A linguistics professor was lecturing to his 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," he pointed out, "there is no language wherein a double positive can form a negative."
A voice from the back of the room piped up, "Yeah. Right."
Artturi Ilmari VirtanenBorn 15 Jan 1895; died 11 Nov 1973 at age 78.Finnish biochemist whose investigations directed toward improving the production and storage of protein-rich green fodder, vitally important to regions characterized by long, severe winters, brought him the Nobel Prize for Chemistry in 1945. The AIV method, named for his initials, was storing green fodder in an acid medium to prevent spoilage and retain nutritious nitrogenous material. He found that a mixture of hydrochloric and sulfuric acid was adequate as long as its strength was kept within certain precise limits (a pH of about four). In 1929, he found that cows fed such silage gave milk indistinguishable in taste from that of cows fed on normal fodder, while as rich in vitamins A and C. |
