Quotes from Stephen Hawking

My prediction is that we will know the mind of God by the end of this century.

En el instante del Big Bang, algo maravilloso sucedió con el tiempo. El tiempo mismo comenzó.

realismo dependiente del modelo», basada en la idea de que nuestros cerebros interpretan los datos de los órganos sensoriales elaborando un modelo del mundo. Cuando el modelo explica satisfactoriamente los acontecimientos tendemos a atribuirle, a él y a los elementos y conceptos que lo integran, la calidad de realidad o verdad absoluta.

What happened before the beginning ? What was God doing before he made the world? Was he preparing Hell for people who asked such questions?

Stephen Hawking Quotes Look up at the stars and not down at your feet. Try to make sense of what you see, and wonder about what makes the universe exist. Be curious. Stephen Hawking

Propria noastr? existen?? impune reguli care determin? din ce loc È™i din ce moment avem posibilitatea s? observ?m universul. Altfel spus, existenÈ›a noastr? restricÈ›ioneaz? caracteristicile acelui tip de mediu în care ne afl?m.

Hamlet said, "I could be bounded in a nutshell, and count myself a king of infinite space." I think what he meant was that although we humans are very limited physically, particularly in my own case, our minds are free to explore the whole universe, and to boldly go where even Star Trek fears to tread.

remember to look up at the stars and not at your feet. Try to make sense of what you see and wonder about what makes the the universe exist. Be curious. And however difficult life may seem, there is always something you can do and succeed at. It matters that you don't just give up. Unleash your imagination. Shape the future.

Ne f?urim concepte mentale despre c?minul nostru, despre copaci, despre al?i oameni, despre electricitatea care curge din prize, despre atomi, molecule ?i alte universuri. Aceste concepte mentale sunt singura realitate pe care o cunoa?tem.

Caenorhabditis elegans—a simple creature made of only 959 cells? It probably never thinks, "That was damn tasty bacteria I got to dine on back there

I believe the universe is governed by the laws of science. These laws may have originally been decreed by God, but it appears that he has since left the universe to evolve according to them and does not now intervene in it.

Las teorías cuánticas han resultado ser notablemente precisas en la predicción de acontecimientos a dichas escalas, y también reproducen las predicciones de las viejas teorías clásicas cuando son aplicadas al mundo macroscópico de la vida corriente.

In general relativity, bodies always follow straight lines in four-dimensional space-time, but they nevertheless appear to us to move along curved paths in our three-dimensional space. (This is rather like watching an airplane flying over hilly ground. Although it follows a straight line in three-dimensional space, its shadow follows a curved path on the two-dimensional ground.)

It's like winning a lottery. Although the odds are astronomical, most weeks, someone hits the jackpot.

There are at least three different arrows of time. First, there is the thermodynamic arrow of time, the direction of time in which disorder or entropy increases. Then, there is the psychological arrow of time. This is the direction in which we feel time passes, the direction in which we remember the past but not the future. Finally, there is the cosmological arrow of time. This is the direction of time in which the universe is expanding rather than contracting.

Corpuri precum stelele sau g?urile negre nu pot ap?rea din nimic. Dar un întreg univers poate.

Según Feynman, un sistema no tiene una sola historia, sino todas las historias posibles.

Why is there something rather than nothing? Why do we exist? Why this particular set of laws and not some other?

In an unchanging universe a beginning in time is something that has to be imposed by some being outside the universe;

Noi cre?m istoria prin observa?iile noastre, iar nu istoria ne creeaz? pe noi.

Our subjective sense of the direction of time, the psychological arrow of time, is therefore determined within our brain by the thermodynamic arrow of time. Just like a computer, we must remember things in the order in which entropy increases. This makes the second law of thermodynamics almost trivial. Disorder increases with time because we measure time in the direction in which disorder increases. You can't have a safer bet than that!

contains on average some one hundred billion stars. If a star were a grain of salt, you could fit all the stars visible to the naked eye on a teaspoon, but all the stars in the universe would fill a ball more than eight miles wide.

We can't predict what that will be or when we will find it because if we knew that, we would have found it already!

Quiet people have the loudest minds
