The Stanford Center for Professional Development has digitized more than one hundred tapes of Knuth's musings, lectures, and selected classes and posted them online. These archived tapes resonate with not only his thoughts, but with insights from students, audience members, and other luminaries in mathematics and computer science. They are available to the public free of charge. Knuth's impact is far-reaching. Literate programming, attributed to Knuth, essentially holds that computer programs should be developed with an eye toward human comprehension more than computer readability. He maintains that the very act of communicating one's work clearly to other people will improve the work itself.
