Albert Einstein was never clear if he believed in time travel, but had he raised a toddler, he certainly would have.

Although I am a typical loner in my daily life, my awareness of belonging to the invisible community of those who strive for truth, beauty, and justice has prevented me from feelings of isolation.

Anyone who doesn't take truth seriously in small matters cannot be trusted in large ones either.

Asked in 1919 whether it was true that only three people in the world understood the theory of general relativity, [Eddington] allegedly replied: 'Who's the third?

— Arthur Stanley Eddington

By far the most important consequence of the conceptual revolution brought about in physics by relativity and quantum theory lies not in such details as that meter sticks shorten when they move or that simultaneous position and momentum have no meaning, but in the insight that we had not been using our minds properly and that it is important to find out how to do so.

Einstein, twenty-six years old, only three years away from crude privation, still a patent examiner, published in the Annalena her Physic in 1905 five papers on entirely different subjects. Three of them were among the greatest in the history of physics. One, very simple, gave the quantum explanation of the photoelectric effect—it was this work for which, sixteen years later, he was awarded the Nobel Prize. Another dealt with the phenomenon of Brownian motion, the apparently erratic movement of tiny particles suspended in a liquid: Einstein showed that these movements satisfied a clear statistical law. This was like a conjuring trick, easy when explained: before it, decent scientists could still doubt the concrete existence of atoms and molecules: this paper was as near to a direct proof of their concreteness as a theoretician could give. The third paper was the special theory of relativity, which quietly amalgamated space, time, and matter into one fundamental unity. This last paper contains no references and quotes to authority. All of them are written in a style unlike any other theoretical physicists. They contain very little mathematics. There is a good deal of verbal commentary. The conclusions, the bizarre conclusions, emerge as though with the greatest of ease: the reasoning is unbreakable. It looks as though he had reached the conclusions by pure thought, unaided, without listening to the opinions of others. To a surprisingly large extent, that is precisely what he had done.

Honestly, I cannot understand what people mean when they talk about the freedom of the human will. I have a feeling, for instance, that I will something or other; but what relation this has with freedom I cannot understand at all. I feel that I will to light my pipe and I do it; but how can I connect this up with the idea of freedom? What is behind the act of willing to light the pipe? Another act of willing? Schopenhauer once said: Her Mensch Kane was her will; her Kane Abel night pollen was her will (Man can do what he will, but he cannot will what he wills).

I believe in you and me. I'm like Albert Schweitzer and Bertrand Russell and Albert Einstein in that I have a respect for life -- in any form. Furthermore, I believe in nature, in the birds, the sea, the sky, in everything I can see or that there is real evidence for. If these things are what you mean by God, then I believe in God. But I don't believe in a personal God to whom I look for comfort or for a natural on the next roll of the dice.

If it's true what is said, that only the wise discover the wise, then it must also be true that the lone wolf symbolizes either the biggest fool on the planet or the biggest Einstein on the planet.

If you can bring yourself to apply your imagination to finding the possible favorable outcomes of undesired developments, even if only as an exercise, you'll see that it fosters creativity. This suggestion is much more than a way to find the silver lining our grandmothers encouraged us to look for. I include it in this book because creativity is linked to intuition, and intuition is the way out of the most serious challenges you might face. Albert Einstein said that when you follow intuition, The solutions come to you, and you don’t know how or why.
