Scuba Math

This is our section for all you math geeks, science geeks, and dive theory geeks out there. We are writing articles on diving theory and the mathematical calculations that produce various diving tables and standards used in recreational diving. If you love formulas and equations as much as you love diving, keep coming back to this section for more.
