Effective Day

Famous quotes containing the words effective and/or day:

“As in political revolutions, so in paradigm choice—there is no standard higher than the assent of the relevant community. To discover how scientific revolutions are effected, we shall therefore have to examine not only the impact of nature and of logic, but also the techniques of persuasive argumentation effective within the quite special groups that constitute the community of scientists.”
—Thomas S. Kuhn (b. 1922)

“A day for toil, an hour for sport,
But for a friend is life too short.”
—Ralph Waldo Emerson (1803–1882)
