The outcome was the famous "Principia Mathematica", first published in 1687, in which Newton presented solutions to most of the problems of motion that had concerned earlier scientists. This was the high point of his professional life, though he continuously revised and improved the work until his death in 1727. The papers Newton left behind testify to the incredible powers of concentration of the genius who opened the door to the age of technology.
