By duration · Order from shortest to longest.

1. One full revolution of a helicopter's main rotor 150 ms

   Main rotors spin at only a few hundred rpm, but the blade tips travel so fast they approach the speed of sound — the source of that thudding chop.

2. The men's 100 m freestyle world record swim 46.4 sec

   Pan Zhanle's 46.40 at Paris 2024 stunned the field — he won by over a second, an eternity in a sprint event decided by fingernails.

3. A Formula 1 qualifying lap of Monaco 1.2 min

   Monaco is F1's slowest lap by average speed, yet drivers call it the hardest 78 corners-per-race of the year — the barriers forgive nothing.

4. The Epsom Derby, Britain's most famous horse race 2.5 min

   Workforce's 2010 record run covered the mile and a half at over 56 km/h — and the race has been run every year since 1780, even through both World Wars.

5. The Anglo-Zanzibar War of 1896 38 min

   History's shortest war: the Royal Navy shelled the palace at 9:02 am, the sultan fled to the German consulate, and it was all over before 10.

6. The Holy Roman Empire, from Otto the Great to its dissolution 844 years

   Voltaire quipped it was 'neither holy, nor Roman, nor an empire' — yet it lasted 844 years before Napoleon finished it off in 1806.
