Download and read online ebook Archimedes, the Center of Gravity, and the First Law of Mechanics write by André Koch Torres Assis. This book was released on 2008. Archimedes, the Center of Gravity, and the First Law of Mechanics available in PDF, EPUB and Kindle. Archimedes, the Center of Gravity, and the First Law of Mechanics deals with the most fundamental aspects of physics. The book describes the main events in the life of Archimedes and the content of his works. It goes on to discuss a large number of experiments relating to the equilibrium of suspended bodies under the influence of Earth's gravitational force. All experiments are clearly described and performed with simple, inexpensive materials. These experiments lead to a clear conceptual definition of the center of gravity of material bodies and illustrate practical procedures for locating it precisely. The conditions of stable, neutral, and unstable equilibrium are analyzed. Many equilibrium toys and games are described and explained. Historical aspects of the concept are presented, together with the theoretical values of center of gravity obtained by Archimedes. The book also explains how to build and calibrate precise balances and levers. Several experiments are performed leading to a mathematical definition of the center of gravity and the first law of mechanics, also called the law of the lever. Consequences of this law and different explanations of it are described at the end of the book, together with an exhaustive analysis of the works of Euclid and Archimedes.

Download and read online ebook The Butterflies of Venezuela: Nymphalidae I (Limenitidinae, Apaturinae, Charaxinae) write by Andrew F. E. Neild. This book was released on 1996. The Butterflies of Venezuela: Nymphalidae I (Limenitidinae, Apaturinae, Charaxinae) available in PDF, EPUB and Kindle. Part 1 of The Butterflies of Venezuela was a pioneering work of its kind for South America, being the first authoritative volume in a comprehensive faunistic identification series. The series will prove invaluable to all who wish to learn about the remarkable and diverse butterfly fauna of this country and continent. Approximately 1000 species of adult Nympbalidae, Papilionidae, and Pieridae will be treated in the four-part series, equivalent to over one-third of the total Neotropical species in these families. Drawing on over 20 years of personal research in the field, in collections, and in libraries, the detailed accounts for each species encapsulate all that is known about their identification, distribution, behaviour, habitat, and foodplants. The text, which has been written to appeal to specialists and amateurs alike, has been collated from a wealth of published and unpublished sources. It includes extensive commentary on the systematics and nomenclature employed, and provides detailed notes designed to permit the easy identification of every Venezuelan butterfly. General notes on early stages are provided in the introduction to each genus, and where available those of one representative species are fully described. Readers also benefit from the inclusion of an extensive bibliography, which in Part 2 alone comprises almost 800 works fully referenced in the text. Unlike many other guides, the photographic colour plates illustrate every subspecies, generally showing both sexes and wing surfaces for each, plus several representative specimens for highly variable taxa. In addition, a large number of type specimens are reproduced, many of them for the first time. Part 1 cover 276 species including 2 new species and 23 new subspecies. Part 2 treats 196 species incl. 355 subspecies and the colour plates figures over 450 type specimens. 8 new species and 95 new spubspecies are described. 4 neotypes and 10 lectopypes are designated. Part 3 is projected to treat the Papilionidae, Brassolinae, Danainae, and first part of Satyrinae (Pronophilina and Erebiina). Part 4 will cover the family Pieridae and the remaining Satyrinae and Heliconiinae.
