Ptolemy championed using astronomical remark and utilized arithmetic in choosing geographical destinations. yet extra importantly, he brought the perform of writing down coordinates of range and longitude for each characteristic drawn on an international map, in order that another person owning simply the textual content of the Geography might reproduce Ptolemy's map at any time, in entire or partly, at any scale.

Here Berggren and Jones render an exemplary translation of the Geography and supply an intensive advent, which treats the historic and technical heritage of Ptolemy's paintings, the contents of the Geography, and the later historical past of the paintings. additionally integrated listed here are distinctive colour reproductions of maps from manuscripts and early published variants of the textual content, consultant of the gorgeous and sensible cartographic artistry that flowed from Ptolemy's paintings. Historians of technological know-how, classicists, and someone who enjoys attractive maps or map making will locate this paintings an crucial addition to their library.

Download E-books A Spectroscopic Atlas of Bright Stars: A Pocket Field Guide (Astronomer's Pocket Field Guide) PDF

By Jack Martin

A Spectroscopic Atlas of the celebs: A Pocket box advisor is a customary reference publication for all novice astronomers attracted to useful spectroscopy or spectrography. For the 1st time in a single position, it identifies greater than 70 (northern hemisphere) shiny stars which are appropriate observational ambitions for either amateurs and astronomy students.

Finder charts are supplied for finding those sometimes-familiar stars. information for every superstar comprises labelled stellar spectra, a spectral profile with spectral traces pointed out. those are with ease laid out on a unmarried web page, contrary tables of spectroscopic houses, and features and wavelengths identified.

This is the 1st Spectral Atlas designed for beginner astronomers. it truly is both suitable to varsity undergraduates, being meant to familiarize astronomers of any age and point of information with labelled stellar spectra and their diverse houses. It comprises a lot information regarding stars that's not easy to discover or inaccessible to so much people.

Download E-books X-Ray Astronomy with the Einstein Satellite: Proceedings of the High Energy Astrophysics Division of the American Astronomical Society Meeting on X-Ray Astronomy held at the Harvard/Smithsonian Center for Astrophysics, Cambridge, Massachusetts, U.S.A., Ja PDF

By G. S. Vaiana (auth.), Riccardo Giacconi (eds.)

Riccardo Giacconi Harvard/Smithsonian heart for Astrophysics The assembly of the excessive power Astrophysics department of the yankee Astronomical Society, held in Cambridge, Massachusetts on January 28- 30, 1980, marks the arriving of age of X-ray astronomy. within the 18 years because the discovery of the 1st extrasolar X-ray resource, Sco X-l, the sphere has skilled an incredibly fast instrumentation improvement culminating with the release on November thirteen, 1978 of the Einstein Ob­ servatory (HEAO-2) which first brought using excessive answer imaging telescopes to the examine of galactic and extragalactic X-ray resources. The Einstein Observatory tools can observe assets as faint as 10-7 Sco X-lor approximately 17 magnitudes fainter. The technological advancements within the box were paralleled by means of a number of recent discoveries: within the early 1960's the detection of nine "X-ray stars", items 10 instances extra luminous in X-rays than the solar and one of the brightest stellar items in any respect wavelengths; within the past due 1960's and early 1970's the invention of the character of such platforms that have been pointed out as collapsed stars (neutron stars and black holes) in mass alternate binary structures, and the detection of the 1st few extragalactic sources.
