Algorithms are Subjective/Creative Things

he algorithm may be the essence of computer science – but it’s not precisely a scientific concept. An algorithm is a system, like plumbing or a military chain of command. It takes knowhow, calculation and creativity to make a system work properly. But some systems, like some armies, are much more reliable than others. A system is a human artefact, not a mathematical truism. The origins of the algorithm are unmistakably human, but human fallibility isn’t a quality that we associate with ...

 Flexible Thinkers

Flexible thinkers are able to shift through multiple perceptual positions at will. One perceptual orientation is what Jean Piaget called egocentrism, or perceiving from our own point of view. By contrast, allocentrism is the position in which we perceive through another person's orientation. We operate from this second position when we empathize with another's feelings, predict how others are thinking, and anticipate potential misunderstandings. Another perceptual position is macrocentric....

 The Difference Between Average and Great Chessmasters

Great players like Kasparov do not delude themselves into thinking they can calculate all these possibilities. This is what separates elite players from amateurs. In his famous study of chess players, the Dutch psychologist Adriaan de Groot found that amateur players, when presented with a chess problem, often frustrated themselves by looking for the perfect move, rendering themselves incapable of making any move at all. Chess masters, by contrast, are looking for a good move—and certainly...

 The Monty Hall Problem

Here’s how Monty’s deal works, in the math problem, anyway. (On the real show it was a bit messier.) He shows you three closed doors, with a car behind one and a goat behind each of the others. If you open the one with the car, you win it. You start by picking a door, but before it’s opened Monty will always open another door to reveal a goat. Then he’ll let you open either remaining door. Suppose you start by picking Door 1, and Monty opens Door 3 to reveal a goat. Now what should y...

 Art and Science Require Both Creativity and Rationality

How often people speak of art and science as though they were two entirely different things, with no interconnection. An artist is emotional, they think, and uses only his intuition; he sees all at once and has no need of reason. A scientist is cold, they think, and uses only his reason; he argues carefully step by step, and needs no imagination. That is all wrong. The true artist is quite rational as well as imaginative and knows what he is doing; if he does not, his art suffers. The true sc...

 Wikipedia's Rules of Etiquette

Assume good faith. Treat others as you would have them treat you--even if they are new. We were all new once. ...raw text may be ambiguous and often seems ruder than the same words coming from a person standing in front of you...Be careful of how you interpret what you read: what you understand might not be what the writer means. Work towards agreement. Argue facts, not personalities. Do not ignore questions. Concede a point when you have no response to it, or admit when you disagree based o...
