Ireland 2012 350th Anniversary of the formulation of Boyle's Law.

The An Post of Ireland released a stamp on 5 July 2012 celebrating the 350th anniversary of the formulation of Boyle's Law, a law so very important to understand in scuba diving. The stamp shows a portrait of Robert Boyle (1627-1691) on the left, with his famous formula together with an illustrative graph on the right. Boyle’s Law, first published in 1662, states that for an enclosed volume of gas the pressure varies inversely with the volume while the temperature is kept constant.

Marshall Islands issued on 23 April 2012, a sheetlet of 16 45-cent stamps on the theme of Great Scientists of the World, and there we find Sir Robert Boyle (1627-1691) who gave us Boyle's Law that is so important for scuba divers.

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.
