This video is part of a series of educational videos that ESA is releasing based on the five visionaries that lent their name to Europe’s space freighters.

Jules Verne, Johannes Kepler, Edoardo Amaldi, Albert Einstein and Georges Lemaître form the inspiration to explain the principles of physics to young and older audiences.

Presented by Anu Ojha, this video offers a good basis to introduce schoolchildren and the general public to concepts of special and general relativities and their implication in space flight.

Accompanying these videos are also a new set of resources that ESA education is producing: Teach with Space, a large set of demonstrations and teacher guides intended to bring the excitement of space into the classroom to inspire the next generation.
