For reference, the equatorial circumference of the Earth is 40075 km, so 20037 km is the furthest apart two points on Earth can be.

(Sidenote: the longest distance from the Shetlands to Tristan da Cunha just barely edges out the longest distance from Grand Cayman to Dhekelia, that is, by about 60 km, so we will not have to also address British-Cypriot territorial disputes.)

The Four-Colorability of the World: Addendum on Planarity

After presenting my conclusions in my previous post on the four-colorability of the world to several friends and friends of friends, we pondered the question of whether the map of the world’s countries is planar. It is in fact not: consider the induced subgraph of (that is, consider the connections among) Turkey, Georgia, Armenia, Azerbaijan, Iran, Turkmenistan, Kazakhstan, and Russia.

Resistance

You were big
We were small
You had pride
We couldn’t
We were too insignificant
To even be noticeable
And thus you brushed us aside
Until you found the way
To remove us en masse
Your lives were long
Our lives were short
You made our lives shorter
And you were so proud of it

But we’re still here
And we’re waiting for you to
In your gloating
Overlook us
Because the undeniable is that
With our ephemerality
Change is on our side
At least more so than on yours
And together
We shall evolve
We shall struggle
And
We shall overcome
Your antibiotics
