Critical Virtue
The critical virtue of the Daniels Escapement is the virtual elimination of the sliding friction component; i.e., the sliding of the pallet stones over the teeth of the escape wheel. What little sliding friction remains is due to the impossibility of maintaining an exact tangential geometry throughout the duration of an impulse.

Famous quotes containing the words critical and/or virtue:
“I know that I will always be expected to have extra insight into black texts—especially texts by black women. A working-class Jewish woman from Brooklyn could become an expert on Shakespeare or Baudelaire, my students seemed to believe, if she mastered the language, the texts, and the critical literature. But they would not grant that a middle-class white man could ever be a trusted authority on Toni Morrison.”
—Claire Oberon Garcia, African American scholar and educator. Chronicle of Higher Education, p. B2 (July 27, 1994)
“See where she comes, apparelled like the spring.
Graces her subjects, and her thoughts the king
Of every virtue gives renown to men.”
—William Shakespeare (1564–1616)
