An oscillation is a particular kind of motion in which an object repeats the same movement over and over. It is easy to see that a child on a swing and the pendulum on a grandfather clock both oscillate when they move back and forth along an arc. A...

The simplest coupled oscillator is a pair of linearly coupled harmonic oscillators, which is used as a model for a wide variety of physical systems—including the interactions of musical instruments and tuning forks, lattice vibrations, electrical...

Oscillatory activity is a pattern of rhythmic activity that can be generated within NEURAL NETWORKS either by intrinsic mechanisms within neurons, the direct interaction of adjacent neurons (see NEURON) or by the intervention of intermediate systems...

Just about any device that produces a back-and-forth or up-and-down motion—particularly if that motion is shaped like a sine wave--can be called an oscillator. One of the simplest examples is a pendulum; if the path of a pendulum were charted on...

Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. Familiar examples include a swinging pendulum and AC power. The term vibration is...

Using fire scars on nearly 5,000 tree stumps dating back 450 years, scientists have found that extended periods of major wildfires in the West occurred when the North Atlantic Ocean was going through periodic warming.With the North Atlantic at the start of a recurring warming...

Wild tigers, the oldest rain forest, the fastest train and the tallest building are just some of the 20 Asian wonders described in Conde Nast Traveler. Here is the complete list from the magazine's October issue, which is devoted to...

For nine seasons, the hit sitcom "Seinfeld" billed itself as a show about nothing. For stock-chart readers, some base patterns are about nothing too.These price consolidations have no recognizable pattern. They are corrections without the shapes or price action common among winning stocks.True, sometimes an...
