Once there was a golfer whose drive landed on an anthill. Rather than move the ball, he decided to hit it where it lay. He gave a mighty swing. Clouds of dirt and sand and ants exploded from the spot. Everything but the golfball. It sat in the same spot.
So he lined up and tried another shot. Clouds of dirt and sand and ants went flying again. The golf ball didn't even wiggle.
Two ants survived. One dazed ant said to the other, "Whoa! What are we going to do?"
Said the other ant: "I don't know about you, but I'm going to get on the ball."

Liquid oxygen

In 1877, Louis-Paul Cailletet (1832-1913) became the first to liquefy oxygen. Shortly after, he also was first to liquefy nitrogen, hydrogen, nitrogen dioxide, carbon monoxide, and acetylene. Cailletet realized that the failure of others to liquefy the permanent gases, even under enormous pressures, was explained by Thomas Andrews's concept of critical temperature. He succeeded in producing liquid oxygen by allowing the cold, compressed gas to expand, depending on the effect discovered by Joule and Thomson, that cooled the gas to below its critical temperature. In later experiments he liquefied nitrogen and air. Raoul Pictet, working independently, used a similar technique. He also invented the altimeter and the high-pressure manometer.Image: Cailletet's Liquefier.
