Science Generators

Conway’s Game of Life is perhaps best viewed not as a single shorthand abstraction but rather as a generator of such abstractions. We get a whole bunch of useful abstractions—or at least a recipe for how to generate them—all for the price of one. And this points us to one especially useful shorthand abstraction: the strategy of Looking for Generators. We confront many problems. We can try to solve them one by one. But alternatively, we can try to create a generator that produces solutio...

 Optical Illusions are "Brain Failures"

Human perception is rife with ways of getting things wrong. We don't like to admit it, because we have a high opinion of our biology, but it's true. Here's an example: We've all seen drawings that create optical illusions. They're lots of fun, but they should actually be called "brain failures." That's what's happening—a failure of human perception. Show us a few clever drawings, and our brains can't figure out what's going on. We're poor data-taking devices. That's why we have science; tha...

 The Loss of the "Four Elements"

The disappearance of the traditional world of the ‘four elements’ was revolutionary. It was as radical in the world of chemistry as Copernicus’s proof that the earth was not the centre of the solar system; or (some said) as Robespierre’s claim that the people, not the king, embodied sovereignty. Moreover, it was counter-intuitive: it went against common sense and common appearances. Surely water and air were primary, simple elements? Not at all: chemical experiment and scientific inst...
