Arash, I am quite shocked by your reply http://imechanica.org/node/3045#comment-7151.  First you say "with all the due respect", then you say "trivial history".  But you prudently say "maybe I miss the point".  Maybe useful to clarify, also because probably iMechanica should start a discussion about history of mechanics starting a little earlier than this century. How can we judge Leonardo da Vinci? He has no published papers, no citation, no index, no Nobel prize... Not even a Timoshenko medal!  Maybe we should give him one post-mortem?    Please see the attachment.  Watch also the videos:

Anyone interested in the history of mechanical technology might find interesting the series that I have published in Mechanical Engineering magazine.
