From this he made the correct deduction that these dark areas were shadows cast by craters and mountains. This controversy resulted in Galileos Istoria e dimostrazioni intorno alle macchie solari e loro accidenti (History and Demonstrations Concerning Sunspots and Their Properties, or Letters on Sunspots), which appeared in 1613. Galileo died in 1642, the year that Newton was born. Now Galileo could see the shape of Venus as sunlight reflected off its surface. This creation of the modern science of telescopic astronomy was clearly born in 1610 when he published his work called Sidereus Nuncius or the Starry Messenger. In 1588 Galileo applied for the chair of mathematics at the University of Bologna but was unsuccessful. Curious about the Sun, Galileo used his telescope to learn more. he also made observations of sunspots. They were; after all, created by God and therefore flawless.

His portrait of Galileo, drawn to the life, is certainly not a flattering one. How fast do objects fall to the earth? . In the midst of his busy life he continued his research on motion, and by 1609 he had determined that the distance fallen by a body is proportional to the square of the elapsed time (the law of falling bodies) and that the trajectory of a projectile is a parabola, both conclusions that contradicted Aristotelian physics.

Omissions? Scheiner observed sunspots in 1611 and published his results in 1612. He turned the telescope into an important tool of understanding the universe we live in. Galileo then began to prepare himself to teach Aristotelian philosophy and mathematics, and several of his lectures have survived. The Churchs argument was that it directly contradicted scripture and was therefore heretical. He also sold a proportional compass, or sector, of his own devising, made by an artisan whom he employed in his house. It's now broadly understood that Marius was an independent observer of Jupiter's moons. Galileo used observation and experimentation to interrogate and challenge received wisdom and traditional ideas.
