The OCW materials she found for “Course 6.825 – Techniques in Artificial Intelligence” were just what she was looking for, and she quickly adapted several PowerPoint presentations and lectures to fit her syllabus. To her surprise, however the materials didn't just improve the content of her lectures; they also allowed her to cover more material in the same number of classes. “I used to spend a lot of class time drawing pictures on the board,” Thiagarajan said. “In data structures, for example, I need to show a lot of pictures of data trees and structures, and I had to draw all of them. Here, with the click of a button, I can show them something which has been very neatly and very beautifully done.”

I've added the ability to have more complex data structures here. But I dropped a hint in the first lecture about what you could computer with things. In fact if you think for a second about that list, you could ask what can I compute with just that set of constructs?
