Download or read book Geniuses at War written by David A. Price and published by Knopf. This book was released on 2021-06-22 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dramatic, untold story of the brilliant team whose feats of innovation and engineering created the world’s first digital electronic computer—decrypting the Nazis’ toughest code, helping bring an end to WWII, and ushering in the information age. Planning the invasion of Normandy, the Allies knew that decoding the communications of the Nazi high command was imperative for its success. But standing in their way was an encryption machine they called Tunny (British English for “tuna”), which was vastly more difficult to crack than the infamous Enigma cipher. To surmount this seemingly impossible challenge, Alan Turing, the Enigma codebreaker, brought in a maverick English working-class engineer named Tommy Flowers who devised the ingenious, daring, and controversial plan to build a machine that would calculate at breathtaking speed and break the code in nearly real time. Together with the pioneering mathematician Max Newman, Flowers and his team produced—against the odds, the clock, and a resistant leadership—Colossus, the world’s first digital electronic computer, the machine that would help bring the war to an end. Drawing upon recently declassified sources, David A. Price’s Geniuses at War tells, for the first time, the full mesmerizing story of the great minds behind Colossus and chronicles the remarkable feats of engineering genius that marked the dawn of the digital age.

This book was released on 2019-05-13 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many women scientists, particularly those who did crucial work in two world wars, have disappeared from history. Until they are written back in, the history of science will continue to remain unbalanced. This book tells the story of Elizabeth Alexander, a pioneering scientist who changed thinking in geology and radio astronomy during WWII and its aftermath.Building on an unpublished diary, recently declassified government records and archive material adding considerably to knowledge about radar developments in the Pacific in WWII, this book also contextualises Elizabeth's academic life in Singapore before the war, and the country's educational and physical reconstruction after it as it moved towards independence.This unique story is a must-read for readers interested in scientific, social and military history during the WWII, historians of geology, radar, as well as scientific biographies.
Download or read book THE POSTMODERN CHALLENGE TO THE THEORY AND PRACTICE OF EDUCATIONAL ADMINISTRATION written by 2003-01-01 and published by Charles C Thomas Publisher. This book was released on 2003-01-01 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on nearly a decade of scholarship, this is a highly focused book on the implications of postmodernism for the construction and assessment of theory and practice in educational administration. Current ideas of practice are deconstructed, from the notions of sound research to the use of national standards in the preparation of educational leaders along with ways of examining and resolving the theory-practice gap. Part One of the book contains chapters dealing with the rise of postmodernism and describes its broad-based dissent from a century of thought in the field, including a penetrating examination of whether the concept of a field itself is viable. Part Two of the book explores the many ramifications of postmodernism to practice, beginning with ideas concerning educational research. These chapters tackle the tough issues of the efficacy of the Interstate Leaders Licensure Standards (ISLLC) and the national exam as examples of job deskilling and deprofessionalization in the guise of raising standards of preparation of future educational leaders. Other chapters deal with deconstructing the popular managerial ideas contained in Stephen Covey's works and dispute Joe Murphy's call for a new center of gravity in the field as reinforcing the status quo. Finally, the book tackles the issue of the theory-practice gap and indicates that new and progressive theories which anticipate problems of practice are what is required to deal with this persistent issue. The book contains many helpful exhibits in understanding the issues concerning theory and practice, as well as a glossary of terms most commonly found in postmodern discourse. This book is designed for college and university programs engaged in the preparation of educational leaders for ele-mentary/secondary schools and college administrative positions.

This book was released on 2001-03-09 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is generally felt in the cosmology and particle astrophysics community that we have just entered an era which later can only be looked back upon as a golden age. Thanks to the rapid technical development, with powerful new telescopes and other detectors taken into operation at an impressive rate, and the accompanying advancement of theoretical ideas, the picture of the past, present and future Universe is getting ever clearer. Some of the most exciting new findings and expected future developments are discussed in this invaluable volume.The topics covered include the physics of the early Universe and ultra-high energy processes. Emphasis is also put on neutrino physics and astrophysics, with the evidence for non-zero neutrino masses emerging from both solar neutrinos and atmospheric neutrinos covered in great depth. Another field with interesting new results concerns the basic cosmological parameters, where both traditional methods and the potential of new ones, like deep supernova surveys and acoustic peak detections in the cosmic microwave background, are thoroughly discussed. Various aspects of the dark matter problem, such as gravitational lensing estimates of galaxy masses, cluster evolution and hot cluster electron distortions of the thermal microwave background spectrum, are also discussed, as are particle physics candidates of dark matter and methods to detect them. Cosmic rays of matter and antimatter are included as a topic, and so is the problem of the enigmatic dark energy of the vacuum.

Download or read book The Secret Life of Bletchley Park written by Sinclair McKay and published by Aurum. This book was released on 2011-08-26 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bletchley Park was where one of the war’s most famous – and crucial – achievements was made: the cracking of Germany’s “Enigma” code in which its most important military communications were couched. This country house in the Buckinghamshire countryside was home to Britain’s most brilliant mathematical brains, like Alan Turing, and the scene of immense advances in technology – indeed, the birth of modern computing. The military codes deciphered there were instrumental in turning both the Battle of the Atlantic and the war in North Africa. But, though plenty has been written about the boffins, and the codebreaking, fictional and non-fiction – from Robert Harris and Ian McEwan to Andrew Hodges’ biography of Turing – what of the thousands of men and women who lived and worked there during the war? What was life like for them – an odd, secret territory between the civilian and the military? Sinclair McKay’s book is the first history for the general reader of life at Bletchley Park, and an amazing compendium of memories from people now in their eighties – of skating on the frozen lake in the grounds (a depressed Angus Wilson, the novelist, once threw himself in) – of a youthful Roy Jenkins, useless at codebreaking, of the high jinks at nearby accommodation hostels – and of the implacable secrecy that meant girlfriend and boyfriend working in adjacent huts knew nothing about each other’s work.
