Hello! Here is my assignment from Mr.Livingston: Summarize each of the inventions and inventors you studied this week and how they impacted history. Also, explain the most interesting thing you learned this week, and why.
I learned about the Mariner’s Astrolabe, The Double Entry Bookkeeping, Luca Pacioli, and Leonardo Da Vinci.
The Mariner’s Astrolabe. The mariner’s astrolabe was an navigation tool used for taking the altitude of the sun or stars. Its history dates as far back as the Ancient Period and into Medieval Period. Its name means “to take a star” or “star taker.” The mariner’s astrolabe was the preferred instrument for more than 200 years.
Double Entry Bookkeeping. Double entry bookkeeping system first invented in Italy by a church father who’s named Luca Bartolomes Pacioli. He was the mathematician and contemporary of Leonardo Da Vinci. He wrote a book which name was “Summa de Arithmetica, geometry, proportions et proportionalità”. This book called Accounting bible.
Luca Pacioli. Fra Luca Bartolomeo de Pacioli (sometimes Paccioli or Paciolo; c. 1447 – 19 June 1517) was an Italian mathematician, Franciscan friar, collaborator with Leonardo da Vinci, and an early contributor to the field now known as accounting.
Leonardo Da Vinci this inventor was my favorite out of the four inventions I learned about this week because I like his name and he has a nice goatee. Leonardo da Vinci (1452-1519) was born in Anchiano, Tuscany (now Italy), close to the town of Vinci that provided the surname we associate with him today. In his own time he was known just as Leonardo or as “Il Florentine,” since he lived near Florence and was famed as an artist, inventor and thinker.
And that’s it for this essay!
