Before choosing course

This is a web-based course that provides an introduction to the theory of relativity, which describes the dramatic way in which everyday concepts such as length, time and energy change when traveling at very high speeds, close to the speed of light. As an example, we will study how objects seem to shrink when they move close to the speed of light. Furthermore, we treat other known consequences of the theory of relativity such as the twin paradox, which deals with how the age of two twins is affected by one making a space trip at a very high speed. We will also derive the most famous equation in physics: E = mc2, which describes the relationship between energy and mass. During the course you will see examples that the theory of relativity is not only an abstract theory. It is essential in the construction of modern particle accelerators, and even the modern navigation system GPS relies on the theory of relativity.​

Content and learning outcomes

Course contents

Translations and simple rotations, the notion of invariance in physics, the definition of space and time in Newtonian mechanics, Galileiinvarians, addition of velocitites in Newtonian mechanics, the concepts of inertial and rest frames of reference, Lorentz time transformation, the nature of light and speed, the Michelson-Morley experiment and Lorentzcontractionen, simultaneity, length contraction,  the twin paradox, relativistic kinematics and relativistic reactions.

Intended learning outcomes

After completing the course you should be familiar with basic concepts in both the theory of relativity and the mechanics prior to Einstein, for example, invariance and symmetry, observers and reference frames. You should have gained insight into the contradictions between the Newtonian mechanics and Maxwell's equations that led to the revolution of relativity. You should be able to transform time and space between observer that move relative to each other and realize how these transformations lead to length contraction and tidsdiltation. Realize the connection between mass and energy to have insight in  how relativistic phenomena are exploited in technological applications.
