In conclusion...

The Second Law of Thermodynamics: The entropy (disorder) of the universe increases in a spontaneous process and remains unchanged in an equilibrium process. In other words, disorder will tend to increase if things are left to themselves.

Heisenberg Uncertainty Principle: It is impossible to know simultaneously both the momentum (defined as mass times velocity) and the position of a particle with certainty. In other words, the more accurately you try to measure the position of the particle, the less accurately you can measure its speed. A fundamental, inescapable property of the world!
