Hard to believe there was a day that you had to pay cold hard cash to receive world class university instruction. Open courses I believe are responsible for the rate of innovation we see today in all areas of science and technology. You can really teach yourself anything these days if you can pay your Internet bill.
This was such a fantastic class. The best part was Charles Lieserson's Leiserchess engine and the diet Dr. Pepper he drank in every single lecture.
