...ps the way I read the 'Calculus controversy', Newton sent his ideas to Collins, who showed the ideas to Leibniz. Suddenly Leibniz had the same idea. Leibniz was accused of plagiarising other works, not just Newtons, and was eventually found guilty.
That's according to the book I've read - there appear to be many books on the subject and it was a very long time ago, so who knows what really happened and does it really matter any more?
