Bøger i Source Books in the History of the Sciences serien

Here, find source literature for the most important contributions to the remarkable recent expansion of geological knowledge. Excerpted are 65 articles on topics including the constitution of Earth¿s interior, earthquakes, radioactive timekeepers, submarine features and deep-sea cores, entrapment of petroleum, and crystal structure.

The two main aims of this book are to increase the general availability of classical contributions to animal biology and to present the development of thought in this field in the words of those who produced it.

No detailed description available for "A Source Book in Geology, 1400-1900".

The Source Book serves as an introduction to present-day chemistry and can also be used as supplementary reading in general chemistry courses, since, in many instances, the papers explain the circumstances under which a particular discovery was made--information that is customarily lacking in textbooks. Although the selections are classified into the usual branches of the science, it will be apparent to the reader how the discoveries in any one branch were taken up and incorporated into others.

In this volume readers can rediscover A.S. Eddington's elegant proof of the virial theorem for star clusters, Walter Baade and Fritz Zwicky's 1932 proposal for the existence of neutron stars, and Thomas Gold's forecast of collapsed stars as radio sources. They can reread, in the words of the canyons, pulsars, interstellar hydrogen cosmic magnetic fields, quasars, and remnant background radiation of the primeval big bang.

Gathered together here are the fundamental texts of the great classical period in modern logic. A complete translation of Gottlob Frege's Begriffsschrift-which opened a great epoch in the history of logic by fully presenting propositional calculus and quantification theory-begins the volume, which concludes with papers by Herbrand and by Goedel.
