Back to school

A few weeks ago my colleague Elena introduced me to Coursera - online university courses, which are free and available to anyone who's interested in learning something new. The range of the universities providing these courses is broad, from Duke to University of California to Stanford to Johns Hopkins University, and many others. And the list of their courses is pretty impressive: a History of the World since 1300, or Introduction to Mathematical Thinking, or Learn to Program: The Fundamentals, or Design, or Think Again: How to Reason and Argue, to name a few.  The latter is the one my friend Ani, Elena and i are taking right now; and it's really cool - the video lectures, the exercises, the quizzes, reading material. You can do it in your free time, on a couch,  night or day, and literally become smarter - and entertained - for free. Try it out and let us know what you think
