I'm on a crusade to get movie directors to get their science right because, more often than they believe, the science is more extraordinary than anything they can invent.

Based on the science, you can make somewhat clear statements: The number of people who can survive on six hours of sleep without impairment is zero.

No isolated experiment, however significant in itself, can suffice for the experimental demonstration of any natural phenomenon; for the "one chance in a million" will undoubtedly occur, with no less and no more than its appropriate frequency, however surprised we may be that it should occur to us.

[Concerning] the usual contempt with which an orthodox analytic group treats all outsiders and strangers ...

You can never develop a science that way, only an orthodox church.

But nearly all the grandest discoveries of science have been but the rewards of accurate measurement and patient long-continued labour in the minute sifting of numerical results.
