Context: Engineering is the application of mathematics and scientific, economic, social, and practical knowledge in order to invent, innovate, design, build, maintain, research, and improve structures, machines, tools, systems, components, materials, processes, solutions, and organizations., Astronomy is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution. Objects of interest include planets, moons, stars, galaxies, and comets; while the phenomena include supernovae explosions, gamma ray bursts, and cosmic microwave background radiation. More generally, all astronomical phenomena that originate outside Earth's atmosphere are within the purview of astronomy. A related but distinct subject, physical cosmology, is concerned with the study of the Universe as a whole., 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., Ancient Han Chinese scientists, engineers, astronomers, philosophers, mathematicians and medical doctors made significant innovations, scientific discoveries and technological advances in science, technology, engineering, medicine, military technology, mathematics, geology and astronomy., Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe., Lu Gwei - djen ( Chinese :  ; pinyin : L Guìzhn ; Wade -- Giles : Lu Kui - chen ) ( July 22 , 1904  Nov 28,1991 ) was an expert on the history of science and technology in China and a doctor of nutriology . She was an important researcher and co-author of the project Science and Civilisation in China led by Joseph Needham ., Military technology is the application of technology for use in warfare. It comprises the kinds of technology that are distinctly military in nature and not civilian in application, usually because they lack useful or legal civilian applications, or are dangerous to use without appropriate military training., Medicine (British English ; American English ) is the science and practice of the diagnosis, treatment, and prevention of disease. The word "medicine" is derived from Latin "medicus", meaning "a physician". Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others., The Han Chinese, Han people or simply Han (; pinyin: "Hànzú", literally "Han ethnicity" or "Han ethnic group"; or ; pinyin: "Hànrén", literally "Han people") are an ethnic group native to East Asia. They constitute approximately 92% of the population of China, 95% of Taiwan (Han Taiwanese), 76% of Singapore, 23% of Malaysia and about 18% of the global population. Han Chinese are the world's largest ethnic group with over 1.3 billion people., Technology ("science of craft", from Greek , "techne", "art, skill, cunning of hand"; and , "-logia") is the collection of techniques, skills, methods and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation. Technology can be the knowledge of techniques, processes, and the like, or it can be embedded in machines which can be operated without detailed knowledge of their workings., The British Academy is the United Kingdom's national academy for the humanities and the social sciences., Science and Civilisation in China (1954[2015]) is a series of books initiated and edited by British biochemist, historian and sinologist Sir Joseph Needham, Ph.D (19001995). They deal with the history of science and technology in China. To date there have been seven volumes in twenty-seven books. The series was on the Modern Library Board's 100 Best Nonfiction books of the 20th century., A historian is a person who researches, studies, and writes about the past, and is regarded as an authority on it. Historians are concerned with the continuous, methodical narrative and research of past events as relating to the human race; as well as the study of all history in time. If the individual is concerned with events preceding written history, the individual is a historian of prehistory. Although "historian" can be used to describe amateur and professional historians alike, it is reserved more recently for those who have acquired graduate degrees in the discipline. Some historians, though, are recognized by publications or training and experience. "Historian" became a professional occupation in the late nineteenth century as research universities were emerging in Germany and elsewhere., Noel Joseph Terence Montgomery Needham (9 December 1900  24 March 1995) was a British scientist, historian and sinologist known for his scientific research and writing on the history of Chinese science. He was elected a fellow of the Royal Society in 1941, and a fellow of the British Academy in 1971. In 1992, the Queen conferred on him the Companionship of Honour, and the Royal Society noted he was the only living person to hold these three titles., Geology (from the Ancient Greek , "g", i.e. "earth" and -o, "-logia", i.e. "study of, discourse") is an earth science comprising the study of solid Earth, the rocks of which it is composed, and the processes by which they change. Geology can also refer generally to the study of the solid features of any terrestrial planet (such as the geology of the Moon or Mars)., Biochemists are scientists that are trained in biochemistry. Description. Typical biochemists study chemical processes and chemical transformations in living organisms, other biochemists study DNA, proteins and cell parts. The word "biochemist" is a portmanteau of "biological chemist"., Subject: lu gwei-djen, Relation: occupation, Options: (A) biochemist (B) engineering (C) historian (D) king (E) member (F) military (G) physics (H) president (I) research (J) science (K) scientist (L) sinologist (M) taiwan (N) united kingdom
