Processing Power to Chess Rating Ratio
50 here is what the Deep Thought team wrote about the relationship between search depth and chess strength in a 1989 article: The ascent of the brute-force chess machines back in the late 1970s made one thing crystal clear: there is a strong causal relationship between the search speed of a chess machine and its playing strength. In fact, it appeared from machine self-test games that every time a machine searches one extra ply, its rating increases by about 200-250 rating points. Since each...Folksonomies: computation processing power

The Great Lifespan Escape
At the time when the lines begin, in the mid-18th century, life expectancy in Europe and the Americas was around 35, where it had been parked for the 225 previous years for which we have data.3 Life expectancy for the world as a whole was 29. These numbers are in the range of expected life spans for most of human history. The life expectancy of hunter-gatherers is around 32.5, and it probably decreased among the peoples who first took up farming because of their starchy diet and the diseases ...05 MAR 2015 by ideonexus
We Have the Power to Accelerate Things to Near the Speed ...
Six years ago, in the distant Trisolaran stellar system, Trisolaris accelerated two hydrogen nuclei to near the speed of light and shot them toward the solar system. These two hydrogen nuclei, or protons, arrived at the solar system two years ago, then reached the Earth.Folksonomies: space travel speed of light

Proof that Objects Fall at the Same Rate
Salv. But, even without further experiment, it is possible to prove clearly, by means of a short and conclusive argument, that a heavier body does not move more rapidly than a lighter one provided both bodies are of the same material and in short such as those mentioned by Aristotle. But tell me, Simplicio, whether you admit that each falling body acquires a definite speed fixed by nature, a velocity which cannot be increased or diminished except by the use of force [violenza] or resistance....Galileo's proof is based completely on a thought-experiment, no observation necessary.

The World is a Function
Kakeru Seki: A fact is somehow related to another fact. Unless you understand these relationships, you won't be a real reporter. Noriko Hikima: True journalism! Kakeru Seki: Well, you majored in the humanities. Noriko Hikima: Yes! That's true--I've studied literature since I was in high school. Kakeru Seki: You havea lot of catching up to do, then. Let's begin with functions. Noriko Hikima: Fu...functions? Math? What? Kakeru Seki: When one thing changes, it influences another thing. A ...As a programmer I know that algorithms can relate to the real world, and since these algorithms are constructed in computers that ultimately run on bits and boolean logic, then the real world may be imagined to deconstruct to pure mathematics.

Science Manipulates Language to Make it More Precise
Let us consider two spheres moving in different di- rections on a smooth table. So as to have a definite picture, we may assume the two directions perpendicu- lar to each other. Since there are no external forces acting, the motions are perfectly uniform. Suppose, further, that the speeds are equal, that is, both cover the same distance in the same interval of time. But is it correct to say that the two spheres have the same velocity? The answer can be yes or no ! If the speedo- mete...The example is "velocity" which in common parlance is the same as "speed," but in science it means "speed and direction."

The Importance of the Velocity of Light
The velocity of light is one of the most important of the fundamental constants of Nature. Its measurement by Foucault and Fizeau gave as the result a speed greater in air than in water, thus deciding in favor of the undulatory and against the corpuscular theory. Again, the comparison of the electrostatic and the electromagnetic units gives as an experimental result a value remarkably close to the velocity of light–a result which justified Maxwell in concluding that light is the propagation...Folksonomies: speed of light light

The Marriage of Space and Time
The marriage of space and time that heralded the modern era began with the marriage, in 1864, of electricity and magnetism. This remarkable intellectual achievement, based on the cumulative efforts of great physicists such as AndrŽ-Marie Amp�re, Charles-Augustin de Coulomb, and Michael Faraday, was capped by the brilliant British physicist James Clerk Maxwell. He discovered that the laws of electricity and magnetism not only displayed an intimate relationship with one another but together ...Occurred when the relationship between electricity and magnetism was discovered.

Universal Intelligence Cannot Exist
We conclude that there cannot be a strongly cohesive network of communicating, unifying intelligences through the whole universe if (1) such galactic civilizations evolve upward from individual planetary societies and if (2) the velocity of light is indeed a fixed limit on the speed of information transmission, as special relativity requires (i.e., if we ignore such possibilities as using black holes for fast transport: See Chapter 39). Such a universal intelligence is a kind of god that cann...At best, aliens advanced enough to be gods could only exist at a galactic level.
