0:00.0 | You know, hexagons are the bestogons. Why? Because bees. Bees are the best and build only the bestagon the hexagon. |
0:09.2 | Now, I know what you're thinking. Bees build hexagons because they're hexapods with hexagon eyes. |
0:14.0 | How could they do otherwise? Excellent point. But the Humble Bumble has an engineering problem to solve. |
0:19.7 | She makes two things. Honey and |
0:21.7 | wax, the former to eat and the latter to contain the former. To make but a little honey, |
0:26.5 | she must visit a lot of flowers, and to make one unit of wax, she needs eight units of honey. |
0:31.8 | Wax is costly for bees in flower terms, and honey is drippy in food terms. So to make a hive |
0:36.6 | that contains the maximum honey while using the minimum wax is royally vital. |
0:41.3 | Thus, a honeycomb conjecture, which shape works best. |
0:44.3 | To answer, we need to talk tiles. |
0:46.3 | Tiling is covering a surface with a pattern of polygons. There's lots of options because there's lots of polygons. |
0:52.3 | Even the regulars go on and on a gone. |
0:54.6 | Now for bees picking patterns, the more complicated ones obviously use more lines than necessary. |
0:59.7 | That's what complicated means, and thus a honeycomb of that tile would use more wax per honey. |
1:04.8 | So sticking to the simple regulars, there are just three that tile tightly, triangle |
1:08.7 | square and hexagon. Pentagons are broken hexagons, leaving gaps, same with septagons. |
1:12.6 | Octagons are all right, but there are no hexagon, which leaves the tiling trio which tile differently. |
1:18.6 | A square is a square of squares, which is a square of squares and so on. |
1:21.6 | Squares tile tightly by basically cheating, covering an infinite plane with an infinite number of parallel lines. |
1:27.9 | Like, wow, that's what a plane is. Boring! |
1:31.7 | Triangles pull the same trick, dividing themselves down into infinite nothing. |
1:35.5 | But not the hexagon, the only regular polygon to tile a plane without resorting to debasing self-division. |
