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

Where are Proponents of the Enlightenment?
The place of the Enlightenment in public debate has all but disappeared. Renowned philosophers who do engage with criticism of the Enlightenment, such as Jürgen Habermas and Charles Taylor, do not catch the imagination of a wide public in the way Foucault did 40 years ago. Even the great scientists of NASA and Caltech, heirs of Isaac Newton, armed with massive modern reams of data, cannot sway the majority of the American public into believing that global warming is man-made. Instead of majo... 1 notes

Synchronicity in Science
The famous Canadian physician William Osler once wrote, “In science the credit goes to the man who convinced the world, not to the man to whom the idea first occurs.” When we examine discoveries in science and mathematics, in hindsight we often find that if one scientist did not make a particular discovery, some other individual would have done so within a few months or years of the discovery. Most scientists, as Newton said, stood on the shoulders of giants to see the world just a bit fa... 1 notes

Einstein's "Biggest Blunder"
For much of the modern era, scientists followed Nicolaus Copernicus, Galileo Galilei, and Isaac Newton in believing the cosmos to be eternal and unchanging. But in 1917, when Albert Einstein applied his theory of relativity to space-time as a whole, his equations implied that the universe could not be static; it must be either expanding or contracting. This struck Einstein as grotesque, so he added to his theory a fiddle factor called the "cosmological constant" that eliminated the implicatio...
1 The story of how Einstein's belief in a static Universe prompted him to introduce a fudge-factor in his Theory of Relativity, the Cosmological Constant.

Science Rewards Those Who Disprove
There is a reward structure in science that is very interesting: Our highest honors go to those who disprove the findings of the most revered among us. So Einstein is revered not just because he made so many fundamental contributions to science, but because he found an imperfection in the fundamental contribution of Isaac Newton. 1 notes
notesEinstein is famous for finding a flaw in Newton's contributions.

Newton on the Power of Gravity
As he sat alone in a garden, he [Isaac Newton in 1666, age 24] fell into a speculation on the power of gravity; that as this power is not found sensibly diminished at the remotest distance from the centre of the earth to which we can rise, neither at the tops of the loftiest buildings, nor even on the summits of the highest mountains, it appeared to him reasonable to conclude that this power must extend much further than was usually thought: why not as high as the moon? said he to himself; an... 1 notes

Newton Was the Last Magi
Newton was not the first of the age of reason. He was the last of the magicians, the last of the Babylonians and Sumerians ... Isaac Newton, a posthumous child born with no father on Christmas Day, 1642, was the last wonder child to whom the Magi could do sincere and appropriate homage... Why do I call him a magician? Because he looked on the whole universe and all that is in it as a riddle, as a secret which could be read by applying pure thought to certain evidence, certain mystic clues whi... 1 notes

The Foundation of Science, Not the Periphery, Is Where th...
A number of years ago, when I was a freshly-appointed instructor, I met, for the first time, a certain eminent historian of science. At the time I could only regard him with tolerant condescension.
I was sorry of the man who, it seemed to me, was forced to hover about the edges of science. He was compelled to shiver endlessly in the outskirts, getting only feeble warmth from the distant sun of science- in-progress; while I, just beginning my research, was bathed in the heady liquid heat up a... 1 notes

Many Great Scientific Minds Were Religious
A great many leading lights of the scientific revolution and the Enlightenment-Nicolaus Copernicus, Francis Bacon, Rene Descartes, Johannes Kepler, Galileo Galilei, Isaac Newton, Robert Boyle—were distinctly religious and viewed science as a better means of understanding God's creation and the laws governing it. 1 notes
