Radius of the electron and uncertainty

  • #1

Main Question or Discussion Point

i thought that electrons are merely abstract thing or statistical entities, so i mitigated every attempt to visualize them as something that has a shape like a sphere, has a radius, internal structure,
i thought that any attempt to measure a radius (if any) could result in uncertainty in measuring so we will never know actual radius
until i found a lecturer talking about that there is a radius and electron can be visualized as small ball!!!
What is wrong in my understanding?

Yes, it can be a very small ball. Smaller than the classical electron now in fact.


And yes, Lloyd Motz has suggested that the radius and mass of a particle are effected by the uncertainty principle.

How come we can talk about shape!!?, without talk about internal structure
i find difficulties in accepting this idea
i think we must migrate the idea of shape when talking about elementary particles wich are almost point-like

And yes, Lloyd Motz has suggested that the radius and mass of a particle are effected by the uncertainty principle.
this is a support to my idea that we can't talk about anything like shape, volume, density, since all of these values that subject to the uncertainty principle

IWantToLearn, You are correct. An elementary particle like an electron is NOT a small ball. It's pointlike, which means its size (if it even has one) is too small to be observed.
