Prince Charles outwitted by wily scientists

This week Charles has complained about the invention of the wheel:

We are constantly told that the wheel transformed human life for the better.Well, perhaps. But how much evidence do we have for this oft-repeated claim? There is a growing feeling among many alternative transport practitioners, that, far from liberating mankind, this much-vaunted triumph of human ingenuity actually condemned us to live the very busy, machine-driven existence which is now responsible for an explosion of allergies and other stress-related disorders.

But those clever scientists have already finessed his new moan, by inventing a bike with square wheels.
