Differential Equation Quotes & Sayings

I'm really good with problems. I can solve a differential equation in my head. I chew through trig angles like candy. I know this, and it just makes it worse. Because I don't know how to solve this one. — Kekla Magoon

There's no doubt that scientific training helps many authors to write better science fiction. And yet, several of the very best were English majors who could not parse a differential equation to save their lives. — David Brin

In order to solve this differential equation you look at it till a solution occurs to you. — George Polya

By June 1949 people had begun to realize that it was not so easy to get a program right as had at one time appeared. I well remember when this realization first came on me with full force. The EDSAC was on the top floor of the building and the tape-punching and editing equipment one floor below on a gallery that ran round the room in which the differential analyzer was installed. I was trying to get working my first non-trivial program, which was one for the numerical integration of Airy's differential equation. It was on one of my journeys between the EDSAC room and the punching equipment that "hesitating at the angles of stairs" the realization came over me with full force that a good part of the remainder of my life was going to be spent in finding errors in my own programs. — Martin Campbell-Kelly

It is a curious historical fact that modern quantum mechanics began with two quite different mathematical formulations: the differential equation of Schroedinger and the matrix algebra of Heisenberg. The two apparently dissimilar approaches were proved to be mathematically equivalent. — Richard P. Feynman

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 A. Truesdell

Messages from the unseen that the great Alan Turing left behind at his death: Science is a differential equation. Religion is a boundary condition. — Jim Holt

We had been seen. The thought stayed with me as I disposed of the leftovers - how could it not? I drove with one eye on the rearview mirror, waiting for the blinding burst of blue light to flare at my bumper and the brief harsh whoop! of a siren. But nothing came; not even after I ditched Valentine's car, climbed into mine, and drove carefully home. Nothing. I was left entirely at liberty, all alone, pursued only by the demons of my imagination. It seemed impossible - someone had seen me at play, as plainly as it was possible to be seen. They had looked at the carefully carved pieces of Valentine, and the happy-weary carver standing above them, and it would not take a differential equation to arrive at a solution to this problem - A plus B equals a seat in Old Sparky for Dexter, and someone had fled with this conclusion in perfect comfort and safety - but they had not called the police? It — Jeff Lindsay

The integrals which we have obtained are not only general expressions which satisfy the differential equation, they represent in the most distinct manner the natural effect which is the object of the phenomenon ... when this condition is fulfilled, the integral is, properly speaking, the equation of the phenomenon; it expresses clearly the character and progress of it, in the same manner as the finite equation of a line or curved surface makes known all the properties of those forms. — Joseph Fourier

It must be admitted that science has its castes. The man whose chief apparatus is the differential equation looks down upon one who uses a galvanometer, and he in turn upon those who putter about with sticky and smelly things in test tubes. — Gilbert Newton Lewis
