Quotes from Stephen Hawking

Hot?rârile noastre sunt adesea iraÈ›ionale sau se bazeaz? pe o analiz? incorect? a consecinÈ›elor alegerii. De aceea în lume e atâta dezordine.

any normal object is forever confined by relativity to move at speeds slower than the speed of light. Only light, or other waves that have no intrinsic mass, can move at the speed of light.

Unfortunately, however, these two theories are known to be inconsistent with each other—they cannot both be correct.

It means the universe itself, in all its mind-boggling vastness and complexity, could simply have popped into existence without violating the known laws of nature.

Contanto que o universo tenha tido um início, podemos supor que houve um criador. Mas, se o universo fosse de fato absolutamente contido em si mesmo, sem contorno nem borda, ele não teria início nem fim: ele simplesmente seria. Nesse caso, qual é o papel de um criador?

Opening up the thrill and wonder of scientific discovery, creating innovative and accessible ways to reach out the widest audience possible, greatly increases the chances of finding and inspiring the new Einstein. Wherever she might be.

Când analiz?m mai atent felul în care ne facem observaÈ›iile È™i ne construim concepte despre ceea ce ne înconjoar?, ajugem s? ne întreb?m dac? avem motive întemeiate s? credem c? exist? o realitate obiectiv?.

but also that it is possible that nothing caused the Big Bang. Nothing.

I have been praised and criticised, but never ignored.

Na teoria da relatividade, não existe tempo absoluto único; em vez disso, cada indivíduo tem sua própria medida de tempo, que depende de onde ele se encontra e de como está se movendo.

Our only chance of long-term survival is not to remain inward-looking on planet Earth, but to spread out into space.

Do the laws governing the universe allow us to predict exactly what is going to happen to us in the future? The short answer is no, and yes. In principle, the laws allow us to predict the future. But in practice the calculations are often too difficult.

But it would be an empty universe indeed if it were not for the people I love, and who love me. Without them, the wonder of it all would be lost on me

Things are as they are because we are

Our future is a race between the growing power of our technology and the wisdom with which we use it. Let's make sure that wisdom wins.

Prof Stephen Hawking, one of Britain's pre-eminent scientists, has said that efforts to create thinking machines pose a threat to our very existence. He told the BBC:The development of full artificial intelligence could spell the end of the human race.

The earth's shadow on the moon was always round, which would be true only if the earth was spherical. If the earth had been a flat disk, the shadow would have been elongated and elliptical, unless the eclipse always occurred at a time when the sun was directly under the center of the disk.

This result was very convenient for Marxist–Leninist dialectical materialism

Suntem cu to?ii pl?smuiri ale visului cuiva.

Cada vez que observamos novos experimentos coincidirem com as previsões, a teoria sobrevive e nossa confiança nela aumenta; porém, se em algum momento uma nova observação a contradiz, temos de abandonar a teoria ou modificá-la. Pelo

Our modern picture of the universe dates back to only 1924, when the American astronomer Edwin Hubble demonstrated that ours was not the only galaxy.

developed only because of the lucky chance that there have been no major collisions in the last sixty-six million years. Other planets in the galaxy, on which life has developed, may not have had a long enough collision-free period to evolve intelligent beings.

El afán por descubrir alimenta la creatividad en todos los campos, no sólo en la ciencia. Si llegáramos a la meta, el espíritu humano se marchitaría y moriría.

Nitekim kuantum mekaniÄŸi televizyon ve bilgisayar gibi elektronik aletlerin temel bileÅŸenleri olan transistörlerin ve mikroçiplerin davran???na hükmettiÄŸi gibi, modern kimyan?n ve biyolojinin de temelini oluÅŸturur.
