In Physics
For more details on this topic, see moduli (physics).The term moduli space is sometimes used in physics to refer specifically the moduli space of vacuum expectation values of a set of scalar fields, or to the moduli space of possible string backgrounds.
Moduli spaces also appear in physics in cohomological field theory, where one can use Feynman path integrals to compute the intersection numbers of various algebraic moduli spaces.

Famous quotes containing the word physics:
“He who is conversant with the supernal powers will not worship these inferior deities of the wind, waves, tide, and sunshine. But we would not disparage the importance of such calculations as we have described. They are truths in physics because they are true in ethics.”
—Henry David Thoreau (1817–1862)
“The fundamental laws of physics do not describe true facts about reality. Rendered as descriptions of facts, they are false; amended to be true, they lose their explanatory force.”
—Nancy Cartwright (b. 1945)
