By duration · Order from shortest to longest.

1. One swing of a grandfather clock's pendulum 1 sec

   A pendulum about one metre long swings in almost exactly one second — a coincidence so neat it was once proposed as the definition of the metre.

2. a-ha's 'Take On Me' 3.8 min

   The Norwegian band recorded it three times before it became a hit — the famous pencil-sketch video took 16 weeks of rotoscoping by hand.

3. A main-stage TED talk at its maximum allowed length 18 min

   TED's curator calls it 'long enough to be serious, short enough to hold attention' — even Bill Gates and presidents get cut off at the limit.

4. Munich's Oktoberfest 17 days

   Despite the name, most of it happens in September — and visitors drink roughly six to seven million litres of beer before it ends.

5. The first circumnavigation of the globe (Magellan's expedition) 3 years

   Magellan himself never made it — he was killed in the Philippines. Just 18 of the original ~270 crew limped home aboard one remaining ship.

6. Voyager 1's journey from launch to interstellar space 35 years

   It carries a golden record with greetings in 55 languages and Chuck Berry — and it still phones home daily on a 1970s 8-track-era computer.
