As I was working I noticed that the way I designed the differential gearing actually created a spare drive that sat directly below the emperor's feet, or where they would be if he were to sit in the chariot.
Newton, of course, was the inventor of differential calculus so his place in the tale is quite special.
What you need to learn how to do is analyze situations and do differential diagnoses and understand the principle and the concepts rather than learn all the details, and medical school doesn't begin to do that.
Love can reach the same level of talent, and even genius, as the discovery of differential calculus.
We have the only cookbook in the world that has partial differential equations in it.
At the end of the day, the differential, I believe, on the airline space has got to be about the product and the service that you provide. And again, I can't express that enough. That comes from people. It is a people business, and my primary focus is to get our 84,000-plus people back aligned, back engaged, and back focused on our customer.
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.
The standard high school curriculum traditionally has been focused towards physics and engineering. So calculus, differential equations, and linear algebra have always been the most emphasized, and for good reason - these are very important.
I thought of computers as very low class. I thought of myself as a pure mathematician and was interested in partial differential equations and topology and things like that.
