The Dialogues of Galileo Galilei with translator's notes by Stillman Drake, forward by Albert Einstein, and supplemental forward by James A. Green, with mathematical remarks on alternative modern formulations and solutions in the margins by James A. Green and illustrations from Galileo-related artwork and also from astrophotography. Galileo's famous treatise on mechanics and dynamics includes applications to cannonry, archery, and other topics germane not only to physics and astronomy, but also to warfare and engineering. The modern solutions to Galilean problems are often amusing and sometimes include the unexpected. Renaissance remarks such as "the moon is formed from a diaphanous substance" can now be illustrated from astrophotography in a way that is humorously clarifying.
