Blockchain. Coinbase. Mining. You've heard all the bitcoin buzzwords -- but what do they actually mean? In this class, we'll survey the tumultuous history and bright potential of the first-ever cryptocurrency, bitcoin; dive into the technical underpinnings of bitcoin and its companion public ledger, the blockchain; and discuss how you -- yes, you -- can participate in this cashless and bankless revolution taking the worlds of finance and distributed computing by storm.

Having a worse quality of living. Suffering financial harm. Being manipulated and robbed of personal autonomy. Having your society collapse. Ending up falsely accused or imprisoned. Ending up dead. What do all of these things have in common? They are the potential costs, according to one source, of a poor comprehension of Bayes' Theorem. In this class, we'll teach an intuitive understanding of Bayes' Theorem and rational decision-making through real-world examples, and show how applying Bayes' Theorem in social situations can allay awkwardness, generate key inferences, and disrupt social hierarchies, allowing, in many cases, the question-asker to be empowered as the effective decision-maker.

What is electricity? How do batteries work? Heck, what is "energy" in the first place? How can a tiny magnet defeat the gravitational pull of the entire earth? And why don't the protons in an atom's nucleus repel each other like positive charges are supposed to? Come hear these questions -- and more -- answered in a lively crash-course on the fundamental forces of the universe. Best of all, you will get to build (and bring home!) your very own electromagnetic motor. I think we can all agree that this is an incredibly "attractive" class to attend.
