 On
Wednesday, February 14 (Valentine's Day) we will have our
midterm exam during the regular class period. The exam will be
comprehensive and will include everything discussed in class up to and
including material from February 9 (but primarily the first 4 topics,
and everything on the first 3 homeworks).
I also strongly recommend
you read Ryden Chapters 17. Some of the more important
topics we've covered include:
 The Cosmological Principle
 The Friedmann Equation
 Cosmological Models
 Comoving,
proper, angular, and luminosity distances
 Observations in a
curved universe
 Cosmological tests
 Measuring fundamental
parameters (how? what they mean? what are the accepted values?)
This list is
not comprehensive. The exam will consist of 34 problems similar in style
to those I've given you on the homework. Be aware that in past
years, we've had 2x 1 1/2 hour lectures, but this year, our
lectures are only an hour. As a result, the exam will be slightly
shorter than in the past. As a help, please take a
look at some old exams:
 [2014 Midterm]
 [Solution Key]
 [2016 Midterm]
 [Solution Key]
Except for the equation sheet, below, the exam will be
entirely closed book. You may bring a calculator, but are expected to
use it only for basic arithmetic (addition, subtraction,
multiplication, division) only.

 On
Wednesday, March 21 we will have our final exam from
3:305:30pm in Curtis 452 (Please make sure you know where that is
ahead of time). As with the midterm, the exam will be
comprehensive and will include everything discussed in class.
I also strongly recommend
you review all of Ryden, with particular attention given to the
sections outlined in the course syllabus (above). Some of the more important
topics we've covered since the midterm include:
Except for the equation sheet, below, the exam will be
entirely closed book. Again, you may bring a calculator, but are expected to
use it only for basic arithmetic (addition, subtraction,
multiplication, division) only.
[Equation Sheet]  As always, if you are the first to find an error, let me know, and you'll get extra credit.
