Got history? Not so much? I know, you probably have PTHD, Post Traumatic History Disorder. Many of us suffer from this due to the horrifyingly torturously dull teaching techniques. We suffered through in school. This will not be a bad thing, quite the opposite, it’s a fascinating discussion about Leonardo da Vinci, artist, sculptor, engineer, architect, anatomist, mathematician, all around cool guy. You can thank me later, enjoy!
