Renaissance encouraged the development of science. Especially in science, observation and experimentations were included. Several great Scientists contributed much to the progress of L Science in several fields – Physics, Mathematics, Astronomy, Geography, and Chemistry.
In 1500, Jackot Nufer (Swiss) carried out the first successful caesarean operation. Roger Bacon succeeded in discovering many uses for gun powder and the magnifying lens. Leonardo, da Vinci (Italy) invented the ‘Parachute’ in 1480. He produced the diagram of a ‘Flying machine’, which inspired the invention of the Aeroplane later.
Nicholas Copernicus (Poland) made progress in the study of Astronomy. He propounded the ‘Helio-Centric Theory’ as opposed r to the Ptolemaic ‘Geo-Centric theory’. He affirmed the principle that “The earth is round and it moves round the Sun, which is the centre of our planetary system”.
John Kepler (Germany) improved upon the theory of Copernicus. He proved that “The planets including the Earth revolve around the Sun in Elliptical orbits and not in Circles as indicated by Copernicus”. Hans Lipperhey (Germany) invented the ‘Telescope’ in 1608. Galileo (Italy) r explained the Copernicus theory. He improved the Telescope. He observed mountains on the Moon surface and rings around the Saturn through the Telescope.
He declared that the world is controlled by natural laws. He discovered ‘Thermometer’, ‘Barometer’ and ‘Pendulum’. Sir Isaac Newton (England) proposed the ‘Laws of Gravitation’ govern ing the motions of the Planets around the Sun and the Moon around the Earth. William Harvey (England) elucidated the ‘Blood circulation’.
He explained how blood circulates from the heart through arteries to the various parts of the body and comes back to the heart through veins. John Gutenberg (Germany) set up the first Printing press on a large scale in Germany in 1440.
