In 1152, young William Marshal was held hostage and almost executed by catapult. When he saw the catapult’s sling, he took a step back, and said, “Gracious me! What a swing! It would be a good idea for me to have a swing on it.” He went right up to the sling www.medievalists.net/2014/01/how-...
Log scales are for quitters who can't find enough paper to make their point properly. - xkcd.com/1162/
Not just the log scale. What the alt text is about is much more powerful - it’s more like this, of which a log scale is only the first step: en.wikipedia.org/wiki/Knuth%2...
@xkcd.com Hear me out. What about late period Pleistocene birds of prey lifting early humanoids? Haast's Eagle 🦅of NZ?? xkcd.com/3039/
On July 2, 1982, Larry Walters (April 19, 1949 – October 6, 1993) made a 45-minute flight in a homemade aerostat made of an ordinary lawn chair and 42 helium-filled weather balloons.[2] The aircraft rose to an altitude of about 16,000 feet (4,900 m) en.m.wikipedia.org/wiki/Lawncha...
Should be a spike to 1400km at the end for Polaris Dawn en.wikipedia.org/wiki/Polaris...
> I wonder what surviving human held the record before balloons For an upper bound: Juliane fell 3000 m from a plane & walked away, Mount Thor has a 1200 m cliff. en.wikipedia.org/wiki/Juliane... en.wikipedia.org/wiki/Mount_T...
There were a few high-altitude balloons in the 1930s that should be higher than any peak here :P Someone needs to read more @nealstephenson.bsky.social
I just listened to it, so now you have to: www.youtube.com/watch?v=Pl_Y...
en.wikipedia.org/wiki/Auguste... Auguste Piccard, also the inventor (though not the pilot) of the first submersible to reach the bottom of the mariana trench, and the inspiration for Professor Calculus in the Tintin books. (Probably also the inspiration for Jean-Luc Picard's name).
I find the troughs as interesting as the peaks. Is it air mail service that had planes cruising around 24/365 in the early 20th century, at low altitudes? Can't think of a reason the troughs would get higher other than planes in the air (somewhere in the world) round the clock. Space stations later.
