In questo saggio si esamina la teoria e l’osservazione della corrente equatoriale, la sua direzione e gli effetti sulle rotte oceaniche. Il testo mette a confronto le idee di Colombo con i ragionamenti di filosofi e scienziati del suo tempo, offrendo una lettura chiara delle fonti storiche e delle interpretazioni moderne.

Il volume esplora come l’immaginazione, la navigazione e la scienza si intreccino nel racconto delle grandi esplorazioni. Viene spiegato perch� l’Ammiraglio fu guidato dall’osservazione delle maree, della direzione delle correnti e delle terre emerse lungo il percorso verso le Indie, e come queste intuizioni abbiano influenzato le sue rotte e le successive scoperte.

Come Colombo riconobbe l’esistenza della corrente equatoriale e la sua relazione con le rotte oceaniche.
Il metodo usato per confrontare testi storici, lettere e cronache per capire le indecisioni e le conclusioni dell’epoca.
La discussione su longitudine, mappe antiche e come le mappe portino tracce delle conoscenze del XIV–XV secolo.
Una prospettiva su come idee scientifiche e teorie della Terra influenzarono le scoperte geografiche.

Ideale per lettori interessati alla storia della navigazione, alla geografia storica e alle complesse dinamiche tra mito, matematica e osservazione pratica.

Store Description

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 visit 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. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
