Locked Out

Being the office supervisor, I had to have a word with a new employee who never arrived at work on time. I explained that her tardiness was unacceptable and that other employees had noticed that she was walking in late every day. After listening to my complaints, she agreed that this was a problem and even offered a solution.
"Is there another door I could use?"

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.
