"A fantastic and eclectic festival of science and arts in a long-overdue celebration of the life and achievements of one of the world’s greatest scientists, Sir Isaac Newton – courtesy of South Kesteven District Council."
"Yet Newton could not make the mechanical solution of Descartes work. The vortices simply could not reproduce the changes in speed of the planets as they approached the sun.
