The terrifying physics of going up-mast in heavy seas are inescapable.

Physics is a terrible, terrible, terrible thing. It takes all of your energy, all of your time and all of your attention.

Tomorrow is going to be a big physics day.

One can only learn by teaching.

In geometric and physical applications, it always turns out that a quantity is characterized not only by its tensor order, but also by symmetry.

When the province of physical theory was extended to encompass microscopic phenomena through the creation of quantum mechanics, the concept of consciousness came to the fore again. It was not possible to formulate the laws of quantum mechanics in a fully consistent way without reference to the consciousness.

Quantum physics is one of the hardest things to understand intuitively, because essentially the whole point is that our classical picture is wrong,

Quantum physics fluctuates all the time. But now the fluctuations are not just particles coming into and out of existence, which happens all the time. It's whole universes coming into and out of existence.

Physics without mathematics is meaningless.

Physics has the cutest words.
