"Mysteries of Modern Physics: Time" Prof. Sean Carroll (DVD) (24 Lectures / 30 Minutes Per Lecture /  4x DVD - The Great Courses)
Time remains the most familiar yet baffling dimension of our existence, an unrelenting flow that dictates every aspect of reality. In "Mysteries of Modern Physics: Time," Professor Sean Carroll—a theoretical physicist at the California Institute of Technology—interrogates the fundamental asymmetry between the past and the future. The core of this study focuses on the Second Law of Thermodynamics and the concept of entropy, investigating why time appears to move in a single direction despite the reversible nature of physical laws. You will grapple with the "arrow of time," exploring how the low-entropy state of the Big Bang essentially authored the history of the universe.
 
The inquiry ventures deep into the cosmic and subatomic realms, where relativity and quantum mechanics shatter our intuitive perceptions of the present moment. Professor Carroll navigates the profound implications of black holes, the expansion of space, and the theoretical feasibility of time travel, providing a map for the most complex landscapes in modern science. These lectures create a dialogue between rigorous mathematical models and enduring philosophical questions, proving that time is not just a background clock but a dynamic player in the evolution of the universe. By the final lecture, you will see the cosmos as a vast, interconnected tapestry woven by the laws of physics, offering a definitive look at the dimension that defines our journey through the stars.
