Renormalization

Renormalization is a process used in physics and mathematics to handle infinities that arise in calculations, especially in quantum field theory. When physicists try to predict outcomes, they often encounter infinite values that don’t make sense. Renormalization helps "tame" these infinities by redefining the parameters of the theory (like mass and charge) so that predictions match experimental results. Essentially, it’s a way of ensuring that our models remain useful and accurate, allowing us to make sense of the universe while avoiding mathematical inconsistencies.
