Tensor Quotes

I was appalled to find that the mathematical notation on which I had been raised failed to fill the needs of the courses I was assigned, and I began work on extensions to notation that might serve. In particular, I adopted the matrix algebra used in my thesis work, the systematic use of matrices and higher-dimensional arrays (almost) learned in a course in Tensor Analysis rashly taken in my third year at Queen's, and (eventually) the notion of Operators in the sense introduced by Heaviside in his treatment of Maxwell's equations. (Kenneth E. Iverson)

(...) the bottom line is that if you believe in an external reality independent of humans, then you must also believe that our physical reality is a mathematical structure. Nothing else has a baggage-free description. In other words, we all live in a gigantic mathematical object-one that's more elaborate than a dodecahedron, and probably also more complex than objects with intimidating names such as Calabi-Yau manifolds, tensor bundles and Hilbert spaces, which appear in today's most advanced physics theories. Everything in our world is purely mathematical-including you.

Max Tegmark

Before the spirit could seek into it, the mind must. She studied the tensor equations as once she studied the sutras, she meditated upon the koans of science, and at last she began to feel her oneness with all that was, and in the vision find peace.

Poul Anderson

Eight, sir; seven, sir; Six, sir; five, sir; Four, sir; Three, sir; Two, sir; one! Tenser, said the Tensor. Tenser, said the Tensor. Tension, apprehension, And dissension have begun.

Alfred Bester

Maxwell's equations... originally consisted of eight equations. These equations are not "beautiful." They do not possess much symmetry. In their original form, they are ugly.... However, when rewritten using time as the fourth dimension, this rather awkward set of eight equations collapses into a single tensor equation. This is what a physicist calls "beauty," because both criteria are now satisfied.
