» 8.284 Modern Astrophysics, Spring 2006
Lecture. This course explores the applications of physics (Newtonian, statistical, and quantum mechanics) to fundamental processes that occur in celestial objects. The list of topics includes Main-sequence Stars, Collapsed Stars (White Dwarfs, Neutron Star...
» Astrophysics I
Lecture. This course provides a graduate-level introduction to stellar astrophysics. It covers a variety of topics, ranging from stellar structure and evolution to galactic dynamics and dark matter.
» Astrophysics II
Lecture. This is the second course in a two-semester sequence on astrophysics. Topics include galactic dynamics, groups and clusters on galaxies, phenomenological cosmology, Newtonian cosmology, Roberston-Walker models, and galaxy formation.
» Atomic and Optical Physics II
Lecture. This is the second of a two-semester subject sequence beginning with Atomic and Optical Physics I (8.421) that provides the foundations for contemporary research in selected areas of atomic and optical physics.? Topics covered include?non-classica...
» Classical Mechanics
Lecture. This class provides a formal introduction to classical mechanics, Euler-Lagrange equations, Hamilton\'s equations of motion used to describe central force motion, scattering, perturbation theory and Noether\'s theorem. The course also extends to?c...
» Cosmology
Lecture. This course provides an overview of astrophysical cosmology with emphasis on the Cosmic Microwave Background (CMB) radiation, galaxies and related phenomena at high redshift, and cosmic structure formation. Additional topics include cosmic inflati...
» Course Introduction and NewtonianMechanics
Lecture. Professor Shankar introduces the course and answers student questions about the material and the requirements. He gives an overview of Newtonian mechanics and explains its two components: kinematics and dynamics. He then reviews basic concepts in ...
» Dark Energy and the AcceleratingUniverse and the Big Rip
Lecture. Class begins with a review of the mysterious nature of dark matter,which accounts for three quarters of the universe. Different models ofthe universe are graphed. The nature, frequency, and duration ofsupernovae are then addressed. Professor Baily...
» Dark Matter
Lecture. This lecture introduces an important concept related to the past andfuture of the universe: the Scale factor, which is a function of time.With reference to a graph whose coordinates are the Scale factor andtime, the problem of dark matter is addre...
