The graph is the Galilean former residence that is located in Italian pizza city. (a photography / Che Jixin)When Galileo is 17 years old, cure learns in pizza university, but what he is interested is maths, physics and instrument are made. With maths and physical be good at, famed because of be good at arguing entire school. Galileo left school because of domestic deficient 1585, but his do all one can teachs oneself, the scientific literature with absorption research Greek ancient time, intercurrent palpability determines the hydrostatics balance of alloy composition. Galileo drew up 1586 paper " balance " . This achievement causes the attention of countrywide academia, people call him " contemporary Archimedes " . Removed Galilean emigrant Foluolunsa 1610, among ever went to Rome twice. It is the binoculars that revealed him 1611 first, it is the 2nd to went 1633 religious court be on trial be on trial. Galilean 1633 with " object evil of pope, advocate learning " accusation is sentenced all one's life by Roman inquisition imprisonment. After be being convictioned by religious court, the mechanical research of one's early years makes his main work again. The generation of the Galileo change the size of object speed and direction or acceleration puts in Zhu Li's action 's charge, this is the objective understanding of the property to force, also be Newton the rudiment of the 2nd law. The discovery of inertial principle did away with the old idea that force is athletic reason, and the reason that thinks force is change movement condition. After more than 300 years on November 10, 1979, papal announce on public meeting: 1633 it is inequitable to be being adjudged Galileanly. (Galilean picture comes from at the network)
