Unexplained — Maybe Unexplainable — Numbers Control the Universe

For example, brilliant physicist Richard Feynman called 1/137, the fine structure constant, “a magic number that comes to us with no understanding by man”

In Carl Sagan’s Contact, the extraterrestrials embedded a message in the irrational number pi (the circumference of a circle divided by its radius). But some other numbers are critical to the structure of our universe too — and why they are critical does not make obvious sense. ➤ Perhaps the most fundamental and mysterious one is the fine structure constant of the universe: A seemingly harmless, random number with no units or dimensions has cropped up in so many places in physics and seems to control one of the most fundamental interactions in the universe. Its name is the fine-structure constant, and it’s a measure of the strength of the interaction between charged particles and the electromagnetic force. The current Read More ›

Quick Facts on IIT (the Leading Theory of Consciousness)

IIT may be part of a trend in science in which emergence and panpsychist theories are slowly replacing materialist and physicalist ones

Consciousness, as a concept, is so easy to experience and so hard to define. Or explain. The most popular current theory of consciousness is Integrated Information Theory (IIT), pioneered by neuroscientist Giulio Tononi and championed by Allen Institute neuroscientist Christof Koch. For the purpose of discussing IIT, science writer Mike Hogan works with this definition: Consciousness for purposes of this theory is defined as ‘self-awareness’ or the Central-Identity; the inner-voice that allows your brain to talk to itself, an awareness that ‘you’ exist, the rationalization of your own relevance to that existence, and an awareness of the cause and effect of your actions in regard to yourself and your environment.
