After weeks of getting the cold shoulder from his wife, the unhappy husband finally confronted her.
'Admit it, Linda. The only reason you married me is because my grandfather left me $10 million.'
'Don't be ridiculous,' she replied. 'I don't care who left it to you.'
Atomic chain reactionIn 1942, the first self-sustained nuclear chain reaction was demonstrated in Chicago, Illinois. At the University of Chicago, Enrico Fermi and his team achieved the world's first artificial nuclear chain reaction, in a makeshift lab underneath the University's football stands at Stagg Field. Work on the experimental pile had begun on 16 Nov 1942. It was a prodigious effort. Physicists and staffers, working around the clock, built a lattice of 57 layers of uranium metal and uranium oxide embedded in graphite blocks. A wooden structure supported the graphite pile. The chain reaction was part of the Manhattan Project, a secret wartime project to develop nuclear weapons, which initiated the modern nuclear age. This was a discovery that changed the world. |
