Why Computers are Bad at Algebra
• Why Computers are Bad ...
Why is there a hexagonal structure in honeycombs? Why not squares? Or asymmetrical blobby shapes? In 36 B.C., the Roman scholar Marcus Terentius Varro wrote about two of the leading theories of the day. First: bees have six legs, so they must obviously prefer six-sided shapes. But that charming piece of numerology did not fool the geometers of day. They provided a second theory: Hexagons are the most efficient shape. Bees use wax to build the honeycombs -- and producing that wax expends bee energy. The ideal honeycomb structure is one that minimizes the amount of wax needed, while maximizing storage -- and the hexagonal structure does this best.

If you could have a bee the size of five years, you would feel a sting for five years and however long it would take such a sting to heal. Sounds like you need to get the Doctor.

    If you want to know what it would be like to be stung by a 4d bee, the fact is you would seem flat to it, so it could sting you from the inside without actually going through the outside of you! In other words, it could sting your heart, for example lol. Consider a two dimensional object (like a flat coin) being stung by an object in 3d space. You can get to the middle without penetrating the edges.

    I kinda always thought bees made hexagons because if you put circles (holes) as closely as possible, each circle is surrounded by 6 other circles, and the connections between them are inconsistent, and waste space, therefore, to un-waste as much space, you thin out the edges on all sides to the minimum, thus creating a hexagon

    How do honeybees know to make hexagons? According to the linked video, bees simply make circular honeycombs but as the wax hardens the surface tension molds/pulls the circles into hexagons. I may be spoiling it for some, but I don't like it when I'm forced to go watch another video when it takes 7 seconds to tell me the answer. So, I'm helping others like me.

    Bees make circular honeycombs. Those circles melt and expand into hexagons due to physics. Just like bubbles on a surface would be circular, but would become hexagons should there be at least 6 bubbles to surround another bubble. It is just the most stable structure for adjacent circles.

    In a regular sphere packing structure each sphere will touch 12 spheres around it. The 12 spheres will form the shape of a cuboctahedron. When compressing the structure, each of the 12 'touching' points on the surface of each sphere will become a face / plane, and eventually those faces will touch each other with their edges and fill up all the space. When points of a shape become faces (by truncating) the resulting figure is the dual of the original figure. The dual of the cuboctahedron is the rhombic dodecahedron. So, in my opinion, when compressing a sphere packing structure you will get a space filling structure made of rhombic dodecahedra (that have 12 regular sides), and not truncated octahedra. Packing of truncated octahedra and the Weaire Phelan shapes do of course exist, and they might be more efficient (less surface area), but the regular rhombic dodecahedra structure is what you get if you equally compress (or expand) spheres that are regularly and closely packed. So I think this is what 4D bees would come up with. Besides that the rhombic dodecahedra structure will also be stronger than the other packing structures, and strength is another important property of a beehive. scholar.harvard.edu/files/sbabaee/files/1-s2.0-s1359645412000900-main_0.pdf

    Another way to approach it, and the companion video came very close, but never quite explained this way, is to just take the ideal circular (or spherical for 4D bees) packing order and expand the shapes outward until the spaces are gone, creating flat surfaces where the shapes overlap. I also was reminded of spreading centers in plate tectonics. They're almost always relatively straight segments connecting 120 degree junctions. Some are triple junctions, but in reality, they're all triple junctions; the ones with just two segments had a failed third section, called an aulacogen.

    You don't have this quite right. I remember writing a paper on this in one of my undergrad classes in architecture school. A lot of fun figuring it out. Bees aren't intentionally making extruded hexagons, they'd be perfectly content making sloppy extruded circles, for example--it's the adjacent bees tunneling away and the counterpressures involved that create a hexlike honeycomb. Look for example at the shapes other than hexes bees produce when they aren't adjacent to other bees--you guys should really look at actual honeycombs, in the wild. We built fabric structures out of the shapes suggested by soap bubbles, too, understanding minimal surface area and the like. It's a great project for kids. Mix soap liquid with a plasticizer and the soap shapes "set" very quickly, making it possible to study these shapes at length. You can generate very different shapes by using differently shaped wire loops that in turn generate all manner of saddles, for example.

    Heh, it's interesting that when thinking about honeycombs, I have always assumed that the bees would have started by making circular or even spherical pockets, and then the natural optimization of trying to fit more stuff into the same space, would have pushed those pockets together, reducing the "dead space" and progressively getting more hexagon-like.

    If you actually look at honeycomb, the cells are essentially circular. The walls between them are a hexagonal grid because the wax itself packs together that way. The bees build circles, not hexagons - the hexagons are an emergent property of the comb due to the existence of many circles close together. The cells along the edge of a foundationless piece of comb aren't even particularly round.

    What about the Rhombic Dodecahedron? 11 years ago I began asking myself the same question: "The square is to the cube, as the hexagon is to the ____?" and the answer I came to was the Rhombic Dodecahedron. I'm surprised that it wasn't talked about in this video. It has the same length of edge for every edge, and every face is the same as well. It uniformly fills 3d space. It has a hexagonal lattice arrangement in one direction, and it has a checkerboard lattice structure in another direction. It looks like a cube when viewed from one direction, and it looks like a hexagon from another. It's a neat structure. If I were to make a modern version of minecraft, I would use the Rhombic Dodecahedron as my building block.

    Quick proof that hexagon is the most optimal shape. First we need (or at least I needed to), find an expression to represent the area of the equailaterial triangle. We know the area of the triangle is b*h/2, so we need to find the height. So we construct a right triangle inside the equilaterial triangle by bisecting a line. By the Pythagorean Theorem (a/2)^2 + h^2 = a^2, so c^2 = 3a^2/4 or h= sqrt(3)a/2, so the general expression is a * sqrt(3)a/2*1/2 = sqrt(3)a^2/4. The hexagon formula is likewise obtained by multiplying this formula by six, as a regular hexagon is just six combined regular triangles. For a given a perimeter, say K. The individual length of side of triangle tile is K/3. Using our formula we get sqrt(3)/36 * K^2 or about .048k^2 For squares we use K/4, so the area is simply K^2/16 or .0625K^2 For Hexagons we get 6*sqrt(3)*(K/2)^2/4 = 3sqrt(3)/72 * K^2 or about .072K^2, Therefore for a given non-Zero perimeter K, a Hexagon maximizes the area.

    +Jonathan A You did what she asked for, you proved that of a triangle, square and hexagon with the same perimeter, the hexagon has more area. What she did not expressly request, but could be inferred, is a proof that of all shapes that can tile the plane, the hexagon is most efficient. If you limit the question to regular polygons, you proved that as well, because of the regular polygons, only triangles, squares and hexagons tile the plane. A circle of circumference K has an area of k^2/(4*pi), about .0796K^2. The area of a regular octagon will be between that and .072K^2. A regular octagon will not tile the plane, but irregular ones will. Any irregular polygon of perimeter K will have an area less than a regular polygon of the same type. The question is, is there an irregular polygon that will tile the plane and whose area is greater than .072K^2?

    Did anyone else first come up with the solution of the pentagonal dodecahedron honeycomb? It seemed to be the intuitive thing to me as the hexagonal pattern arises from projecting tangent lines from the contact points of close-packed circles, so you could just do the same with tangent planes on close packed spheres. It at least gets you close to the most efficient answer, plus it keeps all the surfaces and edges flat.

    To roughly answer 1:37 (correct me if I'm wrong) A: area P: perimeter s: side length (note regular polygons have equal side length) n: number of sides The area of a regular polygon is given by the following formula (which I leave out the proof of; something something margin something): A = ( n * s^2 ) / ( 4 * tan(pi/n) ) The perimeter of a regular polygon is simply: P = n*s To rewrite the side length in terms of perimeter, we have: s = P / n Substituting out side-length in the above area equation gives: A = (P^2 / n) / ( 4 * tan(pi/n) )= P^2 / ( 4n * tan(pi/n) ) We do this because side length varies depending on the perimeter, which is held constant. We want to maximize the area-to-perimeter ratio (A / P): A / P = P / (4n * tan(pi/n)) Now we have an equation for the area-perimeter ratio in terms of the perimeter and the number of sides. At this point, we can plug in 3, 4, and 6 for the number of sides (n) to see that 6 has the maximum area-to-perimeter ratio for these three regular polygons which can tile the plane. What's interesting to note is that n*tan(pi/n), for n>=3 (as in the case of regular polygons) decreases (monotone) as n increases, so A / P increases as n increases. Of course, our intuition tells us that at eventually this area-to-perimeter ratio reaches a maximum. This is because n*tan(pi/n), while decreasing, is bounded below, and actually approaches pi. Thus, the upper bound for an area-to-perimeter ratio (in terms of perimeter) is P / (4 * pi). Of course, this is achieved for a circle, with: A = pi * r^2 P = 2 * pi * r To see these agree: (using known formula): A / P = r / 2 (using our upper bound): A / P = P / (4 * pi) = 2 * pi * r / (4 * pi) = r / 2

    Bees do not make hexagonal honeycomb cells. They make round ones! The wax then gets soft and the walls of the circular cells get pushed outward by their contents. This is what forms the hexagonal pattern, much the way groups of soap bubbles will form hexagons.
