Physicist Erwin Schrödinger develops “wave mechanics,” a way to describe the energies of electrons in atoms by viewing electrons as waves. Wave mechanics was ...

This computer-generated visualization shows the wavelike pattern of a “quantum handshake” between a hydrogen atom emitting energy and another atom receiving the energy. (J. Cramer and C. Mead via ...

IBM’s Scanning Tunneling Microscope, or STM for short, uses an atomically sharp needle that passes over the surface of an (electrically conductive) object – the distance between the tip and object ...

Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

Humans have problems with quantum mechanics. We have excellent intuition about the motion of a tennis ball tossed in the air, but what about an electron trapped in a box? The tendency is to use the ...

Wave or particle? Science continues to unravel one of humanity's greatest mysteries in this universe in rather useful ways.

Sung to the abbess’s lines in “Maria” from The Sound of Music: “How do you catch a wave like Maria? How do you grab a cloud and pin it down? Oh, how do you solve a particle like Maria? How do you hold ...

Perhaps no other area of physics has enjoyed as much attention from scientists and non-scientists as quantum mechanics. The fame of quantum mechanics theories stands in juxtaposition to the physical ...

IN a letter to NATURE (April 17, 1926, p. 555), J. C. Slater suggested an explanation of the ‘quarter quantum numbers’ used in describing the band spectra of homopolar diatomic molecules by assuming ...
