This is pretty awesome. Andre Geim won the Nobel Prize in physics this year, for his work with graphene. Ten years ago, Geim won an IgNobel for using magnets to levitate a frog.
The point: A friendly reminder that the IgNobel awards are not here to point fingers at the useless and foolish in science, but, rather, to draw attention to studies that sound funny, but often have some serious thought going on behind the guffaws. Geim's IgNobel, for instance, was earned in honor of research that involved using a popular magnet toy to make a frog float. But, that research is centered around serious ideas about magnetic levitation, a phenomenon best known for its application in Maglev trains.
One note: Technically, Geim is only the first person to win both awards as an individual.
Bart Knols, who (together with Ruurd de Jong) was awarded the 2006 Ig Nobel Prize in Entomology (for showing that the female malaria mosquito Anopheles gambiae is attracted equally to the smell of limberger cheese and to the smell of human feet) was also one of the hundreds of employees of the International Atomic Energy Agency who together were awarded a Nobel Prize in peace in 2005.
