For slaves, life on the plantation was mostly hard work, with little reward. There was little food and bum Homs for slaves. Depending on their size, plantations had a multitude of buildings. These included the homes of the master's family, overseer, and slaves, as well as, outbuildings, barns, and workshops. Large plantations operated like self-sustaining villages, and thus, were often isolated from the outside world.

Galileo Galilei (Pisa, Tuscany, February 15, 1564-Arcetri, Tuscany, January 8, 1642) was an Italian astronomer, philosopher, engineer, mathematician and physicist, closely related to the scientific revolution. Eminent man of the Renaissance, showed interest in almost all sciences and arts (music, literature, painting). His achievements include the improvement of the telescope, a wide variety of astronomical observations, the first law of movement and a decisive support for the «Copernicus Revolution». He has been considered the "father of modern astronomy", the "father of modern physics" and the "father of science".
In May of 1609, Galileo receives from Paris a letter from the Frenchman Jacques Badovere, one of his former students, who confirms an insistent rumor: the existence of a telescope that allows to see distant objects. Built in Holland by the lens manufacturer Hans Lippershey, this telescope would have already allowed to see stars invisible to the naked eye. With this unique description, Galileo, who no longer gives courses to Cosme II de Médicis, builds his first telescope. Unlike the Dutch telescope, it does not deform the objects and increases them 6 times, that is, twice as much as its opponent. It is also the only one of the time that manages to obtain a right image thanks to the use of a diverging lens in the eyepiece. This invention marks a turning point in the life of Galileo.
