Proper noun
Heisenberg uncertainty principle
(physics, quantum mechanics) The principle that there is an absolute
limit on the combined accuracy of certain pairs of simultaneous, related
measurements, especially that of the position and momentum of a
particle. Originally posited as a problem of measurement, it was soon
refined as an inherent property of the universe.
Add "inherent" to The Age of Reason and you get The New Age.
