Newton Saw that the Moon is Falling
One had to be a Newton to see that the Moon is falling, when everyone sees that it doesn't. - Paul Valery

The Mesh of Science
I do not think that truth becomes more primitive if we pursue it to simpler facts. For no fact in the world is instant, infinitesimal and ultimate, a single mark. There are, I hold, no atomic facts. In the language of science, every fact is a field—a crisscross of implications, those that lead to it and those that…
Evolution from Inner-Philsophy to Natural Philosophy
There have always been two ways of looking for truth. One is to find concepts which are beyond challenge, because they are held by faith or by authority or the conviction that they are self-evident. This is the mystic submission to truth which the East has chosen, and which dominated the axiomatic thought of the…
Science is the Knot Tying it all together
The creation was a concept—a connected set of concepts. There was the concept of a universal gravitation-reaching beyond the tree tops and the air to the ends of space. There was the concept of other universal forces in space, which ti to pull the moon away as a whirling stone pulls away fro: its string. And there was…
It Wasn't the Apple that Newton Used to Discover Gravity
Science finds order and meaning in our experience, and sets about this in quite a different way. It sets about it as New¬ ton did in the story which he himself told in his old age, and of which the schoolbooks give only a caricature. In the year 1665, when Newton was twenty-two, the plague broke out in southern…
Science is About Finding Likeness
All science, is the searchjnr njQJty in hidden likenesses. The search may be on a grand scale, as in the modern theories which try to link the fields of gravitation and electromagnetism. But we do not need to be browbeaten by the scale of science. There are discoveries to be made by snatching a small likeness from the…
The Natural Law Argument
We now find that a great many things we thought were natural laws are really human conventions. You know that even in the remotest depths of stellar space there are still three feet to a yard. That is, no doubt, a very remarkable fact, but you would hardly call it a law of nature. And a great many things that have…
Life as the Reduction of Entropy
During the present century a few physicists have tried to define life. Bernal, Schroedinger, and Wigner all came to the same general conclusion, that life is a member of the class of phenomena which are open or continuous systems able to decrease their internal entropy at the expense of substances or free energy taken…
Lovelock Gets the Second Law of Thermodynamics Wrong
Let us again look at the laws of thermodynamics. It is true that at first sight they read like the notice at the gait of Dante's Hell; but in fact, tough as they are and although like income tax they cannot without penalyt be evaded, they can with forethought be avoided. The Second Law states unequivocally that the…
Life as "Improbable Distribution of Molecules"
At the end of the last century Boltzman made an elegant redefinition of entropy as a measure of the probability of a molecular distribution. It may seem at first obscure, but it leads directly to what we seek. It implies that the probably life or one of its products, and if we find such a distribution to be global in…
Museums for Rebooting Civilization
"You don't see the point of a museum, Horst. It's for the next rise in the Cycles. Savages come to put together another civilization. The faster they can do it, the longer it'll be before another collapse because they'll be expanding their capabilities faster than the population. See? So the savages get their choice…
Kennedy's Speech to Congress Requesting Funds for the Space Program
First, I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth. No single space project in this period will be more impressive to mankind, or more important for the long-range exploration of space; and none…
How to Disguise a Helium Atom as a Hydrogen Atom
Donald Fleming of the University of British Columbia in Vancouver, Canada, and colleagues managed to disguise a helium atom as a hydrogen atom byreplacing one of its orbiting electrons with a muon, which is far heavier than an electron. Because it is so heavy, the muon sits 200 times closer to the helium nucleus than…
Computer Programming Brings Complex Thought to the Masses
Omni: Does that limit the number of people who can contribute, or even understand what's being done? Feynman: Or else somebody will develop a way of thinking about the problems so that we can understand them more easily. Maybe they'll just teach it earlier and earlier. You know, it's not true that what is called…
A Chess Metaphor for Understanding Physics Through Science
One way, that's kind of a fun analogy in trying to get some idea of what we're doing in trying to understand nature, is to imagine that the gods are playing some great game like chess, let's say, and you don't know the rules of the game, but you're allowed to look at the board, at least from time to time, in a little…
Physics Work is Like Building a House of Cards
To do high, real good physics work you do need absolutely solid lengths of time, so that when you're putting ideas together which are vague and hard to remember, it's very much like building a house of cards and each of the cards is shaky, and if you forget one of them the whole thing collapses again. You don't know…
The Chance of Error in Atomic Sized Computers
The first thing that you would worry about when things get very small is Brownian motion--everything is shaking about and nothing stays in place. How can you control the circuits then? Furthermore, if a circuit does work, doesn't it now have a chance of accidentally jumping back? If we use two volts for the energy of…
The Net is a Playground of Entropy
It may be fun to surf the Net and follow things randomly, but there's value in structure. The Net is a playground of entropy--the structurelessness that occurs when energy dissipates from a system. Yes, the Net also fosters self-organization, when individuals apply their energy, selectng and filtering information for…
Evolution as Entropy Versus Organization
'Evolution doesn't view earth's history as a conflict between good and evil. It does essentially view it as a conflict between life and death, between increased organization and more efficient energy use on the part of life, and an opposing tendency of nonliving matter to become disorganized and lose energy--entropy…
An Empirical Research Model for Software Development
2cThe research approach is strongly empirical. At the workplace of each member of the subject group we aim to provide nearly full-time availability of a CRT work station, and then to work continuously to improve both the service available at the stations and the aggregate value derived therefrom by the group over the…
