Shifting the Earth


Book Description

Discover how mathematics and science have propelled history From Ancient Greece to the Enlightenment and then on to modern times, Shifting the Earth: The Mathematical Quest to Understand the Motion of the Universe takes readers on a journey motivated by the desire to understand the universe and the motion of the heavens. The author presents a thought-provoking depiction of the sociopolitical environment in which some of the most prominent scientists in history lived and then provides a mathematical account of their contributions. From Eudoxus to Einstein, this fascinating book describes how, beginning in ancient times, pioneers in the sciences and mathematics have dramatically changed our vision of who we are as well as our place in the universe. Readers will discover how Ptolemy's geocentric model evolved into Kepler's heliocentric model, with Copernicus as the critical intermediary. The author explains how one scientific breakthrough set the stage for the next one, and he also places the scientists and their discoveries within the context of history, including: Archimedes, Apollonius, and the Punic Wars Ptolemy and the rise of Christianity Copernicus and the Renaissance Kepler and the Counter-Reformation Newton and the Enlightenment Einstein and the detonation of the atom bomb Each chapter presents the work of a single scientist or mathematician, building on the previous chapters to demonstrate the evolutionary process of discovery. Chapters begin with a narrative section and conclude with a mathematical presentation of one of the scientist's original works. Most of these mathematical presentations, including the section on Einstein's special relativity, are accessible using only basic mathematics; however, readers can skip the mathematical sections and still follow the evolution of science and mathematics. Shifting the Earth is an excellent book for anyone interested in the history of mathematics and how the quest to understand the motion of the heavens has influenced the broader history of humankind.

Book Description

Wayne Luckmann looks back on growing up in Milwaukees South Side during the 1930s and 1940s, sharing hard-fought lessons from his childhood and beyond in this touching memoir. In A Stirring of the Air, a Shifting of the Light, Luckmann celebrates his family, childhood friends, and many others who have played meaningful roles in his life. His recollections include Margaret and Her Children in which he shares the rich heritage of his mothers European family who immigrated to America at the start of the last century. Their deep, abiding loveoften unexpressedhelp turn him into the man he ultimately becomes. In My Fathers Keeper, he explores his fathers side of the family, showing how various relatives influenced his relationship with his dad. This side of the family helps shape his attitudes, perceptions, and relationships with others, especially his son. These recollections seek to preserve moments and memories of things past that were rich in flesh and blood and bone. Although they are now only flickering neural images, they made Luckmann who he is, and they have profound meaning for anyone seeking a bridge to the past and an understanding of self.
