Tunneling, also known as the tunnel effect, is a quantum mechanical phenomenon by which a tiny particle can penetrate a barrier that it could not, by any classical or obvious means, pass. Though seemingly miraculous, the effect does have some intuitive...

During the 1920s, the French physicist Louis de Broglie introduced the notion that particles can have wave properties. The equations that he, Erwin Schrödinger, and other physicists developed to describe these properties led to some startling new...

In quantum mechanics, quantum tunneling is a micro and nanoscopic phenomenon in which a particle violates the principles of classical mechanics by penetrating or passing through a potential barrier or impedance higher than the kinetic energy of the...

Quantum mechanics challenges classical views, and leaves questions in its wake In the early years of the 20th century, a new theory, quantum mechanics, revolutionized physicists' understanding of nature. But delving into the subatomic realm meant rethinking some fundamental assumptions: Here, information passes...

Anyone for tennis? A catalyst uses quantum mechanics to speed chemical reactions IMAGINE hitting a tennis ball against a wall. Time after time, the ball bounces back. But, just occasionally, the ball disappears only to reappear on the other side of...
