Available in PDF, EPUB and Kindle. Book excerpt: Today Edmond Halley is known as the scientist whose comet returns every 75 years or so. But he was a man of many talents who did much more than make a prediction about a comet that happen to appear during his time. Probably Halleys biggest impact on history was from an idea for finding the distance to the sun. After viewing a transit of Mercury across the suns face during a starmapping trip to the southern hemisphere, Halley hit on the idea of timing a transit of Venus in different parts of the world as a way of discovering the distance to the sun. Halleys scheme would eventually send Captain James Cook on his first voyage into the South Pacific aboard Endeavour years after Halleys death. Halley himself made several scientific trips to southern waters. His aim was to investigate the earths magnetic field, but he was also charged with attempting to discover new lands in the South Atlantic. Beyond a scrap of land many miles off the coast of Brazil, he found nothing new in the way of land. But measurements of the earths magnetism gave support for his ingenious theory of how the earth is put together. Adventurer Halley also gained fame as an early underwater explorer. He developed a diving bell and a diving helmet and used them under the waters of the English Channel, intending eventually to hunt for sunken treasure. Halley was surely the 17th centurys most active promoter of science, serving for years as editor for publications of the influential Royal Society. He is acclaimed for encouraging the reluctant Isaac Newton to publish his ideas about motion and gravity. Altogether, Halley gave the world much more than a name for a speedy comet.

Download or read book Edmond Halley written by Alan H. Cook and published by Oxford University Press. This book was released on 1998 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: Edmond Halley (1656-1742), MA, LLD, FRS, Capt. RN, Savillian Professor of Geometry and Astronomer Royal, stands pre-eminent among Oxford, English, and European scientists. A contemporary of Wren, Pepys, Hooke, Handel, Purcell, and Dryden, he was a schoolboy in London while the Great Fireraged, and was an active participant in the Enlightenment, an age of profound developments in all the arts and sciences. As a younger contemporary of Isaac Newton, he had a crucial part in the Newtonian revolution in the natural sciences. It was Halley who set the question that led Newton to writethe Principia, and who edited, paid for, and reviewed it. In later years he applied the methods of the Principia widely in astronomy and geophysics. Now more widely known for his prediction of the return of "his" comet, Halley discovered the proper motion of stars, made important studies of themoon's motion, and his investigations of the Earth's magnetic field and of tides were unrialled for centuries. His prediction of the transit of Venus led to Cook's voyage to Tahiti. He was far more than an cloistered academic; his exploits as a naval captain led to perilous adventures, and he wasalso a notable servant of the State. Much material about his eventful career has come to light in recent years, making this a timely new account of the life, scientific interests, and continuing influence of this engaging and adventurous scholar. Sir Alan Cook has written a fascinating andilluminating account of Halley's life and science, making this a unique and highly readable biography of one of the key figures of his time.

Download or read book Exploration of Halley s Comet written by Michael Grewing and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1005 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1985/86 apparition of Halley's Comet turned out to be the most important apparition of a comet ever. It provided a worldwide science community with a wealth of exciting new discoveries, the most remarkable of which was undoubtedly the first image of a cometary nucleus. Halley's Comet is the brightest periodic comet, and the most famous of the 750 known comets. With its 76-year period, its recent appearance was truly a "once-in-a-lifetime" observational opportunity. The 1985/86 apparition was the thirtieth consecutive recorded apparition. Five apparitions ago, the English astronomer Edmond Halley discovered the periodicity of "his" comet and correctly predicted its return in 1758, a triumph for science best appreciated in the context of contemporary views, or rather fears, about comets at that time. The increasingly rapid progress in technological development is very much apparent when one compares the dominant tools for cometary research during Halley's next three apparitions: in 1835 studies were made based on drawings ofthe comet; in 1910 photographic plates were used; while in March 1986 an armada of six spacecraft from four space agencies approached the comet and carried out in situ measurements, 1 AU from the Earth. In 1910, nobody could have dreamed that this was possible, and today it is equally difficult to anticipate what scientists will be able to achieve in 2061.
Download or read book Edmond Halley written by David K. Love and published by Rowman & Littlefield. This book was released on 2023-11-15 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: Edmond Halley is known far and wide thanks largely to the comet bearing his name, the return of which he predicted in 1705. While that discovery would be enough to make the career of any scientist, Halley’s massive contributions to the fields of astronomy, navigation, geophysics, mathematics, engineering, and actuarial science as a young man and eventually as Astronomer Royal are mostly overlooked. Edmond Halley: The Many Discoveries of the Most Curious Astronomer Royal is a revelatory and deeply researched biography of a man whose defining achievement isn’t even the half of it. A jack-of-all-trades when it came to scientific reasoning, an all-around academic and workaholic who couldn’t leave well enough alone, Halley was amazingly productive and prolific. He was behind some of the most groundbreaking discoveries in human history: It was Halley who was the first to accurately plot the stars of the southern hemisphere. He published Isaac Newton’s Principia, arguably the most important scientific text ever written; translated the works of ancient Greek mathematician Apollonius; captained the ship Paramore on a scientific expedition to plot the Earth’s magnetic fields; was the first to calculate mortality annuities, creating the foundation for actuarial science; made improvements to the diving bell; surveyed the tides of the English Channel; and began the movement to accurately measure the distance between the Earth and Sun, unlocking the key to determining the distances to the nearest stars. In this incisive and perceptive biography, author David K. Love reveals the boundless mind and endless curiosity of Edmond Halley firmly cementing the legacy of the second Astronomer Royal among the first-rate scientists of his time.

Download or read book Halley s Quest written by Julie Wakefield and published by National Academies Press. This book was released on 2005-09-20 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: For most people, Edmond Halley is best known for accurately predicting the periodic appearance of the comet that ultimately would bear his name. But his greatest achievement may have been overlookedâ€" indeed few people know that it was Halley who solved the riddle of accurate navigation for all sea-going vessels. As seventeenth-century scientists gradually came to believe that the inside of the Earth was magnetized they were puzzled by the fact magnetic north not only varied slightly from place to place, but gradually changed over time, suggesting a slow variation of the Earth's magnetic field. But if the Earth was permanently magnetized, how could its magnetism vary? Edmond Halley, Britain's Astronomer Royal, ingeniously proposed that the Earth contained a number of spherical shells, one inside the other, each magnetized differently, each slowly rotating in relation to the others. This brilliant deduction earned Halley the command of a small sailing ship, the 52-foot Paramore, and with it, a royal mandate. Halley was to sail forth "to stand so far into the South, till you discover the Coast of the Terra Incognita." But more importantly, determine the variation between true and magnetic north in order to more accurately calculate longitudeâ€"a feat that would improve Britain's navigational skills and ensure its dominance of the high seas. Halley's Quest takes readers on a trilogy of sea voyages, each of which proved to be as novel and revealing as it was difficult and controversial. But more than a yarn of risk and adventure, the story at the core of the book is a deeply personal and intellectual tale that captures the science and the spirit of an almost forgotten episode in the history of navigation. Once branded a heretic by the Church and denied a prestigious scholarly chair at Oxford University, Halley ultimately changed the course of science, producing charts that described more accurate ways to navigate and documenting new geophysical phenomena ranging from ocean patterns to the motion of Jupiter's moons. This delightful book emphasizes the drama of Halley's mission and the passion of an era hungry for the stories science had to tell.

Download or read book How James Watt Invented the Copier written by René Schils and published by Springer Science & Business Media. This book was released on 2011-12-15 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Features 25 different scientists and the ideas which may not have made them famous, but made history... Typically, we remember our greatest scientists from one single invention, one new formula or one incredible breakthrough. This narrow perspective does not give justice to the versatility of many scientists who also earned a reputation in other areas of science. James Watt, for instance, is known for inventing the steam engine, yet most people do not know that he also invented the copier. Alexander Graham Bell of course invented the telephone, but only few know that he invented artificial breathing equipment, a prototype of the ‘iron lung’. Edmond Halley, whose name is associated with the comet that visits Earth every 75 years, produced the first mortality tables, used for life insurances. This entertaining book is aimed at anyone who enjoys reading about inventions and discoveries by the most creative minds. Detailed illustrations of the forgotten designs and ideas enrich the work throughout.
