Newton responded with three letters, first answering the question briefly, and then offering more information as Pepys pressed for cla...

Isaac Newton and the astronomical refraction.

In a short interval toward the end of 1694, Isaac Newton developed two mathematical models for the theory of the astronomical refraction and calculated two refraction tables, but did not publish his theory. Much effort has been expended, starting with Biot in 1836, in the attempt to identify the methods and equations that Newton used. In contrast to previous work, a closed form solution is iden...
