So I drive to the science building of Central Connecticut State University, about two hours southwest of Boston. There, in an office crammed with books, papers and The Lord of the Rings fan merchandise, I meet astronomer Kristine Larsen.

This book is about the archaeology of science, or what can be learnt from the systematic examination of the artefacts made by precision craftsmen for the study of the natural world.

An international authority on historical scientific instruments, Gerard Turner has collected here his essays on European astrolabes and related topics. By the astrolabe had nearly ceased to be made and used in.

Francis M. Rogers, from Harvard University wrote the book "Precision Astrolabe; Portuguese Navigator and Transoceanic Aviation" published in Lisbon by the Academia Internacional da Cultura.

The Story of the Astrolabe, the Original Smartphone getting higher precision in astrological predictions.” the topic of a book he published in Precision astrolabe book astrolabe. The Astrolabe, a new book by James E. Morrison, is an absolutely unique and wonderful book on the mathematics needed to create accurate, beautiful designs of astrolabes, quadrants and other related instruments.

I can’t recommend it enough to those who share the interests of this blog. Geodesy (/dʒiːˈɒdɨsi/), also named geodetics, is the scientific discipline that deals with the measurement and representation of the Earth. The history of geodesy began in pre-scientific antiquity and blossomed during the Age of Enlightenment.

Early ideas about the figure of the Earth held the Earth to be flat (see flat Earth), and the heavens a physical dome spanning over it. adshelp[at] The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative Agreement NNX16AC86A.

An international authority on historical scientific instruments, Gerard Turner has collected here his essays on European astrolabes and related topics. The history of computing hardware covers the developments from early simple devices to aid calculation to modern day the 20th century, most calculations were done by humans.

Early mechanical tools to help humans with digital calculations, like the abacus, were referred to as calculating machines or calculators (and other proprietary names). This is the book “Quadrans vetus”, a technical manual on the construction and use of the ‘old quadrant’, as distinct from the astrolabe-quadrant, or quadrans text was written in Montpellier, c (perhaps in ), and it is variously ascribed to Johannes Anglicus, John of Montpellier or to Robertus Anglicus.

Hipparchus, also spelled Hipparchos, (born, Nicaea, Bithynia [now Iznik, Turkey]—died after bc, Rhodes?), Greek astronomer and mathematician who made fundamental contributions to the advancement of astronomy as a mathematical science and to the foundations of gh he is commonly ranked among the greatest scientists of antiquity, very little is known about his life.

This unique ephemeris is one of the most complete and convenient references available for astrological calculation.

During a fascinating luncheon, in fact, the crew demonstrated their compass and astrolabe, drawing tools and almanac tables, a high-precision clock, plus newer methods they used to fix our latitude and longitude on maps based on the sun and stars.

They were sailing by heavenly rather than earthly lights. "The Astrolabe: An instrument with a past and a future," by James E. Morrison (published by Janus), offers information about the history and development of the astrolabe and related instruments. "Build a Simple Sextant," a teacher's resource provided by NASA, offers an alternate way to make a similar homemade instrument.

The astrolabe is an instrument of some antiquity; Persian models dating as far back as the eleventh century have been found, and Chaucer wrote a Treatise on it in the late s.

By the Elizabethan era it consisted of a large brass ring fitted with an alidade or sighting rule. The user held the astrolabe by a loop at the top, turned the alidade. Simple Compass - No unnecessary permissions needed. - a tiny astrolabe in your smartphone - Understand how an astrolabe works.
