       | I read in Friedrich Hund's Wikipedia biography that while he was
       | in Jena in after WWII in East Germany, the head of the Thuringen
       | state government awarded him in 1949.... a voucher for a pair of
       | shoes (a copy of the letter is on Wikipedia) as recognition of
       | his academic merits.
       | 
       | He ended up emigrating to the West in 1951, and thus avoided the
       | bloody 1953 Soviet repression of unions demands in Jena. Question
       | to Germans: Was the shoe voucher a more or less hidden message,
       | or just typical postwar East German socialism?

         | What always struck me was Eastern Germans' tendency to
         | practical things (and an enormous creativity in fixing broken
         | stuff!). In addition, this is 1949 Eastern Germany, the country
         | was devastated and this part under Soviet rule. It might sound
         | a bit weird as a gift from today's wealthy point of view but
         | historically "a good pair of shoes" was always something people
         | appreciated throughout all times and cultures.

           | (It seems I am indulging in anecdotes a bit in this page, but
           | anyway) In the portrait of "Lenin" Ulyanov by Paul Johnson in

           | 
           | > _Lenin left Zurich to return to Russia on 8 April 1917.

         | A famous great anecdote about Dirac (and Bohr and Rutherford)

         | 
         |  _Young Dirac arrived at Niels Bohr's institute with a glowing
         | recommendation from the great experimentalist Ernest
         | Rutherford. A few months later, Bohr remarked to Rutherford
         | that this marvelous Dirac hardly seemed so special: he said
         | nothing and he did nothing. Legend has it that Rutherford
         | replied with the following story:_
         | 
         |  _A man went to a pet shop to buy a parrot. There was a gray
         | parrot that knew a few words selling for one hundred dollars.
         | There was a blue parrot that could sing and tell stories for
         | two hundred dollars. There was a beautiful green and purple
         | bird that spoke several ancient languages for five hundred
         | dollars. And there was a nondescript brown bird priced at a
         | thousand dollars._
         | 
         |  _"A thousand dollars!" exclaimed the would-be buyer. "That
         | must be some bird - how many languages does he speak?"_ _"Just
         | English," admitted the shopkeeper._
         | 
         |  _"His vocabulary is extraordinary, perhaps?"_ _The shopkeeper
         | shrugged. "Not really"._
         | 
         |  _"Does he sing, then?"_ _"No," said the shopkeeper. "Most days
         | this parrot doesn't even talk"._
         | 
         |  _"Well, does he do acrobatic tricks or something? What on
         | earth is so valuable about that parrot?"_
         | 
         |  _"Sir, this parrot thinks"._
         | 
         |  _Rutherford concluded, "Dirac thinks"._
