Stephen Hawking
Stephen William Hawking, CH, CBE, FRS, FRSAis an English theoretical physicist, cosmologist, author and Director of Research at the Centre for Theoretical Cosmology within the University of Cambridge. His scientific works include a collaboration with Roger Penrose on gravitational singularity theorems in the framework of general relativity, and the theoretical prediction that black holes emit radiation, often called Hawking radiation. Hawking was the first to set forth a theory of cosmology explained by a union of the general theory of...

I wouldnt be here today if it were not for the NHS, I have received a large amount of high-quality treatment without which I would not have survived.
To boldly go where no one has gone before
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!
A theory is a good theory if it satisfies two requirements: it must accurately describe a large class of observations on the basis of a model that contains only a few arbitrary elements, and it must make definite predictions about the results of future observations.
Why does the universe go to all the bother of existing?
Only a very few would allow creatures like us to exist. Thus our presence selects out from this vast array only these universes that are compatible without existence. Although we are puny and insignificant on the scale of the cosmos, this makes us in a sense, the lords of creation.
A model is a good model if first it interprets a wide range of observations in terms of a simple and elegant model, and second if the model makes definite predictions that can be tested, and possibly falsified, by observation.
It is said that there's no such thing as a free lunch. But the universe is the ultimate free lunch.
One can imagine that God created the universe at literally any time in the past. On the other hand, if the universe is expanding, there may be physical reasons why there had to be a beginning. One could imagine that God created the universe at the instant of the big bang, or even afterwards in just such a way as to make it look as though there had been a big bang, but it would be meaningless to suppose that it was created before the big bang. An expanding universe does not preclude a creator, but it does place limits on when he might have carried out his job!
Maybe I'm being a bit harsh on philosophers, but they have not been very kind to me... I have been variously called nominalist, an instrumentalist, a positivist, a realist, and several other ists. The technique seems refutation by denigration: If you can attach a label to my approach, you don't have to say what is wrong with it... I am sure that Einstein, Heisenberg and Dirac didn't worry about whether they were realists or instrumentalists.
Science does not deny religion, it just offers a simpler alternative.
Sometimes I wonder if I'm as famous for my wheelchair and disabilities as I am for my discoveries
Without imperfection, you or I would not exist.
