The last 350 pages of A New Kind of Science contain 1350 notes covering a wide range of issues. About 150 of those notes are primarily historical. Given here are a few such notes of particularly general interest.

Almost every note is based on extensive historical research and scholarship. At a future date, we may attempt to make available Dr. Wolfram's primary research materials. Scholars who wish to have further information now about specific points in the notes may contact us.
