The Many Hidden Worlds of Quantum Mechanics

By: Sean Carroll, The Great Courses

Narrated by: Sean Carroll

In a field known for startling ideas, the Many-Worlds Interpretation (MWI) of quantum mechanics may take the prize. It holds that parallel to our own world are a large number of other universes, almost identical to ours but with small variations. Copies of each of us inhabit a myriad of these worlds. But they are not us exactly; they share our past history, but they are different people who have unique futures. Although these realms are invisible and can’t communicate with each other, prominent physicists are convinced they must exist.

The Many Hidden Worlds of Quantum Mechanics is about why we should take the Many-Worlds Interpretation seriously, as arguably the best explanation of quantum mechanics, the science of matter and energy at the atomic and subatomic scales. In 24 fascinating lectures, Professor Sean Carroll of Johns Hopkins University guides listeners through the history, reasoning, and implications of this bold idea. He also covers alternate theories to Many-Worlds and unresolved questions in fundamental physics, making the course a thorough introduction to the current state of this exciting field.

Starting with classical physics, Professor Carroll explains how quantum theory overturned traditional ideas about matter and energy in the early 20th century. A consensus soon formed around a framework called the Copenhagen Interpretation, which rejected speculation about what was “really happening.” The Many-Worlds Interpretation in the 1950s was a reaction against this view, proposing that we take the basic equation of quantum mechanics seriously and go where it leads. It turns out it leads to Many-Worlds.

The course also covers quantum computing, quantum gravity, the resolution of quantum paradoxes, and speculation about whether human consciousness plays a central role in quantum experiments (Many-Worlds argues it doesn’t). Even die-hard skeptics of Many-Worlds will learn much from these lectures and will have their beliefs tested by a theory that is both mind-boggling and mathematically elegant.

Good introduction to the many world theory.

Good introduction for someone new to the many worlds theory.Enjoyed the book thoroughly.Definitly recomended for someone who wants to learn more.

Exceptional, must read

Anyone who had a pleasure of studying physics, astronomy, astrophysics, quantum thermodynamics dynamics, black holes, biology, calculus, string theory, big bang theory, and any other closely related disciplines will find this book extreamly fascinating, although with all the listed accomplishments this book will still blow your mind. It should be read at least twice to appreciate the depth of the narrative.

Excellent presentation

Dr Carroll delivers an easy to follow and engaging explanation of this subject matter. His inclusion of relevant and significant historical events fosters an appreciation for the key characters and their contributions. His language, delivery, and thoughtful regard for the scientific and philosophical implications of quantum mechanics makes this collection of lectures an absorbing experience for anyone interested in learning about our fundamental reality.

Sean Carroll always has such amazing content

Worth listening to this book as well as his Mindscape podcast. He creates the best popular science content I’ve ever come across.

Love the book & narration, hate the intermezzos

Great book, well narrated. But the intermezzos with the random guy and music just break the flow and sound idiotic.
