Reflections On The Motive Power Of Fire

This is just...entropy, he said, thinking that this explained everything, and he repeated the strange word a few times. 1 ? Karel Capek , “Krakatit” This “strange word” denotes one of the most basic quantities of the physics of heat phenomena, that is, of thermodynamics. Although the concept of entropy did indeed originate in thermodynamics, it later became clear that it was a more universal concept, of fundamental signi?cance for chemistry and biology, as well as physics. Although the concept of energy is usually considered more important and easier to grasp, it turns out, as we shall see, that the idea of entropy is just as substantial—and moreover not all that complicated. We can compute or measure the quantity of energy contained in this sheet of paper, and the same is true of its entropy. Furthermore, entropy has remarkable properties. Our galaxy, the solar system, and the biosphere all take their being from entropy, as a result of its transferenceto the surrounding medium.

All of this is expounded in the present book, thereby conveying informationto the readeranddecreasinghis entropy;butitis uptothe readertodecidehowvaluable this information might be.

An exhilarating reinvention of the gothic novel, inspired by the iconic characters of our greatest myths and nightmares. Hemlock Grove is now a hit television series on Netflix. The body of a young girl is found mangled and murdered in the woods of Hemlock Grove, Pennsylvania, in the shadow of the abandoned Godfrey Steel mill. A manhunt ensues—though the authorities aren't sure if it's a man they should be looking for. Some suspect an escapee from the White Tower, a foreboding biotech facility owned by the Godfrey family—their personal fortune and the local economy having moved on from Pittsburgh steel—where, if rumors are true, biological experiments of the most unethical kind take place. Others turn to Peter Rumancek, a Gypsy trailer-trash kid who has told impressionable high school classmates that he's a werewolf. Or perhaps it's Roman, the son of the late JR Godfrey, who rules the adolescent social scene with the casual arrogance of a cold-blooded aristocrat, his superior status unquestioned despite his decidedly freakish sister, Shelley, whose monstrous medical conditions belie a sweet intelligence, and his otherworldly control freak of a mother, Olivia. At once a riveting mystery and a fascinating revelation of the grotesque and the darkness in us all, Hemlock Grove has the architecture and energy to become a classic in its own right—and Brian McGreevy the talent and ambition to enthrall us for years to come.

The title essay, along with other papers in this volume, laid the foundation of modern thermodynamics. Highly readable, "Reflections" contains no arguments that depend on calculus, examining the relation between heat and work in terms of heat in steam engines, air-engines, and an internal combustion machine. Translation of 1890 edition.
