Sundials, which decorate church walls, public plazas, and elegant gardens, are first and foremost astronomical instruments. Before understanding how sundials work, one must first understand the apparent motion of the Sun in the sky. In this book, Denis Savoie presents the basics of astronomy required to understand sundials and describes how to design and build your own classical sundial. Written to engage all levels of science readers, the author shows the calculations involved in the sundial's construction and also gives a comprehensive history of time measurement.

Comet nuclei are the most primitive bodies in the solar system. They have been created far away from the early Sun and it is supposed that their material has been altered the least since their formation. The workshop was bringing together representatives of several scientific communities in the fields of interstellar clouds, star-forming regions, the solar nebula, and comets. The intent was to formulate the current understanding and interconnectivity of the various source regions of comet nuclei and their associated compositions and orbital characteristics.

The goal was to better...

The author gives a rigorous, comprehensive coverage of space robotics. His mechatronic approach could be used as a general introduction to mechatronic engineering.

Der Wunsch nach einem Verstandnis von Einsteins Theorien ist unter naturwissenschaftlich Interessierten weit verbreitet - und bleibt doch meist unerfullt. Dieses Buch bietet nun eine einzigartige neue Chance: Mit anschaulichen Gedankenexperimenten, exakten Abbildungen, treffenden Analogien und mit strikt auf Mittelschulmathematik beschrankten Rechenschritten werden Sie behutsam in die immer wieder faszinierende Welt der Relativitatstheorien gefuhrt. Sachlich, grundlich und dennoch faszinierend werden die Zeitdehnung, das Zwillingsparadoxon, Schwarze Locher oder die Rotverschiebung des...

Gli anni della Luna ripercorre la storia dell astronautica durante il periodo piu esaltante della conquista dello spazio, quello compreso tra il lancio dello Sputnik, nel 1957, e l ultima missione lunare portata a termine dall Apollo 17 nel 1972.
Lo spazio, immaginato, raccontato e disegnato da artisti e sognatori durante gli anni Cinquanta, viene finalmente raggiunto con il compagno di viaggio russo nell ottobre del 57. E l inizio di una nuova era, che si guadagna presto le copertine e le prime pagine delle riviste piu famose.

In its revised 2nd edition, this book examines current understanding of the relationship between sunspots and the Earth's climate. Opening with a brief historical review, the text moves on to scrutinize the various current hypotheses. The focus is on how information on the solar cycle and Earth's climate is gathered, and includes discussion of observations, methododology and the physics involved, with the necessary statistics and analysis also provided.

Written by leading exponents in the field, this collection of timely reviews presents observational methods and the latest results of astronomical research as well as their theoretical foundations and interrelations, providing information and scientifically rigorous coverage.

Martian Outpost provides a detailed insight into the various technologies, mission architectures, medical requirements, and training needed to send humans to Mars. It focuses on mission objectives and benefits, and the risks and complexities that are compounded when linked to an overall planet exploration program involving several expeditions and setting up a permanent presence on the surface.

The first section provides the background to sending a human mission to Mars. Analogies are made with early polar exploration and the expeditions of Shackleton, Amundsen, and Mawson. The...
