The.Universal.History.of.Computing.From.the. A few devices are worth mentioning though, like some mechanical aids to computing, which were very successful and survived for centuries until the advent of the electronic calculator, like the Sumerian abacus, designed . The Universal History of Computing: From the Abacus to the Quantum Computer. I might be wrong but my idea of a Turing machine is it was kind of a generalization and in a way simplification of already existing mechanical computers in that it didn't really think of one big set of input that determines how dozens of parts of a machine work and generates its output. Retrieved March 18, 2009, from The Museum of HP Calculators Web site: http://www.hpmuseum.org/sliderul.htm. The Blog of Scott Aaronson Quantum computers are not known to be able to solve NP-complete problems in polynomial time, and can be simulated classically with exponential slowdown. While some computers may have strange concepts ???instructions??? and ???output??? (see quantum computing), modern computers based on the von Neumann architecture often have machine code in the form of an imperative programming language. The Universal History of Computing: From the Abacus to Quantum Computing gives a grand title to a grand subject, and Ifrah makes good on his promise of universality by leaping far back in time and spanning all the inhabited continents.If his scope is vast, his Readers will hang on the stories of 19th-century inventors converging on multiplication machines and other, more general "engines", and better understand the roots of biological and quantum computation. It was more of a Even von Neuman's idea of storing the ???algorithm??? in the memory of the computer instead of hardwiring it comes from the notion of Universal Turing machine.
