My favourite on-line comic strip is becoming quite famous, not in the least because of the “What-If” series of far-out questions and answers. This one, I thought, would be of interest to readers of this blog, as it deals with buoyancy, especially negative buoyancy. Of interest is the rate at which a negatively buoyant object descends. Using the example of a bowling ball, which, being a much simpler shape than, say, a diver, is easier to predict, it relates descent rate to density. The relationship is non-linear, as doubling the density doesn’t double the descent rate.

At any rate some of you might find it interesting or at least discover an interesting new web comic.
