Isaac Newton's Universal Law of Gravitation
Isaac Newton's Second Law of Motion
Isaac Newton's Third Law of Motion
These stamps are based on Isaac Newton's great scientific contributions, the Universal Law of Gravitation and his Three Laws of Motion, important and highly used physic theories. The stamps represent scientific diagrams and show the equations that makes up the theories. These stamps are part of my RSA competition entry, which was based on British firsts, and what better of a subject than Isaac Newton.
