"We saw that radiation cannot suitably be pictured as particles when it is traveling through space. There is a corresponding property for electrons; these should not be pictured as waves so long as the…"

"In every previous application of the quantum law, Planck's law, that the energy is h times the frequency, had been used to deduce the energy of a quantum when the frequency of the radiation was alread…"

"It can hardly be a matter for surprise that our race has not succeeded in solving any large part of its most difficult problems in the first millionth part of its existence. Perhaps life would be a du…"

"Life exists in the universe only because the carbon atom possesses certain exceptional properties."

"...a detailed mathematical discussion shows that whatever kind of wave-packet we select to represent the electron, the product of the two uncertainties of position and momentum can never be less than …"

"Faraday, Maxwell, Larmor and a great number of others tried to explain electromagnetic action on these lines, but all attempts failed, and it began to seem impossible that any properties of ether coul…"

"And the substance out of which this bubble is blown, the soap-film, is empty space welded onto empty time."

"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 tra…"
