The Theory of Relativity – Simply Explained

Albert Einstein – physicist, visionary, Nobel Prize laureate and one of the most influential thinkers in the history of science – changed our understanding of the universe forever. Few names stand as strongly for radical thinking, curiosity, and the power of ideas. With his theory of relativity, Albert Einstein challenged the foundations of classical physics and showed that space and time are not fixed quantities. In this extraordinary course – Albert Einstein’s first online course – the theory of relativity is explained simply: clearly, accessibly, and with the subtle self-irony for which Albert Einstein was known. The result is a unique gateway into the ideas of the scientist who revolutionized our view of the universe.

You will learn why space and time are relative and why the speed of light became the central reference point of modern physics. Step by step, Albert Einstein guides you through his famous thought experiments and shows how groundbreaking insights can emerge from seemingly simple questions. You will understand how Albert Einstein’s theory of relativity led to the world-famous formula E = mc² and why it remains one of the most important equations in science. The general theory of relativity is also explained in an accessible way – as the fascinating idea that gravity arises from the curvature of space and time.

Particularly compelling are the insights into the life of Albert Einstein – from the curious student to his revolutionary scientific breakthroughs and the historical events that shaped his research. The course is based exclusively on verified historical sources and was developed in close collaboration with renowned Einstein researchers. It draws on Einstein’s own writings, publications and letters, as well as extensive scientific scholarship that places his ideas and theories in their proper context.

This course is more than an introduction to Albert Einstein’s theory of relativity. It is an invitation to see the world with new eyes. Because once you begin to understand how Albert Einstein thought, you start to realize how fascinating and mysterious our universe truly is.
