[edit] relationship between amplitude and density

Can someone explain what is the relationship between probability amplitude and probability density function? Ohanian 00:22, 31 October 2005 (UTC)

[edit] proof

any chance of a proof of the probability conservation law?

[edit] Wavefunction is a probability amplitude

This entry is superfluous in that the terms "wavefunction" and "probability amplitude" are synonymous. Also, the quantum continuity equation and the concept of probability current (probability flux) deserve an entry of their own. Does anyone object to dissolving this entry and creating a new one dealing exclusively with probability current in quantum mechanics? --Adfgvx 01:36, 28 December 2005 (UTC)

Update: I've created a probability current entry which is much more extensive than the treatment here. --Adfgvx 06:38, 28 December 2005 (UTC)

Is this article about the same thing as a wavefunction ? Becuase if it is, they should be merged. Fresheneesz 06:58, 1 May 2006 (UTC)
It is also possible to have discrete probability amplitudes, such as in describing spin, so I would not suggest merging the articles. --Qrystal (talk) 21:10, 2 January 2008 (UTC)

[edit] Complex numbers?

Could you put an explanation of what complex numbers have to do with probability? I'm confused.

Complex numbers don't arise because of probability, the arise because of the probability distribution. Waves are often described by sines and cosines - functions that are inherintly tied to complex numbers. The description of the wavefunction is thus often a complex function - and the wavefunction is related to the probability. Fresheneesz 06:58, 1 May 2006 (UTC)
