Hermann Bondi
Sir Hermann Bondi (1 November 1919 – 10 September 2005) was an Austrian-British mathematician and cosmologist. He is best known for developing the steady state model of the universe with Fred Hoyle and Thomas Gold as an alternative to the Big Bang theory. He contributed to the theory of general relativity,Obituaries: Professor Sir Hermann Bondi(12 September 2005) in ''The Independent''. Professor Sir Hermann Bondi(2005-09-13) in ''The Telegraph''.

Mass In General Relativity
The concept of mass in general relativity (GR) is more subtle to define than the concept of mass in special relativity. In fact, general relativity does not offer a single definition of the term mass, but offers several different definitions that are applicable under different circumstances. Under some circumstances, the mass of a system in general relativity may not even be defined. The reason for this subtlety is that the energy and momentum in the gravitational field cannot be unambiguously localized. (See Chapter 20 of .) So, rigorous definitions of the mass in general relativity are not local, as in classical mechanics or special relativity, but make reference to the asymptotic nature of the spacetime. A well defined notion of the mass exists for asymptotically flat spacetimes and for asymptotically Anti-de Sitter space. However, these definitions must be used with care in other settings. Defining mass in general relativity: concepts and obstacles In special relativity, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alec Broers
Alec Nigel Broers, Baron Broers, (born 17 September 1938) is a British electrical engineer. In 1994 Broers was elected an international member of the National Academy of Engineering for contributions to electronic beam lithography and microscopy and for leadership in microfabrication. Education and early life Broers was born in Calcutta, India and educated at Geelong Grammar School and Melbourne University in Australia and at University of Cambridge (Gonville and Caius College) in England. Career Broers then worked in the research and development laboratories of IBM in the United States for 19 years before returning to Cambridge in 1984 to become Professor of Electrical Engineering (1984–96) and Fellow of Trinity College, Cambridge (1985–90). He is a pioneer of nanotechnology. Broers subsequently became Master of Churchill College, Cambridge (1990–96) and Head of the Cambridge University Engineering Department (1993–96).

Churchill College, Cambridge
Churchill College is a constituent college of the University of Cambridge, England. It has a primary focus on science, engineering and technology, but still retains a strong interest in the arts and humanities. In 1958, a trust was established with Sir Winston Churchill as its chairman of trustees, to build and endow a college for 60 fellows and 540 students as a national and Commonwealth memorial to Winston Churchill; its Royal Charter and Statutes were approved by the Queen, in August 1960. It is situated on the outskirts of Cambridge, away from the traditional centre of the city, but close to the University's main new development zone (which now houses the Centre for Mathematical Sciences). It has of grounds, the largest area of the Cambridge colleges. Churchill was the first formerly all-male college to decide to admit women, and was among three men's colleges to admit its first women students in 1972. Within 15 years all others had followed suit. The college has a re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biographical Memoirs Of Fellows Of The Royal Society
The ''Biographical Memoirs of Fellows of the Royal Society'' is an academic journal on the history of science published annually by the Royal Society. It publishes obituaries of Fellows of the Royal Society. It was established in 1932 as ''Obituary Notices of Fellows of the Royal Society'' and obtained its current title in 1955, with volume numbering restarting at 1. Prior to 1932, obituaries were published in the ''Proceedings of the Royal Society''. The memoirs are a significant historical record and most include a full bibliography of works by the subjects. The memoirs are often written by a scientist of the next generation, often one of the subject's own former students, or a close colleague. In many cases the author is also a Fellow. Notable biographies published in this journal include Albert Einstein, Alan Turing, Bertrand Russell, Claude Shannon, Clement Attlee, Ernst Mayr, and Erwin Schrödinger. Each year around 40 to 50 memoirs of deceased Fellows of the Royal Soci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Order Of The Bath
The Most Honourable Order of the Bath is a British order of chivalry founded by George I of Great Britain, George I on 18 May 1725. The name derives from the elaborate medieval ceremony for appointing a knight, which involved Bathing#Medieval and early-modern Europe, bathing (as a symbol of purification) as one of its elements. The knights so created were known as "Knights of the Bath". George I "erected the Knights of the Bath into a regular Order (honour), Military Order". He did not (as is commonly believed) revive the Order of the Bath, since it had never previously existed as an Order, in the sense of a body of knights who were governed by a set of Statute, statutes and whose numbers were replenished when vacancies occurred. The Order consists of the Sovereign (currently Charles III, King Charles III), the :Great Masters of the Order of the Bath, Great Master (currently vacant) and three Classes of members: *Knight Grand Cross (:Knights Grand Cross of the Order of the Bath ...

Gold Medal Of The Royal Astronomical Society
The Gold Medal of the Royal Astronomical Society is the highest award given by the Royal Astronomical Society (RAS). The RAS Council have "complete freedom as to the grounds on which it is awarded" and it can be awarded for any reason. Past awards have been given for "outstanding personal researches in the fields of astronomy and geophysics" as well as general contributions to astronomy and geophysics "that may be made through leadership in research programmes, through education and through scientific administration". It has been awarded both for research that has taken a lifetime (it has most frequently been given to recognise an extraordinary lifetime achievement), and for specific pieces of research. History The RAS was founded in 1820 and the first Gold Medals were awarded in 1824. Silver medals were also awarded in 1824 and 1827, but that practice was quickly abandoned, instead the RAS established other awards. In the early years, more than one medal was often awarded in a ...
