Untitled[edit]

I think that this should not be a simple redirect, as "superposition" has more meanings than the quantum one. For example, in archaeology and geology there is the "Law of Superposition", which states that the lowest stratum in a stratigraphic stack is the oldest (yes, I know this is common sense, but it's the basis of most geology). And yes, I'd be willing the write the article on this law. Stormwriter — Preceding signed comment added by Stormwriter (talk • contribs) 15:31, 15 November 2002 (UTC)[reply]

And so you did; excellent job. 68.123.231.110 19:28, 17 July 2006 (UTC)[reply]

Multiple realities or universes!?[edit]

Surely this is not the most obvious way to disambiguate the topic; most people will encounter superposition as simply the 'overlapping' of two waves. Roberdin 22:12, 5 November 2006 (UTC)[reply]

I agree[edit]

Move the pan-dimensional string theory talk to its own page and make this one just a pure disambiguation page. —The preceding unsigned comment was added by 213.100.20.9 (talk) 13:12, 28 March 2007 (UTC).[reply]

Not having anything to do with waves!![edit]

Not having anything to do with waves!!
The Principle of Superposition is FAR MORE general than those things having to do with waves. Most kinds of superposition in physical systems that are linear do not have anything to do with waves.
For example, in free space, superposition applies for gravitational fields, for electrostatic potentials, for magnetostatic potentials, and indeed for all kinds of electromagnetic fields whatsoever.
In linear circuits in electricity, superposition applies to DC circuits, to AC circuits, and to any kind of linear circuit whatever.
In incompressible and nonviscous gases and fluids (in fluid mechanics), superposition holds. In a simple example, there is Dalton's Law of Partial Pressures. An example of this is that in our atmosphere. Let's let Pn be the pressure of the nitrogen, Po be the pressure of the oxygen, Pa be the pressure of the argon, and Pe be the pressure of everything else (water vapor, carbon dioxide, methane, etc.).
Then P(measured) = Pn + Po + Pa + Pe .
This is purely superposition of the pressures.47.215.180.7 (talk) 11:13, 24 December 2017 (UTC)[reply]

True. However, I have trimmed back your edits slightly as this is a disambiguation page. --catslash (talk) 17:59, 24 December 2017 (UTC)[reply]
