David Hilbert
David Hilbert (; ; 23 January 1862 – 14 February 1943) was a German mathematician and philosopher of mathematics and one of the most influential mathematicians of his time. Hilbert discovered and developed a broad range of fundamental ideas including invariant theory, the calculus of variations, commutative algebra, algebraic number theory, the foundations of geometry, spectral theory of operators and its application to integral equations, mathematical physics, and the foundations of mathematics (particularly proof theory). He adopted and defended Georg Cantor's set theory and transfinite numbers. In 1900, he presented a collection of problems that set a course for mathematical research of the 20th century. Hilbert and his students contributed to establishing rigor and developed important tools used in modern mathematical physics. He was a cofounder of proof theory and mathematical logic.

Charlie McCarthy
Charlie McCarthy was a dummy partner of American ventriloquist Edgar Bergen. Charlie was part of Bergen's act as early as high school, and by 1930 was attired in a top hat, tuxedo and monocle. The character was so well known that his popularity exceeded that of his performer, Bergen. History Charlie's personality was that of a mischievous little boy, who could wisecrack, misbehave and flirt shamelessly in a way that Bergen could not. Bergen's original dummy was built by carpenter/dummy-maker Theodore Mack, and was later rebuilt by Frank Marshall. A 1938 magazine article reported that “When Edgar Bergen was a high school student in Chicago in the post-war WIperiod, he got the notion that he wanted a dummy so that he could become a ventriloquist. He came to Mr. harlieMack’s workshop who assigned rankMarshall to the problem. Bergen wanted a fresh Irish kid, resembling a newsboy that he knew, and the present Charlie McCarthy was made and sold to Bergen for $35 in 1923. However ...

Edgar Bergen
Edgar John Bergen (né Berggren; February 16, 1903 – September 30, 1978) was an American ventriloquist, comedian, actor, vaudevillian and radio performer. He was best known for his characters Charlie McCarthy and Mortimer Snerd. Bergen pioneered modern-day ventriloquism and has been described by puppetry organization UNIMA as the “quintessential ventriloquist of the 20th century”. He was the father of actress Candice Bergen. Early life Bergen was born in Chicago, one of five children and the younger of two sons of Swedish immigrants Nilla Svensdotter (née Osberg) and Johan Henriksson Berggren. He lived on a farm near Decatur, Michigan until he was four, when his family returned to Sweden, where he learned the language. After his family had returned to Chicago, when he was eleven, he taught himself ventriloquism from a pamphlet called "The Wizard's Manual". He attended Lake View High School. After his father died, when Edgar was 16, he went out to work as an ap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, measure distances ( ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and sodar (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low ( infrasonic) to e ...

Submarine
A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or informally to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, or to medium-sized or smaller vessels (such as the midget submarine and the wet sub). Submarines are referred to as ''boats'' rather than ''ships'' regardless of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and submarines were adopted by several navies. They were first used widely during World War I (1914–1918), and are now used in many navy, navies, large and small. Their military uses include: attacking enemy surface ships (merchant and military) or other submarines; aircraft carrier protection; Blockade runner, blockade running; Ballistic missile submarine, nuclear deterrenc ...
