Synopsis

On their 100th anniversary, the story of the extraordinary scientific expeditions that ushered in the era of relativity.

In 1919, British scientists led extraordinary expeditions to Brazil and Africa to test Albert Einstein's revolutionary new theory of general relativity in what became the century's most celebrated scientific experiment. The result ushered in a new era and made Einstein a global celebrity by confirming his dramatic prediction that the path of light rays would be bent by gravity. Today, Einstein's theory is scientific fact. Yet the effort to "weigh light" by measuring the gravitational deflection of starlight during the May 29, 1919, solar eclipse has become clouded by myth and skepticism. Could Arthur Eddington and Frank Dyson have gotten the results they claimed? Did the pacifist Eddington falsify evidence to foster peace after a horrific war by validating the theory of a German antiwar campaigner? In No Shadow of a Doubt, Daniel Kennefick provides definitive answers by offering the most comprehensive and authoritative account of how expedition scientists overcame war, bad weather, and equipment problems to make the experiment a triumphant success.

Goodreads review by Jason on May 15, 2020

If you know a little scientific history you know that in 1919 Arthur Eddington found empirical confirmation for Albert Einstein's theory of general relativity by measuring the deflection of light from distant stars by the gravitational force of the sun as measured by the shifting apparent positions......more

Goodreads review by Jacopo on May 20, 2019

I remember hearing a report on NPR about how scientific articles were more likely to be shared and cited if they were written in a story-like fashion. The reason: humans are natural storytellers who delight in narratives with compelling characters, struggles, and resolutions. This is why I'm giving......more

Goodreads review by Brian on May 07, 2019

It's something of a truism that science tends to go through stages, where each new stage can be typified as 'It's more complicated than we thought.' This book demonstrates that this assertion is also true of history of science. It examines the 1919 eclipse expeditions and their conclusions used to b......more

Goodreads review by Vance on June 09, 2019

I thought a really good read. Cogently written, anyone with a moderate understanding of the scientific process will find a lot in this book: theory vs. experiment, nature of science, history. Really good nature of science here.......more

Goodreads review by Alan on May 11, 2024

First two-thirds of the book were very fascinating and compelling discussion of the various characters involved in the science of gravity during ther early 20th century, and the work that went into mounting eclipse expeditions to potentially prove or refute the competing theories. I did feel like th......more
