Famous quotes containing the words signal, recognition and/or particle:

    Perhaps having built a barricade when you’re sixteen provides you with a sort of safety rail. If you’ve once taken part in building one, even inadvertently, doesn’t its usually latent image reappear like a warning signal whenever you’re tempted to join the police, or support any manifestation of Law and Order?
    Jean Genet (1910–1986)

    The person who designed a robot that could act and think as well as your four-year-old would deserve a Nobel Prize. But there is no public recognition for bringing up several truly human beings.
    C. John Sommerville (20th century)

    Experience is never limited, and it is never complete; it is an immense sensibility, a kind of huge spider-web of the finest silken threads suspended in the chamber of consciousness, and catching every air-borne particle in its tissue.
    Henry James (1843–1916)
