1. The Aztecs found Tenochtitlan on an island in a lake 1325

   Legend says they built where an eagle perched on a cactus eating a snake — the image now at the center of Mexico's flag. Mexico City stands on the drained lakebed.

2. Constantinople falls to the Ottoman army of Mehmed the Conqueror 1453

   The Ottomans breached walls that had stood for a thousand years using enormous cannons — built by Orban, a Hungarian engineer who had first offered his services to the Byzantines.

3. Alexander Fleming discovers penicillin in a moldy petri dish 1928

   Fleming found the mold after returning from holiday to his messy lab. He later said he hadn't planned to revolutionize medicine — 'but I suppose that was exactly what I did.'

4. Disneyland opens its gates in Anaheim, California 1955

   Opening day was a fiasco insiders called 'Black Sunday': heat melted the fresh asphalt, fountains failed, and thousands entered with counterfeit tickets.

5. Steve Jobs unveils the first iPhone 2007

   The demo units were so buggy that engineers mapped a single 'golden path' of actions for Jobs to follow on stage — deviating risked a crash.

6. The Philae probe makes the first-ever landing on a comet 2014

   Philae's harpoons failed and it bounced twice — the first bounce lasted nearly two hours in the comet's feeble gravity before it settled in a shadowy crevice.
