How Newtonian Physics Shaped the American Republic and Its Flag

A Smithsonian magazine article by Jo Marchant argues that Isaac Newton's physics profoundly influenced the American Revolution and the design of the U.S. government. Thomas Paine's 1776 pamphlet 'Common Sense' used Newtonian imagery, describing America as its own gravitational center rather than a satellite of England. An anonymous 1776 response in the Pennsylvania Ledger imagined a cosmos of equal stars, the first known expression of the U.S. as a constellation of equal stars. The founders, including John Adams, Thomas Jefferson, and Benjamin Franklin, were steeped in Newtonian thought. The separation of powers and federal system were inspired by Newton's laws of motion and gravity. The U.S. flag, with its stars on a blue field, was the first national flag to use cosmic imagery. The article traces the history of celestial symbolism in politics from ancient Egypt to the Enlightenment, and notes that today's scientific worldview has moved beyond Newtonian certainties.
