About this video
In this video, we explore Bell's legendary 1964 paper in full technical detail, to explore the glitch in reality that he unveiled unto the world, which has been troubling physicists and philosophers ever since. This video is a sequel to my video on the EPR paper (just as Bell's 1964 paper is a sequel the 1935 EPR paper), so I recommend checking out that video first, unless you're already familiar with EPR.
Here's a link to Bell's 1964 paper "On the Einstein Podolsky Rosen Paradox":

And while we're at it, here’s the link to the 1935 EPR paper:
