He was either subconsciously recalling something from a class from decades ago or he invented this from scratch (which would actually be remarkable in itself). His offense is that he didn't name it and give calculus its due. This is offensive to most Slashdotters.

I might be too late with my comment considering that the earth is cooling now, and perhaps not as hot as once though, but I think I have a solution:
