FluorineIn 1886, Henri Moissan's discovery of fluorine gas was announced at the Paris Academy of Science, two days after his first successful experiment to isolate the element, which he tested with silicon to find it burst into flame. “One can indeed make various hypotheses on the nature of the liberated gas; the simplest would be that we are in the presence of fluorine, but it would be possible, of course, that it might be a perfluoride of hydrogen, or even a mixture of hydrofluoric acid and ozone sufficiently active to explain such vigorous action as this gas exerts on crystalline silicon.” This conservative announcement was read to the Academy by Debray, for Moissan was not then a member. The president appointed a committee to check the discovery.* |
Blonde Paint Job
A blonde, wanting to earn some money, decided to hire herself out as a handyman-type and started canvassing a wealthy neighborhood. She went to the front door of the first house and asked the owner if he had any jobs for her to do.
"Well, you can paint my porch. How much will you charge?"
The blonde said, "How about 50 dollars?" The man agreed and told her that the paint and ladders that she might need were in the garage. The man's wife, inside the house, heard the conversation and said to her husband, "Does she realize that the porch goes all the way around the house?"
The man replied, "She should. She was standing on the porch."
A short time later, the blonde came to the door to collect her money. "You're finished already?" he asked.
"Yes," the blonde answered, "and I had paint left over, so I gave it two coats. "Impressed, the man reached in his pocket for the $50. "And by the way," the blonde added, "that's not a Porch, it's a Ferrari."
