Lecture 17Play Video |
The Einstein Podolsky Rosen (EPR) Paradox: A simple explanationThis video responds to a question about the EPR Paradox. It is explained in simple terms (no maths) but requires knowledge of some of the basics of Quantum Mechanics in my other videos. Too simple for experts! |

Lecture 18Play Video |
Bell's InequalityA basic introduction to Bell's Inequality which shows that there cannot be hidden variables (a form of inbuilt DNA), as postulated by EPR, to explain how entangled particles behave. |

Lecture 19Play Video |
Schrodinger's CatA description of Schrodinger's thought experiment (no cats were harmed) which along with EPR challenged the emerging thinking of quantum mechanics in 1935 |

Lecture 20Play Video |
Standing (Stationary) WavesThe disctinction between standing and traveling waves; a demonstration of how standing waves are formed; and their application to quantum physics. |
