The principle described by the physicist Albert Einstein's famous formula: E = mc^2, involves mass–energy equivalence. I.e. the relationship between mass and energy.

The earliest developed breathalyzer was based on reaction of alcohol if present in the exhaled air with a cocktail of chemicals containing sulfuric acid, potassium dichromate, silver nitrate, and water. Silver nitrate catalyzes the reaction between alcohol and potassium dichromate in acidic medium.
