The Astronomer Jules Janssen
A physicist and an inventor, Jules Janssen (1824-1907) devoted his life to astronomical research. He spent many years traveling around the world to observe total Solar eclipses, demonstrating that a new era of science had just come thanks to the use of both spectroscopy and photography, and persuading the French Government of the necessity of founding a new observatory near Paris. He became its director in 1875. There, at Meudon, he began routine photographic recordings of the Sun surface and had a big refractor and a big reflector built. Meanwhile, he also succeeded in building an Observatory at the summit of Mont-Blanc. The story of this untiring and stubborn globe-trotter is enriched by extracts of the unpublished correspondence with his wife. One can thus understand why Henriette often complained of the solitude in which she was left by her peripatetic husband: “There are men who leave their wives for mistresses; you do it for journeys!” ... Basking in the glow of his success, Janssen was able to undertake the construction of the great astrophysical observatory of which he had dreamed. It was at Meudon that he had it built.

The Emergence of Astrophysics in Asia
This book examines the ways in which attitudes toward astronomy in Australia, China, India, Indonesia, Japan, South Korea, New Zealand, Taiwan, Thailand and Uzbekistan have changed with the times. The emergence of astrophysics was a worldwide phenomenon during the late nineteenth and early twentieth centuries, and it gradually replaced the older-style positional astronomy, which focused on locating and measuring the movements of the planets, stars, etc.. Here you will find national overviews that are at times followed by case studies of individual notable achievements. Although the emphasis is on the developments that occurred around 1900, later pioneering efforts in Australian, Chinese, Indian and Japanese radio astronomy are also included. As the first book ever published on the early development of astrophysics in Asia, the authors fill a chronological and technological void. Though others have already written about earlier astronomical developments in Asia, and about the recent history of astronomy in various Asian nations, no one has examined the emergence of astrophysics, the so-called ‘new astronomy’ in Asia during the late nineteenth and early twentieth centuries.
Silver Screen to Digital
An era has ended. After one hundred and twenty-five years, a change has taken place in cinemas. The thousands of figures formed by silver and coloured pigments can no longer be viewed through transparent film, instead, everything has become digital, compressed, virtual and built into the rapid alternation of millions (hopefully, for quality's sake) of dots, or pixels within a very neat and minuscule grid. But projection is just the last link in a chain that is transforming the most direct language invented by humanity over the centuries. The other links – shooting, editing, special effects, re-elaboration and sound reproduction – have by now undergone radical transformations that have of...
The Great Refractor of Meudon Observatory
The large telescope at Meudon has become legendary. When it was conceived, after 1870, astronomy as a whole was limited to visual observation. Knowledge of the sky was limited to what one could see, assisted only by optical means. The large telescopes produced at this time produced larger images, permitting close-up views: the Meudon telescope was able to accomplish this perfectly. At Meudon, which became the Mecca of visual observation, the major planets were examined in a way that no other telescope had previously been able to. The telescope monitored the state of their atmospheres and mapped the appearance of their surfaces. Through the telescope, one could obtain photographs showing the ...
