A physicist may be described
(to first approximation)
As a simple prolate spheroid
Of infectious obfuscation.
Attempts to oversimplify
Reveal their odd propensity
To speak of spheroid cattle
Which are uniform in density—
Their perfect planes are frictionless;
Collisions are elastic;
They’re rarely seen acknowledging
The random or stochastic.
The chaos of the world outside
May leave them full of fears;
Such terra incognita
Might be filled with… Engineers!
(Of course, in XKCD, physicists are not prolate spheroids, but lines and circles, in two dimensions. Even easier!)
