An historical overview

At the other extreme, the neutrinos and gamma rays emitted by a supernova in 1987 brought brilliant confirmation of the most elaborate theoretical speculations concerning the mechanisms of stellar explosion and the gravitational collapse which immediately precedes it. [Pg.3]

Over a period of forty years, the theory of stellar nucleosynthesis has been transformed from an abstract description of the various nuclear processes that fashion matter to a fully evolved discipline, quite able to stand up to confrontation with a vast body of observational data. [Pg.3]

The futnre is likely to be no less rewarding. Astronomers have not let success go to their heads and their thirst for discovery and knowledge has remained intact. They are certainly not so naive as to believe that the stars have delivered up all their secrets. The most ancient stars, those born before the Galaxy had assumed its present form, have now become a subject of intense interest. The next goal on the distant horizon is a complete picture of chemical evolution in space. In this context, it is quite clear that the early stages of this evolution are the least well understood. The end of the road is not yet in sight. [Pg.3]

No indeed The stars are not made from some incorruptible ether but of ordinary matter. The last post had sounded for the quintessence, the fifth and highest of the elements, along with earth, air, fire and water. Tycho enlisted the services of Kepler and in 1604 master and pupil were rewarded by the magnificent spectacle of a supernova. [Pg.4]

The telescope had not yet appeared. This invention would have to wait for Galileo to arrive on the scene. In 1610, pointing his newly created instrument towards the Moon, Galileo saw mountains. From this, he inferred that it was Earth-like. Today, we would be more inclined to say that the Earth is celestial, as I myself like to reiterate from one book to the next, for I find the fact so startling. At this moment, the distinction between the sublunary sphere, seat of transformation and death, and the superlunary sphere, eternal and perfect, was forever erased. And once the Earth was recognised to be celestial, the sky became mortal and comprehensible. [Pg.4]


A discussion of the motivation behind doing sputtered neutral analysis versus SIMS, plus a description of the first prototype SALI instrument. A well written introduction for someone without previous surface analysis experience it also includes an historical overview of the various post-ionization techniques. [Pg.569]

In this chapter, we describe some of the more widely used and successful kinetic techniques involving controlled hydrodynamics. We briefly discuss the nature of mass transport associated with each method, and assess the attributes and drawbacks. While the application of hydrodynamic methods to liquid liquid interfaces has largely involved the study of spontaneous processes, several of these methods can be used to investigate electrochemical processes at polarized ITIES we consider these applications when appropriate. We aim to provide an historical overview of the field, but since some of the older techniques have been reviewed extensively [2,3,13], we emphasize the most recent developments and applications. [Pg.333]

Theoretical studies have been reported for the neutral29 and alkaline30,31 hydrolysis of formamide. A theoretical study of the acid hydrolysis of iV-formylaziridine concluded that both N- and O-protonated pathways compete.32 In an historical overview of tetrahedral intermediates in the reactions of carboxylic acid derivatives with nucleophiles, several citations of amide reactions are included.33... [Pg.56]

The seminal paper by Burbidge, Burbidge, Fowler, Hoyle [166] (hereafter B2FH) laid down the foundations for these processes, and Wallerstein et al. [167] provides an updated review on B2FH. An historical overview and details of how the s-process operates in AGB stars has been reviewed by Meyer [168], Busso et al. [7], and Herwig [1]. The textbooks by Clayton [9] and Lugaro [15] provide excellent discussions of the s-process at a level aimed at graduate students. [Pg.153]

Emulsions are defined as disperse multi-phase systems of immiscible liquids. In simplest terms, they are either oil-in-water (O/W) or water-in-oil (W/O), where the dispersed phase is listed first and exists as discrete droplets within the continuous phase. In some cases, multiple emulsions can be formed, such as water-in-oil-in-water (W/O/W). Both natural and manufactured emulsions have been studied and utilized extensively, especially within the past 200 years, and Lissant has given an historical overview of the subject [106]. [Pg.143]

The term bimetallic was introduced by Sinfelt to account for the fact that a catalyst may contain a muldtude of phases containing the acdve metallic components. Of these many phases, a characteristic is the binary alloy. The term alloy can describe a broad range of situations from well-defined phases or solid solutions to surface alloys in cases where bulk alloys are not thermodynamically favoured but a clearly defined surface local arrangement is obtained. Note that the novel core-shell bimetallic structures are included in this catchall term. An historical overview of the properties of alloys in connection with catalysis has been published by Ponec. At present, a broadly agreed view accepts that alloy components can be chemically recognised and, therefore, supports a somewhat localised interpretation of the alloy nature and properties. Obviously, a delocalised view loses most of its meaning in the case of clusters due to its finite dimensions. [Pg.125]

Eor an historical overview, see Erik J. Ziircher, Turkey (New York I. B. Tau-ris, 2004), pp. 9-90. Historians of the Ottoman Empire use the term Tanz-imat to denote the period between 1839-76. The reformist spirit certainly persists through the reign of Sultan Abdiilhamid II (1876-1909), despite his repressions. [Pg.257]
