  • In theoretical physics, renormalization is essential to remove infinities from equations.

Examples

  • The point of renormalization was to get rid of bare energies and replace them with observed energies.

    Academic text (2005)
  • Then Wilson's work on the renormalization group brought home to both communities the importance of mutual education.

    Academic text (1993)
  • We could go through the renormalization and find these results.

  • As each decision is processed, the index is changed any time a renormalization is required.

    Academic text (1998)
  • It's just a renormalization of the units, that's all.

  • Processing does not continue until all additional renormalizations have completed.

    Academic text (1998)
  • Therefore, in this modified theory, there is no infinite renormalization of the Newton constant.

    Academic text (2018)
  • Actually, for a finite quantum field theory of gravity, no renormalization of the Newton constant is needed.

    Academic text (2018)
  • Of course, the observable consequences of the theory cannot depend on that arbitrary renormalization scale.

    Academic text (2004)
  • Maintaining the interval calculation within the order of unity requires renormalization of the code string and interval size.

Morphology

renormalization = renormalize (semi-transparent) = re + normal + ize + ation

This is a standard noun formation from the verb 'renormalize' meaning the process or result of that action.

Etymology

The word renormalization starts with re- meaning 'again' and the part normal meaning 'usual' or 'rule'. Think of it like re-setting a scale or re-calibrating a machine so numbers fit the correct rule, which is why in science it means adjusting values to remove errors or impossibly large results.
