Happy New Year. DTLR would like to point its readers to Richard Feynman's 1964 Messenger Lectures at Cornell University, which Bill Gates and Microsoft have made available for viewing
at Project Tuva. These lectures also appeared in book form (Feynman, 1967). DTLR highly recommends this lecture series.
