Re: [math-fun] discrete version of exp(d/dz)

Quoting Eugene Salamin <gene_salamin@yahoo.com>:

Can you explain the "strike at the roots of quantum mechanics"?

As Dirac noted, that commutation relation distinguished classical hamiltonian mechanics from the new quantum mechanics; he saw it as the harbinger of a whole new kind of science (oops! Ive quoted the wrong authority), with q-numbers and c-numbers. That was his reaction to Heisenberg's preprint (or rather, galley proofs). -hvm ------------------------------------------------- www.correo.unam.mx UNAMonos Comunicándonos
