Five exhibits to begin with

Each one takes a few minutes. Guess before you look, then follow the arrow at the top of the page to the next one.

  1. 1 Scale · H007 How Big Is Africa... Really? Start with size: the map you grew up with shrinks Africa.
  2. 2 Perspective · H043 Is Reno, Nevada west of Los Angeles? Then direction: a city that "should" be east of Los Angeles isn't.
  3. 3 Probability · H005 How many people does it take before a shared birthday is more likely than not? Then chance: a coincidence that's far more likely than it feels.
  4. 4 Statistics · H054 Where should you armor the bomber — where the bullet holes are, or where they aren't? Then evidence: the data that's missing can matter most.
  5. 5 Systems · H079 Can a new road make traffic worse? Then systems: adding a road can make everyone slower.

After these, explore all 102 exhibits by theme.
