I work across mathematics, physics, astronomy and optics. My Principia states the laws of motion and universal gravitation, I built calculus, and I showed that white light is a spectrum of colours.
I treat the heavens, a falling body and a beam of light as one research problem, solved with the same mathematics and the same experimental discipline.
The Scientific Revolution: a world still argued from Aristotle, where I worked from Cambridge and later London to make natural science quantitative and testable.
The shape of this portfolio — taller means stronger evidence in that mode.
