What did John von Neumann do for math?
Von Neumann’s significant contribution to mathematical economics was the minimax theorem of 1928. This theorem establishes that in certain zero sum games with perfect information, there exists a strategy for each player which allows both players to minimize their maximum losses.
When did von Neumann invent?
After the war, in 1945, von Neumann drafted a report and machine description that led to the construction of the EDVAC, or Electronic Discrete Variable Automatic Computer. Von Neumann’s report marked the first conceptualization of the stored-program computer.
What is John von Neumann famous for?
John von Neumann is perhaps best known known for his work in the early development of computers: As director of the Electronic Computer Project at Princeton’s Institute for Advanced Study (1945-1955), he developed MANIAC (mathematical analyzer, numerical integrator and computer), which was at the time the fastest …
What did Pascal invented?
Pascal’s calculator
Mechanical calculatorAdding machine
Blaise Pascal/Inventions
Pascal invented the first digital calculator to help his father with his work collecting taxes. He worked on it for three years between 1642 and 1645. The device, called the Pascaline, resembled a mechanical calculator of the 1940s.

Where Did game theory originated?
In fact, game theory was originally developed by the Hungarian-born American mathematician John von Neumann and his Princeton University colleague Oskar Morgenstern, a German-born American economist, to solve problems in economics.
What are the contributions of John von Neumann in mathematics?
Von Neumann produced a staggering succession of pivotal papers in logic, set theory, group theory, ergodic theory, and operator theory. Herman Goldstine and Eugene Wigner noted that, of all the principal branches of mathematics, it was only in topology and number theory that von Neumann failed to make an important contribution.
How do you generate a von Neumann algebra?
Similarly, a von Neumann algebra is generated by its projections; this is a consequence of the spectral theorem for self-adjoint operators . The projections of a finite factor form a continuous geometry . A von Neumann algebra N whose center consists only of multiples of the identity operator is called a factor.
What are projections in von Neumann algebra?
Operators E in a von Neumann algebra for which E = EE = E* are called projections; they are exactly the operators which give an orthogonal projection of H onto some closed subspace. A subspace of the Hilbert space H is said to belong to the von Neumann algebra M if it is the image of some projection in M.
What is John von Neumann’s full name?
John von Neumann, original name János Neumann (born December 28, 1903, Budapest, Hungary—died February 8, 1957, Washington, D.C., U.S.), Hungarian-born American mathematician. As an adult, he appended von to his surname; the hereditary title had been granted his father in 1913.
