On April 8, 2024, millions of Americans will experience an awe-inspiring phenomenon: a total eclipse of the sun. In Sun Moon Earth, astronomer Tyler Nordgren illustrates how this most seemingly unnatural of natural phenomena was transformed from a fearsome omen to a tourist attraction. From the astrologers of ancient China and Babylon to the high priests of the Maya, Sun Moon Earth takes us around the world to show how different cultures interpreted these dramatic events. Greek philosophers discovered eclipses' cause and used them to measure their world and the cosmos beyond. Victorian-era scientists mounted eclipse expeditions during the age of globe-spanning empires. And modern-day physicists continue to use eclipses to confirm Einstein's theory of relativity. Beautifully illustrated and lyrically written, Sun Moon Earth is the ideal guide for all eclipse watchers and star gazers alike.

Presents a story about how eclipses of the Sun and Moon occur.

A thrilling adventure story chronicling the perilous journey of the scientists who set out to prove the theory of relativity--the results of which catapulted Albert Einstein to fame and forever changed our understanding of the universe. In 1911, a relatively unknown physicist named Albert Einstein published his preliminary theory of gravity. But it hadn't been tested. To do that, he needed a photograph of starlight as it passed the sun during a total solar eclipse. So began a nearly decade-long quest by seven determined astronomers from observatories in four countries, who traveled the world during five eclipses to capture the elusive sight. Over the years, they faced thunderstorms, the ravages of a world war, lost equipment, and local superstitions. Finally, in May of 1919, British expeditions to northern Brazil and the island of Príncipe managed to photograph the stars, confirming Einstein's theory. At its heart, this is a story of frustration, faith, and ultimate victory--and of the scientists whose efforts helped build the framework for the big bang theory, catapulted Einstein to international fame, and shook the foundation of physics.
