    Newton's law of universal gravitation states that a particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.[note 1] This is a general physical law derived from empirical observations by what Isaac Newton called induction.[1] It is a part of classical mechanics and was formulated in Newton's work Philosophiæ Naturalis Principia Mathematica ("the Principia"), first published on 5 July 1687. (When Newton's book was presented in 1686 to the Royal Society, Robert Hooke made a claim that Newton had obtained the inverse square law from him; see the History section below.)

    I did not realise that a sense of humour was not a prerequisite for this forum!

    it's the 200 year error in the date that upsets me.



    but as any reader of the Hitch Hiker's Guide to the Galaxy knows, people can still fly -- the tricky bit is mastering the art of missing the ground

    Just takes a gentle swoop.......and something very interesting to distract you from hitting the ground at just the right moment......

    Am I the only person who still misses Douglas Adams terribly, not to mention (Sir) Terry Pratchett??
