Eric Betzig interviewed for l'X on Air

Eric Betzig, who was awarded the 2014 Nobel prize in Chemistry, came at École Polytechnique on Tuesday, 16 June 2015.

Eric Betzig, Professor at the Janelia Research Campus in Ashburn, Virginia, came at École Polytechnique on Tuesday, 16 June 2015 to give a conference on "Imaging life at high spatiotemporal resolution". This conference was organized by École Polytechnique Physics department.

The American scientist was awarded the Nobel prize in chemistry along with Stefan Hell and William E. Moerner for their research in the field of microscopy which opened the way to "nanoscopy".
Thanks to their work, it is now possible for scientists to visualize the movement of molecules within living cells at very small time scales.

Before them, it was impossible to observe living cells at a scale smaller than 250 nanometers, because of the diffraction limit of light as developed by the scientist Ernst Abbe in 1873. According to this theory, the light reflected by a nanoscale object merges with that of the elements found nearby. The winners of the 2014 Nobel Prize found a way around around that problem by using fluorescent molecules.

In this video, Eric Betzig tells us about his career and his discovery and gives precious advice to École Polytechnique students.
