Mike Vecchione: Private Detective School

I went online to become a private detective. It was a private detective school online, and I paid online. But then I never heard from them again. I thought to myself, I either got ripped off or this is my first case.

Georg Cantor

Born 3 Mar 1845; died 6 Jan 1918 at age 72. Georg (Ferdinand Ludwig Philipp) Cantor was a Russian-German mathematician who created modern set theory and extended it to give the concept of transfinite numbers,with cardinal and ordinal number classes. Although Cantor's earliest work was concerned with Fourier series, his reputation rests upon his contribution to transfinite set theory. He began with the definition of infinite sets proposed by Dedekind in 1872: a set is infinite when it is similar to a proper part of itself. Sets with this property, such as the set of natural numbers are said to be 'denumerable' or 'countable'. His career was repeatedly interrupted after 1884 by mental illness. He died of heart failure in 1918 in a mental institution.
