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. 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.

3. The first modern Olympic Games are held in Athens 1896

   Just 14 nations and 241 athletes competed — all men — and winners received silver medals, not gold.

4. 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.'

5. IBM's Deep Blue defeats world chess champion Garry Kasparov 1997

   Kasparov was reportedly unnerved by one inexplicable move — which some engineers later suggested may have been the result of a software bug.

6. DeepMind's AlphaGo defeats Go champion Lee Sedol 2016

   AlphaGo's 'Move 37' was so alien that commentators assumed it was a mistake. Lee won a single game back with a move fans dubbed 'God's touch.'
