Total bullshit. The wave function is time dependent.
- tgb 13y agoThere are multiple ways of writing any equation: http://en.wikipedia.org/wiki/Time-independent_Schr%C3%B6dinger_equation#Time_independent_equation http://en.wikipedia.org/wiki/Time-independent_Schr%C3%B6ding...
- has2k1 13y agoGiven psi(x, t), if the relation between x and t is not non- linear. Then you can have a time-independent Schrodinger equation with a time-independent wave-function i.e psi(x). However, you do not need start with a time dependent wave function to justify the time-independent wave function.
