"How did Biot arrive at the partial differential equation? [the heat conduction equation] . . . Perhaps Laplace gave Biot the equation and left him to sink or swim for a few years in trying to derive it. That would have been merely an instance of the way great mathematicians since the very beginnings of mathematical research have effortlessly maintained their superiority over ordinary mortals." »Clifford Truesdell

"equation (1.2-9) is a second order, nonlinear, vector, differential equation which has defied solution in its present form. It is here therefore we depart from the realities of nature to make some simplifying assumptions..." »Bate, Mueller & White, 1971, "Fundamentals of Astrodynamics"

"In its famous paradox, the equation of money and excrement, psychoanalysis becomes the first science to state what common sense and the poets have long known -- that the essence of money is in its absolute worthlessness." »Norman O. Brown

"Time is just something that we assign. You know, past, present, it's just all arbitrary. Most Native Americans, they don't think of time as linear in time, out of time, I never have enough time, circular time, the Stevens wheel. All moments are happening all the time." »Robin Green

"Yes, we have to divide up our time like that, between our politics and our equations. But to me our equations are far more important, for politics are only a matter of present concern. A mathematical equation stands forever." »Albert Einstein

"For a smart material to be able to send out a more complex signal it needs to be nonlinear. If you hit a tuning fork twice as hard it will ring twice as loud but still at the same frequency. That's a linear response. If you hit a person twice as hard they're unlikely just to shout twice as loud. That property lets you learn more about the person than the tuning fork." »Neil Gershenfeld
