Juan Manuel Rodríguez ParrondoWhile Spanish scientists normally use the first of their two surnames when publishing in English-speaking journals, Parrondo publishes under his second surname, Rodríguez being his father's surname and a very common surname in Spain, and Parrondo being his mother's surname.In various sources Parrondo's name is sometimes incorrectly spelled "Parrando," an error that can be traced to a 25 January 2000 article on "Parrando's Paradox" (sic) in the New York Times that propagated the incorrect spelling.{{citation needed|date=June 2013}} (born 9 January 1964) is a Spanish physicist.{{not verified in body|date=June 2013}} He is mostly popular for the invention of the Parrondo's paradox and his contributions in the thermodynamical study of information.{{Cite journal|last1=Sagawa|first1=Takahiro|last2=Horowitz|first2=Jordan M.|last3=Parrondo|first3=Juan M.
