A man went into a local tavern and took a seat at the bar next to a women patron.
He turned to her and said, "This is a special day, I'm celebrating."
"What a coincidence," said the woman, "I'm celebrating, too". She clinked glasses with him and asked, "What are you celebrating?"
"I'm a chicken farmer," he replied. "For years all my hens were infertile, but today they're finally fertile."
"What a coincidence, the woman said. "My husband and I have been trying to have a child. Today, my gynecologist told me I'm pregnant! How did your chickens become fertile?" she asked.
"I switched cocks," he replied.
"What a coincidence," she said.

Wilhelm Pfeffer

Died 31 Jan 1920 at age 74 (born 9 Mar 1845).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.
