Abstract: 1- Equations, Units and Dimensions
2- The Fundamentals: Mass, Length and Time. (and the Derived: all the others.)
3- Some Anomalies: Fractional Exponents? Different things with the Same Dimensions? The same things with Different Dimensions?
4- Add Charge, Temperature and Angle to the Fundamentals to resolve the anomalies (But the units are arbitrary and not explainable to Aliens.)
5- Change the Fundamentals to Angle, Charge, Mass, Velocity, Action, and Entropy, and make a unit system that Everyone can understand. (even Bug Eyed Monsters and Little Green Men all over the Universe)
6- Another way to look at the Heisenberg Uncertainty Principle.
