“We are all in the depths of a cave, chained by our ignorance, by our prejudices, and our weak senses reveal to us only shadows. If we try to see further, we are confused: we are unaccustomed. But we try. This is science.”
“You don’t get to new places by following established tracks.”
“Our culture is foolish to keep science and poetry separated: they are two tools to open our eyes to the complexity and beauty of the world.”
“The apparent determinism of the macroscopic world is due only to the fact that the microscopic randomness cancels out on average, leaving only fluctuations too minute for us to perceive in everyday life.”
“Quantum mechanics reveals to us that the more we look at the detail of the world, the less constant it is. The world is not made up of tiny pebbles. It is a world of vibrations, a continuous fluctuation, a microscopic swarming of fleeting microevents.”
“The world of quantum mechanics is not a world of objects: it is a world of events.”
“We must learn to think of the world not as something which changes in time but in some other way. Things change only in relation to one another. At a fundamental level, there is no time.”
“It is always heat and only heat that distinguishes the past from the future.”
“Science is born from this act of humility: not trusting blindly in our past knowledge and our intuition. Not believing what everyone says. Not having faith in the accumulated knowledge of our fathers and grandfathers.”
“The world revealed by quantum gravity is a new and strange one – still full of mystery, but coherent with its simple and clear beauty.”
