Have you ever wondered what the often repeated equation E=mc2 really means? Have you wondered about why it is claimed that Einstein’s theory of Special Relativity says that moving clocks tick more slowly than stationary clocks? Or that space undergoes contraction in the direction of travel according to Special Relativity?

If so, and if you have been looking for an easy way to grasp the meaning of Special Relativity with a minimum of complicated mathematics, then this is the app for you. The focus of this app is to make the important points of Einsteins Special Relativity theory accessible to the non-scientist by emphasizing thought experiments and simple reasoning. Chapters cover topics such as:

• Why “time dilation” occurs
• Why the length of an object depends on the speed of an observer
• The “Ladder and Barn” paradox
• Is faster than light travel possible according to Special Relativity?
• The meaning of the equation E=mc2
• The “wall of clocks” approach to visualizing space-time
• Space-Time diagrams
