The length scale problem: how to make a tiny wave model of a particle?

›
Our previous, extensive, post brought up the old problem about the wave-particle duality. When should we model particles as particles and wh...

Pair production in a collision: a wave-particle model

›
In the latest two blog posts we showed that a classical electromagnetic field might be adequate for explaining Coulomb scattering, as well a...
