Berzelius 2 p.12 "It was a giant work one of the most importent in the history of chemistry which was here presented. One is even more impressed when one remembers that it was a pioneer undertaking in every sense of the term.

They all had to be elaborated at the cost of time and labour."J. Erik Jorpes "Jac. Berzelius" p.45.<br><br>"In general Berzelius's efforts were directed toward the consolidation and extension of the atomic theory. He improved chemical analysis and determined the composition of a large number of compounds thus verifying the laws of constant and multiple proportions and furnishing the most accurate equivalent weights then available.

Entire volume: 6 605 pp. 40 photographic plates. � First edition of Turing's hugely influential paper which some consider to be the spark of modern chaos theory and a testament to his multifaceted genius. With the present paper Turing was the first to offer an explanation of morphogenesis through chemistry. He theorized that identical biological cells differentiate change shape and create patterns through a process called intercellular reaction-diffusion.<br><br>In this model a system of chemicals react with each other and diffuse across a space such as between cells in an embryo. These chemical reactions need an inhibitory agent to suppress the reaction and an excitatory agent to activate the reaction. This chemical reaction diffused across an embryo will create patterns of chemically different cells. Turing's theory that patterns emerge or self-organize as a result of the individual parts interacting was immensely influential in a number of areas: <br>"Applications of Turing's work to developmental biology are too numerous to list but include limb development pigmentation patterning hair and feather germ formation tooth morphogenesis phyllotaxis hydra patterning and regeneration. Moreover ideas of self-organization now abound in biology chemistry and ecology. The stimulus for a lot of this work stems from Turing's original ideas. Although still very controversial Turing's theory for morphogenesis provided a paradigm shift in our way of thinking" Maini Alan Turing: his work and impact<br><br>"Throughout his life Turing was also interested in applying mathematical and mechanical theory to the biological problem of life forms. He made a promising approach to this question in his 1952 publication "The Chemical Basis of Morphogenesis." In this work he exploited the mathematical demonstration that small variations in the initial conditions of first-order systems of differential equations may result in appreciable deviations in the asymptotic behavior of their solutions to posit that unknown functions might function biologically as form-producers; he was thus able to account for asymmetry in both mathematical and biological form. He was at work on a general theory when he died of perhaps accidental poisoning." DSB<br><br>"In his final years Turing worked on . Artificial Life A-Life. The central aim of A-Life is a theoretical understanding of naturally-occurring biological life - in particular. its ability to self-organize i.e. to develop form and structure spontaneously . Turing was the first to use computer simulation to investigate a theory of 'morphogenesis'.he began this investigation as soon as the first Ferranti Mark to be produced was installed at Manchester University . In June 1954 in the midst of this groundbreaking work Turing died." Copeland Alan Turing's Electronic Brain hardcover‎

In october 1836 W�hler wrote that he had discovered a way to transform amygdalin to oil of bitter almonds and hydrocyanid acis by distilling it with manganese and sulfuric acid and he invited Liebig to join in pursuing the topic. Two days later he made a more remarkable discovery. It had occurred to him that perhaps thetransformation of amygdalin could be effected by the albumin in the almonds in a manner similar to the action of yeast in sugar.W�hler suspected that the decomposition was an example of what Berzelius had recently defined as catalysis. Liebig and W�hler then divided up the detailed examination of the properties and composition of amygdalin. They precipitated from the emulsion of almonds a substance which when dissolved retain its action. They named the active substance "emulsion".

The theory of molecular constitution put foreward.by Couper and Kekul� rested on two main postulates the quadriivalency of carbon.and the capacity of the carbon atom for mutual linking or combining together to form a carbon "chain". By this hypothesis of the mutual linking together of carbon atoms - which waslater confirmed by experiment - it was possible to explain the formation of organic compounds containing a large number of carbon atoms. On the foundation of their postulates two postulates moreover they showed how the molecular constitution or mutual linking together of the atoms of a compound could be represented diagrammatically and the relstions between different compounds made readily intelligible. In his classic paper "On a New Chemical Theory" the paper offered here in its first appearance advanced beyond Kekul� by representing the constitutions of the compounds by means of GRAPHIC FORMULA in which as at the present day the valencies pf the atoms are represented by lines.his formulae are similar to those at present in use."Findlay pp. 34 ff<br><br>"The theory of Kekul� and Couper gave the chemists the maeans of solving the problems of chemical constitution; and by means of the graphic or constitutional formulae it became possible to represent the molecular constitution of known compounds and to foresee the possible existence of isomeric compounds."Findlay.<br>Parkinson "Breakthroughs" 1858 C.<br><br>The volume contains another importent monumental memoir MARCELLIN BERTHELOT "Sur la Synth�se des Carbures D'Hydrogene" pp. 69-208.

"This led not only to the Kekul� structures but also to the periodic table of Mendel�ev since that table was based on the regular change of valence with atomic weight."Asimov.<br><br>"On May 10 1852 Frankland read to the Royal Society a paper on organic metallic compounds the paper offered in which he made the emperical observation that elements possessed fixed combining powers or "only room so to speak for the attachement of a fixed and definite number of the atoms of other elements." The expression "valence" or "Valency" began to be used by other chemists only after 1865 wheras Frankland tended to use the misleading term "atomicity".Frankland's teching position at the Royal College of Chemistry and his influence on the Department of Sciences and Art science examinations enembled him to spread the idea through the younger generation of British chemists."DSB V p. 126.<br><br>The exact inception however of the theory of chemical valencies can be traced to an 1852 paper by Edward Frankland in which he combined the older theories of free radicals and "type theory" with thoughts on chemical affinity to show that certain elements have the tendency to combine with other elements to form compounds containing 3 i.e. in the three atom groups e.g. NO3 NH3 NI3 etc. or 5 i.e. in the five atom groups e.g. NO5 NH4O PO5 etc. equivalents of the attached elements.

The papers were published at the same time in Swedish German both here in Annalen and in Schweiger's Journal and in French. By running many hundreds of analysis of chemical compounds he gave so many examples of the law of definite proportions that the world of chemistry could no longer doubt its validity and in so doing he gave experimental evidence to the atomic theory. He hereby laid a solid fundation for the further development of chemistry. A reprint is found in Ostwald's Klassiker der exakten Wissenschaften No. 35.<br><br>According to S�derbaum Jac. Berzelius 2 p.12 "It was a giant work one of the most importent in the history of chemistry which was here presented. One is even more impressed when one remembers that it was a pioneer undertaking in every sense of the term. Analytic and synthetic methods existed before Berzelius' time to be sure but there were no precise methods of the sort which he required. They all had to be elaborated at the cost of time and labour."J. Erik Jorpes "Jac. Berzelius" p.45.<br><br>"In general Berzelius's efforts were directed toward the consolidation and extension of the atomic theory. He improved chemical analysis and determined the composition of a large number of compounds thus verifying the laws of constant and multiple proportions and furnishing the most accurate equivalent weights then available. By ingenious methods he arrived at the correct atomic composition of most common substances and thus was enabled to draw up in 1826 a table of atomic weights very nearly identical with the modern one."Leicester & Klicktein "A Source Book in Chemistry" p. 258.<br><br>Parkinson "Breakthroughs" 1810-20 C. unknown‎
