Reply to ELI5 what's a surplus? by CalmlyPsychedelic
It's "more than we need". For example, you need one bag of rice to survive the winter, and in Fall you collected 1.5 bags of rice. So you ended up with a 0.5 bag of rice sulprus. Same concept applies on a big scale in economy when goverment expected to collect this much money from taxes and trade, but ended up with more money than planned.

Speed of individual air molecules about 500 m/s, so just a bit faster that speed of sound in air.

Reply to Anyone else hate 3D movies? by sadlibra
Not me. I live them! I love the "I'm there" feel of it, the immersion. Though I do agree, some 3d movies just add pop put stuff for gimmics, and some turn the whole movie into some sort of "experience", at which point its hard to call it a movie. Gravity for example. Fantastic theatrical 3d experience, horrrrrrrible movie. But for majority of movies, I feel like the added depth is nice.

Reply to How do fusion scientists expect to produce enough Tritium to sustain D-T fusion (see text)? by DanTheTerrible
Tritium is also a byproduct of Nuclear Power industry where heavy water used for moderation, like the Canadian designed CANDU reactors. In Darlington for example, there is an entire Tritium Removal Facility used for purification of tritated heavy water and exports tritium. If demand for tritium increases, so can tritium production

It uses electromagnets, that run insane ammount of electric current in order to generate required magnetic field. The only way to achieve it, that we currently know of, is by using superconductors - materials that allow electricity flow with very very little losses. (Electrical resistance of conductors increases with temperature) Superconductivity is achieved by cooling the material to as close to absolute zero as possible.

Reply to Eli5: On a production line, how do they make a car, plane or anything else be identical from one another without differences? by SideburnG
Quality control. Each component is made to specifications, and if it doesn't meet specification, it gets tossed/recycled.
For example, car needs a 50.00mm +/- 0.01mm rod in length, 10.00 +/- 0.01 mm in diameter. Worker makes 10 rods. Quality control checks them, finds that one rod is 50.05 mm long when max permissible is 50.01. Tosses it.
