Ponderings of science, philosophy, history, society, and many other topics
Last week, Sabine Hossenfelder did a video and post which was interesting (if a bit of a rant at times at strawmen) in which she argued for a little considered possibility in quantum mechanics: superdeterminism. In 1935, Einstein and collaborators published the famous EPR paradox paper, in which they pointed out that particles that were … Continue reading Superdeterminism and the quandaries of quantum mechanics
I recently completed Anil Seth's new book, Being You: A New Science of Consciousness. Seth starts out discussing David Chalmers' hard problem of consciousness, as well as views like physicalism, idealism, panpsychism, and functionalism. Seth is a physicalist, but is suspicious of functionalism. Seth makes a distinction between the hard problem, which he characterizes as … Continue reading Anil Seth’s theory of consciousness
In last week's post on entropy and information, I started off complaining about the most common definition of entropy as disorder or disorganization. One of the nice things about blogging is you often learn something in the subsequent discussion. My chief complaint about the disorder definition was that it's value-laden. I asked: disordered according to … Continue reading Reconciling the disorder definition of entropy
I've posted a lot over the years on interpretations of quantum mechanics. My writing has tended to focus on comparing the big three: Copenhagen, pilot-wave, and many-worlds. But there are a lot of others. One that has been gaining converts among physicists and others is Carlo Rovelli's relational quantum mechanics (RQM) interpretation. This is an … Continue reading Carlo Rovelli’s Helgoland
Philosopher Jonny Thompson has an article up on RealClearScience profiling the views of Mary Midgley: The Three Myths of Scientism. (Warning: the RealClearScience site is pretty ad intensive.) Midgley was a famous critic of views she regarded as scientism, and often sparred with atheist and antitheist Richard Dawkins. As someone who usually takes the scientific … Continue reading The relativity of scientism
In the scientific realism vs instrumentalism debate, realism is the position that the elements of a scientific theory represent reality. So when general relativity talks about space warping, space really is warping. Instrumentalism, or anti-realism, is the stance that scientific theories are just prediction mechanisms, with no guarantee that they represent reality. Under instrumentalism, general … Continue reading Structural realism, a way to be a scientific realist?
The recent news reports that cuttlefish are able to pass the marshmallow test are interesting. The classic marshmallow test involved giving a young child a marshmallow but promising them a second one if they could hold off eating the first for 15 minutes. The kid was then left alone in a room with the first … Continue reading The marshmallow test and conscious feeling
Scott Aaronson posted an interesting piece this week coming out about his favorite interpretation of quantum mechanics. I think the most relevant part is this snippet. (Although the full piece has a lot of nuance well worth reading.) I don’t mean to say that the interpretations are all interchangeable, or equally good or bad. If … Continue reading An instrumentalist Everettian
I recently finished Mark Solms' new book, The Hidden Spring: A Journey to the Source of Consciousness. There were a few surprises in the book, and it had what I thought were strong and weak points. My first surprise was Solms' embrace of the theories of Sigmund Freud, including psychoanalysis. Freud's reputation has suffered a … Continue reading Mark Solms’ theory of consciousness
This post is about an aspect of the Everett many-worlds interpretation of quantum mechanics. I've given brief primers of the interpretation in earlier posts (see here or here), in case you need one. Sean Carroll, as he does periodically, did an AMA on his podcast. He got a number of questions on the Everett interpretation, … Continue reading The nature of splitting worlds in the Everett interpretation
