gre Posted January 2, 2009 Share Posted January 2, 2009 Are electrons considered to be 2 dimensional within a single frame (i.e. their time was frozen) .. Also can an object in 2 spatial dimensions have mass? Thanks. Link to comment Share on other sites More sharing options...
ydoaPs Posted January 2, 2009 Share Posted January 2, 2009 IIRC, electrons are zero-dimensional. Link to comment Share on other sites More sharing options...
Mr Skeptic Posted January 2, 2009 Share Posted January 2, 2009 No one considers electrons to be two dimensional as far as I know. They are sometimes considered points, spheres, or fuzzy probability distributions depending on what theory you are modeling them in. Link to comment Share on other sites More sharing options...
timo Posted January 2, 2009 Share Posted January 2, 2009 Are electrons considered to be 2 dimensional No. within a single frame ??? (i.e. their time was frozen) No. Also can an object in 2 spatial dimensions have mass? Sure. But what you asked for is not what you wanted to ask. What you probably wanted to know is something like "only massless particles can travel at c and only massless particles experience zero time between two different events".

gre Posted January 2, 2009 Author Share Posted January 2, 2009 In a nutshell, I was just wondering how point particles such as electrons get their 3 dimensions in space, and if their "spin" had anything to do with it. What would an electron look like without spin? Link to comment Share on other sites More sharing options...

What would an electron look like without spin? An electron without spin would look like it doesn't have a tiny magnet embedded in it. Link to comment Share on other sites More sharing options...

Klaynos Posted January 3, 2009 Share Posted January 3, 2009 It's more complicated than that. An electron with 0 spin would be a completely different particle, and we'd have to apply different statistics to it (bose-einstein instead of fermion). There's no way you can just say "no spin, so this will happen" it would be fundamentally different. I've never heard of the electron being considered 2D? It can be confined to 2D that is true (or even 0D). They are 3D because they can move in 3 dimensions and the forces they exert are spherically symmetric (and therefore act in 3 dimensions).
