How an Eclipse Proved Einstein Right
Original Caption: In Plate 1 is given a half-tone reproduction of one of the negatives taken with th...

On May 29, 1919, a total solar eclipse provided the ideal opportunity to experiment something predicted by Einstein's General Theory of Relativity: a small change in the position of stars around the sun, which is usually impossible to be seen due to the sun's brightness. Two different expeditions were organized: Arthur Eddington and Frank Watson Dyson travelled to the Island of Principe, and Andrew Claude de la Cherois Crommelin and Charles Rundle Davidson travelled to Sobral, Brazil.

The blue belt shows the regions where the eclipse was totally visible; both the island of Principe a...
