1. Hannibal marches his army and war elephants across the Alps 218 BCE

   He set out with around 37 elephants; nearly all died in the crossing or soon after, yet he rampaged through Italy for fifteen years.

2. Martin Luther publishes his Ninety-Five Theses, sparking the Reformation 1517

   Thanks to the new printing press, the theses spread across Germany in about two weeks — arguably history's first viral document.

3. James Watt patents his improved steam engine 1769

   Watt also coined 'horsepower' as a marketing tool — comparing his engines to the draft horses customers would be replacing. The watt unit is named for him.

4. Alexander Graham Bell patents the telephone 1876

   Bell's lawyer filed at the patent office mere hours before rival Elisha Gray filed a notice for a similar device — one of history's closest patent races.

5. 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.'

6. The Human Genome Project is declared complete 2003

   The 'complete' genome actually covered about 92% — the trickiest gaps weren't fully sequenced until nearly two decades later.
