The Revenge of the Hidden Shallows

 
After giving a geology evening class in which I singularly failed to explain isotopes, radioactive decay, and the absolute dating of elements in rocks, I feel the need to republish the following text, originally published here on May 18th, 2009:

Hidden Shallows

Some people seem to be superficial, but turn out to have hidden depths. I am the reverse. People think I am clever, but my profundity is actually very limited. I possess numerous hidden shallows, upon which the galleons of intelligence and understanding regularly run aground. Luckily the organizations who fund my research have yet to conduct any detailed bathymetric studies.
