Quantum Entanglement Bell Tests Part 1: Bell's Inequality (My Best Explanation)

If you want a really good explanation of Bell's inequality, and how it can be applied to an experiment, then (hopefully) you should not need to look any further. After watching other videos on this topic I felt the need to make my own. I'll keep my eyes on the ratings to see if you agree that this video is worthwhile. Thank you for visiting my channel; I hope you'll find my other videos entertaining.

The other four videos in this series will be published over the four days following this one. See overviews below...


Part 2: How QM Became Mainstream (1st Bell Test)    • Quantum Entanglement Bell Tests Part 2: Ho...  

Discover how the first Bell test experiment transformed quantum mechanics from being a fringe subject to being accepted as part of mainstream physics. The very nature of reality had been called into question, but was this justified? The evidence appeared convincing at the time, but could it be that it was not scrutinized thoroughly enough because almost everyone secretly wanted it to be true?


Part 3: The CRAP Loophole    • Quantum Entanglement Bell Tests Part 3: Th...  

The first 3 'loophole-free' Bell test experiments were published within 3 months of each other in 2015. They claimed to have confirmed spooky action at a distance by covering all the most plausible loopholes. But by using quantum random number generators instead of using algorithms, had they simply created a completely new loophole?


Part 4: Delft – The 1st Loophole-free Bell Test    • Quantum Entanglement Bell Tests Part 4: De...  

It was said to be the experiment that finally confirmed spooky action was real. It was claimed that the 80-year old debate was over; Einstein was declared to be wrong and Bohr was supposedly right! But how convincing was the result of this experiment? Was it really undeniable proof?


Part 5: Has Proper Science Been Abandoned?    • Quantum Entanglement Bell Tests Part 5: Ha...  

It is not easy to construct a loophole-free Bell test experiment. The scientists don't tell us about how changing any particular part of such a complicated experiment would affect the result. But isn't this exactly what the scientists should be telling us? Instead they compete among themselves to see who can produce the most impressive violation of a Bell inequality. Has proper drill-down scientific investigation (to identify a cause) been abandoned?
