Everyone knows the Nobel Peace Prize. This is for the person who contributed "the greatest benefit to humankind". Fewer people know about the Ig Nobel Prize. This is to "honor achievements that first make people laugh, and then make them think". This year's Ig Nobel award for transportation is for an experiment on the effects on rhinoceroses of hanging them upside down. Researchers wanted to know the healthiest way to move rhinoceroses by helicopter.

Wikipedia says: "The Ig Nobel Prize is a satirical prize awarded…to celebrate ten unusual or trivial achievements in scientific research." It added: "The name of the award is a pun on the Nobel Prize." Other winners this year studied bacteria in chewing gum, cat communication, and whether humans grow beards to protect themselves from punches to the face. All winners win an old Zimbabwean $10 trillion note.
