1. The Parthenon is completed atop the Acropolis in Athens 432 BCE

   It contains almost no perfectly straight lines: the columns bulge and the base curves slightly upward, optical tricks that make it look flawless.

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. Germany invades Poland, beginning the Second World War 1939

   Britain and France declared war two days later — then months of eerie quiet followed on the Western Front, a period nicknamed the 'Phoney War.'

4. The Beatles make their first appearance on The Ed Sullivan Show 1964

   An estimated 73 million Americans watched — roughly forty percent of the US population — launching the British Invasion overnight.

5. The Space Shuttle Columbia makes the first shuttle flight 1981

   It was the first time NASA launched humans on a vehicle that had never flown an uncrewed test — commander John Young had already walked on the Moon.
