Paul Dirac on discovering the Poisson bracket–commutator link
Original: Paul Dirac recounting how he found the link between the Poisson bracket and the commutator: https:// youtu.be/2GwctBldBv
A recorded interview clip of physicist Paul Dirac is being shared, in which he recounts how he realised that the classical Poisson bracket in mechanics corresponds to the quantum commutator, a key step in the formulation of quantum mechanics. The clip is circulating among mathematicians and physicists, with readers pointing to recent arXiv work on related history.
Why now: The historical anecdote from one of quantum mechanics' founders is being recirculated after being referenced in a recent arXiv paper.
