ENIAC was an early electronic digital computer built in the US by engineers J. Presper Eckert and John W. Mauchly. The massive ENIAC weighed 30 tons, filled an entire room, and used some 18,000 vacuum tubes, 70,000 resistors, and 10,000 capacitors. After its official unveiling in 1946, it was used to prepare artillery-shell trajectory tables and perform other military and scientific calculations. When ENIAC solved its first test problem, it made calculations for what? Discuss

Benny made his vaudeville debut playing the violin in 1912. After discovering a talent for comedy while in the navy, he returned to vaudeville as a comedian. He made his film debut in 1927 and appeared in 18 films between 1930 and 1945.

Waterboarding, a torture method that simulates drowning, has existed in various forms since the time of the Spanish Inquisition. Generally, water is poured over the face of an immobilized prisoner, inducing the gag reflex and mimicking sensations associated with drowning. The technique gained international attention in 2006, when reports surfaced charging the US with torturing detainees during the “War on Terror.” When CIA officers were waterboarded during training, how quickly did they break? 
Known as “the Edison Effect,” thermionic emission is the emission of electrons or ions by substances that are highly heated. The charged particles that are emitted are called thermions, and their number rapidly increases with the temperature of the substance. If the heated substance that emits thermions carries a charge, the thermions will carry the same charge. The effect was observed by Edison in 1883 when he was working on what invention?

Banks was a British naturalist, botanist, and patron of the sciences. After inheriting a large fortune in his early 20s, he began traveling extensively, collecting plant and natural history specimens. He outfitted and accompanied James Cook’s voyage around the world, during which time he collected many biological specimens that had never before been classified. His herbarium, one of the most important in existence, and library are now at the British Museum. What plant genus was named after him? 
Deinococcus radiodurans has been listed as the world’s toughest bacterium in The Guinness Book of World Records because of its extraordinary resistance to extreme conditions. It is the most radioresistant organism known to science and is able to rapidly repair damage to its genome. Many question how such a resilient bacterium could evolve on Earth, and some have suggested that the organism is actually of Martian origin. How do they propose the bacterium came to this planet?
