Once upon a time, *calculator *and *computer* were job titles: you could earn a living if you knew how to find or . Today, these tasks can be performed by cell phone apps or the navigation bar of your web browser, and with only a little searching, you can answer the question “Write the equation of the line tangent to the graph of at “–even if you have no idea what a tangent line, graph, or at (2, 4) even means!

Some people look upon this with dismay: What happens if the internet goes down and you need to find without a calculator? The truth is…if the internet ever goes down, we’ll have *much* more pressing problems than an inability to find without a calculator.

It’s better to look on this as an opportunity: for the first time in human history, we can teach *mathematics*. So join me on a journey to discover mathematics. All you’ll need is a willingness to play around with ideas and see where they take you.
