Video of the Week: "Why do honeybees love hexagons?"

I love hexagons, and honeybees do too. It's so beautiful to me how they fit together (tesselate). They're aesthetically pleasing and efficient. Take a look: 

Here are a few things I'm wondering: 

  • Where else do you see these tessellating hexagons? 
  • Why are hexagons the most efficient use of space for the honeybees? 
  • What's behind this perfect shape choice? Is it chance? Evolution? God? 
  • What other shapes can tesselate?
