Space dynamics are not that much deterministic. Gravity itself is kinda noisy (Earth isn't an ideal sphere with uniform density), there's the Moon, orbital decay (caused by drag from particles in low orbit, which is variable), sol

Since that happened (a year ago) the Supercharger network grew from 6473 to 7377 stations, and from 59596 to 70228 connectors (numbers from Q2 2025 earnings release), so it's not like they stopped expanding the network after that layof

I think a big part of the valuation is self driving. If (and that's a big if) they would get it right, they could have cheaper taxi services than e.g. Uber ($200B market cap), without paying for drivers. And if self driving would work

Not the lowest power, but surely it uses less power than a microwave. 360W TDP, 850W required system power, while my microwave is 1000W.

So, given that human body area viewed from the front is around 0.5 m^2, then a 70 kg human in space 1000 miles from the explosion would get 6.4 kJ * 0.5 / 70 kg = 45 gray. That would mean that even being a couple thousand miles away co

I wondered how much energy could pass through some area 1000 miles away from the explosion, so I made some rough calculations. Assumption: all energy of the nuclear explosion is radiation uniform in every direction. The energy E would be sp

The way I understand it, they say that animals react better to danger coming from the left side, because the left visual field (of both eyes) is processed by the right hemisphere, which is dominant for threat processing and spatial attent

The hardest thing in developing nuclear weapons is getting enough enriched uranium, and Iran was doing that.
