Theoretical Physicists, and the hobbyists and fans who follow at home, all know the physical world is built from a number of beautiful mathematical structures. But why? Why is our reality built on beautiful structures – such as the spherical harmonics underlying electron orbitals, or even simpler things like the fundamental theorem of calculus? Shouldn’t […]
Your brain acts like a computer. How would you like the ability to kill any processes that you’d rather not have running? I developed a technique to do exactly this while recovering from a series of manic episodes that lead to intense, unwanted paranoia. One of the difficult things about dealing with delusions is that […]
Sleep is a Computational Technique The best evidence that our brains are computers is what happens when we sleep. Our reasons for sleeping are explained in ‘Why We Sleep’, by Dr. Matthew Walker, the Director of the UC Berkeley Center for Human Sleep. It’s an excellent read, and it has encouraged me to take sleep far […]
I think from first principles. I can translate every aspect of my experience – including the messy, emotional, human bits – into physics and mathematics. What follows is my faith. I believe that I am a locus of conscious experience, in which appear shadows of a massive mathematical structure that contains all possible states of […]
The first time I heard the idea that roads should be privatized, I had the reaction most people do: “How on earth would that even be possible?” “You’d need to have cameras all over the place, and each of these companies would have to keep track of how far you drove on which road, at […]
We recently potty-trained our three year old daughter. This process was a great chance to integrate my understanding of predictive processing with a real life case of personal growth. Potty training a child is also a great example of how understanding yourself as a computational system can help you achieve your own personal growth. One […]
I watched myself make a choice the other night. It was fascinating. Earlier that afternoon, I was at the park with my daughter. I’d brought her some goldfish crackers as a snack. While she finished them, I picked out two, and ate them. I don’t normally eat that kind of food, but they were right […]
A common belief among rational, materialist adults is that faith is destructive. People like Sam Harris and Richard Dawkins argue that all of our beliefs should be based on reason and evidence. By ignoring reason and evidence, they argue, faith allows people to believe all kinds of destructive falsehoods that end up having strongly negative […]
The ability to simulate other computational systems is incredibly powerful. When a human mentally simulates a machine, we call it debugging or reasoning. When a human mentally simulates another human, we call it empathy. Yet in both cases, the process is the same: a computational system (human or machine) models and predicts the behavior of […]
The predictive processing model of whole brain function gives a pretty good explanation for why the advice “show it, don’t tell it” works so well. When you tell someone, you’re giving them a higher level narrative, which ostenbily generates sensory predictions. These sensory predictions don’t necessarily line up with the current observed sensory inputs, and […]
