Women Scientists: Reflections, Challenges, and Breaking Boundaries
by Research Professor Magdolna Hargittai
Over the past half-century, studies of the evolution of life have themselves evolved, markedly. Life’s earliest history, unknown and thought unknowable for the 100 years following publication of Darwin’s great opus in 1859 has finally come to light as the documented fossil record has been extended an astonishing sevenfold, from 500 million to now 3,500 million years. No longer are studies of evolution based solely on ancient fossils, now augmented by the evidence of life’s long development encod...

The Great Case of Liberty of Conscience Once More Briefly Debated and Defended
by William Penn
The first thing children ask about sex is typically, "Where do babies come from?" This, the most perplexing scientific question of all time, was hailed by the ancient Greeks as "the mystery of mysteries". Throughout history the most intelligent and well-educated men and women have struggled to understand how we reproduce, and the full picture is far from complete. In the mid-17th century, a theory of reproduction - preformation - sparked an intensely heated debate that continued for over 100 yea...
Annual Report of the Trustees of the State Museum of Natural History for the Year ..; 41st (1887)
In 1858, aged thirty-five, weak with malaria, isolated in the remote Spice Islands, Alfred Russel Wallace wrote to Charles Darwin: he had, he said excitedly, worked out a theory of natural selection. Darwin was aghast - his work of decades was about to be scooped. Within a fortnight, his outline and Wallace's paper were presented jointly in London. A year later, with Wallace still at the opposite side of the world, On the Origin of Species was published. Wallace had none of Darwin's advantages o...
Письма и донесения иезуитов о России концk
by А. Ф. Бычков
Here is presented for the first time a comprehensive review and analysis of the several roles played by idealization procedures in the logic, mathematics and models that lie at the heart of modern, twentieth century physics. It is only through idealization of one form or another that the objects and processes of modern physics become tractable. The essays in this volume will be of interest to all those who are concerned with the uses of models in physics, and the relationships between models and...
Записки о императрице Екатерине Великой п
by А. М. Грибовский
Enormous skyscrapers will house residents and workers who happily go "for weeks" without setting foot on the ground. Streamlined, "hurricane-proof" houses will pivot on their foundations like weather vanes. The family car will turn into an airplane so easily that "a woman can do it in five minutes." Our wars will be fought by robots. And our living room furniture-waterproof, of course-will clean up with a squirt from the garden hose. In Yesterday's Tomorrows Joseph J. Corn and Brian Horrigan ex...
Negotiating Knowledge in Early Modern Empires (Palgrave Studies in Cultural and Intellectual History)
by Laszlo Kontler
The contributions to this volume are united by a common interest in the practices that shaped 'science' in the early modern period, with a special emphasis on the ones bred by the emulation, competition, and conflict that encounters across the globe between different cultural and political entities generated. What it attempts is not simply another contribution to the relatively recent but already respectable tradition of 'science and empire.' Rather than adding further nuance to our understandin...
