Ponderings of science, philosophy, history, society, and many other topics
IAI has a brief interview of David Deutsch on his advocacy for the many-worlds interpretation of quantum mechanics. (Warning: possible paywall.) Deutsch has a history of showing little patience with other interpretations, and this interview is no different. A lot of the discussion centers around his advocacy for scientific realism, the idea that science is … Continue reading Many-worlds without necessarily many worlds?
A long standing debate in quantum physics is whether the wave function is real. A quick reminder: quantum entities appear to move like waves, including portions interfering with each other. These waves are modeled with the wave function. But once measured, quantum objects manifest as localized points or field excitations. The wave function can't predict … Continue reading Avoiding the structural gaps
Among my earliest memories are the TV series Star Trek and Lost in Space, two shows that promised a universe teeming with alien life, intelligent life. As a boy, the aliens seemed everywhere. We'd probably find some on Mars and Venus, and there wasn't much doubt we'd find them in other solar systems. And that … Continue reading Where are the aliens?
Scientific realism vs instrumentalism A long standing debate in the philosophy of science is about what our best scientific theories tell us. Some argue that they reveal true reality, that is, they are real. Others that scientific theories are only useful prediction frameworks, instruments useful in the creation of technology, but that taking any further … Continue reading Why I’m an ontic structural realist
As a computational functionalist, I think the mind is a system that exists in this universe and operates according to the laws of physics. Which means that, in principle, there shouldn't be any reason why the information and dispositions that make up a mind can't be recorded and copied into another substrate someday, such as … Continue reading Mind uploading and continuity
What is the relationship between information, causation, and entropy? The other day, I was reading a post from Corey S. Powell on how we are all ripples of information. I found it interesting because it resonated with my own understanding of information (i.e. it flattered my biases). We both seem to see information as something … Continue reading Entropy transformers
Yesterday Daniel Dennett died. He was 82, about the same age as my father when he died a few years ago. I think I've mentioned before that the first writer I read on consciousness was Susan Blackmore. But I know Dennett wasn't far behind, likely based on Blackmore's positive discussions of his work, but also … Continue reading Some thoughts on Daniel Dennett’s ideas
SMBC on how to get access to the secrets of reality. Click through for source and red button caption: https://www.smbc-comics.com/comic/secrets-2 I guess this is philosophical comic sharing week for me. Somewhat related, I've been slowly working my way through Sean Carroll's The Biggest Ideas in the Universe: space, time, and motion. I know a lot … Continue reading How to study reality
What is the difference between magic and science? It's been a while since I shared an Existential Comic. This one gets at a question we've discussed before, although it's been several years. What exactly is the distinction between the physical and non-physical, in this case between science and magic? Credit: https://existentialcomics.com/comic/537 Corey Mohler, the author, has a … Continue reading Existential Comics: the philosophy of magic
It seems like theories that are causally complete are better than ones with gaps. In thinking about this, I'm reminded of a Psyche article I shared a few years ago on fostering an open mind. One of their pieces of advice resonates with an outlook I've had for some time. If embarking on a full-on explanation … Continue reading Causal completeness
