The Philosophy of Quantum Theory
About the Course
In the early 20th century, certain observations were made that seemed to contradict the model given by classical physics. These new observations eventually gave rise to a new and controversial interpretation of reality: the Copenhagen Quantum Theory.
Why did Einstein claim that God didn’t play dice? What does it mean for two particles to be in an entangled state? Is the world necessarily deterministic, or is it possible that some processes are truly random? What is spooky action-at-a-distance, and how was it proved with simple maths? Can the measurement of a result affect the result itself? Is an electron a particle, a wave, or both?
NYU philosopher of science and author of The Metaphysics of Physics looks at the experiments of the early quantum physicists and the letters they exchanged, in order to provide a coherent and easy-to-understand history of quantum theory, and evaluate the many interpretations it has spawned.
By the end of the course, you will have learned:
• why Einstein implored fellow scientists to ‘try to hold on to physical reality’
• why you can never prove that physics is indeterministic
• what it means for something to be ‘quantized’
• what exactly the double slit experiment showed
• what Schrodinger’s Cat was meant to rule out
• how the many-worlds theory negates the concept of probability
As part of the course there are in-video quiz questions to consolidate your learning, suggested further readings to stimulate a deeper exploration of the topic, discussion boards to have your say and an end-of-course assessment set by Tim Maudlin.
IAI Academy courses are designed to be challenging but accessible to the interested student. No specialist knowledge is required.
About the Instructor
Tim Maudlin is professor of philosophy at New York University and a world-leader in the field of philosophy of physics. He is the author of the recently published Philosophy of Physics: Quantum Theory and made his name studying the mysterious behaviour of entangled quantum particles. Maudlin warns that we should be wary of physical theories that contradict our direct impression of reality, especially when it comes to the nature of time.
Part One: The Problem of Non-LocalityEinstein famously disputed some of quantum theory’s findings, claiming that God does not play dice with the universe. Here Maudlin reviews the arguments and ideas that have since stemmed from that debate.
Part Two: Making Sense of Quantum TheoryHow can experiments not have a single unique outcome, such as Schrödinger’s cat ending up dead or alive? Hear Maudlin’s take on the “Measurement Problem” and what it really means.
