Kinetic Energy: T or K in Mechanics/QM?

Click For Summary

Discussion Overview

The discussion revolves around the notation used for kinetic energy in classical mechanics and quantum mechanics, specifically questioning why kinetic energy is denoted as T in classical mechanics and whether K is also a valid notation in quantum mechanics.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant notes that in classical mechanics, kinetic energy is denoted as T and questions why K is not used.
  • Another participant mentions that in quantum mechanics, the kinetic energy operator is sometimes denoted by T, but has also been seen as K.
  • Several posts introduce a mysterious tone, suggesting a deeper, perhaps esoteric significance to the notation that remains unexplained.

Areas of Agreement / Disagreement

Participants express differing views on the notation for kinetic energy, with no consensus reached on the reasons behind the use of T versus K.

Contextual Notes

The discussion includes references to historical or mythical elements regarding the notation, which may imply limitations in understanding the origins or conventions of the terms used.

In classical mechanics, the kinetic energy is denoted T. Why not K? In QM the kinetic energy operator is sometimes denoted by T as well although I have seen it denoted as K.
