An arduino is not in fact an exotic animal - it is a small computer that can be used to create just about any electronic application. If you've seen the now-famous 8x8x8 LED cube demo: http://www.youtube.com/watch?v=6mXM-oGggrM, you can program it with an arduino. You can build robots, light displays, music makers, and much much more using an arduino! In this class, we'll talk about how to set up a basic arduino environment to build a very simple application involving LEDs. If we have time, we'll dive into more advanced topics. Do not bring a computer to class; we will all be taking turns and programming together as a class using only one computer!

When I say "infinity" I only mean this: $$\infty$$, right? In this class we'll use symbols like these to describe infinity: $$\aleph_0$$, $$\bet_1$$, etc. We'll use basic set theory principles to build the natural numbers, then play with them in relation to the integers, rational numbers, and real numbers. We'll then relate numbers to infinity... Is the infinity that describes how many integers there are different than the infinity that describes how many real numbers there are? In this class, we'll talk about why the answer is yes. We will build up to infinity with literally no prerequisites...
