Right -- for example, the "Joking" and other stories are written by Ralph Leighton[1]. Interestingly, Ralph is son of Robert Leighton[2], the caltech physicist who was a contemporary (and peer) of Feynman's and part of the

In Cat's Cradle, "Ice 9" is an idea that sweeps across the world destroying it. It's an allegory.

Which books did Feynman write? Lot's of people have written books and said they're "stories told by Feynman" but that's not really the same thing as "Feynman dictated this story and reviewed it with the editors

So some rough numbers from trivial googling[1]: At "low pressures" (5-30x normal sea level atmospheric pressures) H2 needs roughly 2.5meters cubed to store 1kg of H2. Apparently it's "normally" stored at 350 to 700

A cryogenic pressure vessel that's not affected by hydrogen embrittlement is hardly portable, cheap, or energy dense. Maybe if you're using a vehicle that's otherwise going to use bunker fuel, sure, you've got space for

This is actually the answer. Diesel generators running at a fixed duty cycle and optimized for efficiency can be way more efficient than a mobile diesel engine operating at a wide range of workloads. "Diesel" can run on a variety

H2 is a terrible substance; it destroys whatever you use to store it, it leaks like crazy, you need to compress and chill it to get any kind of density, you need to store it at crazy low temperatures. For instance, the toyota Mirai's t

A statement like "EVs pollute more than ICE engines" needs substantiation. Large power generation systems (even messy ones like coal) are tremendously more efficient per unit CO2 produced than a car engine[1]. You could make a ca

Converting the excess energy into hydrogen is a really inefficient way to store the energy. Hydrogen ruins whatever it's stored in, it requires a huge amount of energy to store the hydrogen in a space efficient manner, etc. Heat some s

Of course the mitigations get disabled. What's the threat model where your HFT application's running hostile / untrusted code? I'd like this stuff enabled on my desktop because I'm not sure what hideous javascript i

Programs are communication between 2 loosely coupled audiences -- the humans who have to maintain / modify the code and the computer that gets to run the code. Human language, used to convey ideas to other humans, is imprecise. It&#x2

These ad-hoc efforts are wonderful and extremely effective and are the utopia we all strive for. Ultimately, I think, the distinction between "products" and ad-hoc effort is that one is tolerant of abuse and bad actors (the "

Another way, theoretically, is to privatize/keep profits and put losses on the shoulders of taxpayers. I don't think such unethical activities are ever done in the real world, though.

I thought halon was "harmless" to people, but mixing halon with fire produces nasty poisons. The vast majority of fire suppression events I've heard of (in a DC or similar environment) are unintentional, meaning the halon

People need carbohydrates. Sugar is one of the possible ways of getting carbohydrates, certainly one of the most delicious. You won't get sick if you get your carbohydrates from some non sucrose / fructose source.

The sayings are "the dose makes the poison." or "The solution is dilution." I've found over time that neither aphorism is true. The poison is poison, regardless. Caffeine, Sugar, Plastic, Alcohol, Social media ---

People are comparing intel vs AMD here, but in this context -- AMD doesn't actually make the chips do they? They've designed the chips and other companies such as TSMC make the chips. A chip plant / "fab" is the

I was wondering; it seemed like if the to airports were 36000 angstroms apart (3600 nanometers), it'd be reasonable to give them the same airport code since they'd be pretty much on top of each other. I've also seen "DAN
