Download or read book World-maps for Finding the Direction and Distance to Mecca written by David King and published by BRILL. This book was released on 2021-09-06 with total page 670 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two remarkable Iranian world-maps were discovered in 1989 and 1995. Both are made of brass and date from 17th-century Iran. Mecca is at the centre and a highly sophisticated longitude and latitude grid enables the user to determine the direction and distance to Mecca for anywhere in the world between Andalusia and China. Prior to the discovery of these maps it was thought that such cartographic grids were conceived in Europe ca. 1910. This richly-illustrated book presents an overview of the ways in which Muslims over the centuries have determined the sacred direction towards Mecca (qibla) and then describes the two world-maps in detail. The author shows that the geographical data derives from a 15th-century Central Asian source and that the mathematics underlying the grid was developed in 9th-century Baghdad.

Available in PDF, EPUB and Kindle. Book excerpt: Misurare il tempo è qualcosa di innato per l’uomo: il nostro stesso organismo funziona secondo cicli scanditi dalla rotazione della Terra intorno al Sole. Ma se un tempo bastavano i calendari a segnalare l’arrivo delle stagioni e a indicare quando iniziare i lavori nei campi, oggi le cose sono cambiate: i nostri ritmi sono scanditi da orologi atomici disseminati nei laboratori di ricerca, nelle aziende e in decine di satelliti artificiali in orbita costante sopra di noi. Da un lato, la loro funzione è sincronizzare tutte le attività in corso sul pianeta, dal trasporto dei passeggeri alle operazioni in borsa, dalla ricerca scientifica alle trasmissioni tv e radio. Dall’altro, la loro enorme precisione è importante per rispondere alle domande ancora aperte della fisica fondamentale o per scrutare l’ignoto dell’universo con i radiotelescopi. Le clessidre degli Egizi avevano uno scarto di qualche minuto ogni ora, gli orologi più precisi di oggi perdono un secondo ogni 4,5 miliardi di anni. Perché l’uomo cerca una precisione sempre più ossessiva nella misurazione del tempo? Come è possibile trovare nell’atomo questa precisione e trasferirla alla scienza o alla vita di tutti i giorni? Dal calendario Maya a quello gregoriano, dal GPS agli orologi ottici, dal raffreddamento laser alla velocità del neutrino, il volume di Davide Calonico e Riccardo Oldani risponde a queste domande, ripercorrendo tutta la storia della metrologia del tempo e descrivendo sia le tecnologie sviluppate dall'uomo nel corso dei secoli in un intenso rapporto con la fisica, sia le ricadute e i miglioramenti costantemente generati sulla nostra vita.

Download or read book Splitting The Second written by Tony Jones and published by CRC Press. This book was released on 2000-01-01 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until the 1950s timekeeping was based on the apparent motion of the Sun that in turn reflected the rotation of the Earth on its axis. But the Earth does not turn smoothly. By the 1940s it was clear that the length of the day fluctuated unpredictably and with it the length of the second. Astronomers wanted to redefine the second in terms of the motions of the Moon and the planets. Physicists wanted to dispense with astronomical time altogether and define the second in terms of the fundamental properties of atoms. The physicists won. The revolution began in June 1955 with the operation of the first successful atomic clock and was complete by October 1967 when the atomic second ousted the astronomical second as the international unit of time. Splitting the Second: The Story of Atomic Time presents the story of this revolution, explaining how atomic clocks work, how more than 200 of them are used to form the world's time, and why we need leap seconds. The book illustrates how accurate time is distributed around the world and what it is used for. It concludes with a look at the future of timekeeping.
