Tensor Quotes (3 quotes)
In geometric and physical applications, it always turns out that a quantity is characterized not only by its tensor order, but also by symmetry.
Maxwell's equationsâ€¦ originally consisted of eight equations. These equations are not â€śbeautiful.â€ť They do not possess much symmetry. In their original form, they are ugly. â€¦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 â€śbeauty.â€ť
Ultra-modern physicists [are tempted to believe] that Nature in all her infinite variety needs nothing but mathematical clothing [and are] strangely reluctant to contemplate Nature unclad. Clothing she must have. At the least she must wear a matrix, with here and there a tensor to hold the queer garment together.
