Question: What is the birthdate of this American physicist who won the Nobel Prize in Physics and led a group of eminent researchers in the World Federation of Scientists?
Context: Jerome Isaac Friedman (born March 28, 1930) is an American physicist.  He is Institute Professor and Professor of Physics, "Emeritus, "at the Massachusetts Institute of Technology.  He won the 1990 Nobel Prize in Physics along with Henry Kendall and Richard Taylor, for work showing an internal structure for protons later known to be quarks.  Dr. Friedman currently sits on the Board of Sponsors of the "Bulletin of the Atomic Scientists". George Mavrikos (born 1950) is the General Secretary of the World Federation of Trade Unions (WFTU) in Athens, Greece.  He is a leading member of the Communist Party of Greece (KKE), and former member of Greek parliament.  He is largely credited for having led the successful efforts to halt the decline of the World Federation of Trade Unions since the fall of the Soviet Union.  Since his election as general secretary during the congress in Havana in 2005, the World Federation of Trade Unions has seen an increase in its number of affiliates and has successfully managed to recruit several trade union of importances in Western Europe. Since 1901, the Nobel Prize in Literature (Swedish: "Nobelpriset i litteratur" ) has been awarded annually to an author from any country who has, in the words of the will of Alfred Nobel, produced "in the field of literature the most outstanding work in an ideal direction" (original Swedish: "den som inom litteraturen har producerat det mest framstående verket i en idealisk riktning").  Though individual works are sometimes cited as being particularly noteworthy, here "work" refers to an author's work as a whole.  The Swedish Academy decides who, if anyone, will receive the prize in any given year.  The academy announces the name of the chosen laureate in early October.  It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895; the others are the Nobel Prize in Chemistry, Nobel Prize in Physics, Nobel Peace Prize, and Nobel Prize in Physiology or Medicine. The Society for Research on Biological Rhythms (SRBR) is an international chronobiological research society with three key goals: (1) to promote the advancement and dissemination of basic and applied research in all aspects of biological rhythms; (2) to enhance the education and training of students and researchers in the field; (3) to foster interdisciplinary communication and an international exchange of ideas.The society holds biennial meetings and informal gatherings, and participates in peer-reviewed science and evidence-based policymaking.  It is one of four prominent existing Chronology Research Societies and one of the 14 societies that make up The World Federation of Societies for Chronobiology.  The organization is currently composed of 1,000 scientists and clinicians dedicated to studying biological rhythms and their impact.  The society has its own official journal, the Journal of Biological Rhythms.  Through its journal, website, meetings and exchanges the society engages scientists of all backgrounds and nationalities.  It advocates the need for funding in research areas in biological rhythms, such as sleep, and supports other research efforts such as the National Institutes of Health and National Science Foundation. The Tahiti International is an international badminton tournament held in Tahiti, French Polynesia organised by Tahiti Badminton Federation, sanctioned by Badminton World Federation (BWF) and Badminton Oceania.  In the last few years, this tournament has been an BWF International Challenge with total prize money US$17.500.  In fact, this tournament established since 2009, but not yet sanctioned by the Badminton World Federation. The Nobel Prize in Physics (Swedish: "Nobelpriset i fysik" ) is a yearly award given by the Royal Swedish Academy of Sciences for those who conferred the most outstanding contributions for mankind in the field of physics.  It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895 and awarded since 1901; the others being the Nobel Prize in Chemistry, Nobel Prize in Literature, Nobel Peace Prize, and Nobel Prize in Physiology or Medicine. The Nobel Prize in Physiology or Medicine (Swedish: "Nobelpriset i fysiologi eller medicin" ) is awarded annually by the Swedish Karolinska Institute to scientists and doctors in the various fields of physiology or medicine.  It is one of the five Nobel Prizes established by the 1895 will of Alfred Nobel (who died in 1896), awarded for outstanding contributions in chemistry, physics, literature, peace, and physiology or medicine.  As dictated by Nobel's will, the award is administered by the Nobel Foundation and awarded by a committee that consists of five members and an executive secretary elected by the Karolinska Institute.  While commonly referred to as the Nobel Prize in Medicine, Nobel specifically stated that the prize be awarded for "physiology or medicine" in his will.  Because of this, the prize can be awarded in a broader range of fields.  The first Nobel Prize in Physiology or Medicine was awarded in 1901 to Emil Adolf von Behring, of Germany.  Each recipient receives a medal, a diploma and a monetary award that has varied throughout the years.  In 1901, von Behring received 150,782 SEK, which is equal to 7,731,004 SEK in December 2008.  In 2013, the prize was awarded to James E. Rothman, Randy W. Schekman and Thomas C. Südhof; they were recognised "after discovering how cells precisely transport material".  The award is presented in Stockholm at an annual ceremony on December 10, the anniversary of Nobel's death. Isidor Isaac Rabi ( ; born Israel Isaac Rabi, 29 July 1898 – 11 January 1988) was an American physicist who won the Nobel Prize in Physics in 1944 for his discovery of nuclear magnetic resonance, which is used in magnetic resonance imaging.  He was also one of the first scientists in the United States to work on the cavity magnetron, which is used in microwave radar and microwave ovens. The World Federation of Scientists is a multi-disciplinary association of scientists focused around concentrating talent to solving planetary challenges.  Established in Erice, Sicily in 1973 by a group of eminent researchers led by Isidor Isaac Rabi and Antonino Zichichi, it has grown to include more than 10,000 scientists drawn from 110 countries.  Notable scientists involved with the association include T. D. Lee, Laura Fermi, Eugene Wigner, Paul Dirac, and Piotr Kapitza. The Nobel Prize in Chemistry (Swedish: "Nobelpriset i kemi" ) is awarded annually by the Royal Swedish Academy of Sciences to scientists in the various fields of chemistry.  It is one of the five Nobel Prizes established by the 1895 will of Alfred Nobel, who died in 1896.  These prizes are awarded for outstanding contributions in chemistry, physics, literature, peace, and physiology or medicine.  As dictated by Nobel's will, the award is administered by the Nobel Foundation and awarded by a committee that consists of five members elected by the Royal Swedish Academy of Sciences.  The first Nobel Prize in Chemistry was awarded in 1901 to Jacobus Henricus van 't Hoff, of the Netherlands.  Each recipient receives a medal, a diploma and a monetary award prize that has varied throughout the years.  In 1901, van 't Hoff received 150,782 SEK, which is equal to 7,731,004 SEK in December 2007.  The award is presented in Stockholm at an annual ceremony on December 10, the anniversary of Nobel's death.
