the Heisenberg principle (which states, roughly, that an act of observation produces changes in what is observed),

Another of the main tenets of quantum physics is the uncertainty principle, formulated by Werner Heisenberg in 1926. The uncertainty principle tells us that there are limits to our ability to simultaneously measure certain data, such as the position and velocity of a particle. According to the uncertainty principle, for example, if you multiply the

In a famous experiment conducted less than a year after Heisenberg’s (1925) enunciation of the Principle of Indeterminacy, Winnie- the-Pooh (1926) probed the depths of his honey-potto be certain that it was truly honey within, all the way to the bottom. The probe was successful. On completion of the probing, however, the honey-pot nolonger

Pondering the physical meaning of noncommutativity led Heisenberg in 1927 to an extraordinary new law of nature, which stated that the position and momentum of a particle cannot both ever have exact values at the same time.

Heisenberg showed that the uncertainty in the position of the particle times the uncertainty in its velocity times the mass of the particle can never be smaller than a certain quantity, which is known as Planck’s constant. Moreover, this limit does not depend on the way in which one tries to measure the position or velocity of the particle, or on

“It is impossible to design an apparatus to determine which hole the electron passes through, that will not at the same time disturb the electrons enough to destroy the interference pattern.” If an apparatus is capable of determining which hole the electron goes through, it cannot be so delicate that it does not disturb the pattern in an essential
