Download or read book The Vitamin A Story written by R.D. Semba and published by Karger Medical and Scientific Publishers. This book was released on 2013-07-01 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book shows how vitamin A deficiency – before the vitamin was known to scientists – affected millions of people throughout history. It is a story of sailors and soldiers, penniless mothers, orphaned infants, and young children left susceptible to blindness and fatal infections. We also glimpse the fortunate ones who, with ample vitamin A-rich food, escaped this elusive stalker. Why were people going blind and dying? To unravel this puzzle, scientists around the world competed over the course of a century. Their persistent efforts led to the identification of vitamin A and its essential role in health. As a primary focus of today’s international public health efforts, vitamin A has saved hundreds of thousands of lives. But, we discover, they could save many more were it not for obstacles erected by political and ideological zealots who lack a historical perspective of the problem. Although exhaustively researched and documented, this book is written for intellectually curious lay readers as well as for specialists. Public health professionals, nutritionists, and historians of science and medicine have much to learn from this book about the cultural and scientific origins of their disciplines. Likewise, readers interested in military and cultural history will learn about the interaction of health, society, science, and politics. The author’s presentation of vitamin A deficiency is likely to become a classic case study of health disparities in the past as well as the present.

Download or read book Epistemology of Experimental Gravity Scientific Rationality written by Nicolae Sfetcu and published by MultiMedia Publishing. This book was released on with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolution of gravitational tests from an epistemological perspective framed in the concept of rational reconstruction of Imre Lakatos, based on his methodology of research programmes. Unlike other works on the same subject, the evaluated period is very extensive, starting with Newton's natural philosophy and up to the quantum gravity theories of today. In order to explain in a more rational way the complex evolution of the gravity concept of the last century, I propose a natural extension of the methodology of the research programmes of Lakatos that I then use during the paper. I believe that this approach offers a new perspective on how evolved over time the concept of gravity and the methods of testing each theory of gravity, through observations and experiments. I argue, based on the methodology of the research programmes and the studies of scientists and philosophers, that the current theories of quantum gravity are degenerative, due to the lack of experimental evidence over a long period of time and of self-immunization against the possibility of falsification. Moreover, a methodological current is being developed that assigns a secondary, unimportant role to verification through observations and/or experiments. For this reason, it will not be possible to have a complete theory of quantum gravity in its current form, which to include to the limit the general relativity, since physical theories have always been adjusted, during their evolution, based on observational or experimental tests, and verified by the predictions made. Also, contrary to a widespread opinion and current active programs regarding the unification of all the fundamental forces of physics in a single final theory, based on string theory, I argue that this unification is generally unlikely, and it is not possible anyway for a unification to be developed based on current theories of quantum gravity, including string theory. In addition, I support the views of some scientists and philosophers that currently too much resources are being consumed on the idea of developing quantum gravity theories, and in particular string theory, to include general relativity and to unify gravity with other forces, as long as science does not impose such research programs.

Download or read book Heritage Sites of Astronomy and Archaeoastronomy in the Context of the UNESCO World Heritage Convention written by Clive L. N. Ruggles and published by . This book was released on 2017-11-30 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This joint venture between ICOMOS, the advisory body to UNESCO on cultural sites, and the International Astronomical Union is the second volume in an ongoing exploration of themes and issues relating to astronomical heritage in particular and to science and technology heritage in general. It examines a number of key questions relating to astronomical heritage sites and their potential recognition as World Heritage, attempting to identify what might constitute "outstanding universal value" in relation to astronomy. "Heritage Sites of Astronomy and Archaeoastronomy--Volume 2" represents the culmination of several years' work to address some of the most challenging issues raised in the first ICOMOS-IAU Thematic Study, published in 2010. These include the recognition and preservation of the value of dark skies at both cultural and natural sites and landscapes; balancing archaeoastronomical considerations in the context of broader archaeological and cultural values; the potential for serial nominations; and management issues such as preserving the integrity of astronomical sightlines through the landscape.Its case studies are developed in greater depth than those in volume 1, and generally structured as segments of draft nomination dossiers. They include seven-stone antas (prehistoric dolmens) in Portugal and Spain, the thirteen towers of Chankillo in Peru, the astronomical timing of irrigation in Oman, Pic du Midi de Bigorre Observatory in France, Baikonur Cosmodrome in Kazakhstan, and Aoraki-Mackenzie International Dark Sky Reserve in New Zealand. A case study on Stonehenge, already a World Heritage Site, focuses on preserving the integrity of the solstitial sightlines.As for the first ICOMOS-IAU Thematic Study, a international team of authors including historians, astronomers and heritage professionals is led by Professor Clive Ruggles for the IAU and Professor Michel Cotte for ICOMOS.

Available in PDF, EPUB and Kindle. Book excerpt: At the time of ?nalising this second volume of the ?Yearbook on Space Policy? which covers the period mid-2007 to mid-2008, Europe is as visible and strong in the area of space activities as never before. Its space probes are present on the Moon, around Mars, and on Saturn?s Moon Titan, and are chasing asteroids and comets; Ariane V is the most successful commercial launch vehicle; and more and more European space applications satellites are in operation. Finally, with the successful launch of the Columbus Orbital Facility (COF) – the most prominent highlight of this period which is also depicted on the cover of this Yearbook – and the ?rst Automated Transfer Vehicle (ATV), Europe has become a decisive player in human space?ight. This is accompanied by new policy initiatives on the ministerial level which have been bringing the European Space Agency and the European Union steadily closer. Europe?s outstanding development and positioning in the space ?eld is based not only on Europe?s successful engineering and scienti?c capabilities and capacities, but also on the forceful political determination of all European actors to maintain and even further their engagement in the use of outer space. And it is this political determination which provides the focus for this ?Yearbook on Space Policy?. The Yearbook describes and analyses the contexts and contents of space policy. Its primary ?eld of investigation is Europe, but it also covers the whole range of global space activities and their in?uence on European endeavours.

Download or read book Eternity by the Stars written by Louis-Auguste Blanqui and published by . This book was released on 2013-05 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a century replete with radical politics, final liberations, historical codas, and dreams of eternity, the shadowy figure of Louis-Auguste Blanqui, the constant revolutionary, wrote Eternity by the Stars in the last months of 1871 while incarcerated in Fort du Taureau, a marine cell of the English Channel. In the midst of contemplating his confinement, Blanqui devises a simple calculation in which the infinity of time is confronted with the finite number of possible events to suggest a most radical conclusion: every chain of events is bound to repeat itself eternally in space and time. Our lives are being lived an infinity of times across the confines of the universe, and death, defeat, success and glory are never final. For the world is nothing but the play of probabilities on the great stage of time and space. By straddling the boundaries of hyperrealism and hallucinatory thinking, Blanqui's hypothesis offers a deep, tragic, and heartfelt reflection on the place of the human in the universe, the value of action, and the aching that lies at the heart of every modern soul. This first critical edition of Blanqui's incantatory text in English features an extended introduction by Frank Chouraqui. Exploring sources of Blanqui's thinking in his intellectual context, Chouraqui traces the legacy of the text in critiques of modernity devoting particular attention to the figures of Nietzsche, Walter Benjamin, and Borges. It features copious illuminating annotations that bring out the web of connections which interlace the great marginal figure of Blanqui with more than two millennia of European culture.

Download or read book Bode s Law and the Discovery of Juno written by Clifford J. Cunningham and published by Springer. This book was released on 2017-06-02 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Johann Bode developed a so-called law of planetary distances best known as Bode’s Law. The story of the discovery of Juno in 1804 by Karl Harding tells how Juno fit into that scheme and is examined as it relates to the philosopher Georg Hegel’s 1801 thesis that there could be no planets between Mars and Jupiter. By 1804 that gap was not only filled but had three residents: Ceres, Pallas and Juno! When Juno was discovered no one could have imagined its study would call into question Newton’s law of gravity, or be the impetus for developing the mathematics of the fast Fourier transform by Carl Gauss. Clifford Cunningham, a dedicated scholar, opens to scrutiny this critical moment of astronomical discovery, continuing the story of asteroid begun in earlier volumes of this series. The fascinating issues raised by the discovery of Juno take us on an extraordinary journey. The revelation of the existence of this new class of celestial bodies transformed our understanding of the Solar System, the implications of which are thoroughly discussed in terms of Romantic Era science, philosophy, poetry, mathematics and astronomy. The account given here is based on both English and foreign correspondence and scientific papers, most of which are translated for the first time.

Download or read book The Arabic Hermes written by Kevin van Bladel and published by Oxford University Press. This book was released on 2009-08-26 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first major study devoted to the early Arabic reception and adaption of the figure of Hermes Trismegistus, the legendary Egyptian sage to whom were ascribed numerous works on astrology, alchemy, talismans, medicine, and philosophy. Before the more famous Renaissance European reception of the ancient Greek Hermetica, the Arabic tradition about Hermes and the works under his name had been developing and flourishing for seven hundred years. The legendary Egyptian Hermes Trismegistus was renowned in Roman antiquity as an ancient sage whose teachings were represented in books of philosophy and occult science. The works in his name, written in Greek by Egyptians living under Roman rule, subsequently circulated in many languages and regions of the Roman and Sasanian Persian empires. After the rise of Arabic as a prestigious language of scholarship in the eighth century, accounts of Hermes identity and Hermetic texts were translated into Arabic along with the hundreds of other works translated from Greek, Middle Persian, and other literary languages of antiquity. Hermetica were in fact among the earliest translations into Arabic, appearing already in the eighth century. This book explains the origins of the Arabic myth of Hermes Trismegistus, its sources, the reasons for its peculiar character, and its varied significance for the traditions of Hermetica in Asia and northern Africa as well as Europe. It shows who pre-modern Arabic scholars thought Hermes was and how they came to that view.
