Collective Evolution

Thursday, July 24th, 2014

Introducing Collective Evolution, which inspires us to begin expanding our way of thinking so we can take conscious steps towards creating BIG change on the planet.

What is Collective Evolution All About?

Collective Evolution (CE) creates content that engages us all to begin thinking consciously about what it means to be a human on the planet and encourage us to live in harmonious ways. This might mean living sustainably, eating and being healthy, creating a relationship with self and creating a better world together. We care about balance in our world and lives which means looking at all areas of how we function. We cover alternative news, health, science and a very neutral non new agey type of spirituality.

A grassroots organization started in 2009, CE is now one of the worlds most popular alternative media, production company and community outlets that gives others an opportunity to expand their everyday way of thinking. CE’s content ranges from writing to video to live events all with one common goal: to raise awareness towards how our world truly functions and encourages conscious change that moves beyond it.

Who is Collective Evolution?

All CE content is brought into conscious existence by an awesome, (but not too awesome) dynamic (but not too dynamic) community of writers, filmmakers, editors, speakers and other phenomenally creative minds… but not too phenomenal.

The world’s first photonic router

Friday, July 18th, 2014

Weizmann Institute scientists have demonstrated the first photonic router — a quantum device based on a single atom that enables routing of single photons, a step toward overcoming the difficulties in building quantum computers.

A photonic switch

At the core of the device is an atom that can switch between two states. The state is set just by sending a single particle of light — or photon — from the right or the left via an optical fiber.

The atom, in response, then reflects or transmits the next incoming photon, accordingly. For example, in one state, a photon coming from the right continues on its path to the left, whereas a photon coming from the left is reflected backwards, causing the atomic state to flip.

In this reversed state, the atom lets photons coming from the left continue in the same direction, while any photon coming from the right is reflected backwards, flipping the atomic state back again. This atom-based switch is solely operated by single photons — no additional external fields are required.

“In a sense, the device acts as the photonic equivalent of electronic transistors, which switch electric currents in response to other electric currents,” says Dr. Barak Dayan, head of the Weizmann Institute’s Quantum Optics group. The photons are both the units comprising the flow of information and the ones that control the device.

This achievement was made possible by the combination of two state-of-the-art technologies.

One is laser cooling and trapping of atoms. The other is the fabrication of chip-based, ultra-high quality miniature optical resonators that couple directly to the optical fibers.

Dayan’s lab at the Weizmann Institute is one of a handful worldwide that has mastered both these technologies.

The main motivation behind the effort to develop quantum computers is the quantum phenomenon of superposition, in which particles can exist in many states at once, potentially being able to process huge amounts of data in parallel. Yet superposition can only last as long as nothing observes or measures the system otherwise it collapses to a single state.

Unlike atoms, photons are the most promising candidates for communication between quantum systems because they do not interact with each other at all, and interact very weakly with other particles.

    President Obama creating task force to save bee population from collapse

    Tuesday, July 15th, 2014

    The Obama administration is taking steps to save bees from extinction. In a memorandum released on Friday, the White House is seeking to create a new task force to investigate the effects of new insecticides on bees and other crucial pollinators. The group will have 180 days to produce a strategy to curb the rapid die-off scientists have observed in the last decade.

    The memorandum directs the Environmental Protection Agency (EPA) to research how neonicotinoids, a special class of insecticide, is linked to bee colony collapse. The USDA has already reported that 31 percent of commercial US bee colonies died off or disappeared in 2012, and the trend has continued since then, causing alarm among food producers who depend on bees to pollinate their crops. While the decline has so far been linked to disease and the destruction of habitats, a recent Harvard study did indicate that exposure to two kinds of neonicotinoids caused bees to leave their hives and die.

    THE LATEST EFFORT TO SAVE THE DWINDLING BEE POPULATION

    The creation of this task force is only the latest effort to save the dwindling bee population. The European Union has already banned the use of neonicotinoids for two years as a means of curtailing the die-off. Meanwhile, researchers in Australia earlier this year sought to strap sensors on 5,000 bees as a novel means of tracking the insects’ movements and how their react to their changing environment.

    Of Particular Significance Site

    Wednesday, July 9th, 2014

    A great resource in particle physics scouted – Of Particular Significance, Conversations About Science with Theoretical Physicist Matt Strassler – http://www.profmattstrassler.com

    From About page:

    The long-term goal of the site is to provide the public with both the background information needed to understand more about science in general — what it is, how it is done, what it means to modern life — and more specifically about what is happening to their investment in my field — particle physics. Meanwhile, I will also be providing some up-to-date information about what is happening in particle physics and other nearby subjects.

    Since this site is still young, there are still many web-pages still to be constructed, and I will be adding things regularly. So when you visit the site, in addition to looking at any daily posts to the blog, please check also for new pedagogical or analytic articles that will be linked within the site. Those articles will remain up until they go out of date, and so my intention is that they be carefully written and pedagogically oriented.

    Have We Been Interpreting Quantum Mechanics Wrong This Whole Time?

    Tuesday, July 1st, 2014

    For nearly a century, “reality” has been a murky concept. The laws of quantum physics seem to suggest that particles spend much of their time in a ghostly state, lacking even basic properties such as a definite location and instead existing everywhere and nowhere at once. Only when a particle is measured does it suddenly materialize, appearing to pick its position as if by a roll of the dice.

    PrintOriginal story reprinted with permission from Quanta Magazine, an editorially independent division of SimonsFoundation.org whose mission is to enhance public understanding of science by covering research developments and trends in mathematics and the physical and life sciences.
    This idea that nature is inherently probabilistic — that particles have no hard properties, only likelihoods, until they are observed — is directly implied by the standard equations of quantum mechanics. But now a set of surprising experiments with fluids has revived old skepticism about that worldview. The bizarre results are fueling interest in an almost forgotten version of quantum mechanics, one that never gave up the idea of a single, concrete reality.

    The experiments involve an oil droplet that bounces along the surface of a liquid. The droplet gently sloshes the liquid with every bounce. At the same time, ripples from past bounces affect its course. The droplet’s interaction with its own ripples, which form what’s known as a pilot wave, causes it to exhibit behaviors previously thought to be peculiar to elementary particles — including behaviors seen as evidence that these particles are spread through space like waves, without any specific location, until they are measured.

    Particles at the quantum scale seem to do things that human-scale objects do not do. They can tunnel through barriers, spontaneously arise or annihilate, and occupy discrete energy levels. This new body of research reveals that oil droplets, when guided by pilot waves, also exhibit these quantum-like features.

    To some researchers, the experiments suggest that quantum objects are as definite as droplets, and that they too are guided by pilot waves — in this case, fluid-like undulations in space and time. These arguments have injected new life into a deterministic (as opposed to probabilistic) theory of the microscopic world first proposed, and rejected, at the birth of quantum mechanics.

    “This is a classical system that exhibits behavior that people previously thought was exclusive to the quantum realm, and we can say why,” said John Bush, a professor of applied mathematics at the Massachusetts Institute of Technology who has led several recent bouncing-droplet experiments. “The more things we understand and can provide a physical rationale for, the more difficult it will be to defend the ‘quantum mechanics is magic’ perspective.”

    Magical Measurements

    The orthodox view of quantum mechanics, known as the “Copenhagen interpretation” after the home city of Danish physicist Niels Bohr, one of its architects, holds that particles play out all possible realities simultaneously. Each particle is represented by a “probability wave” weighting these various possibilities, and the wave collapses to a definite state only when the particle is measured. The equations of quantum mechanics do not address how a particle’s properties solidify at the moment of measurement, or how, at such moments, reality picks which form to take. But the calculations work. As Seth Lloyd, a quantum physicist at MIT, put it, “Quantum mechanics is just counterintuitive and we just have to suck it up.”
