In 1915, British astronomer Arthur Stanley Eddington was fascinated with Einstein’s new theory of general relativity. The theory talks about how forces push and pull objects in space. Einstein said that the sun’s gravity could pull and bend light.
To test this, astronomers decided to photograph a solar eclipse. The eclipse would allow them to photograph the stars before and during the solar eclipse. If the star’s position moved, then it was evidence that that light had bent. Eddington and his team traveled from England to the island of Principe, just off the African coast, to photograph the eclipse.
In simple language, this nonfiction illustrated picture book explains how the push (acceleration) and pull (gravity) of space affects light. Back matter includes information on Einstein, Eddington, and the original photograph of the 1919 solar eclipse.
'The text of the book is wonderfully clear and easy to follow, and the illustrations are great, both lively and informative. The story of the eclipse unfolds dramatically, and the science is explained vividly and correctly.' Daniel John Kennefick, Astrophysicist and Science Historian
The story of America and African Americans is a story of hope and inspiration and unwavering courage. But it is also the story of injustice; of a country divided by law, education, and wealth; of a people whose struggles and achievements helped define their country.
Kadir Nelson, one of this generation's most accomplished, award-winning artists, has created an epic yet intimate introduction to the history of America and African Americans, from colonial days through the civil rights movement. Written in the voice of an "Everywoman," an unnamed narrator whose forebears came to this country on slave ships and who lived to cast her vote for the first African American president, Heart and Soul touches on some of the great transformative events and small victories of that history. This inspiring book demonstrates that in gaining their freedom and equal rights, African Americans helped our country achieve its promise of liberty and justice-the true heart and soul of our nation.
