Idea behind renormalization in physics

The problem of infinities first arose in the
classical electrodynamics of point particles in the 19th
and early 20th century.

The mass of a charged particle should include the
mass–energy in its electrostatic field (electromagnetic
mass). The total effective mass of a (spherical)
charged particle includes the actual bare mass in
addition to the electromagnetic one. If the bare mass is
allowed to be negative, it might be possible to take a
consistent point limit. This was called renormalization,
and Lorentz and Abraham attempted to develop a
classical theory of the electron this way.

This early work was the inspiration for later attempts at
regularization and renormalization in quantum field
theory.

Very nice video i dont process those things on your level yet but i must say i grasped some of the things u mentioned here.
Thank you

I was thinking maybe they took fiber bundles and worked the ending cycles off and renormalized to a block phi cycle. You never know how different logics throw numbers around until you know
