Physicists from the Canadian Institute for Measurement Standards are the first to measure a quantum mechanical wave function. And it only took 88 years from the formulation of Schroedinger’s equation!

Students calculate wavelength, frequency, or the velocity of a wave. Atomic Theory: Electrons on the Atom Bohr’s model of the atom are described. Students calculate wavelength, frequency, or the ...

1926: Nuclear physicist Erwin Schrödinger writes a letter to Albert Einstein, introducing a new term: wave mechanics. Things are getting particularly interesting. If they are things. Well, probably.

If P(nl; r) is the (nl) radial wave function in an atom of atomic number N, and PH(nl; r) is the corresponding wave function of hydrogen, then, for a given configuration and for large N N-1/2P(nl; r) ...

For surfers, it's not enough just to wait for the right wave: they still have to know how to catch it. As it turns out, one challenge faced by surfers also applies to protons. An experiment recently ...

Clocks in space: narrowband gravitational-wave detector could take off. (Courtesy: iStockphoto/hh5800) A proposal for a gravitational-wave detector made of two space-based atomic clocks has been ...
