I knew it!  They’re clearly more intelligent than humans!

It turns out that dolphins use maths and physics to detect sardines in water that has lots of bubbles in it.  They use sonar clicks of varying amplitudes, amplify the responses differently, and do some maths to figure out where the fish are.

Clearly, it won’t be long before their mathematical ability surpasses that of most of the human race.  I have only one thing to say to that.

So long, and thanks for all the fish.
