Almost two centuries had elapsed after Wohler s historical comment cited in his letter to Berzelius in the year 1835 on the ongoing development of organic chemistry his monstrous and boundless thickef is now sufficiently more dense and complex than ever and quite forbidding to strangers Natural products chemistry, a vital section of organic chemistry,... [Pg.2]

It is curious how people working in different disciplines seek and see validation in different kinds of experiments. Only the liquid helium up-the-walls measurement, described in the preceding subsection, seems to satisfy most people that the Lifshitz theory quantitatively accounts for measured forces (see note 37 in the preceding subsection). As with the historical comments, this review of measurements is not intended to be exhaustive.39... [Pg.30]

Hamad I would like to make a historical comment about modularity. Historically, the mother of all modules is Chomsky s autonomy of syntax . That is where it started. It wasn t one of the criteria for modularity. The only criterion that was needed was its functional autonomy— the fact that it could be treated in MIT linguistics by MIT linguists without having to worry about memory, storage capacity, speed and so on. It could be understood on its own terms. This is the only non-arbitrary criterion for modularity that there is the rest of it is things we ve tacked on. [Pg.114]

There is a general agreement that accurate quantum studies on hydrogen bonds require flexible basis sets, i.e., triple- with at least one set of diffuse and polarization functions (especially on H atoms it is surprisingly frequent to find in the literature calculations that exclude these functions from hydrogens) and treatment of electron correlation by means of either wave function-based or DFT-based methods [34-41]. Since these requirements have rendered useless much of the outdated theoretical material published before 1990, one can consider that the efforts to characterize hydrogen bonding from a quantum viewpoint are more or less 15 years old (see the historical comments in Ref. 5). [Pg.111]

The Kirkwood-Buff (KB) theory is the most important theory of solutions. This chapter is therefore central to the entire book. We devote this chapter to derive the main results of this theory. We start with some general historical comments. Then we derive the main results, almost exactly as Kirkwood and Buff did, only more slowly and in more detail, adding occasionally a comment of clarification that was missing in the original publication. We first derive the results for any multicomponent system, and thereafter specialize to the case of two-components system. In section 4, we present the inversion of the KB theory, which has turned a potentially useful theory into an actually useful, general and powerful tool for investigating solutions on a molecular level. Three-component systems and some comments on the application of the KB theory to electrolyte solutions are discussed in the last sections. [Pg.112]

These words were read by Sir Joseph Banks, President of the Royal Society in London in mid-April, 1800. They constitute the opening sentence of Alessandro Volta s letter, despatched from Como on 20 March, 1800. I chose to open this lecture with these historical comments because, like others here this evening, I rejoice in being in Como, the birthplace of Plinius the Elder and Plinius the Younger, and also the place where Alessandro Volta was bom and where he died. In common with millions of scientists world-wide, I have revered the memory of Volta ever since I first heard of his work. That reverence was enhanced when, nearly twenty years ago, my dear fnend, the late Massimo Simonetta, with whom I had an exciting collaboration up until he passed... [Pg.1]

A few short historical comments may clarify the sitnation. One should recall that the notion of isospectral systems originated in physics with the question Can one hear the shape of a drum which was the title of a paper by Mark Kac [74] in 1966 in the American Mathematical Monthly of the Mathematical Association of America. Kac had been invited to submit an article that bronght interesting mathematical... [Pg.82]

If this reconstruction is correct it has far-reaching implications for the formation of the two versions of the Isaiah narratives in 2 Kgs 18-19 and Isa 36-37, and the relationship between them. It definitively proves that the oldest literary core of the Isaiah narrative (version Bi) is in fact itself an addition or Fortschreibung of the tribute episode A in the context of the books of Kings. The Isaiah narrative Bi (2 Kgs i8 i7-i9 9a) can be placed between the tribute episode (2 Kgs 18 13-16) and the historical comment on Sennacherib s withdrawal (2 Kgs 19 36-37) and, with the spirit of God which whispers the news of Tirhakah s attack to the Assyrian king, gives a new cause for the withdrawal. [Pg.157]
