[playful instrumental synth music fades slowly]
You know...
00:00:00
You know...
00:00:00
Hexagons are the bestagons.
00:00:03
Why?
00:00:04
Because bees.
00:00:05
Bees are the best
00:00:06
and build only the bestagon, the hexagon.
00:00:09
Now, I know what you’re thinking.
00:00:10
Bees build hexagons because they're hexapods
00:00:12
with hexagon eyes.
00:00:14
How could they do otherwise?
00:00:15
Excellent point.
00:00:16
But the humble bumble has an engineering problem to solve.
00:00:19
She makes two things: honey and wax.
00:00:22
The former to eat,
00:00:23
and the latter to contain the former.
00:00:25
To make but a little honey,
00:00:26
she must visit a lot of flowers.
00:00:28
And to make one unit of wax,
00:00:30
she needs eight units of honey.
00:00:31
Wax is costly for bees in flower terms,
00:00:33
and honey is drippy in food terms,
00:00:35
so to make a hive that contains the maximum honey
00:00:38
while using the minimum wax is royally vital.
00:00:41
Thus, a honeycomb conjecture.
00:00:43
Which shape works best?
00:00:44
To answer, we need to talk tiles.
00:00:46
Tiling is covering a surface with a pattern of polygons.
00:00:49
There's lots of options
00:00:50
because there's lots of polygons.
00:00:52
Even the regulars go on and on-agon.
00:00:54
Now for bees picking patterns,
00:00:55
the more complicated ones
00:00:57
obviously use more lines than necessary.
00:00:59
That’s what complicated means.
00:01:01
And thus a honeycomb of that tile
00:01:02
would use more wax per honey.
00:01:04
So sticking to the simple regulars,
00:01:06
there are just three that tile tightly.
00:01:08
Triangle, square, and hexagon.
00:01:09
Pentagons are broken hexagons leaving gaps.
00:01:12
Same with septagons.
00:01:13
Octagons are alright,
00:01:14
but they're no hexagon.
00:01:15
Which leaves the tiling trio which tile differently.
00:01:18
A square is a square of squares,
00:01:20
which is a square of squares, and so on.
00:01:22
Squares tile tidily by basically cheating.
00:01:24
Covering an infinite plane with an
00:01:26
infinite number of parallel lines.
00:01:28
Like, wow, that's what a plane is.
00:01:30
Boring!
00:01:31
Triangles pull the same trick,
00:01:33
dividing themselves down into infinite nothing.
00:01:35
But not the hexagon!
00:01:37
The only regular polygon
00:01:38
to tile a plane without resorting to debasing self-division,
00:01:42
unlike some squares I could mention.
00:01:43
At least triangle is trying to be
00:01:45
more geometrically interesting than square,
00:01:47
teaming up a bit to…
00:01:48
one, two, three, four, five, six.
00:01:49
Wait, hexagon!
00:01:50
The other shapes can't help it.
00:01:52
They just want to be the bestagon.
00:01:54
Even some of the irregulars,
00:01:55
like rhombus, tile by hexagoning.
00:01:57
Same with your triakis tilis,
00:01:58
[with difficulty]
and deltoidal trihexagonals,
00:02:01
[with continued difficulty]
and your, ah, kisrhombille,
00:02:03
[with laughter]
and floret pentagonals.
00:02:06
Look, they're all just hexagons.
00:02:07
Even Cairo tiles
00:02:09
(poor pentagons)
00:02:10
tile up as best they can to form a lumpy hexagon.
00:02:13
The rest just can't compete with the best.
00:02:16
The hexagon,
00:02:16
nobly indivisible,
00:02:18
is the bestagon.
00:02:19
Uhh, where were we?
00:02:21
Oh right, honeycomb conjecture.
00:02:22
Max honey. Min wax. Three options.
00:02:24
Okay yes there's the circle.
00:02:26
A shape defined by the least perimeter for the most area,
00:02:29
but that only works when you need just one.
00:02:31
Pack circles and this is the best they can do.
00:02:33
Look at all that wasted space!
00:02:35
And even if you pack the gaps,
00:02:36
you still use more wax.
00:02:37
And, again, the way these circles,
00:02:39
arrange themselves …
00:02:40
it's almost like…
00:02:41
onetwothreefourfivesix
00:02:42
hidden hexagon!
00:02:42
Bees use the hexagon
00:02:44
because no shape is better to create
00:02:46
the maximum area for the minimum wall.
00:02:48
And this min-max stat of hexagon
00:02:50
is one of the many reason they show up everywhere.
00:02:53
Including in the aforementioned bee's eyes.
00:02:56
Each hexagon is a long tube that leads
00:02:58
to the light-catching cells at the bottom.
00:03:00
More light equals better vision and
00:03:02
hexagons let the most light in
00:03:04
using the least amount of wall.
00:03:06
So why aren't your eyes hexagons?
00:03:08
Au contraire mon ami,
00:03:09
they are l'Hexagone.
00:03:11
[intensely]
Not on the outside, but on the inside.
00:03:14
Your light-catching cells are at the back of your eye,
00:03:16
in a hexagonal grid for the same reason as bees.
00:03:19
Max light, min wall.
00:03:21
Your window to the world,
00:03:23
is but through the hexagon.
00:03:24
Does that not make it the bestagon?
00:03:26
Okay, maybe hexagon as min-max-agon
00:03:28
doesn't catch your fancy.
00:03:29
Then how about a little mystery, oui?
00:03:31
Let us travel to Saturn.
00:03:33
Yes, the rings are attention-grabbing,
00:03:35
but leave the equator,
00:03:36
travel north and here lies the unexplained.
00:03:39
The Great Hexagon of Saturn.
00:03:41
Need something for scale?
00:03:42
Well, here's the Earth.
00:03:43
Oh, here's six the Earths.
00:03:46
Saturn's hexagon is pretty big.
00:03:48
What is it?
00:03:49
Well, you might be thinking it's a geological formation.
00:03:52
An enormous basalt column
00:03:53
like the smaller versions you find on Earth.
00:03:56
But no.
00:03:56
Saturn is a gas giant.
00:03:58
There is no surface or geology to speak of.
00:04:00
So the great hexagon is composed of shapeless clouds
00:04:04
somehow keeping shape and changing color.
00:04:07
It's a magnificent solar system mystery.
00:04:09
And, while I'm no space archeologist,
00:04:11
if I was looking for an alien-gifted monolith,
00:04:14
on the most “look at me” planet,
00:04:16
under a hexagon beacon with earth-sized sides,
00:04:19
[tongue click]
that's where I would start.
00:04:21
After all, what aliens would want to make
00:04:23
first contact with the nearby monkeys
00:04:25
before they became enlightened
00:04:27
to pursue the universal truth.
00:04:29
Hexagon is the bestagon.
00:04:31
From the largest down to the smallest.
00:04:34
Say, for example, this tiny snowflake I happen to have,
00:04:37
that has six sides, as all snowflakes do.
00:04:40
Gee, what could cause that to be?
00:04:41
Let's zoom down to the atomic realm and see.
00:04:44
When water molecules join together to make a flake,
00:04:46
the sturdy shape they prefer is the hexagon.
00:04:49
As more molecules join,
00:04:50
they extend the flake fractally up.
00:04:52
The beauty of the snowflake on the monkey scale,
00:04:54
is but an extension of the hexagonal perfection
00:04:57
on the atomic scale.
00:04:58
Okay, yes*.*
00:04:59
You will sometimes find snowflakes with twelve sides,
00:05:02
but this happens when two growing snowflakes
00:05:03
get stuck together, so it still counts.
00:05:05
And the hexagon isn't just for snow,
00:05:07
but for all ice 1H,
00:05:09
which means basically all ice on earth.
00:05:11
Yeah, there's a little ice 1C
00:05:12
which we don't talk about
00:05:13
because it's made of cubes,
00:05:14
and cubes are boring.
00:05:16
And there's a bit of ice 9.
00:05:17
No, don't touch that.
00:05:18
But if there is ice in your drink,
00:05:19
give thanks to the hexagon for keeping it cool.
00:05:22
And it's not just water.
00:05:23
Lots of atoms use hexagons because…
00:05:25
(take a note)
00:05:26
hexagons are the bestagons.
00:05:28
Oh, using a pencil?
00:05:29
Get ready to have your mind blown
00:05:31
about the hexagon here too.
00:05:33
The lead.
00:05:34
Well, it isn't lead lead, it's carbon.
00:05:36
And you know what carbon atoms think is the bestagon?
00:05:38
[snap]
The hexagon.
00:05:40
Pencil graphite is a whole bunch of hexagonal carbons,
00:05:43
and when they happen to be in a straight sheet,
00:05:45
that's graphene,
00:05:46
which happens to be the strongest
00:05:48
atomic material in the universe.
00:05:50
Some of which is in that pencil.
00:05:52
To tear a sheet of graphene apart,
00:05:53
you would need a hundred times more force
00:05:56
than to do so with steel.
00:05:57
Hexagon is strong-a-gon.
00:05:59
This is because when hexagons come together,
00:06:01
they form three-sided joints 120 degrees apart.
00:06:04
This, for the least material,
00:06:06
is the most mechanically stable arrangement.
00:06:08
Pull on one joint,
00:06:09
and the other two equally pull back,
00:06:11
push in, and the other two are the
00:06:13
most able and stable to resist.
00:06:15
Now look anew at a tiling of hexagons
00:06:17
and you see it is composed of nothing
00:06:18
but these max stable joints,
00:06:20
each arranged perfectly to help the others
00:06:22
be stronger and stabler.
00:06:24
This is another reason hexagons show up everywhere.
00:06:27
The universe blesses stability in her physics,
00:06:30
from those basalt columns,
00:06:32
to bubbles which,
00:06:33
as soon as they can,
00:06:34
ditch their spheres to become
00:06:36
as close to hexagonal perfection as they can.
00:06:38
That's so cool.
00:06:39
Oh right, yes.
00:06:40
So if your pencil lead contains
00:06:42
some of the strongest material in the universe
00:06:44
how can you write with it?
00:06:45
Okay, okay.
00:06:46
This is going to get even more exciting.
00:06:49
While hexagons are super strong this way,
00:06:51
they aren't super strong this way.
00:06:53
On a small scale,
00:06:54
that means your pencil can break off
00:06:55
in layers to leave a mark.
00:06:57
But on a big scale,
00:06:58
hexagons can be flexible while keeping their strength,
00:07:01
letting us construct some totally unreal materials.
00:07:04
Print out a grid of hexagons in whatever,
00:07:06
from aluminum to cardboard,
00:07:07
make a little sandwich,
00:07:08
and pow!
00:07:09
You've got honeycomb paneling.
00:07:11
A ridonkulously tear-resistant material
00:07:13
that's also super light and flexible.
00:07:15
It's used everywhere
00:07:17
but particularly in aviation.
00:07:19
Rockets need to be strong yet light.
00:07:21
Same for aircraft.
00:07:22
With wings that really can't tear
00:07:24
but also need to bend.
00:07:25
And only the magic of the honeycomb panel
00:07:28
can do both as well.
00:07:29
Give thanks to the hexagon for blessing our flight.
00:07:32
And we still haven't yet discussed
00:07:34
the most important application of the hexagon.
00:07:36
Games!
00:07:37
For centuries there has been great debate over boards,
00:07:40
squares or hexagons?
00:07:42
Spoiler... hexagons win.
00:07:44
Square boards are the first thing
00:07:45
an unenlightened species would think of.
00:07:47
They look sensible and are easy to implement,
00:07:50
but they are terrible,
00:07:51
ineffective boards that cause spatial suffering.
00:07:53
On a square board move horizontal
00:07:55
or vertical one space
00:07:56
and you've moved one space,
00:07:58
but move diagonal
00:07:59
and the distance is the square root of two spaces.
00:08:02
Gross.
00:08:03
Diagonals warp the distance pieces move.
00:08:05
Square boards look even and tidy,
00:08:07
but it's deceit.
00:08:08
Their diagonals corrupting the meaning of space and time,
00:08:12
and of course they must,
00:08:13
because a square only has four true neighbors.
00:08:16
Hexagons, however, have six
00:08:18
which is more than four,
00:08:19
which is better!
00:08:20
And the distance from one space to the next
00:08:22
is the same in every direction.
00:08:24
One space.
00:08:25
Just as it should be.
00:08:26
If you're a game based on squares,
00:08:28
I'm so sorry.
00:08:29
But there is hope.
00:08:30
With thought and effort,
00:08:31
you can hexagon yourself into a better place.
00:08:34
As we all should aspire to do,
00:08:36
spreading order and hexagonal enlightenment
00:08:39
for, hexagons are the bestagons.
00:08:41
And now that you agree, with your eyes will see
00:08:44
their six-sided perfection in all things.
00:08:46
And you will say to yourself,
00:08:48
as part of the order
00:08:49
hexagons are the bestagons.
00:08:56
Uhh, thanks for stopping by for communicator coffee.
00:09:02
Now, go. Share the enlightenment of the order with others.
