# ASTR 3740 Relativity & Cosmology Spring 2000: Syllabus

ASTR 3740 Spring 00 Homepage

### Grading

Grading will be weighted as follows:

Item | Date | Weight |
---|

Problem Sets | | 3/6 |

Midterm | Fri 11 Feb | 1/6 |

Midterm | Fri 10 Mar | 1/6 |

Final | 4.30-7.00pm Mon 8 May | 2/6 |

If you add that up, it comes to 7/6.
To make it add to 100%, I will delete the worst 1/6 of your score.
That means you can do badly on 2 problem sets, or on 1 of the midterms,
or your final will count only half.

The plan is to have 5 or 6 problem sets, roughly one every two weeks.
The problem sets will be mostly mathematical.

### Summary Sessions

There will be summary sessions in class on Wed 9 Feb and Wed 8 March,
the classes before the midterms.

### Fiske Planetarium

CU's Fiske Planetarium has been reserved
at the usual class time on the days in the following table.
These shows are part of the course
- exams may cover material presented in these shows.

Show | Date |
---|

Black Holes and Relativity 1 | Mon 21 Feb |

Black Holes and Relativity 2 | Fri 25 Feb |

The Milky Way | Mon 20 Mar |

Galaxies 1 | Fri 7 Apr |

Galaxies 2 | Wed 12 Apr |

The Big Bang 1 | Fri 21 Apr |

The Big Bang 2 | Mon 1 May |

### Content

Special Relativity (3 weeks)
- Motivation, axioms
- Spacetime diagrams, 4-vectors, Lorentz transformations, time dilation, Lorentz contraction, simultaneity (per
Special Relativity)
- Relativistic travel - what things actually look like
- Energy-momentum

General Relativity (3 weeks)
- Motivation, axioms
- General covariance, metric, geodesics, curvature, Einstein's equations
- Black Holes - theory (per
Falling into a Black Hole)
- Black Holes - observation

Cosmology (6 weeks)
- The Milky Way
- Galaxies
- Expansion of the Universe, geometry, Friedmann equation, horizons
- Cosmic Microwave Background
- Dark Matter
- Inflation

There are 15 weeks of class time (30 lectures), excluding the
March Spring Break, so the above schedule leaves 3 weeks
for summary sessions, exams, going over problem sets, etc.
