Michael Hoskin

Born in Canada; raised in Zambia; serving in Angola. Dr. Steve Foster has lived a remarkable life as a missionary surgeon, bringing what he calls "the benefit of steel" to relieve suffering people in times of war and poverty. Steve is one of many missionaries in his family, a lineage with more than 100 years of worldwide service. This is the story of Steve and his wife Peggy and how God shaped their lives for service in Angola, where they have been since 1978. As the Fosters' story is revealed to you in these pages, you will learn the history of Angola and its civil war and witness stories of miracles, dangers and heartbreak.

This beautifully structured book presents the essentials of William and Caroline Herschel’s pioneering achievements in late 18th-century astronomy. Michael Hoskin shows that William Herschel was the first observational cosmologist and one of the first observers to attack the sidereal universe beyond the solar system:Herschel built instruments far better than any being used at the royal observatory. Aided by his sister Caroline, he commenced a great systematic survey that led to his discovery of Uranus in 1781. Unlike observers before him, whose telescopes did not reveal them as astronomical objects, Herschel did not ignore misty patches of light. Hoskins points out Herschel’s achievement in surveying, cataloguing, and describing them as “nebulae” and even coming to the correct conclusion that their structure evolved over time, with Newton’s gravity being the agent of change. Herschel’s surveys established a new astronomy – looking at the universe rather than the planets! Michael Hoskin’s account includes sketches and diagrams from Herschel’s manuscripts in the Royal Astronomical Society Archives in which he attempts to delineate the structure of the Milky Way galaxy. While it is well-known that Herschel was a revolutionary in telescope design who constructed the world’s largest telescopes, Hoskin also gives the full picture of the man as an entrepreneur who built and traded some 400 telescopes. Hoskin also pays close attention to the role of William's sister Caroline Herschel, who is usually portrayed as a “helpmate” to her brother. But in fact she became a significant astronomer in her own right. This book also offers a wealth of information of the wider Herschel family. It is enriched by a complete set of portraits of William and Caroline Herschel with an extensive set of images of their residences and closes with a charming appendix on how visitors to the Herschels recorded their encounters. William and Caroline Herschel – Pioneers in Late 18th-Century Astronomy will appeal to amateur astronomers and all those interested in popular astronomy. This book will rapidly establish itself as the primary introductory work for students, astronomers, and scholars working on the history of natural science in the late 18th century.

The astronomical observations of William Herschel (1738–1822) made him question the accepted model of the clockwork universe. This volume explains the development of Herschel's thoughts on what he called 'the construction of the heavens' and reprints his principal papers on this subject. The preliminary chapters provide an introduction to Herschel, including his unusual path to astronomy, the discovery of Uranus and his work on the evolution of stellar clusters, which eventually led him to challenge the unchanging Newtonian universe. The second half of the text comprises eight of Herschel's key papers on what we today would call cosmology, representing his progress between 1783 and 1814, fully annotated with historical notes and modern astrophysical explanations. Ideal for undergraduate and postgraduate students in the history of science and in astronomy, this volume explains Herschel's pivotal role in the transformation from the clockwork universe to the 'biological' universe of modern astronomy.

Discoverers of the Universe tells the gripping story of William Herschel, the brilliant, fiercely ambitious, emotionally complex musician and composer who became court astronomer to Britain's King George III, and of William's sister, Caroline, who assisted him in his observations of the night sky and became an accomplished astronomer in her own right. Together, they transformed our view of the universe from the unchanging, mechanical creation of Newton's clockmaker god to the ever-evolving, incredibly dynamic cosmos that it truly is. William was in his forties when his amateur observations using a homemade telescope led to his discovery of Uranus, and an invitation to King George's court. He coined the term "asteroid," discovered infrared radiation, was the first to realize that our solar system is moving through space, discovered 2,500 nebulae that form the basis of the catalog astronomers use today, and was unrivalled as a telescope builder. Caroline shared William's passion for astronomy, recording his observations during night watches and organizing his papers for publication. She was the first salaried woman astronomer in history, a pioneer who herself discovered nine comets and became a role model for women in the sciences. Written by the world's premier expert on the Herschels, Discoverers of the Universe traces William and Caroline's many extraordinary contributions to astronomy, shedding new light on their productive but complicated relationship, and setting their scientific achievements in the context of their personal struggles, larger-than-life ambitions, bitter disappointments, and astonishing triumphs.

This is a short history of astronomy, from pre-historic times to the origins of astrophysics in the mid-19th century. Amongst other things, it traces the development of the heliocentric thesis, from Ptolemy and his influences to Copernicus, via Islam.
