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

Claude Shannon's "Entropy House"
Built in 1858, the house was constructed for Ellen Dwight, a great-granddaughter of a genius tinkerer of an earlier era, Thomas Jefferson. Originally seated on twelve acres, its design was inspired by Monticello. Encircled by “a three-sided verandah with segmental openings and chamfered posts,” the house was a stately three stories at the crest of a “broad expanse of lawn reaching down to the wooded shore of Upper Mystic Lake.” Toward the end of Shannon’s life, it was added to the N... 1 notes

Heritable IQ is Boosted by Environment, Just Like Height
hough it’s not easy to pinpoint the causes of the rise in IQ scores, it’s no paradox that a heritable trait can be boosted by changes in the environment. That’s what happened with height, a trait that also is highly heritable and has increased over the decades, and for some of the same reasons: better nutrition and less disease. Brains are greedy organs, consuming about a fifth of the body’s energy, and they are made of fats and proteins that are demanding for the body to produce. Fig... 1 notes

The Point
Behold yon miserable creature. That Point is a Being like ourselves, but confined to the non-dimensional Gulf. He is himself his own World, his own Universe; of any other than himself he can form no conception; he knows not Length, nor Breadth, nor Height, for he has had no experience of them; he has no cognizance even of the number Two; nor has he a thought of Plurality, for he is himself his One and All, being really Nothing. Yet mark his perfect self-contentment, and hence learn this lesso...Folksonomies: perspective dimensions

Shorter People Live Longer
The study was conducted to evaluate one aspect of the entropy theory of aging, which hypothesizes that aging is the result of increasing disorder within the body, and which predicts that increasing mass lowers life span. The first evaluation of the impact of human size on longevity or life span in 1978, which was based on data for decreased groups of athletes and famous people in the USA, suggested that shorter, lighter men live longer than their taller, heavier counterparts. In 1990, a study...
1 5 years on average. Suggesting the medical community's focus on encouraging parents to grow big children is misguided as it may be shortening their lifespans.

Kodak, Instagram, and Automation
Here’s a current example of the challenge we face... At the height of its power, the photography company Kodak employed more than 140,000 people and was worth $28 billion. They even invented the first digital camera. But today Kodak is bankrupt, and the new face of digital photography has become Instagram. When Instagram was sold to Facebook for a billion dollars in 2012, it employed only 13 people. Where did all those jobs disappear? And what happened to the wealth that all those middle-cl...Folksonomies: automation unemployment

Digiphrenia
In the digital universe, our personal history and its sense of narrative is succeeded by our social networking profile—a snapshot of the current moment. The information itself—our social graph of friends and likes—is a product being sold to market researchers in order to better predict and guide our futures. Using past data to steer the future, however, ends up negating the present. The futile quest for omniscience we looked at earlier in this chapter encourages us, particularly busines...Folksonomies: new media

Benjamin Franklin on Future of Science
The rapid progress true science now makes occasions my regretting sometimes that I was born so soon. It is impossible to imagine the Height to which may be carried, in a thousand years, the Power of Man over Matter...Agriculture may diminish its Labour and double its Produce; all Diseases may, by sure means, be prevented or cured, not even excepting that of Old Age, and our Lives lengthened at pleasure even beyond the antediluvian Standard. O that moral Science were in as fair a way of Improv...Folksonomies: prescience optimism

Benjamin Franklin's Forsight
I always rejoice to hear of your being still employed in experimental researches into nature, and of the success you meet with. The rapid progress true science now makes, occasions my regretting sometimes that I was born so soon: it is impossible to imagine the height to which may be carried, in a thousand years, the power of man over matter; we may perhaps learn to deprive large masses of their gravity, and give them absolute levity for the sake of easy transport. Agriculture may diminish it...He sees the future of science and the possibilities, but laments that it will not change the morals of man.

Copernicus' Hypothesis
After I had addressed myself to this very difficult and almost insoluble problem, the suggestion at length came to me how it could be solved with fewer and much simpler constructions than were formally used, if some assumptions (which are called axioms) were granted me. They follow in this order.
There is no one center of all the celestial circles or spheres.
The center of the earth is not the center of the universe, but only of gravity and of the lunar sphere.
All the spheres revolve about... 1 notes
