На английском:
Before electronic desktops ever existed, Alan Turing estimated their strength and versatility...but additionally proved what desktops may possibly by no means do.
In a unprecedented and finally tragic existence that opened up like a singular, Turing helped holiday the German Enigma code to show the tide of worldwide struggle II, later speculated on synthetic intelligence, fell sufferer to the homophobic witchhunts of the early Nineteen Fifties, and dedicated suicide on the age of forty-one. but Turing is most renowned for an eerily prescient 1936 paper within which he invented an imaginary computing computing device, explored its features and intrinsic obstacles, and confirmed the rules of modern day programming and computability.
This soaking up booklet expands Turings now mythical 36-page paper with wide annotations, interesting old context, and page-turning glimpses into his inner most existence. From his use of binary numbers to his exploration of thoughts that todays programmers will realize as RISC processing, subroutines, algorithms, and others, Turing foresaw the long run and helped to mildew it. In our post-Turing global, every thing is a Turing desktop — from the main subtle desktops we will be able to construct, to the barely algorithmic tactics of the human brain, to the information-laden universe during which we are living.

Example text

This is now known as the Russell Paradox, and became the latest of several paradoxes that have plagued mathematicians for at least two millennia. Russell later made an analogy with a town barber who shaves all those who do not shave themselves. Who shaves the barber? Russell wrote a letter to Frege inquinng about the set that contains all sets that do not contain themselves,15 and Frege was devastated. He quickly wrote an appendix to the second volume of Grundgesetze der Arithmetik, but the problem could not be fixed.

For example, { 1, 2, 3, 4 } is the set of the first four positive integers. The elements in a set are unique. Two 4s in the same set isn't allowed, for example. The order of the elements in a set doesn't matter. The set {4, 1, 3, 2 } is identical to the previous one. The number of elements in a set is called the cardinal number of the set, or the set's cardinality. The cardinality of the finite set shown above is 4. Sets that have the same cardinality are said to be equivalent. Some sets have a finite cardinality; others have an infinite cardinality.

All these sets have different cardinalities. Cantor speculated that the cardinality of the continuum was the next higher transfinite number after ~o, which is the transfinite number he called ~l' This speculation is called Cantor's continuum hypothesis, and it can be expressed mathematically like this: ~l = 2~o Cantor struggled to prove his hypothesis, but was never able to do so. The problem is that there could be some other transfinite number between ~o and the cardinality of the continuum. Regardless, the profound implication of all this is that the cardinality of enumerable sets is not only smaller than the cardinality of the continuum ~o < 2~o but much, much, much, much, much smaller: ~o « « « « « « « « « « « « < 2~o lOll may also seem as if we've stumbled on a method to enumerate all the real numbers between 0 and 1 The pattern is already eVIdent - the first digit after the penod alternates between 0 and 1, the second digit alternates at half the speed, and so on - and we could easily continue this list as long as we want The fallacy, however, is that the list WIll never contain a transcendental number Every number in the list has a finite number of non-zero digits after the penod The Irrational and the Transcendental 33 The only difference between the continuum and enumerable sets is the inclusion of transcendental numbers.
