1/ Da Vinci's anatomical discoveries... • First to describe the heart as a 4-chambered muscle • Recognized coronary artery disease 150 years before physicians He once dissected 30+ cadavers to understand anatomy:

2/ The Last Supper was a math puzzle for future mathematicians. Da Vinci used perspective to draw focus to Christ: All lines in the painting converge at a single vanishing point behind Jesus' right temple. @Culture_Crit has a great post on this: https://x.com/Culture_Crit/sta...

3/ Da Vinci revolutionized painting techniques through chemistry: • Created custom pigments with 5% beeswax • Experimented with oil paints (new at the time) Mona Lisa's eyes was Da Vinci's signature painting technique, sfumato in action. Art and optics, perfectly merged.

4/ Da Vinci had a visionary engineer mind: • Designed a proto-helicopter ("Aerial Screw") • Invented the modern mitered canal lock • Sketched a parachute (successfully tested 500 YEARS later!) Da Vinci is left-handed and wrote backwards and can only be read in a mirror...

There're conspiracies on why behind Leo's writing, here're a few: 1. He was left-handed (prevented smudging) 2. Kept his discoveries secret 3. Just liked being different For me, it's probably all of the above.

5/ Da Vinci predicted Earthshine: He figured this out when most people didn't even know Earth orbited the sun. He described the faint glow on the dark part of a crescent moon a sunlight reflecting off Earth onto the moon.

6/ Da Vinci's legacy is filled with thousands of pages of unpublished notes. Some say his secrecy is a loss to humanity. Others think he was a master procrastinator. Walter Isaacson explains: ↓
