History Of Free Fall

Sammy Mountjoy, artist, rises from poverty and an obscure birth to see his pictures hung in the Tate Gallery. Swept into World War Two, he is taken as a prisoner-of-war, threatened with torture, then locked in a cell of total darkness to wait. He emerges from his cell transfigured from his ordeal, and begins to realise what man can be and what he has gradually made of himself through his own choices. But did those accumulated choices also begin to deprive him of his free will.

From the infinitesimal scale of particle physics to the cosmic scale of the universe, research is concerned with the nature of mass. While there have been spectacular advances in physics during the past century, mass still remains a mysterious entity at the forefront of current research. Our current perspective on gravitation has arisen over millennia, through the contemplation of falling apples, lift thought experiments and notions of stars spiraling into black holes. In this volume, the world’s leading scientists offer a multifaceted approach to mass by giving a concise and introductory presentation based on insights from their respective fields of research on gravity. The main theme is mass and its motion within general relativity and other theories of gravity, particularly for compact bodies. Within this framework, all articles are tied together coherently, covering post-Newtonian and related methods as well as the self-force approach to the analysis of motion in curved space-time, closing with an overview of the historical development and a snapshot on the actual state of the art. All contributions reflect the fundamental role of mass in physics, from issues related to Newton’s laws, to the effect of self-force and radiation reaction within theories of gravitation, to the role of the Higgs boson in modern physics. High-precision measurements are described in detail, modified theories of gravity reproducing experimental data are investigated as alternatives to dark matter, and the fundamental problem of reconciling any theory of gravity with the physics of quantum fields is addressed. Auxiliary chapters set the framework for theoretical contributions within the broader context of experimental physics. The book is based upon the lectures of the CNRS School on Mass held in Orléans, France, in June 2008. All contributions have been anonymously refereed and, with the cooperation of the authors, revised by the editors to ensure overall consistency.

Locked in a desperate Cold War race against the Soviets to find out if humans could survive in space and live through a free fall from space vehicles, the Pentagon gave civilian adventurer Nick Piantanida’s Project Strato-Jump little notice until May Day, 1966. Operating in the shadows of well-funded, high-visibility Air Force and Navy projects, the former truck driver and pet store owner set a new world record for manned balloon altitude. Rising more than 23 miles over the South Dakota prairie, Piantanida nearly perished trying to set the world record for the highest free fall parachute jump from that height. On his next attempt, he would not be so lucky. Part harrowing adventure story, part space history, part psychological portrait of an extraordinary risk-taker, this story fascinates and intrigues the armchair adventurer in all of us.

As enjoyable as it is important, this classic encompasses 30 years of highly original experiments and theories. Its lively, readable expositions discuss dynamics, elasticity, sound, strength of materials, more. 126 diagrams.

Corruption, conspiracy and a cop in trouble - only Cole and Pike can help. Elvis Cole is just a detective who can't say no, especially to a girl in a terrible fix. And Jennifer Sheridan qualifies. Her fiancé, Mark Thurman, is a decorated LA cop with an elite plainclothes unit, but Jennifer is sure he's in trouble - the kind of serious trouble that only Cole can get him out of. Five minutes after his new client leaves the office, Cole and his partner, the enigmatic Joe Pike, are hip-deep in a deadly situation as they plummet into a world of South Central gangs, corrupt cops and conspiracies of silence. And before long, every cop in the LAPD is gunning for a pair of armed and dangerous killers - Cole and Pike.

The question of when and how the basic concepts that characterize modern science arose in Western Europe has long been central to the history of science. This book examines the transition from Renaissance engineering and philosophy of nature to classical mechanics oriented on the central concept of velocity. For this new edition, the authors include a new discussion of the doctrine of proportions, an analysis of the role of traditional statics in the construction of Descartes' impact rules, and go deeper into the debate between Descartes and Hobbes on the explanation of refraction. They also provide significant new material on the early development of Galileo's work on mechanics and the law of fall.
