Stephen Hawking Quotes: 23

• Life would be tragic if it weren't funny.

• One, remember to look up at the stars and not down at your feet. Two, never give up work. Work gives you meaning and purpose and life is empty without it. Three, if you are lucky enough to find love, remember it is there and don't throw it away.

• The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.

• I hope I have helped to raise the profile of science and to show that physics is not a mystery but can be understood by ordinary people.

• Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and makes a universe for them to describe? The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?

• My expectations were reduced to zero when I was 21. Everything since then has been a bonus."[The Science of Second-Guessing (New York Times Magazine Interview, December 12, 2004)]

• I believe the simplest explanation is, there is no God. No one created the universe and no one directs our fate. This leads me to a profound realization that there probably is no heaven and no afterlife either. We have this one life to appreciate the grand design of the universe and for that, I am extremely grateful.

  A Brief History of Time

• So long as the universe had a beginning, we could suppose it had a creator. But if the universe is really completely self-contained, having no boundary or edge, it would have neither beginning nor end: it would simply be. What place, then, for a creator?

• What I have done is to show that it is possible for the way the universe began to be determined by the laws of science. In that case, it would not be necessary to appeal to God to decide how the universe began. This doesn't prove that there is no God, only that God is not necessary.

• It is not clear that intelligence has any long-term survival value.

• Keeping an active mind has been vital to my survival, as has been maintaining a sense of humor.

• The human race is just a chemical scum on a moderate-sized planet, orbiting around a very average star in the outer suburb of one among a hundred billion galaxies. We are so insignificant that I can't believe the whole universe exists for our benefit. That would be like saying that you would disappear if I closed my eyes.

• why are we here?where do we come from?traditionally,these are questionsfor philosophy,but philosophy is dead

• The people who actually make the advances in theoretical physics don't think in these categories that the philosophers and the historians of science subsequently invent for them
