Reading the Wall Street journal today, I marveled at the half page ad "Mastering Differential Equations - The Visual Method". A limited time offer 70% off if ordered by January 3. Regular price $254.95 now $69.95.
Well - I wonder how big the market is for this DVD series taught by Professor Robert L. Devaney (Boston University)?
"For centuries, differential equations have been the key to unlocking nature's deepest secrets. But now, with the aid of easy-to-grasp computer graphics, a highly visual method exists that can start a committed learner on the road to finally mastering this beautiful application of the ideas of calculus."
Wow - hold the door! Don't wait another second to get your copy ordered. Sure to be a best seller!
