Coins from antiquity:
The ancient science of chance
TEDx Penn 2022
Probability weaves an intricate thread through life, never more tragically visible than in times of catastrophe like wars, hurricanes, financial collapses, and pandemics. An accidental discovery in the mathematical theory of chance dating to the immediate aftermath of the French Revolution remarkably provides a skein connecting all these apparently disparate, chance-driven events, and provides a startling clarity of vision. In this talk I explore the ramifications of this discovery in realms apparently far apart, starting from the sad story of a birthday cake and proceeding to a once-in-a-century pandemic which has changed the lives of all the world's inhabitants — with a detour through mishaps in trials by jury and a side-helping of war and devastation — and discover an elegant commonality and simplicity of understanding of the progress of these complex events. This talk was given at a TEDx event using the TED conference format.
A rich and sumptuous book, a quarter-century in the making, which tackles the foundations of the mathematical theory of probability in a vibrant historical tapestry, made lush by riotous application, ancient and modern.
On-line video lectures
The video snippet below is the introductory video lecture in a suite of videos which invites the curious viewer into the magical world of probability. These video lectures originally appeared as a top-rated MOOC on Coursera in 2015. In total these lectures cover material equivalent to a semester course on undergraduate probability at the University of Pennsylvania where this academic has taught since 1986. Follow the link to the Video Lectures page for the full collection of video lectures.
This is a long page and, depending on the viewer's internet speed, may take a browser a short while to load the video thumbnails. Video playback should be delay-free from that point on.
The Courses page contains ancillary information to go with the video lectures: in the Probability folder viewers will find a summary of what they can expect to see as they wind their way through the suite of video lectures and what they can hope to learn, supporting documents, problem sets, and solutions.
