What is "constants"

Usage examples of "constants".

Roughly speaking, the string coupling constants play a role analogous to temperature in our desert analogy.

But as we vary their respective coupling constants, the theories transmute among themselves.

If the respective coupling constants are small, our best current answers to these questions are described in previous chapters, since at small coupling constants we are led back to the theory of strings.

But if the coupling constants are not small, no one currently knows the answers.

By varying coupling constants and curled-up Calabi-Yau geometry, we see that all string constructions are, once again, different phases of a single theory.
