Dynamics and Masses of Astronomical Bodies
The motion of astronomical bodies was first correctly analyzed by Newton, in the second half of the 17th century. He saw that a variety of apparently unrelated observations all had common features and should form part of a single theory of gravitational interaction. To formulate the theory, he had to invent mathematical techniques that described the observations and showed their interrelationship. His struggles with the mathematical problems are recorded in his book Principia Mathematica (Ne00).
