The exhibition E3 – Einstein, Eddington and the Eclipse – focused on historical aspects of the expeditions which brought Eddington and his companions Cottingham, Davidson and Crommelin to the island of Príncipe and  to Sobral, Brazil. It focuses on the unlikely encounter between Einstein and Eddington, the preparations of the expeditions in a time of war, the voyages, the observations and the impact of these expeditions on the national and international community of  astronomers, and also on the general public. It pays particular attention to the role of institutions, astronomers and experts in Lisbon, Portugal.

From 16th of May  and 8th of September of 2019 it will be at the University of Lisbon Museum of  Natural History and Science (MUNHAC).

The opening coincided with the release of the emission of CTT (Portuguese Post) postal stamps alluding to the centenary of the eclipse observations of 19th of May 1919 . See footage of this session in this video.

The comics is scheduled to be released on 6 November 2019, signalling the public presentation of the results of the two British expeditions, at the joint meeting of the Royal Society of London and the Royal Astronomical Society, on the 6 November 1919.


E3 – Multiple Gazes

Multiple Gazes are a form of collaboration of the E3 exhibition in which different visions of the same event might be found.

We challenge institutions with exhibitions focused in E3 related themes to share a slideshow with 8 to 15 images, one image in each slide with a short caption (including English) that transmits the exhibition’s perspective regarding these “characters” – Einstein, Eddington, Eclipse.
