# Formulae Collections

## Scientific and technical formulas.

Collections of - in this case scientific - formulas, usually to defined topics, such as chemistry, physics, mathematics. The corresponding collection lists formulas, rules and methods on the subject, but usually without further explanation.

A formula in this context represents a mathematical or physical relationship, usually in the form of an equation. To differentiate is the chemical formula that, depending on the type, showing the composition and optionally structural features of a chemical compound.

Below is a list of online available scientific formulas, rules and methods with a focus on chemistry and physics.
