Coffee & Donuts, a topological DoubleQuote

[ by Charles Cameron — sadly, now dunkin’ diabetes ]

Some might claim that Dunkin is the link between Coffee and Donuts — it’s certainly a link I’ve appreciated myself on more than one occasion. Here’s another, and arguably more subtle linkage — topology.

In verbal format, it’s a mathematician’s inside joke:

The joke goes about topologists is that they can’t tell the difference between a coffee mug and a doughnut. For those who are not familiar with topology, topology is the study of geometrical objects where you don’t care about lengths and you don’t care about angles, what matters is how the spatial relations relate to each other.

Even better, here’s the same joke, illustrated — or refuted, if you prefer — in video by a master maker:

The only problem here — it’ll all prove a little pointless if you dunk your donut into the coffee cup without first supplying some coffee..

But morphing! What an ingenious way to provide and prove a DoubleQuote!
