Uncertainty Principle


("The Crystal Ball" by John William Waterhouse)



« Uncertainty Principle » gets its title from Heisenberg's quantum mechanics principle which states by precise inequalities that certain pairs of physical properties, like position and momentum, cannot simultaneously be known to arbitrary precision. That is, the more precisely one property is measured, the less precisely the other can be measured. In other words, the more you know the position of a particle, the less you can know about its velocity,
