Laws Of Physics

1995: In “Tumbling toast, Murphy’s Law and the fundamental constants”, Robert A.J. Matthews demonstrated mathematically that “toast does indeed have an inherent tendency to land butter-side down”. At the end of his article, Matthews suggested ways to avoid this messy outcome: by swiping at the falling toast, to give it a horizontal as well as a vertical velocity; by reducing toast size to 2.5-centimetre squares; or by breakfasting at 3-metre-high tables.

Perpetual Motion Cat

1993: Cats always fall on their feet.

Toast always lands buttered side down.

So if a slice of buttered toast were strapped to a cat’s back and the cat dropped from height, would the cat land on its feet or on its buttered back?

John Frazee, who submitted this conundrum to the magazine Omni, suggested that the unfortunate feline would hover, spinning, just above the ground. The buttered cat would, in fact, be a perpetual motion device.
