It was likely the measurement of the distance between the airport and the building that was the problem. edit: thinking about it, it still doesn't make sense. The difference in distance would be about 2 cm over 10 km.

This makes it sound like the elastic deformation at the bottom balances out the forces that are pushing the mountain up. But we know that this is currently not the case, because we observe the Himalayas getting several centimeters taller ea

The oxidation of nitrogen gas is endothermic though. It can't produce heat to sustain a runaway reaction.

It also helps that the Himalayas have slowly grown from nothing over the past 50 million years. The ancestors of the bar-headed goose had the opportunity to gradually adapt as the mountains rose. (Not all birds can do this, even with their

With 80% efficiency, you have to burn 1/0.8=1.25 units of fuel to get one fuel unit worth of useful heat. With 97% efficiency it's 1/.97≈1.03 units. So if fuel prices and the amount of useful heat usage stayed the same, then

I believe none of the Fidelity funds have even a 0.1% weight for SpaceX. (I haven't checked recently and I can't read the blog because of HTTP 451, but I don't think this has changed.) I criticized buying Google in my other c

SpaceX is valued at $36B, times 7.5% would be $2.7B for google's stake. Divide by google's market cap of $973B and you get 0.29%. Investing $100 into Google to put 29 cents on SpaceX doesn't seem efficient. SpaceX could doubl

The biological reason for having males and females is ultimately game-theoretical: males spend less energy on reproduction. Females spend more energy (pregnancy), but compensate by demanding higher evolutionary fitness from the males. The m

Sounds like something that could be solved with food irradiation [1] after the cheese has ripened, to kill the mites. It's similar to pasteurization, but without any of the heat which would melt the cheese. And it's already FDA ap

I guess because plainly visible "tall masses" are not the only things contributing to the geoid? E.g. earth crust thickness might dominate. In the context of this discussion, we're not so much interested in the absolute shape

This reminds me of those code reviews where you have a colleague that prefers to spend hours trying to refute reasonable minor comments, instead of 5 minutes to address them.

If "the Fed is printing money at an incredible pace", as stated in the post, then it might be unwise to sell one's assets for that same money.
