This Scientific American video, shared by Aeon, is pretty good if you're looking for a quick basic primer on quantum computing. It's short, less than nine minutes. Although I do have a beef which I'll discuss below. https://www.youtube.com/watch?v=uLnGp1WTNFQ Decoded: How Does a Quantum Computer Work? The beef, which is pretty common with popular explanations of … Continue reading Decoded: How does a quantum computer work?
The function of qualia
Often when I mention that I'm a functionalist in terms of the mind, someone references the Stanford Encyclopedia entry on functionalism. Strange to say, but I've never gone through that entire entry. This week I poked around a little in it, mostly in the objections section. Most of the objections either strike me as more … Continue reading The function of qualia
Universal functionalism
In one of the final chapters of his book: Reality+: Virtual Worlds and the Problems of Philosophy, David Chalmers asks, have we fallen from the Garden of Eden? "Eden" in this case is a metaphor for living in a world where everything is as it seems, matching our pre-theoretical view of reality. In Eden, everything exists … Continue reading Universal functionalism
Can consciousness be simulated?
David Chalmers in his book: Reality+: Virtual Worlds and the Problems of Philosophy, eventually gets around to addressing the 800-pound gorilla in the room for any discussion of the simulation hypothesis. Can consciousness itself be simulated, and if so, would the resulting entity be conscious? This issue, I think, is what makes many react with far sharper … Continue reading Can consciousness be simulated?
Information, computation, and reality
David Chalmers in his book: : Reality+: Virtual Worlds and the Problems of Philosophy, has a discussion on information and reality. He identifies different types of information: semantic, structural, and symbolic. Semantic information is what we colloquially think of as information, it's the patterns that tell someone or something about reality. A map of a city … Continue reading Information, computation, and reality
Century Rain
Recently I recommended Alastair Reynolds' new book Inhibitor Phase. In subsequent conversation with Wyrd Smythe, I remembered that there were a couple of books in Reynolds' backlist that I had missed. One of these is Century Rain, a novel that, based on Wyrd's assessment, was definitely worth reading. Century Rain is a standalone novel, one … Continue reading Century Rain
Many-worlds and Bell’s theorem
Sean Carroll's February AMA episode is up on his podcast. As usual, there were questions about the Everett many-worlds interpretation of quantum mechanics (which I did a new primer on a few weeks ago). This time, there was a question related to the correlated outcomes in measurements of entangled particles that are separated by vast … Continue reading Many-worlds and Bell’s theorem
Criteria for being real
David Chalmers in his new book: : Reality+: Virtual Worlds and the Problems of Philosophy, takes the philosophical stance of virtual realism. As I understand it, virtual realism is the thesis that virtual reality is genuine reality, with emphasis especially on the view that virtual objects are real and not an illusion. In general, “realism” is … Continue reading Criteria for being real
Can we know if we’re in a simulation?
I'm currently making my way through David Chalmers' new book: Reality+: Virtual Worlds and the Problems of Philosophy. Chalmers explores the simulation hypothesis, using it as a portal into a wide ranging selection of philosophical issues, including discussions on God, information theory, structuralism, and a lot of other topics I haven't gotten to yet. His … Continue reading Can we know if we’re in a simulation?
Complex life may be more rare in the universe than we thought
Quanta has a pretty interesting article up today: A Solution to the Faint-Sun Paradox Reveals a Narrow Window for Life. Our understanding of the physics of the sun indicate that it should have been only 70% as bright as it is today. But if so, early Earth should have been a snowball not really capable … Continue reading Complex life may be more rare in the universe than we thought
