Why not make an iceberg?


A post on Mathstodon made me aware there’s a bit of talk about iceberg shapes. Particularly that one of the iconic photographs of an iceberg above-and-below water, is a imaginative work. A real iceberg wouldn’t be stable in that orientation. Which, I’ll admit, isn’t something I had thought about. I also hadn’t thought about the photography challenge of getting a clear picture of something in sunlight and in water at once. There was a lot I hadn’t thought about. In my defense, I spend a lot of time noticing comic strips had a character complain about the New Math.

But this all leads me to a fun little play tool: Iceberger, designed to let you sketch in a potential iceberg and see what it does. Often, that’s roll over to a more stable orientation. It’s fun to play with, and to watch shapes tilt over, gradually or rapidly. And playing with it may help one develop a sense for what kinds of shapes should be stable in water, and what kinds should not.
