The teacher of the earth scien...

The teacher of the earth science class was lecturing on map reading. After explaining about latitude, longitude, degrees and minutes the teacher asked, "Suppose I asked you to meet me for lunch at 23 degrees, 4 minutes north latitude and 45 degrees, 15 minutes east longitude...?"
After a confused silence, a voice volunteered, "I guess you'd be eating alone."

Wilhelm Pfeffer

Born 9 Mar 1845; died 31 Jan 1920 at age 74.Wilhelm (Friedrich Philipp) Pfeffer was a German botanist whose work on osmotic pressure made him a pioneer in the study of plant physiology. With Julius von Sachs, he was a leader in systematizing the fundamentals of plant physiology. In 1877, while investigating cell metabolism, he devised a semi-permeable membrane for the study osmosis. By measuring osmotic pressure, a technique he developed, Pfeffer found that pressure depends on the size of the molecules that are too large to pass through the membrane. Thus, he had a method to measure the size of such giant molecules. However, he was unable to find a mathematical relationship to predict osmotic pressure, which was furthered by the work of van't Hoff.
