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.

Graduation Speech

When my son graduated from high school, he had to give a speech. He began by reading from his prepared text.
'I want to talk about my mother and the wonderful influence she has had on my life,' he told the audience. 'She is a shining example of parenthood, and I love her more than words could ever do justice.'
At this point he seemed to struggle for words. After a pause, he looked up with a sly grin and said, 'Sorry, but it's really hard to read my mother's handwriting.'
