Feeling edgy, a man took a hot...

Feeling edgy, a man took a hot bath.
Just as he became comfortable, the doorbell rang. The man got out of the tub, put on his slippers and robe and went to the door.
A salesman at the door wanted to know if he needed any brushes. Slamming the door, the man returned to the bath.
The doorbell rang again. On went the slippers and robe, and the man started for the door again. He took one step, slipped on a wet spot, fell backward, and hit his back against the hard porcelain bathtub.
Cursing under his breath, the man struggled into his street clothes and with every move a stab of pain, drove to the doctor.
After examining him, the doctor said, "You know, you've been lucky. Nothing is broken. But you need to relax... Why don't you go home and take a long hot bath?"

Liquifaction of oxygen

In 1879, the liquefaction of oxygen was announced by Raoul Pierre Pictet (1846-1929), a Swiss chemist and physicist, by sending a telegram to the French Academy: Oxygen liquefied today under 320-atm and 140 degrees of cold by combined use of sulfurous and carbonic acid. French physicist Louis Cailletet made a similar announcement two days later. Pictet's early interest was in ice-making machines. Later, he studied extremely low temperatures and the liquefaction of gases. Both Pictet and Cailletet used both cooling and compression to liquefy oxygen but they achieved this using different techniques. Pictet's method had an advantage in that produced the liquid gas in greater quantity and was easier to apply to other gases.[Image: part of a Pictet machine to cool down glycerine, which was pumped through a piping system in the first artificial skating track:]
