I have tried to read philosophers of all ages and have found many illuminating ideas but no steady progress toward deeper knowledge and understanding. Science, however, gives me the feeling of steady progress: I am convinced that theoretical physics is actual philosophy. It has revolutionized fundamental concepts, e.g., about space and time (relativity), about causality (quantum theory), and about substance and matter (atomistics), and it has taught us new methods of thinking (complementarity) which are applicable far beyond physics.

When you hurt someone, it initiates a chemical reaction in that person’s body that changes his/her mental condition. That means you are disturbing the arrangement of subatomic particles like protons and neutrons. These particles are the part of grid that holds all the particles of the Universe. To reset this disturbance of grid caused by you and according to laws of nature, Universe will go to source and destroy it. So, it’s better to say a simple word “sorry” and reset the arrangement yourself before Universe.

He was a physicist, more precisely an astrophysicist, diligent and eager but without illusions: the Truth lay beyond, inaccessible to our telescopes, accessible to the initiates. This was a long road which he was traveling with effort, wonderment, and profound joy. Physics was prose: elegant gymnastics for the mind, mirror of Creation, the key to man's dominion over the planet; but what is the stature of Creation, of man and the planet? His road was long and he had barely started up it, but I was his disciple: did I want to follow him?

While the Copernican principle comes with no guarantees that it will forever guide us to cosmic truths, it's worked quite well so far: not only is Earth not in the center of the solar system, but the solar system is not in the center of the Milky Way galaxy, the Milky Way galaxy is not in the center of the universe, and it may come to pass that our universe is just one of many that comprise a multiverse. And in case you're one of those people who thinks that the edge may be a special place, we are not at the edge of anything either.

The standard cosmological theory--an expanding universe--does not really solve the problem of God. It simply makes it more problematical. Once the creator-creation model is discarded as primitive mythology, we still have not touched the ancient conundrum, ex nihilo nihil fit: nothing comes from nothing, and the "axiom" that "Nothing is unstable' rivals in scholastic absurdity anything Aquinas may have said eight hundred years ago and can only be postulated given the reality of something, whereby it becomes a self-evident and unarguable tautology.

I'll be looking for you, Will, every moment, every single moment. And when we do find each other again, we'll cling together so tight that nothing and no one'll ever tear us apart. Every atom of me and every atom of you... We'll live in birds and flowers and dragonflies and pine trees and in clouds and in those little specks of light you see floating in sunbeams... And when they use our atoms to make new lives, they wont' just be able to take one, they'll have to take two, one of you and one of me, we'll be joined so tight...

Einstein's paper on the photoelectric effect was the work for which he ultimately won the Nobel Prize. It was published in 1905, and Einstein has another paper in the very same journal where it appeared - his other paper was the one that formulated the special theory of relativity. That's what it was like to be Einstein in 1905; you publish a groundbreaking paper that helps lay the foundation of quantum mechanics, and for which you later win the Nobel Prize, but it's only the second most important paper that you publish in that issue of the journal.

We absolutely must leave room for doubt or there is no progress and there is no learning. There is no learning without having to pose a question. And a question requires doubt. People search for certainty. But there is no certainty. People are terrified — how can you live and not know? It is not odd at all. You only think you know, as a matter of fact. And most of your actions are based on incomplete knowledge and you really don't know what it is all about, or what the purpose of the world is, or know a great deal of other things. It is possible to live and not know.

Some people are ignorant of the world but educated in Scripture, and are therefore prone to missing the relevance of Scripture - these sometimes, later, amidst life's challenges and doubts, turn from the faith; other people are ignorant of Scripture but educated in the world, and are therefore prone to missing the truth of Scripture - they are often those who ridicule the faith. The apologist stands somewhere in the center. He articulates where some are prone to understanding the truth in beauty, others the beauty in truth - that of a spiritual Creator in relation to his scientific creation.

Have you ever wanted to learn Geometry, Calculus, Physics, German, and the mystical teachings of Orafoura? Well, now you can! Just not with this book. Well, except for the mystical bit. This book is guaranteed to cost you, or your money back. If there is ever a book that deserves to be burned, this is it. And while you are lighting a fire, why don't you also set your imagination ablaze? You can start by taking a gasoline shower and sprinting naked through Flint, Michigan. Or Phoenix. After all, the only way you'll ever be able to reach your true potential is with a stepladder and a stretch.

[On the practical applications of particle physics research with the Large Hadron Collider.]Sometimes the public says, 'What's in it for Numero Uno? Am I going to get better television reception? Am I going to get better Internet reception?' Well, in some sense, yeah. ... All the wonders of quantum physics were learned basically from looking at atom-smasher technology. ... But let me let you in on a secret: We physicists are not driven to do this because of better color television. ... That's a spin-off. We do this because we want to understand our role and our place in the universe.

If and when all the laws governing physical phenomena are finally discovered, and all the empirical constants occurring in these laws are finally expressed through the four independent basic constants, we will be able to say that physical science has reached its end, that no excitement is left in further explorations, and that all that remains to a physicist is either tedious work on minor details or the self-educational study and adoration of the magnificence of the completed system. At that stage physical science will enter from the epoch of Columbus and Magellan into the epoch of the National Geographic Magazine!

Wolfgang Pauli, in the months before Heisenberg's paper on matrix mechanics pointed the way to a new quantum theory, wrote to a friend, "At the moment physics is again terribly confused. In any case, it is too difficult for me, and I wish I had been a movie comedian or something of the sort and had never heard of physics." That testimony is particularly impressive if contrasted with Pauli's words less than five months later: "Heisenberg's type of mechanics has again given me hope and joy in life. To be sure it does not supply the solution to the riddle, but I believe it is again possible to march forward.

There was yet another disadvantage attaching to the whole of Newton’s physical inquiries, ... the want of an appropriate notation for expressing the conditions of a dynamical problem, and the general principles by which its solution must be obtained. By the labours of LaGrange, the motions of a disturbed planet are reduced with all their complication and variety to a purely mathematical question. It then ceases to be a physical problem; the disturbed and disturbing planet are alike vanished: the ideas of time and force are at an end; the very elements of the orbit have disappeared, or only exist as arbitrary characters in a mathematical formula.

Quantum fluctuations are, at their root, completely a-causal, in the sense that cause and effect and ordering of events in time is not a part of how these fluctuations work. Because of this, there seem not to be any correlations built into these kinds of fluctuations because 'law' as we understand the term requires some kind of cause-and-effect structure to pre-exist. Quantum fluctuations can precede physical law, but it seems that the converse is not true. So in the big bang, the establishment of 'law' came after the event itself, but of course even the concept of time and causality may not have been quite the same back then as they are now.
