Information:  - Sir Joseph John Thomson (18 December 1856  30 August 1940) was an English physicist. He was elected as a fellow of the Royal Society of London and appointed to the Cavendish Professorship of Experimental Physics at the Cambridge University's Cavendish Laboratory in 1884.  - An academy of sciences is a type of learned society or academy (as special scientific institution) dedicated to sciences that could be or not state funded. Some state funded academies are tuned into national or royal (in case of the United Kingdom i.e. Royal Society of London for Improving Natural Knowledge) as a form of honor. The other types of academy is an academy of arts (see Academy of Arts) or combination of both (i.e. American Academy of Arts and Sciences).  - The Hughes Medal is awarded by the Royal Society of London "in recognition of an original discovery in the physical sciences, particularly electricity and magnetism or their applications". Named after David E. Hughes, the medal is awarded with a gift of £1000. The medal was first awarded in 1902 to J. J. Thomson "for his numerous contributions to electric science, especially in reference to the phenomena of electric discharge in gases", and has since been awarded over one-hundred times. Unlike other Royal Society medals, the Hughes Medal has never been awarded to the same individual more than once. A recent recipient was Michele Dougherty, who was awarded the medal "for innovative use of magnetic field data that led to discovery of an atmosphere around one of Saturn's moons and the way it revolutionised our view of the role of planetary moons in the Solar System".  - A royal charter is a formal document issued by a monarch as letters patent, granting a right or power to an individual or a body corporate. They were, and are still, used to establish significant organisations such as cities (with municipal charters) or universities and learned societies. Charters should be distinguished from warrants and letters of appointment, as they have perpetual effect. Typically, a Royal Charter is produced as a high-quality work of calligraphy on vellum. The British monarchy has issued over 980 royal charters. Of these about 750 remain in existence. The earliest was to the town of Tain in 1066, making it the oldest Royal Burgh in Scotland, followed by the University of Cambridge in 1231. Charters continue to be issued by the British Crown, a recent example being that awarded to the Chartered Institute for the Management of Sport and Physical Activity, on 7 April 2011.  - The President, Council and Fellows of the Royal Society of London for Improving Natural Knowledge, commonly known as the Royal Society, is a learned society for science and is possibly the oldest such society still in existence. Founded in November 1660, it was granted a royal charter by King Charles II as "The Royal Society". The Society is the United Kingdom's and Commonwealth of Nations' Academy of Sciences and fulfills a number of roles; promoting science and its benefits, recognising excellence in science, supporting outstanding science, providing scientific advice for policy, fostering international and global cooperation, education and public engagement.  The society is governed by its Council, which is chaired by the Society's President, according to a set of statutes and standing orders. The members of Council and the President are elected from and by its Fellows, the basic members of the society, who are themselves elected by existing Fellows. As of 2016, there are about 1,600 fellows, allowed to use the postnominal title FRS (Fellow of the Royal Society), with up to 52 new fellows appointed each year. There are also royal fellows, honorary fellows and foreign members, the last of which are allowed to use the postnominal title ForMemRS (Foreign Member of the Royal Society). The Royal Society President is Venkatraman Ramakrishnan, who took up the post on November 30, 2015.  - A learned society (also known as a learned academy, scholarly society or academic association) is an organization that exists to promote an academic discipline or profession, or a group of related disciplines or professions. Membership may be open to all, may require possession of some qualification, or may be an honor conferred by election.  - Venkatraman "Venki" Ramakrishnan (born 1952) is an Indian-American-British structural biologist of Indian origin. He is the current President of the Royal Society, having held the position since November 2015. In 2009 he shared the Nobel Prize in Chemistry with Thomas A. Steitz and Ada Yonath, "for studies of the structure and function of the ribosome".   - Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.  - Fellowship of the Royal Society (FRS, ForMemRS & HonFRS) is an award and fellowship granted by the Royal Society of London to individuals the society judges to have made a "substantial contribution to the improvement of natural knowledge, including mathematics, engineering science and medical science".  - Michele Karen Dougherty FRS (born 1962) is a Professor of Space Physics at Imperial College London. She is leading unmanned exploratory missions to Saturn and Jupiter and is Principal Investigator for J-MAG - a magnetometer for the JUpiter ICy moons Explorer (JUICE) of the European Space Agencies (ESA) due for launch June 2022.  - Alexander Boksenberg CBE FRS ( born 17 March 1936 ) is a British scientist . He won the 1999 Hughes Medal of the Royal Society `` for his landmark discoveries concerning the nature of active galactic nuclei , the physics of the intergalactic medium and of the interstellar gas in primordial galaxies . He is noted also for his exceptional contributions to the development of astronomical instrumentation including the Image Photon Counting System , a revolutionary electronic area detector for the detection of faint sources , which gave a major impetus to optical astronomy in the United Kingdom '' . He later served as the Director of the Royal Greenwich Observatory .    Given the information, choose the subject and object entities that have the relation of 'occupation'.
