Boyle's Law

This stamp is part of a set of 10, released by the Royal Mail on 25 February 2010, to commemorate the Royal Society. Well, the long-haired guy on the stamp is Robert Boyle, who discovered Boyle's Law, which is so important to understand for scuba divers. This is the scientific phenomenon that requires us divers to wear weights and an inflatable device (the buoyancy jacket, mate), and for us not to hold our breath when using scuba equipment underwater.

Robert Boyle was also featured on an Irish stamp released in 1981.
