The video, above, provides an overview of an online course, Calculus: Single Variable, via coursera from the University of Pennsylvania. This course provides a brisk, entertaining treatment of differential and integral calculus, with an emphasis on conceptual understanding and applications to the engineering, physical, and social sciences.
Robert Ghrist is the Andrea Mitchell University Professor of Mathematics and Electrical & Systems Engineering at the University of Pennsylvania. Coursera offers many courses in all sorts of disciplines including: Introduction to Genetics and Evolution (Duke), Scientific Computing (University of Washington), Principles of Economics for Scientists (California Institute of Technology), Game Theory (Stanford University and The University of British Columbia), A Beginner’s Guide to Irrational Behavior (Dan Ariely, Duke University), The Modern World: Global History since 1760 (University of Virginia), Microeconomics for Managers (University of California, Irvine), Data Analysis (Johns Hopkins University), Fundamentals of Human Nutrition (University of Florida), Algorithms, Part I (Princeton University), The Ancient Greeks (Wesleyan University), Astrobiology and the Search for Extraterrestrial Life (University of Edinburgh) and Epigenetic Control of Gene Expression, (University of Melbourne).
All the classes are free. These courses, and many more, are extremely appealing. I signed up for 2. I would be interested in signing up for much more but I worry about having the time to commit to keeping up with the coursework. I hope the first two go well and I can sign up for more in the future.
