(British renormalisation)
noun riːˌnɔːm(ə)lʌɪˈzeɪʃ(ə)nˌrēˌnôrməliˈzāSHən
mass nounPhysics
  • A method used in quantum mechanics in which unwanted infinities are removed from the solutions of equations by redefining parameters such as the mass and charge of subatomic particles.

    Example sentencesExamples
