Quotes About Relativity

Everything is relative. Is the Internet fast? Not for most people. Is it always on? Yes, for cable modem and DSL users but that represents a tiny percentage of users.

If beauty is relative, then any and everything when compared to the beauty of God is absolutely hideous.

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 of Sommerfeld's fine-structure formula "served also as an indirect confirmation of Einstein's relativistic formula for the velocity dependence of inertia mass.

Time travel used to be thought of as just science fiction, but Einstein's general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out.

Two people can see the same thing, disagree, and yet both be right. It's not logical; it's psychological.

There are no absolutes, and your way is neither the only way nor the right way.

Good and bad aren't absolutes. They are beliefs, judgements, ideas based on limited knowledge as well as on the inclinations of our minds.

If all ideas are limited to their own time and place, then this must also be true for the idea that all ideas are limited to their own time and place.

But what is good and what is bad? That has become increasingly confusing in this age of relativity. There seem to be no mores that are considered universal. Can that be so? Look at the Ten Commandments.

At rest, we know that its circumference is equal to p times the diameter. Once the merry-go-round is set into motion, however, the outer rim travels faster than the interior and hence, according to relativity, should shrink more than the interior, distorting the shape of the merry-go-round. This means that the circumference has shrunk and is now less than p times the diameter; that is, the surface is no longer flat. Space is curved.

According to Einstein, there is no gravitational pull. The earth warps the space-time continuum around our bodies, so space itself pushes us down to the floor. Thus, it is the presence of matter that warps space around it, giving us the illusion that there is a gravitational force pulling on neighboring objects.

Einstein's Cosmos

Finalmente, Einstein creó dos grandes teorías. La primera fue la relatividad especial, que describía las propiedades de los rayos de luz en el espacio-tiempo e introducía una simetría basada en rotaciones en cuatro dimensiones. La segunda fue la relatividad general, en la que la gravedad se revela como la curvatura del espacio-tiempo.

El matrimonio entre la relatividad y la teoría cuántica ha estado casi un siglo perturbando a los físicos, pero la simetría entre fermiones y bosones, denominada «supersimetría», nos permite anular muchos de estos infinitos entre sí.

And at the speed of light, you have taken the fastest possible journey to the stars. From your point of view, the trip is instantaneous.

el tiempo se frena más dentro de un cohete cuanto más rápido se mueve.

La atracción gravitatoria es una ilusión. Por ejemplo, quizá ahora esté sentado en una silla, leyendo este libro. Por lo general, diría que la gravedad tira de usted hacia el asiento, y por eso no sale volando hacia el espacio. Pero Einstein diría que está sentado en la silla porque la Tierra deforma la masa de espacio sobre su cabeza, y esa deformación le empuja hacia el suelo.

Imaginemos también unas hormigas que se mueven sobre una hoja de papel arrugada. No pueden moverse en línea recta. Puede que sientan una fuerza que tira de ellas continuamente, pero nosotros, que miramos las hormigas desde arriba, vemos que no hay ninguna fuerza en absoluto. Esta es la idea que surge de lo que Einstein llamó «relatividad general»: el espacio-tiempo se deforma por masas pesadas, lo que provoca la ilusión de la fuerza gravitatoria.

A pesar de lo descabellado de la teoría de cuerdas, uno de los aspectos que la ha mantenido con vida es que combina satisfactoriamente los dos grandes pilares de la física, la relatividad general y la teoría cuántica, ofreciéndonos una teoría finita de la gravitación cuántica. De ahí viene todo el entusiasmo.

So this is one goal of modern physics: to create a quantum theory of gravity where the quantum corrections are finite and calculable. In other words, Einstein's theory of gravity allows for the formation of wormholes, which may one day give us shortcuts through the galaxy. But Einstein's theory cannot tell us if these wormholes are stable or not. To calculate these quantum corrections, we need a theory that combines relativity with the quantum theory.

Humor: the divine flash that reveals the world in its moral ambiguity and man in his profound incompetence to judge others; humor: the intoxicating relativity of human things; the strange pleasure that conies of the certainty that there is no certainty. But humor, to recall Octavio Paz, is the great invention of the modern spirit. It has not been with us forever, and it won't be with us forever either. With a heavy heart, I imagine the day when Panurge no longer makes people laugh.

a humor az emberi dolgok viszonylagosságának mámora; különös gyönyör?ség, mely abból a bizonyosságból fakad, hogy nincs bizonyosság.

O humor: o relâmpago divino que descobre o mundo na sua ambiguidade moral e o homem na sua profunda incompetência para julgar os outros; o humor: a embriaguez da relatividade das coisas humanas; o estranho prazer resultante da certeza de que não há certeza.

Atâta timp cât nu-i adult, omul continu? s? aspire mult? vreme la unitatea È™i siguranÈ›a acestui univers, împlinit de el în întregime în m?runtaiele mamei, È™i e cuprins de spaima relativit??ii lumii adulte, de care e înghiÈ›it ca o pic?tur? c?zut? într-un ocean al nep?s?rii. C?ci tinerii sunt, de felul lor, moniÈ™ti pasionaÈ›i, mesageri ai absolutului (...).
