Quotes About Einstein

singularities, he asserted, "are a place in which the fiery marriage of Einstein's relativistic laws with the quantum laws is consummated.

I know exactly what Einstein meant when he said, "Dancers are the athletes of God." You three look like angels. I can't wait to see you dancing in the Christmas concert.

Einstein told me I was smart. Maybe I'd get a tattoo of those words.

In his youth Albert Einstein spent a year loafing aimlessly. You don't get anywhere by not 'wasting' time- something, unfortunately, that the parents of teenagers tend frequently to forget.

A moving object therefore experiences a shorter duration than a stationary one: a watch marks fewer seconds, a plant grows more slowly, a young man dreams less. For a moving object, time contracts.

Those who defend this way of thinking about reality—eternalism—frequently cite Einstein, who in a famous letter writes: For people like us who believe in physics the distinction between past, present and future is only a stubbornly persistent illusion.

When Einstein objected to quantum mechanics by remarking that "God does not play dice," Bohr responded by admonishing him, "Stop telling God what to do." Which means: Nature is richer than our metaphysical prejudices. It has more imagination than we do.

When Lemaître defends the idea that the universe is expanding, and Einstein does not believe it, one of the two is wrong; the other, right. All of Einstein's results, his fame, his influence on the scientific world, his immense authority, count for nothing. The observations prove him wrong, and it's game over. An obscure Belgian priest is right. It is for this reason that scientific thinking has power.

And it is at this point that an extraordinary idea occurred to him, a stroke of pure genius: the gravitational field is not diffused through space; the gravitational field is that space itself. This is the idea of the general theory of relativity. Newton's "space," through which things move, and the "gravitational field" are one and the same thing.

Empowered by new conceptual tools and by mathematics, Einstein writes the equations which describe Democritus's void and finds for its 'certain physics' a colourful and amazing world where universes explode, space collapses into bottomless holes, time slows down in the vicinity of a planet, and the boundless expanses of interstellar space ripple and sway like the surface of the sea

In technical terms, we say that Einstein has understood that "absolute simultaneity" does not exist: there is no collection of events in the universe that exist "now.

Let's begin with a simple fact: time passes faster in the mountains than it does at sea level.

Ten years before understanding that time is slowed down by mass,21 Einstein had realized that it was slowed down by speed.22 The consequence of this discovery for our basic intuitive perception of time is the most devastating of all.

the spatiotemporal entity of Einstein.

The key fact that Einstein understood is that this quarter of an hour is inevitable: there is no way of reducing it. It is woven into the texture of the events of space and of time: we cannot abbreviate it, any more than we can send a letter to the past.

Quando Einstein muore, Bohr, il suo grandissimo rivale, ha parole di commovente ammirazione. Quando pochi anni dopo muore Bohr, qualcuno prende una fotografia della lavagna nel suo studio: c'è un disegno. Rappresenta la «scatola piena di luce» dell'esperimento mentale di Einstein. Fino all'ultimo, la voglia di confrontarsi e capire di più. Fino all'ultimo, il dubbio.

With a great deal of effort, seeking help from friends better versed in mathematics than himself, Einstein learns Riemann's math—and writes an equation where R is proportional to the energy of matter. In words: spacetime curves more where there is matter. That is it.

But it is not only space that curves: time does too. Einstein predicts that time on Earth passes more quickly at higher altitude, and more slowly at lower altitude.

Ama bükülen yaln?zca uzay de?ildir; zaman da bükülür. Einstein zaman?n yüksekteki bir konumda, dünyaya yak?n, daha alçak bir durumdan daha h?zl? akt???n? öngörür.

Einstein'?n denklemi uzay?n dura?an olamayaca??n?, geni?lemek zorunda oldu?unu gösterir. (...) Ayn? denklem geni?lemenin minicik ve çok s?cak genç bir evrenin patlamas?yla tetiklendi?ini de öngörür: Bu da Büyük Patlama'd?r.

There is our past: all the events that happened before what we can witness now. There is our future: the events that will happen after the moment from which we can see the here and now. Between this past and this future there is an interval that is neither past nor future and still has a duration: fifteen minutes on Mars; eight years on Proxima b; millions of years in the Andromeda galaxy. It is the expanded present.28 It is perhaps the greatest and strangest of Einstein's discoveries.

This is a tremendous result: on the one hand, taking quantum mechanics into account resolves the problems generated by the infinities of Einstein's theory of gravity, that is to say, the singularities. On the other, taking gravity i to account solves the problems generated by quantum field theory, that is to say, the divergences. Far from being contradictory, as they at first seemed, the two theories each offer the solution to the problems posed by the other!

If we try to put together what we have learned in the twentieth century about the physical world, the clues point toward something profoundly different from our instinctive understanding of matter, space, and time.

Einstein ?????n paketlerden, ???k parçac?klar?ndan olu?tu?unu gösterdi. Bunlara bugün "fotonlar" diyoruz.
