The Heisenberg uncertainty principle

The Heisenberg uncertainty principle, developed in quantum mechanics, states that certain pairs of physical properties cannot be simultaneously known to arbitrarily high precision. That is, the more precisely one property is measured, the less precisely the other can be measured. So for a more precise change in x, there tends to be a corresponding change in p such that the end result (product of the two elements) is still larger than a specific constant (h/2).

I actually first learnt of this principle not from a math class, but from a wine maker!

Consider wine making. Even  if the soil and grapes were top rate (well controlled), there is always another element, say weather, that creates uncertainty in the final wine quality.

The parallel to endurance sports is obvious.

Upon reflection, this principle induces a particular sense of perspective and humility.
