Welcome to this third episode of our special Nobel Prize editions of Science Talk,

the podcast of Scientific American.

I'm Steve Murski. Today, the Chemistry of Scientific American. I'm Steve Merski. Today, the

chemistry prize. This year's prize is about how the optical microscope became a

nonoscope. Royal Swedish Academy of Sciences permanent secretary Stefan Normark.

The Royal Swedish Academy of Sciences has decided to award the 2014 Nobel Prize in Chemistry to Dr. Eric Betzig at Howard Hughes Medical Institute, Ashbourne, USA.

Professor Stefan Hell at Max Planck Institute for Biophysical Chemistry, Göttingen, and the German Cancer Research Center,

Heidelberg, Germany, and Professor William Marner at Stanford University, Stanford, USA.

For the development of super-resolved fluorescence microscopy.

A little background as you continue to listen.

You'll hear the members

of the committee refer to the Abbey diffraction limit or the Abbey condition. German physicist Ernst
