Truly to realize the ambitions of a science of mind does not solely involve learning about such issues as how we know, perceive and solve problems; it involves finding out tow hat extent the world...

In the 1920s, there was a dinner at which the physicist Robert W. Wood was asked to respond to a toast … ‘To physics and metaphysics.’ Now by metaphysics was meant something like philosophy—truths that...

In fact, meta- and particle physicists have more in common than one might suppose: both tug, if in slightly different directions, at the knots which hold the cosmos together, both look beyond the immediate world...

What’s the matter? What’s the antimatter? Does it antimatter?

(On the energy radiated by the Sun)It’s four hundred million million million million watts. That is a million times the power consumption of the United States every year, radiated in one second, and we worked...

A relativist is an individual who doesn’t know the difference between an adjective and an adverb.

Einstein, twenty-six years old, only three years away from crude privation, still a patent examiner, published in the Annalen der Physik in 1905 five papers on entirely different subjects. Three of them were among the...

The earth in its rapid motion round the sun possesses a degree of living force so vast that, if turned into the equivalent of heat, its temperature would be rendered at least one thousand times...

how much does a thought weigh?

There is no problem more difficult to solve than that created by ourselves.

He (Comings) has in the past performed successful energy-converting experiments, creating a ringing resonance by injecting certain frequencies into piezo-electric crystals. When the crystal was in resonance with the plenum of space, the power output...

He needs “space” and “time,” as if this were physics and not a human relationship.

Let’s grant that the stars are scattered through space, hither and yon. But how hither, and how yon? To the unaided eye the brightest stars are more than a hundred times brighter than the dimmest....

It can even be thought that radium could become very dangerous in criminal hands, and here the question can be raised whether mankind benefits from knowing the secrets of Nature, whether it is ready to...

We walked up and down in the snow, I on skis and she on foot (she said and proved that she could get along just as fast that way), and gradually the idea took shape...

We have written the equations of water flow. From experiment, we find a set of concepts and approximations to use to discuss the solution–vortex streets, turbulent wakes, boundary layers. When we have similar equations in...

‎In modern physics, there is no such thing as “nothing.” Even in a perfect vacuum, pairs of virtual particles are constantly being created and destroyed. The existence of these particles is no mathematical fiction. Though...

We all love a good story. We all love a tantalizing mystery. We all love the underdog pressing onward against seemingly insurmountable odds. We all, in one form or another, are trying to make sense...

A hint of – dare I say? – animism has entered into the scientific worldview. The physical world is no longer either dead or passively obedient to the “laws.

Relationships are physics. Time transforms things- it has to, because the change from me to we means clearing away the fortifications you’r put up around your old personality. Living with Susannah made me feel as...

The Heart of Gold fled on silently through the night of space, now on conventional photon drive. Its crew of four were ill as ease knowing that they had been brought together not of their...

The most striking impression was that of an overwhelming bright light. I had seen under similar conditions the explosion of a large amount—100 tons—of normal explosives in the April test, and I was flabbergasted by...

Primary causes are unknown to us; but are subject to simple and constant laws, which may be discovered by observation, the study of them being the object of natural philosophy.Heat, like gravity, penetrates every substance...

As chemists, we must rename [our] scheme and insert the symbols Ba, La, Ce in place of Ra, Ac, Th. As nuclear chemists closely associated with physics, we cannot yet convince ourselves to make this...

Physics is the story of the universe, with everything or nothing.

The expression e=mc2 is the ultimate statement in bounce per ounce.

This is 911 dispatch, and the nature of your emergency… fire, ambulance, police or… physics?

The Hartle-Hawking derivation of the unconditional probability of the existence of a universe of our sort is inconsistent with classical theism. The unconditional probability is very high, near to 1. For purposes of simplification, we...

God abhors a naked singularity.

There is nothing new to be discovered in physics now. All that remains is more and more precise measurement.

Something deeply hidden had to be behind things.

Asked in 1919 whether it was true that only three people in the world understood the theory of general relativity, [Eddington] allegedly replied: ‘Who’s the third?

Black holes collect problems faster than they collect matter.

… for it is very probable, that the motion of gravity worketh weakly, both far from the earth, and also within the earth: the former because the appetite of union of dense bodies with the...

Anyone who can relax, clear their mind, and envision being different in some way—such as more successful, funny, healthy, wealthy, or wise—can quantum jump. To initiate a quantum jump requires keeping an open mind that...

The death of God left the angels in a strange position.

It was quite the most incredible event that has ever happened to me in my life. It was almost as incredible as if you fired a 15-inch shell at a piece of tissue paper and...

The standard model of particle physics describes forces and particles very well, but when you throw gravity into the equation, it all falls apart. You have to fudge the figures to make it work.

Physics is about two things: time and the opposite.

There are many people who say there’s a God somewhere up there but, God is nothing more than a formula. Just a part of some law of physics that we have yet to understand.

Since the beginning of physics, symmetry considerations have provided us with an extremely powerful and useful tool in our effort to understand nature. Gradually they have become the backbone of our theoretical formulation of physical...

Arnold Sommerfeld generalized Bohr’s model to include elliptical orbits in three dimensions. He treated the problem relativistically (using Einstein’s formula for the increase of mass with velocity), … According to historian Max Jammer, this success...

Privacy, in fact, was almost as desirable for physics as it was for sex.

The total number of people who understand relativistic time, even after eighty years since the advent of special relativity, is still much smaller than the number of people who believe in horoscopes.

When you hurt someone, it initiates a chemical reaction in that person’s body that changes his/her mental condition. That means you are disturbing the arrangement of subatomic particles like protons and neutrons. These particles are...

A mathematician is a magician who converts adjectives into nouns: continuous into continuum, infinite into infinity, infinitesimal into location, 0D into point, 1D into line, curved into geodesic…

At his “World of Physics” Web site, Eric W. Weisstein notes that the fine structure constant continues to fascinate numerologists, who have claimed that connections exist between alpha, the Cheops pyramid, and Stonehenge!

Credentials are like potential energy, the compliments of a name on paper, in documents, word of mouth, but faith is like kinetic energy, the motion and the force that which is witnessed. Hence in the...

How much does a beam of light weigh?

Why is it so difficult for us to think in relative terms? Well, for the good reason that human nature loves absoluteness, and erroneously considers it as a state of higher knowledge.
