Isaac Newton has been credited with the first description of conformal interaction observed through the interference phenomenon known as Newton's rings, though it was S. D. Poisson in 1823 who first described the optical characteristics of two identical surfaces in contact.
In a large range of random graphs of order n and size M(n) the distribution of the number of tree components of order k is asymptotically Poisson.
