Ah, don't worry. He'd forgotten ten minutes later and I later took him rock climbing, which he actually loves and I support him doing despite me being terrified of heights.

Are the children allowed to sit and study all day on the topic they're currently interested in? No. https://cantrip.org/gatto.html They're required to submit to authority at all times. How could it be otherwise in

USA here: our schools brainwash children to remove that skepticism. It makes them easier to control and order is very important to the kind of person who becomes a teacher. Seattle area, they're brainwashing my children to celebrate th

You're comparing an average, but the demographics are different. If you compare, say, native-born-white to native-born-white, they fit those inputs much closer. Total fertility is down because a smaller fraction of the population are i

Renewable PV is the cheapest way generate electricity during daytime at appropriate latitudes. Notice several caveats: electricity, not heat; daytime, not nighttime; only for some places on the globe. Most energy use doesn't use electr

So, the NPE isn't a real Nobel Prize :) but if the only allowable decisions are to concentrate wealth at the top, then we're just delaying and amplifying the collapse.

Uh, no, we're having a generational crisis because wages are flat and rent cost has been growing for decades. That's quite reprehensible. Unfortunately, in our push for home ownership, we now have a majority of people being homeow

2008 was caused, in part, by the governments deciding many "banks" were "too big to fail". The fix was for the government to pick some winners, coercively lend them money and force them to buy the failing banks. Now we h

1. No, absolutely not. Why would you settle for COP=1 when you can have COP>1? 2. The electrical to heat conversion efficiency is indeed 100% regardless of the temperature of the resistor. And if you're putting out 1000W, then all i

They don't work well with heat pumps. Heat pumps lose efficiency as the differential increases, so if you try to store heat in a tank, you quickly drop capacity and efficiency. Versus resistance, which is exactly as efficient at 0°C an

Thank you for sharing. I now also have a better idea of what wording to look for in the future.

I don't think it was a stunt. It was an experiment. I think passive cooling (running hot) reduced some of the advantages of undersea compute.

They use evaporative cooling towers because you need far fewer of them. The evaporating water can be separate from the main cooling loop. https://en.wikipedia.org/wiki/Cooling_tower#Heat_transfer_me...

Why can't we add friction to save lives? Automobiles are the single leading cause of death for children in the USA! We're not talking about something uncommon. Remove the free parking if that's making the road unsafe. Or driv

IIRC they required all games to work without 3D (because some people couldn't see it? or it gave them motion sickness?), so it could never be a core mechanic and thus doomed to be a "neat trick".
