In September 1878, Thomas Alva Edison brashly -- and in advance -- proclaimed his leap forward invention of a viable electrical mild. That statement was once through many months of excessive experimentation that resulted in the winning finishing touch of his Pearl highway station 4 years later. Edison used to be now not on my own -- nor used to be he first -- in constructing an incandescent mild bulb, yet his was once the main profitable of all competing innovations. Drawing from the records within the Edison information, Robert Friedel and Paul Israel clarify how this got here to be. They discover the method of invention in the course of the Menlo Park notes, discussing the complete variety of experiments, together with the checking out of a number of fabrics, the advance of such the most important instruments because the world's top vacuum pump, and the development of the 1st large-scale electric turbines and tool distribution platforms. the result's a desirable tale of pleasure, danger, and competition.

Revised and up to date from the unique 1986 variation, this definitive research of the main well-known invention of America's most famed inventor is totally keyed to the broadcast and digital types of the Edison Papers, inviting the reader to discover extra the striking unique sources.

Inspired via President Dwight D. Eisenhower's "Atoms for Peace" speech, scientists on the Atomic strength fee and the college of California's Radiation Laboratory begun in 1957 a application they known as Plowshare. Joined through like-minded executive officers, scientists, and enterprise leaders, champions of "peaceful nuclear explosions" maintained that they can create new components and isotopes for normal use, construct garage amenities for water or gasoline, mine ores, raise oil and typical fuel creation, generate warmth for strength construction, and build roads, harbors, and canals. by way of harnessing the ability of the atom for nonmilitary reasons, Plowshare backers anticipated to guard American defense, shield U.S. legitimacy and status, and make sure entry to power resources.

Scott Kaufman's large learn in approximately dozen files in 3 countries indicates how technological know-how, politics, and environmentalism converged to form the lasting clash over using nuclear know-how. certainly, regardless of technological and strategic promise, Plowshare's early champions quickly chanced on themselves dealing with a vocal and robust coalition of federal and nation officers, scientists, industrialists, environmentalists, and regular electorate. Skeptical politicians, family and foreign strain to forestall nuclear checking out, and a scarcity of presidency investment critically constrained this system. through the mid-1970s, Plowshare was once, within the phrases of 1 govt legit, "dead as a doornail." in spite of the fact that, the idea of utilizing the atom for peaceable reasons is still alive.

leader engineer Thomas J. Kelly provides a firsthand account of designing, development, checking out, and flying the Apollo lunar module. It was once, he writes, “an aerospace engineer’s dream activity of the century.” Kelly’s account starts off with the creative strategy of sketching ideas to a number of technical demanding situations with an emphasis on safeguard, reliability, and maintainability. He catalogs a number of attempt mess ups, together with propulsion-system leaks, ascent-engine instability, pressure corrosion of the aluminum alloy components, and battery difficulties, in addition to their fixes lower than the ever present constraints of price range and time table. He additionally recaptures the excitement of listening to Apollo 11’s Neil Armstrong record that “The Eagle has landed,” and the satisfaction of getting inadvertently supplied a necessary “lifeboat” for the staff of the disabled Apollo 13.
