Artificial intelligence and the evolution of the fractal economy

Posted by in categories: biotech/medical, economics, finance, particle physics, robotics/AI

Money makes the world go round, or so they say. Payments, investments, insurance and billions of transactions are the beating heart of a fractal economy, which echoes the messy complexity of natural systems, such as the growth of living organisms and the bouncing of atoms.

Financial systems are larger than the sum of their parts. The underlying rules that govern them might seem simple, but what surfaces is dynamic, chaotic and somehow self-organizing. And the blood that flows through this fractal heartbeat is data.

Today, 2.5 exabytes of data are being produced daily. That number is expected to grow to 44 zettabytes a day by 2020 (Source: GigaOm). This data, along with interconnectivity, correlation, predictive analytics and machine learning, provides the foundation for our AI-powered future.

New blow for ‘supersymmetry’ physics theory

Posted by in categories: futurism, particle physics

In a new blow for the futuristic “supersymmetry” theory of the universe’s basic anatomy, experts reported fresh evidence Monday of subatomic activity consistent with the mainstream Standard Model of particle physics.

New data from ultra high-speed proton collisions at Europe’s Large Hadron Collider (LHC) showed an exotic particle dubbed the “beauty quark” behaves as predicted by the Standard Model, said a paper in the journal Nature Physics.

Previous attempts at measuring the beauty quark’s rare transformation into a so-called “up quark” had yielded conflicting results. That prompted scientists to propose an explanation beyond the Standard Model—possibly supersymmetry.

Majorana Particles Observed for 1st Time: Contain Their Own Antiparticles –“Impacts Future of Quantum Computers”

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

Around 75 years ago, Italian physicist Ettore Majorana hypothesized the existence of exotic particles that are their own antiparticles. Since then, interest in these particles, known as Majorana fermions, has grown enormously given that they could play a role in creating a quantum computer. Majoranas have already been described very well in theory. However, examining them and obtaining experimental evidence is difficult because they have to occur in pairs but are then usually bound to form one normal electron. Ingenious combinations and arrangements of various materials are therefore required to generate two Majoranas and keep them apart.

The Missing Universe: CERN Has Started Searching for “Dark Photons”

Posted by in categories: cosmology, particle physics

In Brief

  • Dark matter seems to outweigh visible matter roughly six to one, making up about 27% of the universe.
  • Physicists from CERN now believe there’s a fifth universal force that rules the behavior of dark matter, and is transmitted by a particle called the dark photon.

Nano-materials start-up uses graphene to sweeten loudspeaker response

Posted by in categories: nanotechnology, particle physics, quantum physics

Want a louder bass or speakers in general get Quantum.


Ora, a Montreal-based tech start-up, has announced that it has developed the first consumer-ready graphene loudspeaker.

The company believes that graphene holds the ideal properties sought after in loudspeaker diaphragms: stiffness (graphene is stronger than diamond) and lightness (graphene is the thinnest known material, one atom thick).

A new ring to slow down antimatter

Posted by in category: particle physics

You could mistake ELENA for a miniature accelerator. But, unlike most accelerators, it’s housed in a hangar and you can take it all in in just a single glance. The biggest difference though, is that it doesn’t accelerate particles, but decelerates them.

CERN’s brand-new machine measures just 30 metres in circumference and has just begun its first tests with beam.

The ELENA (Extra Low ENergy Antiproton) deceleration ring will be connected to the Antiproton Decelerator (AD), which has been in service since 2000. The AD is a unique facility that enables the study of antimatter.

NASA’s EMDrive And The Quantum Theory Of Pilot Waves

Posted by in categories: particle physics, quantum physics, space travel

There has been a lot of digital ink spilled over the recent paper on the reactionless thrust device known as the EMDrive. While it’s clear that a working EM Drive would violate well established scientific theories, what isn’t clear is how such a violation might be resolved. Some have argued that the thrust could be an effect of Unruh radiation, but the authors of the new paper argue instead for a variation on quantum theory known as the pilot wave model.

One of the central features of quantum theory is its counter-intuitive behavior often called particle-wave duality. Depending on the situation, quantum objects can have characteristics of a wave or characteristics of a particle. This is due to the inherent limitations on what we can know about quanta. In the usual Copenhagen interpretation of quantum theory, an object is defined by its wavefunction. The wavefunction describes the probability of finding a particle in a particular location. The object is in an indefinite, probabilistic state described by the wavefunction until it is observed. When it is observed, the wavefunction collapses, and the object becomes a definite particle with a definite location.

While the Copenhagen interpretation is not the best way to visualize quantum objects it captures the basic idea that quanta are local, but can be in an indefinite state. This differs from the classical objects (such as Newtonian theory) where things are both local and definite. We can know, for example, where a baseball is and what it is doing at any given time.
