“An extension of Planck's ideas, due to Prof. Niels Bohr of Copenhagen, went on to suggest that… the ultimate particles of matter would be seen to move not like railway trains running smoothly on tracks, but like kangaroos hopping about in a field.”

“It is natural for a train to run on its tracks.”

Kalki Krishnamurthy (1899–1954) writer

Sivakozhundu of Tiruvazhundur (1939)
Context: It is natural for a train to run on its tracks. We get into a train because we believe that it will do that. But once in a while the train runs off the rails, and there’s an accident. Those who don’t actually witness such a happening can say, “No train will run off the rails, it is unnatural for it to do so”.

“In quantum theory, distance is inverse to energy, because you need particles of very high energy to probe very short distances. The inverse of the Planck energy is the Planck length.”
