    Graduate Why does the wave function have to collapse upon measurement?

    How does the Copenhagen interpretation motivate its claim that the wave function of a quantum system collapses when a property of the system is being measured? I mean, was there some problem they were trying to solve by introducing the notion of wave function collapse? What would happen if the...

    Graduate Are There Any Cases of Non-Constant Particle Mass in Solid State Theory?

    In that case it would be more like a quasi-electron, not a real electron, right? Because the electron itself still has a constant mass.

    Graduate Are There Any Cases of Non-Constant Particle Mass in Solid State Theory?

    In the book "The Physics of Semiconductors" by Marius Grundmann, there is a note on one of the pages, saying: I have never heard of a case where a particle would have a non-constant mass, is there any such case at all?

    Why Doesn't a Soap Film Burst When Held Vertically?

    What are those forces? I understand that there has to be some, but I don't know which. What other forces are there that could play a role here? Do you mean that the surface tension can be different in different parts of the film? In that case it could definitely be the reason the liquid isn't...

    Why Doesn't a Soap Film Burst When Held Vertically?

    Yes. But it is still takes a very long time before the soap film bursts. The logical thing would be that the liquid would travel to the bottom of the film with free fall speed, since there is seemingly no net force keeping the liquid up. This means that the soap film would burst immediately when...

    Why Doesn't a Soap Film Burst When Held Vertically?

    It is said that a soap film will find the surface with the minimum area. If the two interfaces between the soap and the air meet, the soap film can effectively reduce its area by bursting. You would think that if you simply hold a soap film up vertically, all the liquid would want to go to the...

    What creates foam on stormy oceans?

    No, I wasn't, but I will look them up! Thanks!

    What creates foam on stormy oceans?

    I also ound the paper Real time modelling of multispectral ocean scenes, which also covers the rendering of white caps and which references a couple of older articles. This paper uses the vertical downward acceleration to determine where the whitecaps is located, and dynamically calculates a...

    What creates foam on stormy oceans?

    That is not what I am looking for, sorry, although it was a nice explanation for wave breaking caused by shoaling. The whitecaps I'm talking about are the white parts of the surface on stormy oceans such as can be seen for example in this picture I'm not exactly sure what it is that...

    What creates foam on stormy oceans?

    I believe that the chemistry section may give me a lot of useful information about sea foam, but when it comes to whitecaps, I still need a mechanical model for breaking of the wave crests, which is when whitecaps are formed. I will take your suggestion though and study disperse systems to see...

    What creates foam on stormy oceans?

    Right, that's the connection. Do you mean I will find out how whitecaps are formed by studying disperse systems? Thanks.

    What creates foam on stormy oceans?

    How can I use that to simulate whitecaps? What is the connection between whitecaps and colloidal or dispersive systems?

    What creates foam on stormy oceans?

    Thanks for the answers. I found a few different research papers about this (I'm surprised there aren't more). First, I found the paper Realistic Animation of Fluid with Splash and Foam which (by judging from the pictures) seems to handle splash very well, but not oceanic whitecaps (also called...

    What creates foam on stormy oceans?

    Hi! I'm going to simulate stormy oceans and the foam that is created on wave crests, and need to know what process it is that creates the foam. So, more specifically, do you have any idea what the conditions are for foam to be created?

    MHB Way to calculate/approximate 2D Fourier transform?

    In order to get a small enough matrix so that it becomes possible to transform it, you either have to sacrifice the resolution or the range of the original function. Both of those options are bad and will make the transformed function deviate from the true value.
