By Patrick Berger Investigation. Intrigue. Drama. Love. Think CSI style investigation. But instead of crime being the issue of inquiry – it’s history and math. Before you cringe, know that this is so much better than all those math problems you have to do in high school. It’s history you can witness (and guess what – history is all about sex) and math you can feast your eyes on. Prepare your mind for intellectual delights as well as entertaining encounters. Arcadia is all about how we make our mark on this world and how the world might interpret that mark in the future. Imagine how the world would view that doodle in your math notebook if it was all that was left of 2011… We are all making history, right now.
