The psychology of belief

Many years ago I wrote an article called belief explained. You can find a 2007 version of it on a website called scienceforums.net. A development of that was an article called the psychology of belief. You can find a 2010 version of that on a forum called ILovePhilosophy.com. I wrote it because way back in about 2006, I realised that I believed in things for which there was no scientific evidence at all. I don’t just mean things like religion and politics. I mean things in…

Quantum entanglement is scientific fraud

The quantum entanglement story began in 1935 with the EPR paper. That’s where Einstein, Podolsky, and Rosen said quantum mechanics must be incomplete, because it predicts a system in two different states at the same time. Later that year Bohr replied saying spooky action at a distance could occur. Then Schrödinger came up with a paper where he talked of entanglement, a paper where he used his cat to show how ridiculous the two-state situation was, and a paper saying he found spooky action at a…

Quantum entanglement history I

The 2022 Nobel prize in physics was awarded to Alain Aspect, John Clauser and Anton Zeilinger "for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science". Hamish Johnston gave a brief account in Physics World on October 4th. He said the three laureates performed the key experiments that established the quantum property of entanglement. That’s quantum entanglement, which is often described as spooky action at a distance. The idea is that you produce two photons from one event, and when…

The double slit experiment

There’s a nice little physicsworld article dating back to 2002. It was written by then-editor Peter Rodgers, and it started by asking “What is the most beautiful experiment in physics?” The answer was, of course, the double slit experiment, which was first performed by Thomas Young in 1801: Double slit experiment image from the curiosity makes you smarter article by Ashley Hamer People refer to the double slit experiment as an example of the weirdness of quantum physics. Or to promote weird ideas such as the…
