Who is Galileo Galilei?

Galileo Galilei was born on 15 February 1564, in Pisa, Italy. He was a mathematician, astronomer, physicist, writer, and philosopher. He had a great contribution in the scientific revolution. His greatest achievement was undoubtedly his virtual invention of the telescope. Hearing early in 1609 that a Dutch optician, named Lippershey, had produced an instrument by which the apparent size of remote objects was magnified, Galileo at once realized the principle by which such a result could alone be attained, and, after a single night devoted to consideration of the laws of refraction, he succeeded in constructing a telescope which magnified three times, its magnifying power being soon increased to thirty-two. n June 1633, Galileo was condemned to life imprisonment for heresy. His writings about these subjects were banned, and printers were forbidden to publish anything further by him or even to reprint his previous works. Outside Italy, however, his writings were translated into Latin and were read by scholars throughout Europe. Galileo remained under imprisonment until his death in 1642.
