The concept of EO

Einstein Online is dedicated to Einstein’s theory of relativity and its applications, which are presented in a way that is understandable to a broad audience. Our authors come from renowned institutions and research institutes all over the world. All articles are available in both German and English, citable and accompanied by numerous illustrations and animations.

While Elementary Einstein introduces readers to the subject matter step by step, our spotlight topics examine individual aspects in greater detail and can be read independently of one another. Related topics and further articles are linked in the sidebar. For technical terms, readers are invited to consult our glossary with about 500 entries.

Einstein Online is a website of the Max Planck Institute for Gravitational Physics (Albert Einstein Institute) and was created in 2005 as a contribution to the World Year of Physics (Einstein Year) on the initiative of AEI scientist Markus Pössel (now head of the Haus der Astronomie – Center for Astronomy Education and Outreach in Heidelberg).
