One week after getting stalled talking about the number line and infinity, Zach and Rafe are back on track and finally get to what infinity really means.  The concept of one-to-one can be applied to the Natural Numbers to reveal the first level of infinity and Cantor's diagonalization argument is used to show that there are levels of infinity beyond the aleph-null, the cardinality of the natural numbers.

As is typical, this foray into some pretty heady mathematics is punctuated by spontaneous sidebars, including discussions of cave paintings, wrapping paper, Lemonheads candy, and much more.  Come for the math and stay for the fun, or do it the other way around; it's a fun romp up the number line literally to infinity and beyond.
