Royal Society definition

Thus, the Taylor and Francis publishing house not only provided the where-withal for the publication of the proceedings, transactions, and journals of major scientific societies throughout Great Britain, including the Philosophical Transactions of the Royal Society, but also played a substantial role in refining the definitions of disciplinary specialties like physics and chemistry throughout the nineteenth century. 

Unfortunately because nano has become somewhat of a buzzword and is currently attracting a lot of research funding, the term is being used loosely to cover a huge range of topics and techniques to do with anything that is fairly small, and it can be difficult to separate what is important. The Royal Society has come up with two working definitions ... 

So far, we have identified coordination compounds only by their chemical formulas, but names are also useful for many purposes. Some substances were named before their structures were known. Thus, K3[Fe(CN)g] was called potassium fer-ricyanide, and K4[Fe(CN)g] was potassium ferrocyanide [these are complexes of Fe (ferric) and Fe (ferrous) ions, respectively]. These older names are still used conversationally but systematic names are preferred to avoid ambiguity. The definitive source for the naming of inorganic compounds is Nomenclature of Inorganic Chemistry-IUPAC Recommendations 2005 (N. G. Connelly and T. Damhus, Sr., Eds. Royal Society of Chemistry, 2005). 

He was one of the earliest supporters of the doctrine of bodies combining in definite proportions, or of what is commonly called the atomic theory. Previous to introducing a paper of his in which this doctrine is happily illustrate by new and curious facts, I shall give a short historical sketch equally candid and perspicuous of the origin of this doctrine, and of its progress, vdiich forms a part of the Discourse he delivered as President of the Royal Society on the awardment of the first Royal medal to Mr. Dalton "for the developement of Ae chemical theory of definite proportions." -He proceeds, - "What Mr Daltons merits are, I shall briefly endeavor to state to you, though it is impossible to do justice to them in the time necessarily allotted to this address.""...

In 1983 an important report [1] appeared which defined hazard and risk. It emanated from the United Kingdom s Royal Society, and resulted from a study group concerned with risk assessment for engineering and health risks. Definitions of hazard and risk were further elaborated by a Working Party of the United Kingdom s Institution of Chemical Engineers... 

Some of his research during this period (Armstrong, 1921) concerned the rate of enzyme action, and his work was cited when Michaelis and Menten published their definitive theory in 1913. He was, however, some way from anticipating their treatment of the kinetics, except in clearly recognising the intermediate formation of an enzyme-substrate complex, and the effect this would have on the rate of reaction. This process would explain the apparent deviations in the rate from a law of mass action based on the reagent concentrations alone (Brown, 1902). He was elected to the Royal Society in 1911, and he died in 1919, a greatly respected member of the university (Plate 1.1). 

The first non systematic introduction of thermodynamics in Chemical Kinetics is due to the second couple of scientists previously cited Augustus George Vernon Harcourt (1834-1919) and William Esson (1839-1916). Harcourt was an important chemist, member of the Royal society and president of Chemical society, Esson a mathematician and Savilian professor of Geometry. They worked at University of Oxford in a period particularly fruitful for Sciences in Britain. It is the peak of positivism and at the time different sciences, included chemistry, got clearly distinct university courses. Their activity covered a period of fifty years and represented the main passage from natural philosophy speculations to modern scientific reasoning. Influenced by Van t Hoff they will definitively abandon ambiguous terms like Affinity and Chemical Forces. 

It is not surprising therefore that tiie definitions of risk can be complex. The Royal Society Study Group report offers the following definition ... 

The above comments are made to introduce the subject of units (and symbols) but the definitive documents on symbols for chemists are the Royal Society s Quantities, Units, and Symbols (1971) and the lUPAC Manual of Symbols and Terminology for Physicochemical Quantities and Units . ... 

Since the early talks of Richard Feynman in its There s Plenty of Room at the Bottom in 1959, there have been always a concern on what nano means and applies to. Recently, the Royal Society tried to make order between the definitions of nanoscience and nanotechnology, both referring to, respectively, the study or the preparation of materials from 100 nm down to the atomic level (approximately 0.2 nm) [1], Later, the British Standard Institution defined nanomaterial as material having one or more external dimensions in the nanoscale or which is nanostructured. [2] Accordingly, Murray makes a noticeable attempt to apply these concepts to nanoelectrochemistry of nanoparticles, nanoelectrodes, and nanopores, referring them as a dimensional scale of electrodes and electrochemical events [3]. 

First are its mathematical foundations. In 1953 an intuitive commonplace amongst mathematicians was definitively proven by a Russian researcher. L.l. Kamynin showed that the method of finite differences, invented long before by the English mathematician and Royal Society alumnus Brook Taylor (1685-1731), was reliable. Small finite quantities, amenable to computer manipulation, replace the infinitesimal quotients of partial differential equations, mathematical models that describe physical processes, which would otherwise be insoluble. This intellectual tool took discrete points along a continuum of some kind, a mathematical function or a curving structural element, then found the conditions at those points and in between.
