The Clock as the Mother of All Machines

PRECISELY because the clock did not start as a practical tool shaped for a single purpose, it was destined to be the mother of machines. The clock broke down the walls between kinds of knowledge, ingenuity, and skill, and clockmakers were the first consciously to apply the theories of mechanics and physics to the…

Heat is a Substance

We recognize in the concept of heat which appears here a similarity to other physical concepts. Heat is, according to our view, a substance, such as mass in mechanics. Its quantity may change or not, like money put aside in a safe or spent. The amount of money in a safe will remain unchanged so long as the safe…

Skepticism in Science has Grown

In 1982, polls showed that 44 percent of Americans believed God had created human beings in their present form. Thirty years later, the fraction of the population who are creationists is 46 percent. In 1989, when “climate change” had just entered the public lexicon, 63 percent of Americans understood it was a problem…

The Siren Server

A Siren Server, as I will refer to such a thing, is an elite computer, or coordinated collection of computers, on a network. It is characterized by narcissism, hyperamplified risk aversion, and extreme information asymmetry. It is the winner of an all-or-nothing contest, and it inflicts smaller all-or-nothing contests…

Sociological Metaphors for the Public

Social science and philosophy have generated a vast number of other metaphorical descriptions of the public, rooted in different and often scientific perspectives on systematicity and relation. These are technologies in the broad sense that they enable different kinds of questions to be asked. An account of these…

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…

Odd Sympathy

Laid up in bed during a brief illness and idly watching two clocks mounted in one case, Huygens noticed something strange: No matter how the pendulums started out, eventually they always ended up swinging in exactly opposite directions. Huygens wondered whether this odd sympathy might solve the longitude problem…

Nature is Intrinsically Probabilistic

Here are the circumstances: source, strong light source; tell me, behind which hole will I see the electron? You say, 'Well, the reason you can't tell through which hole you're going to see the electron is, it's determined by some very complicated things back here: if I knew enough about that electron - it has…

Overview of Optical Networks

Optical fibers can transmit digitized light signals over long distances because of the purity of glass fiber combined with improved electronics technology. With some acceptable transmission loss, low interference, and high-bandwidth potential, an optical fiber is almost an ideal transmission medium. Optical…

The Mathematical Image

The proof is elegant and the result profound. Still, it is typical mathematics; so, it’s a good example to reflect upon. In doing so, we will begin to see the elements of the mathematical image, the standard conception of what mathematics is. Let’s begin a list of some commonly accepted aspects. By ‘commonly accepted’…

WWW Makes the Improbable Normal

Cops, emergency room doctors, and insurance actuarists all know it. They realize how many crazy impossible things happen all the time. A burglar gets stuck in a chimney, a truck driver in a head on collision is thrown out the front window and lands on his feet, walks away; a wild antelope knocks a man off his bike; a…

Dyson Spheres

The purpose of this report is to point out other possibilities which ought to be considered in planning any serious search for evidence of extraterrestrial beings. We start from the notion that the time scale for industrial and technical development of these beings is likely to be very short in comparison with the…

You want a physicist to speak at your funeral

You want a physicist to speak at your funeral. You want the physicist to talk to your grieving family about the conservation of energy, so they will understand that your energy has not died. You want the physicist to remind your sobbing mother about the first law of thermodynamics; that no energy gets created in the…

Entropy as a Purpose in Life

To the best of our knowledge, these tool use puzzle and social cooperation puzzle results represent the rst successful completion of such standard animal cognition tests using only a simple physical process. The remarkable spontaneous emergence of these sophisticated behaviors from such a simple physical process…

Man Becomes Acquainted With the Laws of the Universe

Rational mechanics soon became a vast and profound science. The true laws of the collision of bodies, respecting which Descartes was deceived, were at length known. Huyghens discovered the laws of circular motions; and at the same time he gives a method of determining the radius of curvature for every point of a given…

Progress of Science in the Eighth Epoch

The march of the sciences is rapid and brilliant. The Algebraic language becomes generalized, simplified and perfected, or rather it is now only that it was truly formed. The first foundations of the general theory of equations are laid, the nature of the solutions which they give is ascertained, and those of the…
