MANIAC I
__NOTOC__ The MANIAC I (''Mathematical Analyzer Numerical Integrator and Automatic Computer Model I'') was an early computer built under the direction of Nicholas Metropolis at the Los Alamos Scientific Laboratory. It was based on the von Neumann architecture of the IAS, developed by John von Neumann. As with all computers of its era, it was a one-of-a-kind machine that could not exchange programs with other computers (even the several other machines based on the IAS). Metropolis chose the name MANIAC in the hope of stopping the rash of silly acronyms for machine names, although von Neumann may have suggested the name to him. The MANIAC weighed about . The first task assigned to the Los Alamos Maniac was to perform more precise and extensive calculations of the thermonuclear process. In 1953, the MANIAC obtained the first equation of state calculated by modified Monte Carlo integration over configuration space. In 1956, MANIAC I became the first computer to defeat a human being ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

MANIAC II
The MANIAC II (''Mathematical Analyzer Numerical Integrator and Automatic Computer Model II'') was a first-generation electronic computer, built in 1957 for use at Los Alamos Scientific Laboratory. MANIAC II was built by the University of California and the Los Alamos Scientific Laboratory, completed in 1957 as a successor to MANIAC I. It used 2,850 vacuum tubes and 1,040 semiconductor diodes in the arithmetic unit. Overall it used 5,190 vacuum tubes, 3,050 semiconductor diodes, and 1,160 transistors. It had 4,096 words of memory in Magnetic-core memory (with 2.4 microsecond access time), supplemented by 12,288 words of memory using Williams tubes (with 15 microsecond access time). The word size was 48 bits. Its average multiplication time was 180 microseconds and the average division time was 300 microseconds. By the time of its decommissioning, the computer was all solid-state, using a combination of RTL, DTL and TTL. It had an array multiplier, 15 index registers, 16K of 6-m ...

List Of Vacuum Tube Computers
Vacuum-tube computers, now called first-generation computers, are programmable digital computers using vacuum-tube logic circuitry. They were preceded by systems using electromechanical relays and followed by systems built from discrete transistors. Some later computers on the list had both vacuum tubes and transistors.

Markov Chain Monte Carlo
In statistics, Markov chain Monte Carlo (MCMC) methods comprise a class of algorithms for sampling from a probability distribution. By constructing a Markov chain that has the desired distribution as its equilibrium distribution, one can obtain a sample of the desired distribution by recording states from the chain. The more steps that are included, the more closely the distribution of the sample matches the actual desired distribution. Various algorithms exist for constructing chains, including the Metropolis–Hastings algorithm. Application domains MCMC methods are primarily used for calculating numerical approximations of multi-dimensional integrals, for example in Bayesian statistics, computational physics, computational biology and computational linguistics. In Bayesian statistics, the recent development of MCMC methods has made it possible to compute large hierarchical models that require integrations over hundreds to thousands of unknown parameters. In rare even ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Marjorie Devaney
Marjorie Ann "Marge" Jones Devaney (March 3, 1931 – September 20, 2007) was an American mathematician, electrical engineer, and computer scientist who assisted in the development of the MANIAC I (Mathematical Analyzer Numerical Integrator And Computer) computer in 1951 as a member of the Theoretical Division at the Los Alamos National Laboratory, making her one of world's earliest computer programmers.

Pentomino
Derived from the Greek word for ' 5', and "domino", a pentomino (or 5-omino) is a polyomino of order 5, that is, a polygon in the plane made of 5 equal-sized squares connected edge-to-edge. When rotations and reflections are not considered to be distinct shapes, there are 12 different '' free'' pentominoes. When reflections are considered distinct, there are 18 '' one-sided'' pentominoes. When rotations are also considered distinct, there are 63 ''fixed'' pentominoes. Pentomino tiling puzzles and games are popular in recreational mathematics. Usually, video games such as ''Tetris'' imitations and ''Rampart'' consider mirror reflections to be distinct, and thus use the full set of 18 one-sided pentominoes. Each of the twelve pentominoes satisfies the Conway criterion; hence every pentomino is capable of tiling the plane. Each chiral pentomino can tile the plane without being reflected. History The earliest puzzle containing a complete set of pentominoes appeared in Henry D ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Dana Scott
Dana Stewart Scott (born October 11, 1932) is an American logician who is the emeritus Hillman University Professor of Computer Science, Philosophy, and Mathematical Logic at Carnegie Mellon University; he is now retired and lives in Berkeley, California. His work on automata theory earned him the Turing Award in 1976, while his collaborative work with Christopher Strachey in the 1970s laid the foundations of modern approaches to the semantics of programming languages. He has worked also on modal logic, topology, and category theory. Early career He received his B.A. in Mathematics from the University of California, Berkeley, in 1954. He wrote his Ph.D. thesis on ''Convergent Sequences of Complete Theories'' under the supervision of Alonzo Church while at Princeton, and defended his thesis in 1958. Solomon Feferman (2005) writes of this period: After completing his Ph.D. studies, he moved to the University of Chicago, working as an instructor there until 1960. In 1959, he pu ...

Mary Tsingou
Mary Tsingou (married name: Mary Tsingou-Menzel; born October 14, 1928) is an American physicist and mathematician of Greek descent. She was one of the first programmers on the MANIAC computer at Los Alamos National Laboratory and is best known for having coded the celebrated computer experiment with Enrico Fermi, John Pasta, and Stanislaw Ulam which became an inspiration for the fields of chaos theory and scientific computing and was a turning point in soliton theory. Life Mary Tsingou was born in Milwaukee, Wisconsin, her Greek parents having moved to the US from Bulgaria. In the aftermath of the Great Depression, the family left the US to spend several years in Bulgaria. In 1940, they returned to the US, where Tsingou attended high school and college. She graduated in mathematics and education in 1951 from the University of Wisconsin. She then studied at the University of Michigan, receiving a master's degree in mathematics in 1955. In 1958, she married Joseph Menzel. Car ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
