A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die.
— Max Planck, as quoted by Adam Grant in his book “Originals”.
We must be clear that when it comes to atoms, language can be used only as in poetry. The poet, too, is not nearly so concerned with describing facts as with creating images and establishing mental connections.
— Niels Bohr, Danish physicist.
