(Scientific) Ghost Busters

A couple of days ago there was a YouTube feed for me recommending a clip in which Richard Dawkins was interviewed by Piers Morgan. Now, my readers will almost certainly know who Dawkins is, however, they may not be familiar with Morgan (best leave it at that 😊).

Duane the Man

Lots of my writing emphasises the consistency and coherence of scientific explanations across the board. For instance, to take an almost random example, the Victorian physicists had a problem with Darwin’s theory of evolution because Kelvin’s estimate for the age of the Earth was too inaccurate.

How Newton invented Hidden Variables and Fresnel discovered Decoherence

I’d like to tell you something you might find surprising (I did) and it’s all about things in classical physics that happen to be analogous to some of the concepts frequently thought to be strictly quantum mechanical.

Weak Measurements and Consciousness

I’ve been writing a great deal about quantum measurements and the fact that, in quantum physics, they are basically entangling operations. No need for collapse postulates or any non-linear modifications to the unitary dynamics. No quantum jumps or any other discontinuities.

Occasionalism and Quantum Entanglement

Quantum physics is frequently viewed as violating the law of causality, namely that the same causes ought to produce the same effects. If I drop a ball from rest from a certain height, it will always reach the ground in the same amount of time, and with the same terminal speed. No matter how many times we repeat this experiment (and Galileo had done it till he was blue in the face) we will never obtain – to within an experimental error – a different result. The same initial conditions always produce the same final outcomes in classical physics.

Quantum Physics: Consistent and Complete

If you watch various online quantum discussions these days you will most likely hear two statements being repeated frequently. One is that quantum physics is inconsistent. And the other one is that it is incomplete. I’d like to discuss each in turn and convince you that, in fact, neither of them is true.
