Nicolaus Copernicus' inquiring mind probes the secrets of the universe during a time when such behavior is considered heretical.
Presents an introduction to the Solar System and the physical features of the eight planets that revolve around the Sun, in a text that includes learning activities.
"Sing along to the tune of "Where is Thumbkin?." Learn about the eight planets in our solar system."
"Get to explore the solar system one planet at a time, counting down from Mercury to Nepture!"--P. [4] of cover.
Looks at the orbital patterns of the planets and the mathematical patterns surrounding them.
The Ballet of the Planets unravels the beautiful mystery of planetary motion, revealing how our understanding of astronomy evolved from Archimedes and Ptolemy to Copernicus, Kepler, and Newton. Mathematician Donald Benson shows that ancient theories of planetary motion were based on the assumptions that the Earth was the center of the universe and the planets moved in a uniform circular motion. Since ancient astronomers noted that occasionally a planet would exhibit retrograde motion--would seem to reverse its direction and move briefly westward--they concluded that the planets moved in epicyclic curves, circles with smaller interior loops, similar to the patterns of a child's Spirograph. With the coming of the Copernican revolution, the retrograde motion was seen to be apparent rather than real, leading to the idea that the planets moved in ellipses. This laid the ground for Newton's great achievement--integrating the concepts of astronomy and mechanics--which revealed not only how the planets moved, but also why. Throughout, Benson focuses on naked-eye astronomy, which makes it easy for the novice to grasp the work of these pioneers of astronomy.
An exciting introduction to the solar system from Chris Ferrie, #1 science book writer for children, and creator of the Baby University series 8 little planets with the Sun at the center.each one wishing it were a little bit better...Old slow Neptune felt it was behind.165 years to circle the sun is an awful long time!the 8th little planet did not worry.It spins on its axis in a really big hurryTo the tune of "Ten Little Monkeys Jumping on the Bed" comes a new bedtime story from bestselling author Chris Ferrie that's sure to get little ones excited about the solar system while learning new facts about each planet!
Is the solar system ordered? Or is it simply the result of random and chaotic accidents? This book takes the reader on a compelling and powerful journey of discovery, revealing the celestial spheres in their astonishingly complex patterns. Movements of the planets are found to correspond accurately with simple geometric figures and musical intervals, pointing to an exciting new perspective on the ancient idea of the "harmony of the spheres." Hartmut Warm's detailed presentation incorporates the distances, velocities, and periods of conjunction of the planets, as well as the rotations of the Sun, Moon, and Venus. Numerous graphics--including color plates--illustrate the extraordinary beauty of geometrical forms that result when the movements of several planets are viewed in relation to one another. Moreover, the author describes and analyzes concepts of the "music of the spheres," with special emphasis on Kepler's revolutionary ideas. The book also discusses current scientific beliefs about the origin of the universe and the solar system, enabling the reader to understand fully how this remarkable research supplements contemporary materialistic views of the cosmos. The appendix includes his mathematical and astronomical methods of calculation, as well as a detailed discussion of their accuracy and validity based on modern astronomical algorithms.
Though the concept of "the universe" suggests the containment of everything, the latest ideas in cosmology hint that our universe may be just one of a multitude of others-a single slice of an infinity of parallel realities. In The Copernicus Complex, the renowned astrophysicist and author Caleb Scharf takes us on a cosmic adventure like no other, from tiny microbes within the Earth to distant exoplanets and beyond, asserting that the age-old Copernican principle is in need of updating. As Scharf argues, when Copernicus proposed that the Earth was not the fixed point at the center of the known universe (and therefore we are not unique), he set in motion a colossal scientific juggernaut, forever changing our vision of nature. But the principle has never been entirely true-we do live at a particular time, in a particular location, under particular circumstances. To solve this conundrum we must put aside our Copernican worldview and embrace the possibility that we are in a delicate balance between mediocrity and significance, order and chaos. Weaving together cutting-edge science and classic storytelling, historical accounts and speculations on what the future holds, The Copernicus Complex presents a compelling argument for what our true cosmic status is, and proposes a way forward for the ultimate quest: to determine life's abundance not just across this universe but across all realities.
