Book Description
This collection of essays in organised into two parts. Part one considers the economic challenges in the context of globalisation; part two, information and education challenges. The papers on economic challenges critique the co-existence of traditional models of state management of the economy and economic nationalism, with neo-liberal globalisation/internationalism. They pose the argument that global management of economies will necessarily disfavour pour countries, and that Africa requires a mixture of economic nationalism and entrepreneurial states in order to progress. The second part of the work expands this proposition setting out how African countries must harness communication technologies to share knowledge, achieve cultural and economic solidarity, and avoid periods of financial instability and economic crashes. A final paper considers whether a linguistic renaissance in Africa is a prerequisite for a wider cultural and economic renaissance, and proposes policies - such as some education in the mother tongue - that might be adopted to increase the prominence and status of African languages.

A collection of useful articles.......2001-05-14
This is not exactly bed-time reading (I tried), but many of the articles are well written. Most of them contain useful stuff and I hope to get around to implementing and testing some of the ideas. If you are interested in computational aspects of Comparative Genomics, then this book is a must.

Description:
A simple, sensitive, selective, precise and stability indicating high-performance thin-layer chromatographic method for determination of gatifloxacin both as a bulk drug and from polymeric nanoparticles was developed and validated as per the International Conference on Harmonization (ICH) guidelines. The method employed thin-layer chromatography (TLC) aluminium plates precoated with silica gel 60F-254 as the stationary phase and the mobile phase consisted of n-propanol-methanol-concentrated ammonia solution (25%) (5:1:0.9, v/v/v). This solvent system was found to give compact spots for gatifloxacin (R"f value of 0.60+/-0.02). Densitometric analysis of gatifloxacin was carried out in the absorbance mode at 292nm. The linear regression analysis data for the calibration plots showed good linear relationship with r=0.9953 with respect to peak area in the concentration range of 400-1200ngspot^-^1. The mean value (+/-S.D.) of slope and intercept were 9.66+/-0.05 and 956.33+/-27.67, respectively. The method was validated for precision, accuracy, ruggedness and recovery. The limits of detection and quantitation were 2.73 and 8.27ngspot^-^1, respectively. Gatifloxacin was subjected to acid and alkali hydrolysis, oxidation, photodegradation and dry heat treatment. The drug undergoes degradation under acidic and basic conditions and upon wet and dry heat treatment. The degraded products were well separated from the pure drug. The statistical analysis proves that the developed method for quantification of gatifloxacin as bulk drug and from polymeric nanoparticles is reproducible and selective. As the method could effectively separate the drug from its degradation products, it can be employed as stability-indicating one.

Born in Austria and something of a bumpkin by nature, the 19th-century physicist Ludwig Boltzmann did not fit in easily in the highly cultured German universities at which he taught for many years. To add to his difficulties, Boltzmann stirred up controversy by proposing that scientists could make intelligent guesses about the behavior of atoms, which, though they moved randomly, could be described by certain probabilistic generalizations. His suggestion, hinging on novel interpretations of statistical theory, was not immediately acclaimed. "To an audience of physicists raised in the belief that scientific laws ought to encapsulate absolute certainties and unerring rules," writes scientist and journalist David Lindley, "these were profound and disturbing changes."
Opposed by the then-influential physicist and philosopher Ernst Mach, who urged that scientists stick to classical thermodynamics, Boltzmann was hard-pressed to convince his colleagues that the behavior of atoms could be explained by laws thought to apply only to the gaming table. Mach objected, and with some cause, that "the fact that the theory worked was not enough to prove that the assumptions on which the theory rested were true." It would take the next generation of scientists, among them Albert Einstein, to provide more solid proof for Boltzmann's hunches. And, while Mach's contributions to physics have largely been superseded, Boltzmann's endure in quantum mechanics and the Maxwell-Boltzmann distribution for the velocities of atoms in a gas. In this lively account, David Lindley tells the story of Boltzmann's many failures, and of his eventual success. --Gregory McNamee
Book Description
BOLTZMANN'S ATOM tells the story of the crucial scientific struggle over the existence of the atom during the second half of the 19th century. This struggle was a turning point in the history of the modern world. It would never have happened without the forgotten genius of Ludwig Boltzmann, a 19th century Austrian theoretical physicist who had a string of deeply profound insights primarily into the physical nature of heat, but also gas, matter, and, in fact, literally everything. In 1850 no university taught such a subject as theoretical physics, but by 1900 it was a fully fledged discipline with whole institutes devoted to it. This burgeoning scientific movement led within just a few years to the discovery of quantum mechanics by Max Planck, radioactivity by Marie Curie, general relativity by Albert Einstein, the uncertainty principle by Werner Heisenberg, and more recently quantum electodynamics by Richard Feynman, the quark by Murray Gell-Mann, and even up-to-the minute developments in chaos and superstring theory. Indeed, as David Lindley shows, Boltzman's brilliant insights brought about the golden age of physics that we continue to live in today. David Lindley frames his story with the long running debate between Boltzmann and Ernst Mach who held that theoretical physics was completely misguided. Mach's memorable line in 1900 "I don't believe atoms exist" is where the book begins.

The harrowing fight for Boltzmann's atom.......2007-10-04
Lindley states upfront that this book is not a proper biography. There is not much on Boltzmann's early life, and the account of his adult family life is very sketchy. Actually, I found this an advantage as I was most interested in the development of Boltzmann's physics and how Boltzmann related to other famous figures. Lindley is very good on this, showing exactly what Boltzmann's contributions were and how figures like Gibbs and Maxwell inspired him and were inspired by him. The accounts of his philosophical battle with Mach for the soul of physics were particularly intriguing - a battle that ended in Boltzmann's suicide. Mach had won the battle, but not the war. Einstein and others later came down on Boltzmann's side.
Of course Mach can't really be blamed for Boltzmann's suicide. Boltzmann comes across as a depressive, neurotic character. He could not relax, was forever traveling, and incessantly pursued social and academic advancement. When given the leading post at the University of Vienna he sought posts at German universities, but then didn't want to leave Vienna when he got them. This 'having his cake and eating it' situation left him distraught, torn between two great opportunities. Also, he became upset when followers of Mach did not admire him, even though his own followers held him in the greatest esteem.
It is surprising how much physics Lindley manages to convey without using equations. Differences between his ideas and others are conveyed with subtlety. For instance the difference between using a distribution of velocities and the earlier idea of just using average velocities for working out the statistical mechanics of gasses is brought across with verve. (Read the book if you don't know what I'm going on about!)
Lindley makes impressive use of original sources. You will find material in this book nowhere else in English as he translates many letters and works from the original German.
All in all, a must read. There are many popular books centered on Galileo, Newton, Einstein and Heisenberg. It is interesting to read a book where these giants hardly figure, and instead Boltzmann, Gibbs, Maxwell and Mach take center stage. So give yourself a novel treat and read about the harrowing fight for Boltzmann's atom.
good introduction.......2007-07-06
David Lindley succeeds in this book in what escaped him in "Uncertainty: Einstein, Heisenberg, Bohr, and the Struggle for the Soul of Science", where the narrative lacks structure and is not sufficiently persuasive. "Boltzmann's Atom" reads as a biography proper, if a very brief one, where Lindley shows (appropriately) broader historical picture, not just in scientific and philosophical ideas of that time.
Boltzmann is shown in this book as a real human being - in development, both intellectual and emotional - and one can actually empathize with him. The book is somewhat too short for a real biography, which all run nowadays to 500 and more pages, but especially so considering the scope of Boltzman's personality, as well as very complex & rapidly changing situation in science during his lifetime. Still, the book is a very good introduction to Boltzman's life & work.
Even in this short a book, Lindley managed to outline Boltzmann's scientific & philosophical ideas, show clearly what was his conflict with Ernst Mach about, and give the reader enough understanding to see that modern physics is based to a high degree on Boltzmann's works. Lindley also succeeded in giving a persuasive picture of Boltzmann's idiosyncratic personality.
Hope David Lindley won't consider a short quote from his book to be a copyright violation: http://docs.google.com/View?docid=dhcsjrmw_192cpz88x&revision=_latest
scientists are people, too.......2006-05-04
David Lindley's book is a beautifully written and subtle portrait not only of a very important scientist, but of a place and time in scientific history. Some rather slippery scientific concepts are expertly communicated at the same time -- that Lindley manages to do all of this in the space of about 230 pages makes this book a model, in my mind, of concision and expert communication. It is a joy to read.
If anything mitigates that joy, it is the intense sadness that hangs around the titular figure, Ludwig Boltzmann. Although his work is of primary importance in physics, few laypeople are aware of him. Boltzmann died in 1906 but -- much like his fellow Viennese Gustav Mahler, who died in 1911 -- seems like a kind of presage of 20th century uncertainties and anxieties. This is probably saying too much. But there is little of the heroic and the ironic and the certain in Boltzmann, and much of the anxious, needy and depressed. He is a figure we all recognize: whether in our alcoholic uncles, our desperate mothers, or our sleepless selves. He does not and cannot rest easy.
Boltzmann was far from anyone's stereotype of the "mad" scientist. His mental illness was all too real, his struggle with inner demons all too tragic. If you are interested in science, in scientists, in the occasionally sick world of academia, or even simply in fin-de-siecle Vienna, read this book. It's extremely good.
Father of Atomic theory.......2006-04-10
The scientific community of the late 19th century were scandalised when Boltzmann introduced his Atomic theory. First his attribution of probability, and using statistical methods to explain thermodynamics went against the longstanding trend of assuming absolute fixed laws. In comparison the implication of probability in Quantum theory, caused bewilderment rather than stringent criticism of the theory. Second, due to lack of observable evidence, atoms were considered a figment of Boltzmanns imagination. This is not very dissimilar to the opposition faced by String Theory proponents even today who have no way of confirming existence of Strings.
It was not until Einstein used Atomic theory to prove Brownian Motion that people began to consider it seriously.
Boltzmann got one more hunch right . In 1905, touring Berkeley , he notes 'Happy the land where Millionaires hold ideals and idealists become millionaires'. Though bitter about its food, and worker strikes, he concludes 'America will accomplish great things in the future. I believe in these people'
Couldv been 50 pages short atleast.
Excellent Read!.......2005-09-23
I loved this book. I was very wrapped up in it throughout. I highly recommend it to any physics students who are about to undertake a course in Thermo or Stat Mech. Amazingly, Lindley does a better job of explaining some things than many textbooks. I learned a lot from this book. I think seeing the historical development aides in learning the science.
One downside is the lack of more in-depth science. Only one equation is written (S=klnw). It would be nice to see more of the physics being developled...possibly an idea for a new textbook...
All in all, very fun. I would love to read more history of physics books that are written similarly.

A wonderful tale on simple love of nature.......2007-08-01
This is a magic tale about a simple shepard who loved his land and decided to make it a better place. Quietly, humbly, constantly. I am planning to read this to my kids. I hope it will make them love nature -and trees in particular- as much as I do...
This Book is Cool.......2004-02-06
For anyone with a little understanding of French, this book is for you. The themes and illustration really bring out the story. I loved it and you will too.

Decent translation, but not well-sourced.......2005-08-20
While I agree with other reviewers that this is a better translation than Cleaves, it is not very well-sourced. Onon makes many assertions based on "I know this because I am a Mongol" which are not, as far as I can tell, supportable. I would recommend Onon for his readability, but the two-volume Igor De Rachewiltz translation has far better annotations and commentary for scholarly purposes. Onon's assertions (especially about Buddhism in the Mongol Empire) should probably be taken with numerous grains of salt.
Neither translation is particularly affordable for the average person, which is why we have interlibrary-loan.
Must have book........2003-12-09
Interested in Mongols' History? Think you know Chinggis khaan (Genghis Khan)? If you haven't read this book gotta have this one then. Without it you don't know a thing about Chinggis khaan. There are lots of translations of "The Secret History of the Mongols." But this. This is the best translation work! Urgunge Onon's translation is incomparable with other translations.
Wonderful translation -- much more accurate than Cleaves.......2002-10-22
This is an excellent translation of the Mongoliin Nuuts Tovchoo (Secret History of the Mongols). It is much more accurate that the Francis Cleaves edition. Onon fixes Cleaves' mistakes and explains why they are wrong. There are also good explanations of the mistakes of many of the Chinese interlinear notes in the early manuscript. Besides the outrageous price, this book is a "must have!"
Book Description
Contains learning objectives, chapter outlines (with space for students' notes on particular sections), key-term identifications, short answer and essay questions, map exercises, and "comparison charts" which help students organize the information about different cultures and events discussed in each chapter.

This book has caused me great suffering........2003-03-10
I am a sophomore in highschool taking an AP class with this book. It has a lot of information, which I guess is a good thing if you are reading this for your own personal gain rather than being tested on it. However, it is so dense that it is difficult to pick up key ideas. Every piece of information is important on some level, and the tests I take, which my teacher got along with this book, also treat every fact as important. I wouldn't mind reading this book if I wasn't expected to have a photographic memory but it just doesn't do a good job of helping me understand key ideas in history. Well, if you have to read this in your history class I hope you have a good teacher to guide you along in the reading. Otherwise.... I hope your memory is better than mine!!
The earth and its people: a global history.......2001-03-05
Excellent book for senior high school-college-undergraduate studies, covering the broad field of world history. The text is structured in such a manner as to suit both brief studies of various areas and times, as well as more in depth, long term programs. A fascinating assortment of primary source excerpts have been included, from earliest human societies to issues facing humanity in the contemporary period. Though the text has a slight Western emphasis, it covers non-Western civilisations quite well.
Be prepared though for extensive reading. The complete set is very large, but shouldn't be an obstacle for those with a passion for both general and obscure history!
Product Description
This book explores the history of the world from 1500 to 2001.
Book Description
This book differs from other introductions to pragmatics in approaching the problems of interpreting language use in terms of interpersonal modelling of beliefs and intentions. It is intended to make issues involved in language understanding, such as speech, text, and discourse, accessible to the widest group possible -- not just specialists in linguistics or communication theorists -- but all scholars and researchers whose enterprises depend on having a useful model of how communicative agents understand utterances and expect their own utterances to be understood.
Based on feedback from readers over the past seven years, explanations in every chapter have been improved and updated in this thoroughly revised version of the original text published in 1989. The most extensive revisions concern the relevance of technical notions of mutual and normal belief, and the futility of using the notion 'null context' to describe meaning. In addition, the discussion of implicature now includes an extended explication of "Grice's Cooperative Principle" which attempts to put it in the context of his theory of meaning and rationality, and to preclude misinterpretations which it has suffered over the past 20 years. The revised chapter exploits the notion of normal belief to improve the account of conversational implicature.
Customer Reviews:
Excellent Book.......2006-12-23
Green provides an excellent introduction to a broad range of topics in the field of Pragmatics and does so in lucid, unaffected prose. This book manages to provide a fairly detailed description of numerous phenomena, including indexical and anaphora, the cooperative principle and implicatures, performativity and a great deal more. This is an excellent book for anyone begining to study Pragmatics or for those just interested in a scientific treatment of how language works in everyday life.
