Introduction to Quantum Mechanic
... It is not surprising to find that quantum mechanics does not predict the position of an electron exactly. Rather, it provides only a probability as to where the electron will be found. We shall illustrate the probability aspect in terms of the system of an electron confined to motion along a line o ...

... Figure 1 Erwin Schrödinger (left) and Niels Bohr. Bohr claimed that a momentum kick, imparted by any measurement of particle position, could explain the disappearance of quantum interference in ‘two-slit’ experiments. A new experiment1 shows that this effect is too small, and the disappearance must ...

He formulated the Heisenberg Uncertainty Principle, which states that it is impossible to know both the exact momentum and location of a particle simultaneously. The better you know one quantity, the more uncertain you must be of the other. 22. Accordin ...
