There is no language wherein a double positive can form a negative

A linguistics professor was lecturing to his English class one day. “In English,” he said, “a double negative forms a positive.

In some languages, though, such as Russian, a double negative is still a negative.

However, there is no language wherein a double positive can form a negative.”

A voice from the back of the room piped up, "Yeah, right."

Edward Farber

Born 22 Jul 1914; died 22 Jan 1982 at age 67.Edward Rolke Farber was an American inventor who devised a portable, battery-operated stroboscopic flash unit for still cameras (1937) that effectively “stopped action.”He began his career as a photojournalist on the staff of the Milwaukee Journal. After studying electrical engineering at Northwestern University, Farber went on to design flash equipment for the U.S. Army during World War II, and then established his own electronic-flash manufacturing firm. He was a good friend and collaborator of Harold Edgerton and developed the first practical portable strobe flash for news photographers. In 1942, the Milwaukee Journal became the first newspaper to furnish all of its photographers with the portable flash. Weighing only 13.5 pounds, it was a considerable improvement over the 90-pound units photographers used prior to Farber's invention. He sold his Strobe Research firm in 1954. He was a photographic adviser to the U.S. Government during its intercontinental ballistic missile testing program in the late 1950's.
