From Denis Weaire, Trinity College Dublin
In “When science gets it wrong” (21 May, p 28) you presented the excellent example of the diffraction limit in microscopy, surpassed in 1984 by the invention of the near-field scanning optical microscope.
At a conceptual level, this technique was described in publications by Edward H. Synge, who corresponded on the subject with Albert Einstein, . Synge will be celebrated in a symposium at Trinity College Dublin in 2012, as a late recognition of this achievement, among others, with which few are familiar.
