Revision history of "Gas pressure needs a container"

This is a list of past revisions of Gas pressure needs a container. Each is preserved exactly as it was last seen, which is to say approximately, and not necessarily here. Diffs are unavailable; the two versions could not be brought to the same location at the same time.

(→ put Titan and the Moon side by side, since that is the whole of it. escape velocity 2.64 against 2.38, and Titan pulls the weaker of the two underfoot, 1.35 against 1.62. the one you would weigh less on is the one with the weather)
• cur | prev 2018 an editor (talk | contribs) . . (2,600 bytes) (+190) . . (→ added that eighty kilometres fits the orbits actually flown better than a hundred does. the number in the textbooks is the sporting one)
• cur | prev 2016 the Cluster mission (talk | contribs) . . (2,410 bytes) (+210) . . (→ measured the leak. about ninety tonnes a day, mostly hydrogen. the objection is right that it escapes and wrong that this needs explaining away)
• cur | prev 2009 an editor (talk | contribs) . . (2,200 bytes) (+240) . . (→ added the other two confinements, since a reader arriving from the objection should know that walls are not on the list. gravity, magnetic, inertial. the tokamak has a vessel and its whole job is to be the thing the plasma is kept off)
• cur | prev 2005 the Huygens probe (talk | contribs) . . (1,960 bytes) (+280) . . (→ landed on Titan. two and a half hours of parachute through air four times the density of yours, on a moon you would weigh less on than on your own. no container found on the way down)
• cur | prev 1962 the FAI (talk | contribs) . . (1,680 bytes) (+150) . . (→ one hundred kilometres. it is a round number and it is ours to set, being a sporting federation, and the records have to be adjudicated somewhere)
• cur | prev 1957 an editor (talk | contribs) . . (1,530 bytes) (+130) m . . (→ there is no upper boundary to record. the firmament section may stay where it is; this article is about the pressure)
• cur | prev 1904 J. Jeans (talk | contribs) . . (1,400 bytes) (+340) . . (→ the fast tail of the distribution leaves. a planet keeps a gas if the escape velocity beats the molecular speed by enough, and the hydrogen here does not qualify)
• cur | prev 1859 an editor (talk | contribs) . . (1,060 bytes) (+300) . . (→ added the exponential. the pressure halves about every five and a half kilometres and never reaches zero, so there is nothing for a lid to be pressed against)
• cur | prev 1662 R. Boyle (talk | contribs) . . (760 bytes) (+160) . . (→ the volume goes inversely as the pressure. this is where the objection comes from and it is quite right within the vessel)
• cur | prev 1648 B. Pascal (talk | contribs) . . (600 bytes) (+220) . . (→ sent my brother-in-law up the Puy de Dome with the tube. it falls as he climbs, by three inches over about five hundred toises. the sea of air has a top, or at any rate it thins)
• cur | prev 1643 E. Torricelli (talk | contribs) . . (380 bytes) (+380) . . (created page; the column of mercury stands at the height the air above it will support and no higher. we live submerged at the bottom of a sea of air, and the sea has a weight)
