It from Bit

In the Proceedings of the Third International Symposium on the Foundations of Quantum Mechanics held in Tokyo, 1989, and published in 1990, American physicist John Archibald Wheeler delivered a paper entitled "Information, Physics, Quantum: The Search for Links."

In the paper Wheeler wrote: "Otherwise stated, every physical quantity, every it, derives its ultimate significance from bits, binary yes-or-no indications, a conclusion which we epitomize in the phrase, it from bit." (source: History of Information)
