The Game of Black-and-White

WHEN WE were taught 1, 2, 3 and A, B, C, few of us were ever told about the Game of Black-and-White. It is quite as simple, but belongs to the hushed-up side of things. Consider, first, that all your five senses are differing forms of one basic sense—something like touch. Seeing is highly sensitive touching. The eyes…

Notes From the Cosmic Perspective

Culture is the things you do that you don’t notice. In Italy they have a pasta aisle. In America we have ready made cereal isle, Soft drink aisle. Culture of discovery doesn't last forever Backup mic display Bad seats people Periodic table flags Top countries of element discovery, noble gases Scientists on currency…

Collaborative Fractal Fictional History Building

In Microscope, you build an epic history as you play. Want to play a game that spans the entire Dune series, the Silmarillion, or the rise and fall of Rome in an afternoon? That’s Microscope. But you don’t play the history from start to finish, marching along in chronological order. Instead, you build your history…

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…

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…

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…

Lenses Supplement the Infirmities of the Senses

The next care to be taken, in respect of the Senses, is a supplying of their infirmities with Instruments, and, as it were, the adding of artificial Organs to the natural; this in one of them has been of late years accomplisht with prodigious benefit to all sorts of useful knowledge, by the invention of Optical…

Metaphor for the Uncertainty Principle

There is a slightly flawed yet very satisfying physical argument that gives some heuristic understanding of the uncertainty principle. Quantum mechanics endows all particles with a wavelike behavior, and waves have one striking property: they are disturbed only when they encounter objects larger than their wavelength…

Newton's Experiment Proving White Contains All Colors

Newton wasn't the first person to make a rainbow with a prism. Other people had already got the same result. But many of them thought the prism somehow 'coloured' the white light, like adding a dye. Newton's idea was quite different. He thought that white light was a mixture of all the colours, and the prism was just…

We Have Announced Our Presence to the Stars

There are those who predict a dire catastrophe if we broadcast our presence to another star. The extraterrestrials will come and – eat us, or something equally unpleasant. (Actually, if we are especially tasty, they need only sample one of us, determine what sequence of our amino acids makes us appetizing, and then…
