- Review topics for the exam (text, updated). For the section entitled, "The Universe: Its Beginning and its Possible Fates", you only need to review the five topics marked as (**).
- How to improve your grades and get extra credit?
(1) If you answer questions correctly and generally participate in class, then you can get extra credit by giving me your name at the end of the lecture. The extra credit (up to 15%) will be added to your final grades. (2) Learn to use the Painter Hall Telescope and ask the training assistant (usually Lara Eakins) to give you a note certifying that you took the trainnig session and are certified to operate the telescope. See details under Course Description. I will give you extra credit if you bring me the note by Mon May 16. (3) Review your homeworks early and come to us EARLY for help on sections that are difficult or unclear to you. Homeworks count for 50% of the total grade and the exams follow the homeworks.
The selected material posted below represent only parts of the lecture, such as figures and a few notes. The main explanations, notes, movies, and demos will be covered only in class where extra credit will be given for participation.

Below are some cool pictures, some taken from my research, that tie in to the questions we are discussing in class
In 2004, as part of HUDF team, we planned and carried out observations lasting one million-seconds of the Hubble Ultra Deep Field (HUDF), the deepest visible-light image ever made of the Universe. These panels (Credit: NASA, ESA, S Beckwith and the HUDF team) from the HUDF reveal the first galaxies to emerge from the so-called "dark ages," the time shortly after the big bang when the first stars reheated the cold, dark universe Almost every panel shows oddball-shaped galaxies engaged in violent interactions with their neighbors and chronicles a period when the universe was younger and more chaotic. Order and structure were just beginning to emerge. The HUDF offers new insights into the origin, structure, and merger history of galaxies as they evolve onto and off the Hubble sequence, and sets constraints on what types of objects reionized the universe long ago.
