All integral laws of spectral lines and of atomic theory spring originally from the quantum theory. It is the mysterious organon on which Nature plays her music of the spectra, and according to the rhythm...

There are many, many, many worlds branching out at each moment you become aware of your environment and then make a choice.

The more we delve into quantum mechanics the stranger the world becomes; appreciating this strangeness of the world, whilst still operating in that which you now consider reality, will be the foundation for shifting the...

All perception is the result of electrical impulses in the brain – the world of the individual is tantamount to a highly advanced computer running and analyzing programs in its working memory.

If the deep logic of what determines the value of the fine-structure constant also played a significant role in our understanding of all the physical processes in which the fine-structure constant enters, then we would...

Realizing its fundamental importance in understanding spectral lines, in atomic physics and in the theory of how light and electrons interact, quantum electrodynamics, Pauli and Heisenberg were determined to derive it from quantum theory rather...

I have tried to read philosophers of all ages and have found many illuminating ideas but no steady progress toward deeper knowledge and understanding. Science, however, gives me the feeling of steady progress: I am...

Let us begin with the fine-structure constant. … The fine-structure constant is really the ratio of two natural units or atoms of action. … We obtain action when we multiply energy by time. … We...

The Theory of Relativity confers an absolute meaning on a magnitude which in classical theory has only a relative significance: the velocity of light. The velocity of light is to the Theory of Relativity as...

Another very good test some readers may want to look up, which we do not have space to describe here, is the Casimir effect, where forces between metal plates in empty space are modified by...

It was like bouncing tennis balls off a mystery piece of furniture and deducing, from the direction in which the balls ricocheted, whether it was a chair or a table or a Welsh dresser.

Quantum theory tells us, Mr. Thomas, that every point in the universe is intimately connected to every other point, regardless of apparent distance. In some mysterious way, any point on a planet in a distant...

IF”—then you could create a time machine that apparently obeys Einstein’s equation and perhaps the laws of quantum theory.

One can still say that quantum mechanics is the key to understanding magnetism. When one enters the first room with this key there are unexpected rooms beyond, but it is always the master key that...

By far the most important consequence of the conceptual revolution brought about in physics by relativity and quantum theory lies not in such details as that meter sticks shorten when they move or that simultaneous...

You are deluded if you think that the world around you is a physical construct separate from your own mind.

Physical reality does not require that we be pleased with its mechanism.
