It was #onthisday
in 1687 that Sir Isaac Newton first published his magnum opus: the Principia, one of the most important works in the #history
In the Principia, or the Philosophiæ Naturalis Principia Mathematica, Newton set out in mathematical terms the principles of force, time, and motion, and revolutionized methods of scientific investigation. At the time, many of his ideas were not readily accepted, and only years later would the scientific community begin to fully embrace Newton's work.
Over the centuries, Newton's ideas in the Principia have guided our development of modern physical science. His three laws of motion and explanations of #physics
continue to account for many of the observations scientists make in the world today. The influence of this work is seen in scientific fields and applications ranging from how we understand protein folding in biology to how we manage heat flow and shielding in #nulcear
