Dichotomies

Usage examples of dualities.

Various physicists worked on each, but without an understanding of the dualities they appeared to be different theories.

As we discussed in Chapter 12, the dualities underlying the unity of the five string theories show us that physical processes that occur in any one string formulation can be reinterpreted in the dual language of any of the others.

I think many share the view that the recently uncovered dualities point toward a new, more geometrical framework for quantum mechanics, in which space, time, and quantum properties will be inseparably joined together.

The dualities are ever-present on earth: disease and health, pain and pleasure, loss and gain.
