The internet is overflowing with new math discoveries. The difficulty is identifying them...and separating the wheat from the chaff!
Example One: Alexander Bogomolny's great webiste, Cut-the-Knot.org, has been suggested many times on MathNEXUS. A "new" post notes that "Harlan Brothers has recently discovered the fundamental constant e hidden in the Pascal Triangle; this by taking products - instead of sums - of all elements in a row." This caught my attention, as for most of my life I have been intrigued (and surprised) by everything that can be found in Pascal's Triangle....and this is a new twist, complete with a proof. Consider e in the Pascal Triangle
Example Two: The Guardian recently reported mathematician Edmund Harriss' discovery of a delightful fractal curve that no one had ever drawn before. Inspired by the golden ratio, it is both an interesting picture and a purveyor of some interesting theory that brings "the golden ratio into a family of perfect proportions." It is called The Harriss Spiral. A side aspect is the ratio 1.325, which determines the rectangle underlying the creation of the Harriss spiral....it is known as the “plastic number.”
