Bridges: The science and art of the world’s most inspiring structures

FREEDownload : Bridges: The science and art of the world’s most inspiring structures

Bridges: The science and art of the world's most inspiring structures by David Blockley
English | 2010 | ISBN: 0199543593 | 329 Pages | PDF | 2 MB
The Brooklyn Bridge, London's Tower Bridge, Sydney's Harbour Bridge, San Francisco's Golden Gate–bridges can be breathtakingly monumental structures, magnificent works of art, and vital arteries that make life vastly easier.

Bridges: The science and art of the world’s most inspiring structures
In Bridges , eminent structural engineer David Blockley takes readers on a fascinating guided tour of bridge construction, ranging from the primitive rope bridges (now mainly found in adventure movies), to Roman aqueducts and the timber trestle railway bridges of the American West, to today's modern marvels, such as the Akashi-Kaikyo Bridge, which has the largest span in the world. Blockley outlines the forces at work on a bridge–tension, compression, and shear–and the basic structural elements that combat these forces–beams, arches, trusses, and suspensions (or BATS). As he does so, he explores some of the great bridges around the world, including such lesser-known masterpieces as the Forth Railway Bridge (featured in Alfred Hitchcock's The Thirty-Nine Steps ), and describes some spectacular failures, such as the recent bridge collapse in Minnesota or the famous failure of the Tacoma Narrows Bridge in 1940. For instance, Blockley discusses the London's Millennium Bridge–the blade of light across the Thames–which displayed an alarming wobble when opened. He explains that when people walk, they not only exert force directly forward, but also exert a lesser force to the side, and the Millennium Bridge engineers did not consider this tiny lateral movement in their otherwise meticulous design. Amazingly enough, this minor omission caused a wobble severe enough to close the bridge for two years. Bridge building is a magnificent example of the practical use of science. But as Blockley shows in this illuminating book, engineers must go beyond science, blending technical experience and creativity to build the spans that connect us all.

Darkness Over Tibet (Mystic Travellers Series)

Darkness Over Tibet (Mystic Travellers Series) by Theodore Illion
English | Aug 1, 1991 | ISBN: 0932813143 | 210 Pages | PDF | 7 MB
IN my book In Secret Tibet I have given an outline of my recent journey to Tibet, showing how, passing through successive contacts with the Tibetan multitude and gangs of brigands, I finally succeeded in visiting Tibetan monasteries in the disguise of a native. After witnessing various marvels, such as the flying lamas and the Tibetan respas* I reached the final stage of the journey in the most inaccessible part of the country where live the genuine Tibetan hermits, who can read people's thoughts and possess the strange power to maintain themselves young almost indefinitely.

Freak Show: Presenting Human Oddities for Amusement and Profit

Freak Show: Presenting Human Oddities for Amusement and Profit By Robert Bogdan
1990 | 336 Pages | ISBN: 0226063127 | EPUB + MOBI | 9 MB + 4 MB

Freak Show: Presenting Human Oddities for Amusement and Profit
From 1840 until 1940, freak shows by the hundreds crisscrossed the United States, from the smallest towns to the largest cities, exhibiting their casts of dwarfs, giants, Siamese twins, bearded ladies, savages, snake charmers, fire eaters, and other oddities. By today's standards such displays would be considered cruel and exploitative the pornography of disability. Yet for one hundred years the freak show was widely accepted as one of America's most popular forms of entertainment.

Robert Bogdan's fascinating social history brings to life the world of the freak show and explores the culture that nurtured and, later, abandoned it. In uncovering this neglected chapter of show business, he describes in detail the flimflam artistry behind the shows, the promoters and the audiences, and the gradual evolution of public opinion from awe to embarrassment. Freaks were not born, Bogdan reveals; they were manufactured by the amusement world, usually with the active participation of the freaks themselves. Many of the "human curiosities" found fame and fortune, becoming the celebrities of their time, until the ascent of professional medicine transformed them from marvels into pathological specimans.

Radioactivity: A History of a Mysterious Science

Radioactivity: A History of a Mysterious Science by Marjorie C. Malley
English | ISBN: 019976641X | August 25, 2011 | PDF | 280 pages | 3 MB
This is the story of a new science. Beginning with an obscure discovery in 1896, radioactivity led researchers on a quest for understanding that ultimately confronted the intersection of knowledge and mystery.

Mysterious from the start, radioactivity attracted researchers who struggled to understand it. What caused certain atoms to give off invisible, penetrating rays? Where did the energy come from? These questions became increasingly pressing when researchers realized the process seemed to continue indefinitely, producing huge quantities of energy. Investigators found cases where radioactivity did change, forcing them to the startling conclusion that radioactive bodies were transmuting into other substances. Chemical elements were not immutable after all. Radioactivity produced traces of matter so minuscule and evanescent that researchers had to devise new techniques and instruments to investigate them.

Scientists in many countries, but especially in laboratories in Paris, Manchester, and Vienna unraveled the details of radioactive transformations. They created a new science with specialized techniques, instruments, journals, and international conferences. Women entered the field in unprecedented numbers. Experiments led to revolutionary ideas about the atom and speculations about atomic energy. The excitement spilled over to the public, who expected marvels and miracles from radium, a scarce element discovered solely by its radioactivity. The new phenomenon enkindled the imagination and awakened ancient themes of literature and myth.

Entrepreneurs created new industries, and physicians devised novel treatments for cancer. Radioactivity gave archaeologists methods for dating artifacts and meteorologists a new explanation for the air's conductivity. Their explorations revealed a mysterious radiation from space. Radioactivity profoundly changed science, politics, and culture. The field produced numerous Nobel Prize winners, yet radioactivity's talented researchers could not solve the mysteries underlying the new phenomenon. That was left to a new generation and a new way of thinking about reality.

Radioactivity presents this fascinating history in a way that is both accessible and appealing to the general reader. Not merely a historical account, the book examines philosophical issues connected with radioactivity, and relates its topics to broader issues regarding the nature of science.
