1829507894Knight and Lacey London 1829. Card Covers. Very Good Condition. The Mechanics' Magazine in October 1829 documented one of the most pivotal moments in railway history the Rainhill Trials a competition held to determine the best locomotive for the Liverpool & Manchester Railway. This event showcased several steam engines : The Rocket designed by Robert Stephenson won the competition and established a standard for future steam engines. It introduced a multi-tubular boiler improving efficiency and speed. The Sans Pareil built by Timothy Hackworth this locomotive was a strong contender but was ultimately less efficient than the Rocket and The Novelty designed by John Braithwaite and John Ericsson this locomotive was lightweight and innovative but suffered mechanical failures during the trials. The Rainhill Trials proved that locomotives were feasible for railway transport shaping the future of rail travel and marking the beginning of the age of speed transforming how people lived worked and travelled. Three complete issues of the Mechanics' Magazine No's 323 324 & 325 for October 1829. Genuine Original and Packed with Innovation! This weekly magazine isn't just a fragment of history it's a window into the cutting-edge advancements of the Victorian era! Since 1823 The Mechanics' Magazine has tackled revolutionary topics from printing presses to vapor baths hydrostatics and hydraulics. It dives into breakthrough safety measures preventing explosive contaminated air while exploring the mechanics of oxy-hydrogen blowpipes and self-laying rail carriages. Every page crackles with Victorian-era engineering brilliance capturing the relentless drive for invention that shaped the modern world! This is an exclusive standalone issue carefully separated from its original volume; authentic original and uniquely crafted. It is not a reprint or reproduction but a distinct piece in its own right. Preserved in a modern card cover prepared for practicality - an unassuming but serviceable presentation that favours function over finery. Size: 13 x 21 cms.

Follwing the discovery of X-rays by Röntgen Bexquerel investigated fluorescent materials to see if they also emitted X-rays. He exposed a fluorescent uranium salt pechblende to light and then placed it on a wrapped photographic plate.He found that a faint image was left on the plate which he believed was due to the pichblende emitting the light it had absorbed as a more penetrating radiation. However by chace he left a sample that had not been exposed to light on top of a photographic plate in a drawer. he noticed that the photographic plate also had a a faint image of the pechblende. After several chemical tests he concluded that these "Becquerel rays" were a property of atoms. He had by chace discovered radio-activity and prompted thee beginning of the nuclear age. He shared the Nobel Prize for Physics in 1903 with Marie and Pierre Curie. The "Becquerel Rays" were later discovered to be a composite of three forms of emanation distinguished by Rutherford as alpha beta and gamma rays.Dibner: 163 the later Mémoire from 1903 - PMM: 393 1903- Mémoire - Garrison & Morton: 2001 only the first paper. - Magie "A Sourve Book in Physics" p. 610 ff. - Norman:157. </em> hardcover
