Bohr`s quantum postulate and time in quantum mechanics
... In his later writings the importance Bohr gave to this consequence of the quantum postulate became even clearer. In successive drafts for an article published in 1956, Bohr uses the word ‘wholeness’, ‘indivisibility’, and ‘unity’ (Honner, 1987, p. 69), finally writing “The essential indivisibility o ...

The same annulus with an added dot is the multiplication by X endomorphism of A. Figure 12 shows two other examples. ...
