Angus Menuge on the mind–body problem: It’s like developing and then writing down an idea

It would be a very poorly designed system if, every time we wanted to raise our arm, we’d have to know how to adjust each and every molecule in our arm or what specific pattern of nerve signals we would have to send. Well, then we’d be unable to act. And likewise, if what matters is that I don’t stub my toe again, all I’ve got to remember is, don’t push your toe like that rather than worrying about how I did it this time. Because the odds are, I’d never do the same physical movement again. Read More ›

What has information theory to say about talking to spiders?

There's a way we can do that, provided the spider has anything to say. One of the presentations at the American Chemical Society’s Spring 2021 meeting featured an algorithm that makes music from the analysis of spiders’ webs. Read More ›

Gregory Chaitin asks, if the universe is information, not matter, does that help explain consciousness?

Chaitin: The normal view if you dabble in metaphysics is that the universe is made from mathematics. That’s a Pythagorean idea, that God is a mathematician. And I prefer to say God is a … a computer programmer or a programmer. Read More ›

C. Elegans (roundworm) perceives color without eyes

At The Scientist: The new results show that the worms are “actually comparing ratios of wavelengths, and using that information to make decisions,” he says. “And that, I think, was completely surprising and unexpected.” … Read More ›

Rob Sheldon weighs in on the fundamental building blocks of nature – particles, fields, or …

Sheldon: It is curious that the author of this Aeon article has frozen Wheeler at his second stage, neglecting to mention his final conclusion. Read More ›

Does communication between predator and prey shape evolution?

Fascinating info about snakes’ warning signals but the author ends up defending dumb Darwinism which, increasingly, complicates explanations. One must come up with a Darwinian explanation for things instead of just reporting and learning from them. Or asking what the information probability is, for this type of change. Read More ›

At Forbes: Hawking’s black hole paradox is NOT solved

Ethan Siegel looks at the limitations: But we’re still a long way away from determining exactly where that information goes, and how it gets out of a black hole. Theorists disagree over the validity and soundness of many of the methods that are currently being employed to do these calculations, and no one has even a theoretical prediction for how this information should be encoded by an evaporating black hole, much less how to measure it.

Jonathan Bartlett: Elon Musk inadvertently tumbles to a big problem in origin of life theory

Bartlett: Indeed, whatever the difficulty of creating life in the lab, making individual prototypes is not nearly as problematic as making “the machine that makes the machine,” which all reproducing living cells can do. That is, the ability of an organism to reproduce is at least an order of magnitude harder that the ability of an organism to just live. Read More ›
