What Is a Dimension? The Answer Will Bend Your Mind

  • Caltech physicist Sean Carroll explains dimensions in ways that even a 5-year-old can understand.
  • Written by a grade-school teacher in 1884, it’s a novel narrated by a square who lives in a two-dimensional world called Flatland populated by lines and shapes.
  • Flatland is a great way to introduce kids to the concept of dimensions, a technical concept in physics and mathematics that defies our everyday notion of physical space.
  • Indeed, the novel is arguably one of the best introductions to this heady subject short of having Sean Carroll, a physicist at the California Institute of Technology, explain dimensions to you himself.
  • Learn why Sean Carroll thinks we all live on multiple worlds.
  • Carroll starts by introducing the concept of multiple dimensions to a nine-year-old with Tinkertoys and builds upon these simple concepts until you’re convinced you might be able to build an inter-dimensional wormhole if you really wanted to.
