DESCRIPTION:Seminar Title:\n\nHow to overcome a supposed scientific barrier
  ... and what to make of it\n\n \n\nAbstract:\n\nIn the 20th century\, it 
 was assumed that the resolution of a light microscope could not be increas
 ed beyond 200 nm. This limit was attributed to the wave nature of light an
 d the resulting phenomenon of diffraction. I show - not least on the basis
  of my autobiography - how this limit has been radically overcome in fluor
 escence microscopy. Recent developments such as MINFLUX and MINSTED micros
 copy even achieve resolutions of 1-3 nm\, which is about the size of the f
 luorescence molecules themselves. The hundredfold better resolution and mo
 lecular dynamics that can be measured with these new methods open up compl
 etely new fields of application for light microscopy in biomedicines.\n\n 
 \n\nBio:\n\nStefan Hell is a director at both the Max Planck Institute for
  Multidisciplinary Sciences in Göttingen and the Max Planck Institute for 
 Medical Research in Heidelberg\, Germany.\n\nHell is credited with having 
 conceived\, validated and applied the first viable concept for overcoming 
 Abbe’s diffraction-limited resolution barrier in a light-focusing fluoresc
 ence microscope. For this accomplishment he has received numerous awards\,
  including the 2014 Kavli Prize in Nanoscience and the Nobel Prize in Chem
 istry.\n\nStefan Hell received his doctorate (1990) in physics from the Un
 iversity of Heidelberg. From 1991 to 1993 he worked at the European Molecu
 lar Biology Laboratory\, followed by stays as a senior researcher at the U
 niversity of Turku\, Finland\, between 1993 and 1996\, and as a visiting s
 cientist at the University of Oxford\, England\, in 1994. In 1997 he was a
 ppointed to the MPI for Biophysical Chemistry (now MPI for Multidisciplina
 ry Sciences) in Göttingen as a group leader\, and was promoted to director
  in 2002.\n
