China has this in a big way. The big energy sources are mostly in northwest China, and the big loads are in the southeast. That's why China leads in million-volt DC power transmission.

Yes. Apollo had a lot of WWII military people. The dud leaders in the US military were mostly identified early in the war and kicked out. Gen. George C. Marshall established a "plucking board" in 1941 to remove bad officers.[1] &q

So they don't have to handle the really hard case. In x86 land, it's hard to find the instruction boundaries statically, because, for historical reasons going back to the 8-bit era, x86 nstructions don't have alignment restri

Einstein spent his later career trying to reconcile general relativity and quantum mechanics. He failed. So has everyone after him. It's not about Einstein being old. It's that it's a really hard problem.

It's the 3% silver that does it. That gets the melting point down. Unfortunately, the price of silver has tripled since 2023. Hobbyists won't use enough solder to notice, but it's an issue in production.
