Isaac Newton (1643-1727) and Copernicus (1473-1543) were added for the definitives issue, which included three air mail stamps. Isaac Newton is best know for his theory about the law of gravity, but his “Principia Mathematica” (1686) with its three laws of motion greatly influenced thinking in Europe. Considered the father of modern astronomy, Nicolaus Copernicus was the first modern European scientist to propose that Earth and other planets revolve around the sun.
