The secret to succeeding with computers is to lutz with them. BART EISENBERG: Push buttons, move text, insert lines, hit control characters, add dot commands, bring up menus, invoke commands and invoke more of them. Try it backwards, try it sideways, try it upside down. The method, lf you can call it that, is vaguely scientific-in that you perform some action and observe the results. A playful attitude will get you further with these machines than weeks of serious endeavor.

 Computer Simulations Allow for Mistakes

. . in real life mistakes are likely to be irrevocable. Computer simulation, however, makes it economically practical to make mistakes on purpose. If you are astute, therefore, you can leam much more than they cost. Further¬ more, if you are at all discreet, no one but you need ever know you made a mistake.

 Knowledge Requires Interaction with the Material World

Where do correct ideas come from? Do they drop from the skies? No. Are they innate in the mind? No. They come from social practice, and from it alone; they come from three kinds of social practice, the struggle for production, the class struggle and scientific experiment. Where Do Correct Ideas Come from? (May 1963), 1st pocket ed., p. 1. It is man's social being that determines his thinking. Once the correct ideas characteristic of the advanced class are grasped by the masses, these ideas...

 We All Experiment

Experimentation is something done by everyone all the time. Babies experiment with what might be good to put in their mouths. Toddlers experiment with various behaviors to see what they can get away with. Teenagers experiment with sex, drugs, and rock and roll. But because people don’t really see these things as experiments or as ways of collecting evidence in support or refutation of hypotheses, they don’t learn to think about experimentation as something they do constantly and thus need...

 The Experiment that Disproved Astrology

A story told by this friend, Firminus, shook the young Augustine from his pagan faith. Firminus’ father, an earnest experimenter in astrology, always noted the positions of the stars and even “took care with the most exact diligence to know the birth of his very puppies.” Firminus’ father learned that one of his women-servants was to be delivered of a child at about the same time that Firminus’ mother was expecting. “Both were delivered at the same instant; so that both were const...

 How Intuition Messed Up the Laws of Motion

A most fundamental problem, for thousands of years wholly obscured by its complications, is that of motion. All those motions we observe in nature that of a stone thrown into the air, a ship sailing the sea, a cart pushed along the street are in reality very intricate. To understand these phenomena it is wise to begin with the simplest possible cases, and proceed gradually to the more complicated ones. Consider a body at rest, where there is no motion at all. To change the position o...

 The Rules of Magic Don't Make Any Sense

Some children would have waited until after their first trip to Diagon Alley. "Bag of element 79," Harry said, and withdrew his hand, empty, from the mokeskin pouch. Most children would have at least waited to get their wands first. "Bag of okane," said Harry. The heavy bag of gold popped up into his hand. Harry withdrew the bag, then plunged it again into the mokeskin pouch. He took out his hand, put it back in, and said, "Bag of tokens of economic exchange." That time his hand came ou...

 Observing a Slot Machine

[The] weakness of biological balance studies has aptly been illustrated by comparison with the working of a slot machine. A penny brings forth one package of chewing gum; two pennies bring forth two. Interpreted according to the reasoning of balance physiology, the first observation is an indication of the conversion of copper into gum; the second constitutes proof.

 Physics VS Metaphysics

In the 1920s, there was a dinner at which the physicist Robert W. Wood was asked to respond to a toast ... "To physics and metaphysics." Now by metaphysics was meant something like philosophy—truths that you could get to just by thinking about them. Wood took a second, glanced about him, and answered along these lines: The physicist has an idea, he said. The more he thinks it through, the more sense it makes to him. He goes to the scientific literature, and the more he reads, the more promi...

 Experiment Demonstrating Plants Produce Breathable Air

When air has been freshly and strongly tainted with putrefaction, so as to smell through the water, sprigs of mint have presently died, upon being put into it, their leaves turning black; but if they do not die presently, they thrive in a most surprizing manner. In no other circumstances have I ever seen vegetation so vigorous as in this kind of air, which is immediately fatal to animal life. Though these plants have been crouded in jars filled with this air, every leaf has been full of life;...
