Hooke and Newton's rivalry began in 1672 when Newton presented his first paper on optics to the Royal Society. In his paper, he argued that light was composed of particles and white light was made of seven colours of the light spectrum. Many of the society's fellows, including Hooke, disagreed with this theory.
