The Life of Psi: More on the Superpositi...

In this first lecture, David Wallace examines the justification for interpreting the superposition states as multiplicities. 

In the third lecture, David Wallace asks how we make sense of probability in the Many-Worlds theory. 

In the fourth lecture, Harvey Brown asks why real-world events always proceed in the direction of increasing entropy, even though the laws of physics don’t require it. 

First lecture of the Quantum Mechanics course given in Michaelmas Term 2009. 

Second lecture in the Philosophy of Religion lecture series. 

From electrons behaving as both particles and waves to a cat in a box that’s both dead and alive, the consequences of quantum physics are decidedly weird. So strange, that over a century since its conception, scientists are still arguing about the best way to understand the theor ... Show More

An examination of some more advanced concepts of quantum mechanics, focusing on describing Dirac's bra-ket formulation of quantum theory. I discuss the formulation of quantum mechanics in terms of vectors in Hilbert spaces, Hermitian operators as corresponding to observables, ort ... Show More

A short introduction to Astrophysics at Oxford University by Professor Roger Davies. 

It has been over a century since the groundwork of quantum physics was first formulated and yet the strange consequences of the theory still elude both scientists and philosophers. Why does light sometimes behave as a wave, and other times like a particle? Why does the outcome of ... Show More

Quantum mechanics is full of weird findings – for example, that systems widely separated can somehow still be correlated, and that a system may be in two different possible states at the same time. Entanglement and superposition, among other phenomena, have prompted debate since ... Show More

First lecture in the Philosophy of Religion Lecture series. 

Part 2.1. A brief recap on the first lecture describing how Aristotle's view of the universe, dominant throughout the middle ages in Europe, came to be gradually phased out by a modern, mechanistic view of the universe.
