Bell’s inequality is both incredibly simple and incredibly powerful, and speaks to the fundamental nature of reality; it will be the focus of this blog. So what is Bell’s inequality? It was derived by John Stewart Bell in the 1960s, and has now been tested by experiments. The following derivation is based on work by…

These two pictures hold an incredible mystery for reality. They demonstrate clearly that quantum particles (we are all made from atoms, and therefore quantum particles), have a very different reality to our classical intuition. The picture below shows the arrangement of a relatively simple experiment: a source of light from (S), impacts a beam splitter…

This is the first post from this new website. The topic will be Reality, and what it really is. So Young’s double slit experiment with monochromatic light, results in the characteristic bright and dark bands of light on the screen, which form as a consequence of the interference of the diffracted light from each slit.…
