A man jumps out of an airplane with a parachute on his back. As he’s falling, he realizes hiss chute is broken. He doesn’t know anything about parachutes, but as the earth rapidly approaches, he realizes his options are limited; he takes off the parachute and tries to fix it himself on the way down. The wind is ripping past his face, he’s dropping like a rock, and at 5000 feet, another man goes shooting up past him. In desperation, the man with the chute looks up and yells, “Hey do you know anything about parachutes?!”
The guy flying up looks down and yells, “No, do you know anything about gas stoves?!”
Interesting Fact: The first ascending-gliding parachute was developed by Pierre-Marcel Lemoigne in 1962. The same year, Lemoigne established an Aeronautical Training Center to introduce his new ascending-gliding parachute as a training tool for parachutists. The technique allows parachutists to train more efficiently by towing the parachutist to a suitable altitude, then releasing them to practice landings. This training method proved cheaper than—and just as effective as—an airplane. In 1963 Jacques-André Istel from Pioneer Parachute Company bought a license from Lemoigne to manufacture and sell the 24-gore ascending-gliding parachute which was trade-named “parasail.” ( https://en.wikipedia.org/wiki/Parasailing#History )

Interesting Fact: Ospreys are excellent anglers. Over several studies, Ospreys caught fish on at least 1 in every 4 dives, with success rates sometimes as high as 70 percent. The average time they spent hunting before making a catch was about 12 minutes—something to think about next time you throw your line in the water.

Interesting Fact: Nonbreeding adults eat about a quarter-pound of food daily, or a tenth of their body mass—that’s about 5 small mammals. Nestlings start feeding themselves (swallowing lemmings whole) at about 16 days old. It’s estimated that a brood of 2 nestlings requires 26 pounds of food during the 40 days between hatching to fledging. ( https://www.allaboutbirds.org/guide/Rough-legged_Hawk/lifehistory )
There were three workers; one crane operator, one pole climber, one guide.
The guide tied the crane to the end of a pole. The crane operator would then pick the pole up on end. The climber climbed to the top and dropped a tape measure which the guide promptly read and noted the measurement. The crane operator then lowered the pole to the ground and repsitioned to pick up another pole.
This went on several times when the foreman came over and asked why they couldn’t measure the poles while they were laying on the ground?
The worker replied, “we need to know how tall the poles are, not how long”.
Interesting Fact: It is assumed that Roman engineers lifted these extraordinary weights by two measures. First, as suggested by Heron, a lifting tower was set up, whose four masts were arranged in the shape of a quadrangle with parallel sides, not unlike a siege tower, but with the column in the middle of the structure (Mechanica 3.5). Second, a multitude of capstans were placed on the ground around the tower, for, although having a lower leverage ratio than treadwheels, capstans could be set up in higher numbers and run by more men (and, moreover, by draught animals). This use of multiple capstans is also described by Ammianus Marcellinus (17.4.15) in connection with the lifting of the Lateranense obelisk in the Circus Maximus (ca. 357 AD). The maximum lifting capability of a single capstan can be established by the number of lewis iron holes bored into the monolith. In case of the Baalbek architrave blocks, which weigh between 55 and 60 tons, eight extant holes suggest an allowance of 7.5 ton per lewis iron, that is per capstan. Lifting such heavy weights in a concerted action required a great amount of coordination between the work groups applying the force to the capstans.
