The dimensional aspect of existence is associated with the dimensions of space and time.

Posted by in categories: cosmology, evolution, information science, materials, neuroscience, particle physics, quantum physics, singularity, space

The dimensionless aspect, since it has no dimensions, is outside of space and time. This is the key aspect to existence: an aspect outside of space and time perpetually interacting dialectically with an aspect inside space and time. All of the weird and wonderful phenomena of the universe are the products of this ultimate dichotomy.

Does this sound crazy? Then consider the evidence provided by black holes.

The R = 0 Universe.

Single photon decision-maker solves multi-armed bandit problem

Posted by in categories: computing, information science, particle physics, quantum physics

https://en.wikipedia.org/wiki/Multi-armed_bandit

In probability theory, the multi-armed bandit problem (sometimes called the K- or N-armed bandit problem) is a problem in which a gambler at a row of slot machines (sometimes known as “one-armed bandits”) has to decide which machines to play, how many times to play each machine and in which order to play them. When played, each machine provides a random reward from a distribution specific to that machine. The objective of the gambler is to maximize the sum of rewards earned through a sequence of lever pulls.


(Phys.org)—A combined team of researchers from France and Japan has created a decision-making device that is based on basic properties of quantum mechanics. In their paper published in Scientific Reports (and uploaded to the arXiv preprint server), the team describes the idea behind their device and how it works.

Is Quantum Space-Time a Scale-Free Network Like Facebook?

Posted by in categories: neuroscience, quantum physics, space

Researchers from Queen Mary University of London and Karlsruhe Institute of Technology have developed a model that applies ideas from the theory of complex networks, such as the brain or the Internet, to the fundamental quantum geometry of space-time.

The research is published in Scientific Reports with the title “Complex Quantum Network Manifolds in Dimension d > 2 are Scale-Free.” The research paper is freely available online.

“We hope that by applying our understanding of complex networks to one of the fundamental questions in physics we might be able to help explain how discrete quantum spaces emerge,” said author Ginestra Bianconi.

First ever “photo” of light as particle and a wave

Posted by in categories: particle physics, quantum physics

One of the most confounding implications of quantum physics is that light can behave as both a particle (photon) and a wave, depending on the nature of the observation. This is called wave-particle duality, and it has been extremely difficult to picture, let alone observe in both stages simultaneously. Now, physicists publishing in Nature Communications report that they have been able to capture a photograph of wave/particle duality ‘in action’, so to speak. This TED video explains the nature of the effect:

You’re not irrational, you’re just quantum probabilistic: Researchers explain human decision-making with physics theory

Posted by in categories: neuroscience, quantum physics

The next time someone accuses you of making an irrational decision, just explain that you’re obeying the laws of quantum physics.

A new trend taking shape in not only uses to explain humans’ (sometimes) paradoxical thinking, but may also help researchers resolve certain contradictions among the results of previous psychological studies.

According to Zheng Joyce Wang and others who try to model our decision-making processes mathematically, the equations and axioms that most closely match human behavior may be ones that are rooted in quantum physics.

Extending Galactic Habitable Zone Modeling to Include the Emergence of Intelligent Life — By Morrison Ian S. and Gowanlock Michael G. | Astrobiology

Previous studies of the galactic habitable zone have been concerned with identifying those regions of the Galaxy that may favor the emergence of complex life. A planet is deemed habitable if it meets a set of assumed criteria for supporting the emergence of such complex life. In this work, we extend the assessment of habitability to consider the potential for life to further evolve to the point of intelligence—termed the propensity for the emergence of intelligent life, φI.

Quantum Computing – Artificial Intelligence Is Here

Posted by in categories: computing, quantum physics, robotics/AI

Geordie Rose, Founder of D-Wave (recent clients are Google and NASA) believes that the power of quantum computing is that we can ‘exploit parallel universes’ to solve problems that we have no other means of confirming. Simply put, quantum computers can think exponentially faster and simultaneously such that as they mature they will out pace us. Listen to his talk now!
