that people believe the bill of rights is the only protection afforded by the constitution. The framers were against such a list of rights because it implies exclusivity and may ignore the precepts of the entire document: that we're all created equal and entitled to the pursuit of happiness. Surprise, surprise. As soon as landed white men were not the only ones covered by it, suddenly we split hairs about the amendments instead of the point of the entire document.

The bodies can't implode; the lungs can/will collapse but that is pretty much the least of the issues. Even if the bodies aren't pulverized by the collapsing sub, the water will hit like a hammer traveling at supersonic speeds. So probably a combination of rendering into mincemeat, dismemberment, and scattering of the human remains would result from such an implosion. A destruction on par with being hit by a bomb at ground zero.

But also how did he make that platinum coil? It has a melting point of 1772°C, so that can't possibly be fused together with the tools he had.

If you have the pure metals, then you can join pieces by getting them hot. In the case of platinum, it's highly ductile so you can cold work the pieces together. For the purposes of a catalyst, you don't even need to join them together; the key is to expose as much surface area as possible. It would actually better to shave it into smaller pieces. However, the Ostwald process reacts gaseous ammonia at a specific temperature so it makes sense that the platinum is suspended as a coil; to allow even air flow and to only catalyze the reaction with the gaseous form.

The documentation calls for 10% rhodium, but that is apparently to prevent the degradation of the catalyst.

The Most Misunderstood Concept in Physics

This is another one of those videos that spends a lot of time in lateral subjects without diving deeper in the main subject. I thought the idea that earth radiates energy made by biological processes fairly significant, and a far more interesting thought experiment to meditate on (Can we find aliens by looking at the thermal signature of exoplanets? Is there a methodology we can use to measure the efficiency of life?). Instead, it covers extremely basic principles of thermodynamics and heat pumps, which has been done to death in other videos.

What do y’all think about science anime (eg. Cells at Work, Dr Stone)?

Didn't like Cells at Work. Mostly because it's high-school levels of anatomy and physiology. It's fine for kids (although to be fair, even my graduate-level courses never talked about the primary cilium, and I learned about it by double-checking the show's depiction of neutrophils).

Dr. Stone I liked much more. It captured the feeling of science, even when it's generous with the capabilities of refining with primitive tools (e.g. getting access to pure ores is the only way to do anything they do in the show).

I'm surprised no one has mentioned Moyasimon: Tales of Agriculture. It is far more accurate to the science, is reasonably educational, and captures freshman-level college-life very well. I especially love how it will occasionally ditch tropes (e.g. the main character freaks out at the sexy dressed lady in the lab.... because she is swarming with ,microorganisms from not wearing PPE).

On the other hand, most other science in anime is complete and utter garbage. The rule of cool does not work with science; you have to be a crazy old guy with tenure to ever get the expertise to do dramatic things (like the guy who proved H. pylori caused ulcers by drinking a culture of it or the dude who invented PCR from an acid trip). Even then, science is littered with the bodies of people who did such things (the guy who discovered methylene blue, the Curies, the victim of the Devil's Core).

Most science in anime is some dude just hearing a cool word in english and using it in the vague way.
