Asimov Story on Computation
■ N 1958, American science fiction legend Isaac Asimov wrote a very short story called "The Feeling of Power." In it, lowly technician MyI ron Aub discovers that he is capable of duplicating the work of his computer by multiplying two numbers together on a piece of paper. Amazing! This miraculous discovery makes its way up the chain of command, where the generals and politicians are stunned by Aub's black magic. The top general is intrigued by the possibility that human calculations could g...02 MAR 2019 by ideonexus
The Anthropic Principle
As an example of the power of the Anthropic Principle, consider the number of directions in space. It is a matter of common experience that we live in three-dimensional space. That is to say, we can represent the position of a point in space by three numbers. For example, latitude. longitude and height above sea level. But why is space three-dimensional? Why isn't it two, or four, or some other number of dimensions, hke in science fiction? In fact, in M-theory space has ten dimensions (as wel...Folksonomies: anthropic principle

All Failures are the Result of Insufficient Knowledge
Optimism (in the sense that I have advocated) is the theory that all failures—all evils—are due to insufficient knowledge. . . . Problems are inevitable, because our knowledge will always be infinitely far from complete. Some problems are hard, but it is a mistake to confuse hard problems with problems unlikely to be solved. Problems are soluble, and each particular evil is a problem that can be solved. An optimistic civilization is open and not afraid to innovate, and is based on traditi...27 JUL 2018 by ideonexus
We Need Play to Learn the Rules of the Game for the Civil...
The Real Significance of Play.—This scheme is, doubtless, imperfect, as critics of Groos’s book have taken occasion to point out, but the idea which underlies it all is a most suggestive and illuminating one, when rightly understood. In his latest work on the play of man, which has recently appeared, Groos makes clear this point (253, p. 492), when he observes: ‘I presuppose everywhere the existence of innate impulses (Triebe), and assume that these have only led to play-exercise (Spiel...24 JAN 2015 by ideonexus
Darwin and the Origins of Life
There is a curious parallelism between Darwin's twenty-year delay in publishing his theory of evolution and Newton's {102} twenty-year delay in publishing the Principia. And Newton's refusal to publish his cosmological speculations finds a parallel in Darwin's silence concerning the problem of the origin of life. If we are to understand in general terms the place of life in the universe, we must also understand life's origin. Darwin explicitly excluded the origin of life from the scope of ...24 JAN 2015 by ideonexus
Error Catastrophe
The central problem for any theory of the origin of replication is the fact that a replicative apparatus has to function almost perfectly if it is to function at all. If it does not function perfectly, it will give rise to errors in replicating itself, and the errors will accumulate from generation to generation. The accumulation of errors will result in a progressive deterioration of the system until it is totally disorganized. This deterioration of the replicative apparatus is called the "e...Folksonomies: biology replication

The Comet Loss Cone
To understand why comet showers occur, we go back to the Oort Cloud. The theory of comet showers was worked out by Jack Hills, an American physicist now at Los Alamos. He realized that the movements of the comets in the Oort Cloud are not entirely random. Comets in the cloud are generally moving in random directions, but if a comet happens to be moving in an orbit almost exactly toward the Sun, it will not survive for long. A comet in an orbit coming close to the Sun may get boiled away and d...Folksonomies: astronomy astrophysics

12X Spiral
The theory is that numbers are self-organized around the smallest, most highly composite number, 12. The number 12 and many of its multiples (24, 36, 48, 60, etc.) are HCNs: highly composite numbers (with lots of divisors), which are extremely useful for measuring and proportions. Why are there 12 eggs in a carton, 12 inches in a foot, 12 months in a year, 24 hours in a day, 360 degrees in a circle, 60 seconds in minute? Because highly composite numbers can be divided evenly in many ways. For...Building a spiral around a clock, with 12-segments in the rotation, puts multiples of 3 at {3,6,9,12}, multiples of at {4,8,12}, multiples of 2 at {2,4,6,8,10,12}, and primes at {1,5,7,11}.

Knowledge VS Understanding
Knowledge understanding The facts The meaning of the facts A body of coherent facts The “theory” that provides coherence and meaning to those facts Verifiable claims Fallible, in-process theories Rightor wrong A matter of degree or sophistication I know something to be true I understand why it is, what makes it knowledge I respond on cue with what I know I judge when to and when not to use what I know02 JAN 2014 by ideonexus
"No investigation no right to speak"
Everyone engaged in practical work must investigate conditions at the lower levels. Such investigation is especially necessary for those who know theory but do not know the actual conditions, for otherwise they will not be able to link theory with practice. Although my assertion, "No investigation no right to speak", has been ridiculed as "narrow empiricism", to this day I do not regret having made it; far from regretting it, I still insist that without investigation there cannot possibly be ...Folksonomies: empiricism
