“The picture itself is just the tip of the iceberg”*…

Your correspondent’s rendering of an iceberg

Icebergs are less dense than water, so they always float with about 10% of their mass above the water. But which way up? An iceberg wouldn’t float exactly like on this page in reality. Its three-dimensional distribution of mass and its relative density compared to the water are both significant factors that are only approximated here.

From Joshua Tauberer (@JoshData), a tool that will let you draw an iceberg and see how it will float: “Iceberger.”

For inspiration, see Frederic Edwin Church’s 19th century iceberg paintings.

As we seek balance, we might note that today is International Polar Bear Day. an event celebrated each year on this date to raise awareness about the conservation status of the polar bear.
