At this time of year, everyone is running around trying to find the right gift. Here’s mine to you. Maria Kalman and the Internet. All I know is: no one shall want to return it. Pass the link on. My thanks to “Brain Pickings”, another wondrous link btw (and recently discussed in NYTimes) for posting the link to this video. I was first introduced to Maria Kalman several years ago through a monthly illustrated column in the New York Times called “The Principles of Uncertainty”.
