29. Halley, Edmond (1656-1742) Tabulae astronomicae. Londini : Apud Gulielmum Innys, 1749. Edmond Halley of Halley's Comet fame became Astronomer Royal in 1719. An admirer of Newton he was instrumental in getting the Principia into print. These posthumously published tables are important for the manner in which they employed Newton's rules for calculating the position of the moon and Flamsteed's planetary observations. The planetary tables continued to be in use until the 1790s. This particular table shows conjuctions between the moon with the sun for the period in question. http://www.library.usyd.e du.au/libraries/rare/mode rnity/index.html

30. Harry Kroto 2004 F is the magnitude of the gravitational force between the two point masses, G is the gravitational constant,gravitational constant m1 is the mass of the first point mass, m2 is the mass of the second point mass, and r is the distance between the two point masses.
