The Si system of units are explained. This is the system that will be used everywhere in the resources of Proofs program

We briefly present Gaussian units and trace the source of appearance of velocity of light in Maxwell's equations.

Some Important Constants

Constants and Units

The numerical values of a few important constants are listed.

By means of a few examples we show how dimensional analysis can be used to quickly estimate numerical values of expressions occurring in problems
