Quotes About Relativity

Between the conception of the idea of this special relativity theory and the completion of the corresponding publication, there elapsed five or six weeks. But it would be hardly correct to consider this as a birth date, because earlier the arguments and building blocks were being prepared over a period of years, although without bringing about the fundamental decision.

all our knowledge, both of time and space, is essentially relative....Position we must evidently acknowledge to be relative, for we cannot describe the position of a body in any terms which do not express relation....There are no landmarks in space; one portion of space is exactly like every other portion....We are, as it were, on an unruffled sea.

but his delightful essay "The Relativity of Wrong" is an exception. It is printed in one of the many collections of Asimov's essays, The Relativity of Wrong (New York: Kensington Books, 1988). Asimov makes the simple point—one that seems to

Nothing in the universe can travel at the speed of light, they say, forgetful of the shadow`s speed.

There are no absolutes for something so relative as a human life. There are no rules for something so gentle as a heart.

We accept gravity, aerodynamics, photosynthesis, thermodynamics, relativity, quantum mechanics, sexual reproduction, rain, thunder, earthquakes, volcanoes, and tidal waves, all based on science. But when it comes to the origin and nature of life itself we take leave of our senses for a trip into the supernatural. We literally lose our minds. Even

Las formas son vehículos e instrumentos, y los vehículos e instrumentos no pueden ser llamados buenos o malos sin un contexto.

In countries where there are no horses, donkeys are called horses.

El Sufi debe ser capaz de alternar su pensamiento entre lo relativo y lo Absoluto, lo aproximado y lo Real.

My curiosity is interfering with my work!" Einstein lamented in 1915 while trying to finalize his Theory of General Relativity.

One city can look at other cities relative to their city and learn something. It's a matter of sharing the patterns of what exists in one society based on landscape or cultural values versus other cities.

No person can escape Einsteinian relativity, and no soldier or veteran can escape the trauma of war's dislocation.

Everything is subjective, right? A question that's easy for you is hard for somebody else, and vice versa.

For two events separated in time, a geodesic is the natural path things would take in spacetime to connect one event to the other.

According to quantum mechanics, at the Planck scale length, instead of a gradually undulating geometry, there should be wild fluctuations and loops and handles of spacetime branching off, the sort of topography that the futuristic Ike encountered. General relativity cannot be used in such untamed territory.

With general relativity, we know that before gravity can act, spacetime has to deform. This process does not happen instantaneously. It takes time. Gravity waves travel at the speed of light. Gravitational effects can kick in at a given position only after the time it takes for a signal to travel there and distort spacetime.

The uncertainty principle tells us that you need high-momentum particles to probe or influence physical processes at short distances, and special relativity relates that momentum to a mass.

The uncertainty principle of quantum mechanics, coupled with the relations of special relativity, tell us that, using physical constants, we can relate a particle's mass, energy, and momentum to the minimum size of the region in which a particle of that energy can experience forces or interactions.

That's what's "special" in special relativity: the "special" inertial frames are only a small subset of all possible reference frames.

Movie Jesus is a whole lot different from Bible Jesus

The theory of relativity doesn't amount to a hill of beans when there's a bonfire in your shorts.

The clock has superpowers. It always seems to move too slowly. Look up at it and it will tell you the time. Look up an hour and a half later, and it will tell you two minutes have gone by.

To draw an analogy: a man's suffering is similar to the behavior of a gas. If a certain quantity of gas is pumped into an empty chamber, it will fill the chamber completely and evenly, no matter how big the chamber. Thus suffering completely fills the human soul and conscious mind, no matter whether the suffering is great or little. Therefore the "size" of human suffering is absolutely relative.

Instead of measuring freedom by whether our thoughts and actions are free from God, we are "free" as long as we are free relative to other created things, and then we build moral responsibility on that. They just changed the reference point.
