## Relativity

**Relativity (Spring 2007, Stanford Univ.)**. Instructor: Professor Leonard Susskind. This course takes a deeper look at relativity.
Most of the course focuses on Einstein's special theory of relativity. General relativity is introduced in the last few lectures.

**Note**: Relativity (Spring 2007) - videos are mistakenly titled Quantum Entanglements Part 3.
"Quantum Entanglements Part 3" is in fact a lecture series on special relativity and electromagnetic theory, and the order in which the lectures were given is
1, 4, 5, 6, 7, 2&3, 8 and 9 (in terms of the numbers given on the videos)

Lecture 1 | Relativity (Spring 2007)The general notion of relativity, Galilean relativity, Principles of special relativity, Lorentz transformations. |

Lecture 2&3 | Relativity (Spring 2007)Field equations, Maxwell's equations, Charge and current, Electromagnetic laws of motion. |

Lecture 4 | Relativity (Spring 2007)Lorentz transformations continued, Space-time separation, Time dilation, Length contraction, Space versus space-time. |

Lecture 5 | Relativity (Spring 2007)General transformations, Composition of velocities, Four-vectors, Proper velocity and momentum. |

Lecture 6 | Relativity (Spring 2007)This lecture is about how the laws of nature have to be written in terms of tensors if we want them to be the same in all reference frames, the basic requirement of relativity. |

Lecture 7 | Relativity (Spring 2007)Lorentz force law, Magnetic cross product, Relativistic Lorentz force, Wave equations. |

Lecture 8 | Relativity (Spring 2007)Flat space, Curved space, Introduction to cosmology, Cosmological space-time, Hubble's constant. |
