The strong young man at the co...

The strong young man at the construction site was bragging that he could outdo anyone in a feat of strength. He made a special case of making fun of one of the older workmen. After several minutes, the older worker had had enough. "Why don't you put your money where your mouth is," he said. "I will bet a week's wages that I can haul something in a wheelbarrow over to that outbuilding that you won't be able to wheel back." "You're on, old man," the braggart replied. "Let's see what you got." The old man reached out and grabbed the wheelbarrow by the handles. Then, nodding to the young man, he said, "All right. Get in."

Walter Noddack

Died 7 Dec 1960 at age 67 (born 17 Aug 1893).Walter Karl Friedrich Noddack was a German chemist who discovered the element rhenium (Jun 1925) in collaboration with his wife Ida Tacke. In 1922, he began a long search for undiscovered elements. After three years, the careful fractionation of certain ores yielded element 75, a rare heavy metallic element that resembles manganese. Named rhenium after the Rhine River, it was the last stable element to be discovered. Noddack is also remembered for arguing for a concept he called allgegenwartskonzentration or, literally, omnipresent concentration. This idea, reminiscent of Greek philosopher Anaxagoras, assumed that every mineral actually contained every element. The reason they could not all be detected was they existed in too small quantities.
