  1. Bell himself managed to devise such a proof which rejects all models of reality possessing the property of "locality". This proof has since become known as Bells theorem. It asserts that no local model of reality can underlie the quantum facts. Bell's theorem says that reality must be non-local.

    p. 212

  2. Physicists continue to debate whether Bell's theorem is airtight or not. However, the real question is not whether Bell can prove beyond doubt that reality is non-local, but whether the world is in fact no-local.

    p. 238

  3. A universe that displays local phenomena but upon a non-local reality is the only sort of world consistent with known facts and Bell's proof.

    p. 230

  4. No local reality can explain the type of world we live in.

    p. 245

  5. The simplicity of Bell's proof opens it to everyone, not just physicists and mathematicians.

    p. 215

  6. If a friend in Texas seals a silver coin in one envelope and a gold coin in another and mails the envelopes to Tokyo and London, the instant you open you envelope in Japan you know the contents of my envelope in England. But opening your letter causes no physical change in England (faster-than-light or otherwise) but merely involves a change in your knowledge concerning something happening far away and outside your control.

    p. 171

  7. Legendary King Midas never knew the feel of silk or a human hand after everything he touched turned to gold. Humans are stuck in a similar Midas-like predicament: we can't directly experience the true texture of reality because everything we touch turns to matter.

    p. 194

  8. So minuscule is the scale of quantum events compared to the actions of everyday life that it's a wonder humans ever found out about the quantum world at all.

    p. 150

  9. Strictly speaking, there are no "measurements" in the world, only correlations.

    p. 174

  10. Quantum physics emerged from the Stone Age with an embarrassment of riches - three quantum theories, each claiming to explain the world. As it turned out, all three were right.

    p. 42

  11. Physicists cannot explain atoms to their children, not because we are ignorant but because we know too much.

    p. 197

  12. Though today's quantum theory shows no sign of weakness, someday it may collapse.

    p. 52
