Diesel engine patent

In 1893, Rudolf Diesel received a German patent for the diesel engine. His engine burns fuel oil rather than gasoline, and uses high compressed of the gases in the cylinder rather than a spark to ignite the fuel. Diesel engines were used widely in Europe for their efficiency and power, and are still used today in most heavy industrial machinery. Diesel cars never caught on in the U.S., partly because the diesel engine's greater efficiency is counter-balanced by its higher emissions of soot, odor, and air pollutants. However, some environmentalists argue that in spite of the diesel engine's exhaust pollution, its fuel efficiency may make it more environmentally sound than the gasoline engine in the long run.

Casino Money

A man spent a weekend gambling in Las Vegas casinos, and he won $100,000. He didn't want anyone to know about it, so whan he came back home, he immediately went out to the backyard of his house, dug a hole and planted the money in it.
The next morning he walked outside and found only an empty hole. He noticed footsteps leading from the hole to the house next door, which was owned by a deaf-mute. On the same street lived a professor who understood sign language and was a friend of the deaf man. Grabbing his pistol, the enraged man went to awaken the professor and dragged him to the deaf man's house. He screamed at the professor:
"You tell this guy that if he doesn't give me back my money I'll kill him!"
The professor conveyed the message to his friend, and his friend replied in sign language: "I hid it in my backyard, underneath the cherry tree."

The professor turned to the man with the gun and said: "He's not going to tell you. He said he'd rather die first."
