quantum tunneling

Physics; Nanotechnology

When electrons pass through a barrier, without overcoming it or breaking it down. See this illustration.

quantum well

Physics; Nanotechnology

A P-N-P junction in which the "N" layer is ~10 nm (where traditional physics leaves off and quantum effects take over) and an "electron trap" is created. "If one makes a ...

quantum wire

Physics; Nanotechnology

Another form of quantum dot, but unlike the single-dimension "dot," a quantum wire is confined only in two dimensions - that is it has "length," and allows the electrons to ...

quantumbrain

Physics; Nanotechnology

Think of your brain. Now, think of your brain performing at vastly superior levels. Nanobots will become an as-needed addition to your existing neurons, extending your mental ...

orbital tower

Physics; Nanotechnology

also known as a "space tether", "beanstalk" or "heavenly funicular". A cable in synchronous orbit, with one end anchored to the surface of the Earth, often with a small asteroid ...

paradigm shift

Physics; Nanotechnology

When one conceptual world-view is replaced by another, or, a change of patterns on a massive scale. When Copernicus showed how the Earth rotates around the Sun, and not vice ...

pervasive computing

Physics; Nanotechnology

When computers (and sensors and actuators) become virtually invisible, and are used in almost every aspect of human commerce, interaction, and life. It will allow you full control ...
