Cet essai retrace comment l’Astronomie primitive s’est d�velopp�e, s’ouvrant peu � peu � la g�om�trie, � la philosophie et aux m�thodes qui m�neront � Kepler et Newton. En suivant les premi�res observations du Soleil, de la Lune et des �toiles, il montre comment les id�es ont m�ri sur la division du temps, les mouvements des corps c�lestes et les lois qui les r�gissent. Le texte met en lumi�re les grandes �tapes, les outils et les notions qui ont permis de passer d’un ciel observable � une science fond�e sur des mesures et des calculs.

� travers l’expos� des mouvements et des cycles, vous verrez comment les premiers peuples ont appr�hend� la dur�e de l’ann�e, les phases lunaires et les r�volutions des astres. On d�couvre aussi les notions de stabilit� des �toiles, la notion de sph�re et l’�volution des m�thodes qui ont conduit � une compr�hension plus pr�cise du monde c�leste. Le livre aborde des th�mes cl�s comme la pr�cession des �quinoxes, l’aberration de la lumi�re et la nutation, autant de jalons qui ont prouv� que la Terre bouge dans l’espace et que le ciel change avec le temps.

Comment les premiers astronomes ont utilis� les cycles du Soleil et de la Lune pour mesurer le temps et pr�parer les calendriers.
Les notions de mouvement propre, r�volutions sid�rales et synodiques, et la distinction entre positions locales et fixes du ciel.
Des id�es sur la fixit� relative des �toiles, les premiers outils et les m�thodes pour tester les th�ories.
Des avanc�es sur la structure de la Terre, les mouvements d’axe, et les ph�nom�nes comme la pr�cession, l’aberration et la nutation.

Id�al pour les passionn�s d’histoire des sciences et d’astronomie pratique, ainsi que pour ceux qui veulent comprendre les fondements historiques des id�es qui sous-tendent l’observation du ciel.

Store Description

**Please note our transit times are from the date of dispatch.** We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first purchase with us, or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book.
