Johannes Kepler (1571-1630) is remembered, along with Copernicus and Galileo, as one of the greatest Renaissance astronomers. A gifted analytical thinker, he made major contributions to physics, astronomy, and mathematics. Kepler was trained as a theologian, yet did not hesitate to challenge church doctrine and prevailing scientific beliefs by supporting the theory of a Sun-centered solar system. As Imperial Mathematician to the Holy Roman Emperor, he analyzed the precise observations of the heavens that his predecessor, the great astronomer Tycho Brahe, had recorded. The book follows the ingenious scientist along the difficult pathway from raw data to his monumental discovery--the three Laws of Planetary Motion. Kepler also made fundamental contributions to optical theory, including a correct description of the function of the eye and a new and improved telescope design. His unique Rudolfine Tables , universal calculations of planetary motion, were unprecedented in their accuracy. James Voelkel vividly describes these scientific achievements, providing enough background in astronomy and geometry so even beginners can follow Kepler's thinking and enjoy this book. Equally captivating is his account of Kepler's tumultuous life, plagued by misery, disease, war, and fervent religious persecution.
Oxford Portraits in Science is an ongoing series of scientific biographies for young adults. Written by top scholars and writers, each biography examines the personality of its subject as well as the thought process leading to his or her discoveries. These illustrated biographies combine accessible technical information with compelling personal stories to portray the scientists whose work has shaped our understanding of the natural world.
Although I did have to trudge my way through this book at parts, I really enjoyed it actually. I thought it was very funny how he picked his second wife and was illuminating to have more insight into the lack of freedom of religion at the time. Kepler was worried about his life and his family's lives always because he was Lutherin. He had to move several times because of this. I felt like it also helped me to appreciate so many people's contributions to the knowledge that we have in society today. It took Kepler most of his adult career to finish the Rudolfine tables and struggled so much with the mathematical equasions to figure out the movements of the planets, and this guy didn't even have a telescope!! He worked for years to share with us what we just take for granted. I was very glad I read it. :)
It took forever for me and my daughter to force ourselves through this read. While potions of it were completely fascinating, other parts made me long for a dull abridged text book version. Honestly I don’t see any high school age student completing it; which is this titles target age group. The layout was not done well and clearer examples of Kepler’s laws and formulas were needed.
