It only says that if something physical is a computing system, then the functions it computes are Turing-computable.
The Open Source Robotics Foundation, based in Mountain View, California, created a software-based physics simulator that computes and displays what happens as mock robots move through a computer-based world.
A number is Turing-computable if there exists a Turing machine which starting from a blank tape computes an arbitrarily precise approximation to that number.
What this all computes to is that Cameron needs a lot to go his way in the next three weeks.
Based on this, the Baltics should have been able to manage average annual growth between about 3.0% and about 5.5%, depending on which Baltic and which exchange-rate adjustment you're using (Mr Subramanian presents a table in his post giving the numbers he computes).
It does not learn to understand voice; it computes probabilities.To launch the service Google needed an existing voice-recognition system, so it licensed software from Nuance, a leader in the field.
The so-called functional language Lisp computes with symbolic expressions rather than numbers; the logical language Prolog works by making logical statements about objects.Lisp and Prolog still have a loyal following in research circles, but their impact elsewhere has been modest.
A free service that almost instantaneously computes the answers to complex questions such as the ratio between exports and imports in Ghana (or any other country) over the past ten years is indeed novel, and may serve to help democratise expert knowledge.
Mathematica is hugely popular among engineers, scientists and financial analysts, and its success gave Dr Wolfram the financial security to continue to do his own thing as an independent scientist and researcher.His most recent venture is Wolfram Alpha, a website launched in 2009 that he describes as a "knowledge engine that computes answers to questions".
The Cleveland Fed computes up median and "16% trimmed-mean" CPI.These different indexes provide a check on each other, and are often good at highlighting particular sorts of trends in the data.
At each stage, it computes the changing sentiment of the sentence.
