Many legends have arisen over the years in regards to physics and physicists, some of which are quite false. This list collects some of these myths and misconceptions, and provides further information to try to clarify the truths behind them.

### Quantum Physics Means the World is Completely Random

There are several aspects of quantum physics which easily lends it to misinterpretation. The first is Heisenberg’s Uncertainty Principle, which very specifically relates to the proportional relationship of quantities – such as position measurement and momentum measurement – within a quantum system. Another is the fact that quantum physics field equations yield a range of “probabilities” of what the outcome is. Together, the two have led some postmodern thinkers to believe that reality itself is completely random.

In fact, though, the probabilities go away when you combine them and expand the mathematics into our own macroscopic world. While the tiny world may be random, the sum of all that randomness is an orderly universe.
