Duhem's 1908 essay questions the relation between physical theory and metaphysics and, more specifically, between astronomy and physics–an issue still of importance today. He critiques the answers given by Greek thought, Arabic science, medieval Christian scholasticism, and, finally, the astronomers of the Renaissance.

Much of Duhem's work as a professional scientist was closely related to the newly emerging discipline of physical chemistry. The book and associated papers translated here revolve around his concomitant philosophical and historical interests in chemistry-topics largely uncovered by Duhem's writings hitherto available in English. He understood contemporary concerns of chemists to be a development of the ancient dispute over the nature of mixture. Having developed his historical account from...

Here is a multidimensional playland of ideas from the world's most eccentric Nobel-Prize winning scientist. Kary Mullis is legendary for his invention of PCR, which redefined the world of DNA, genetics, and forensic science. He is also a surfer, a veteran of Berkeley in the sixties, and perhaps the only Nobel laureate to describe a possible encounter with aliens. A scientist of boundless curiosity, he refuses to accept any proposition based on secondhand or hearsay evidence, and always loo...

The Periodic Table is one of the most recognizable images in science - and in our culture. Its 118 elements make up everything on our planet and in the entire universe.But how many of us actually know how to interpret its distinctive design? And what does its unique arrangement tell us about the behaviour of each element in the world around us?The Periodic Table looks at the fascinating story and surprising history of each of these...

There are eight columns in the Periodic Table. The eighth column is comprised of the rare gases, so-called because they are the rarest elements on earth. They are also called the inert or noble gases because, like nobility, they do no work. They are colorless, odorless, invisible gases which do not react with anything, and were thought to be unimportant until the early 1960s. Starting in that era, David Fisher has spent roughly fifty years doing research on these gases, publishing nearly a...

Raymond E. Barrett's Build-It-Yourself Science Laboratory is a classic book that took on an audacious task: to show young readers in the 1960s how to build a complete working science lab for chemistry, biology, and physics--and how to perform experiments with those tools. The experiments in this book are fearless and bold by today's standards--any number of the experiments might never be mentioned in a modern book for young readers! Yet, many from previous generations fondly remember how w...

Mechanism of charge transport in organic solids has been an issue of intensive interests and debates for over 50 years, not only because of the applications in printing electronics, but also because of the great challenges in understanding the electronic processes in complex systems. With the fast developments of both electronic structure theory and the computational technology, the dream of predicting the charge mobility is now gradually becoming a reality.This volume describes re...

Over the past decade there has been a resurgence of interest in growing fruit and vegetables in the garden and on the allotment. Part of the driving force behind this is an increased awareness of the health benefits that can be derived from fruit and vegetables in the diet. The 'five helpings a day' dictum reflects the correlation between a regular consumption of fruit and vegetables and a reduced incidence of, for example, cardiovascular disease and some cancers. Growing your own vegetabl...

Philosophy of Chemistry investigates the foundational concepts and methods of chemistry, the science of the nature of substances and their transformations. This groundbreaking collection, the most thorough treatment of the philosophy of chemistry ever published, brings together philosophers, scientists and historians to map out the central topics in the field. The 33 articles address the history of the philosophy of chemistry and the philosophical importance of some central figures in the ...
