The Nobel Prize may be the world’s most prestigious award, given annually to those who have “conferred the greatest benefit to humankind,” according to the Nobel Foundation, which administers the awards. There are actually five Nobel prizes, given in the fields of physics, chemistry, physiology or medicine, literature, and peace. An award for economics was added in 1968. Not as well known, and not as prestigious, is the Ig Nobel Prize, a satiric competition awarded annually since 1991 to celebrate 10 unusual or trivial achievements in scientific research. They are meant to reward research that makes people laugh, and then makes them think. See what you know about the Ig Nobel Prize.
