One-Minute Physics: Why Einstein rotated time

Sandrine Ceurstemont, New Scientist TV

Think it's easy to determine if something is moving? Since position and velocity are relative, it's not always obvious. But when scientists discovered that the speed of light is absolute, it became even more confusing to explain how anything else could move.

In our latest One-Minute Physics episode, animator Henry Reich illustrates how Einstein's special theory of relativity changed our understanding of physics. The video is part of a short series in honour of the famous physicist's birthday, who would have been 133 years old on March 14.
