“The orthodox quantum theory is a recipe, a computational recipe, which has been fantastically successful.”— John Stewart Bell
“The ability to perform quantum computation is a fundamental feature of the laws of physics.”— Seth Lloyd
“Everything in space obeys the laws of physics. If you know these laws, and obey them, space will treat you kindly.”— Wernher von Braun
“The movement of the plane of oscillation of the pendulum is a real, mechanical, and visible proof of the rotation of the Earth.”— Léon Foucault
“Each element of a wave-front may be regarded as the center of a new disturbance.”— Christiaan Huygens
“The laws of physics are the program, and the initial state of the universe is the input.”— Seth Lloyd
“Our knowledge of the physical world is in a sense surrealistic; it is a union of the commonplace and the unexpected.”— Henry Norris Russell
“It seems likely that the electron is, in a certain sense, a simple particle and not a complex structure.”— Carl David Anderson
“The pilot-wave picture has the great merit, in my opinion, that it is deterministic.”— John Stewart Bell
“It would be better for the true physics if there were no mathematicians on earth.”— Daniel Bernoulli
“Nothing takes place in the world whose meaning is not that of some maximum or minimum.”— Leonhard Euler
“It is one thing to show that the Universe is described by a set of equations, but it is another to understand why those equations exist in the first place.”— John David Barrow
“The founding fathers of quantum theory... were, in my opinion, not distinguished by the care and precision of their language.”— John Stewart Bell
“The idea that there are 'systems' which are represented by state vectors, and 'apparatus' which are not, is surely something that we must grow out of.”— John Stewart Bell
“It is not right to tell the public that a central role for the observer in modern physics has been established.”— John Stewart Bell
“Space is not empty. It is full, a plenum as opposed to a vacuum, and is the ground for the existence of everything, including ourselves.”— David Bohm
