NASA image reveals hidden sunlight that may help solve solar mystery

Posted by in categories: nuclear energy, space

The observation reveals high-energy X-rays that could help solve a mystery regarding the Sun’s corona.

As a new series of NASA observations show, there’s a lot more to sunlight than meets the eye.

This hidden light could help solve a mystery related to our host star’s incredibly hot outer atmosphere, the corona.

Theorizing the Basis of Our World: A Reading List on Quantum Reality

Posted by in categories: mobile phones, nuclear energy, particle physics, quantum physics

Quantum Mechanics is the science behind nuclear energy, smart phones, and particle collisions. Yet, almost a century after its discovery, there is still controversy over what the theory actually means. The problem is that its key element, the quantum-mechanical wave function describing atoms and subatomic particles, isn’t observable. As physics is an experimental science, physicists continue to argue over whether the wave function can be taken as real, or whether it is just a tool to make predictions about what can be measured—typically large, “classical” everyday objects.

The view of the antirealists, advocated by Niels Bohr, Werner Heisenberg, and an overwhelming majority of physicists, has become the orthodox mainstream interpretation. For Bohr especially, reality was like a movie shown without a film or projector creating it: “There is no quantum world,” Bohr reportedly affirmed, suggesting an imaginary border between the realms of microscopic, “unreal” quantum physics and “real,” macroscopic objects—a boundary that has received serious blows by experiments ever since. Albert Einstein was a fierce critic of this airy philosophy, although he didn’t come up with an alternative theory himself.

For many years only a small number of outcasts, including Erwin Schrödinger and Hugh Everett populated the camp of the realists. This renegade view, however, is getting increasingly popular—and of course triggers the question of what this quantum reality really is. This is a question that has occupied me for many years, until I arrived at the conclusion that quantum reality, deep down at the most fundamental level, is an all-encompassing, unified whole: “The One.”

Researchers detail never-before-seen properties in a family of superconducting Kagome metals

Posted by in categories: computing, mobile phones, nuclear energy, quantum physics

Dramatic advances in quantum computing, smartphones that only need to be charged once a month, trains that levitate and move at superfast speeds. Technological leaps like these could revolutionize society, but they remain largely out of reach as long as superconductivity—the flow of electricity without resistance or energy waste—isn’t fully understood.

One of the major limitations for real-world applications of this technology is that the materials that make superconducting possible typically need to be at extremely cold temperatures to reach that level of electrical efficiency. To get around this limit, researchers need to build a clear picture of what different superconducting materials look like at the atomic scale as they transition through different states of matter to become superconductors.

Scholars in a Brown University lab, working with an international team of scientists, have moved a small step closer to cracking this mystery for a recently discovered family of superconducting Kagome metals. In a new study, they used an innovative new strategy combining nuclear magnetic resonance imaging and a quantum modeling theory to describe the microscopic structure of this superconductor at 103 degrees Kelvin, which is equivalent to about 275 degrees below 0 degrees Fahrenheit.

Coming to a campus near you: Nuclear microreactors

Posted by in categories: biotech/medical, military, nuclear energy

If your image of nuclear power is giant, cylindrical concrete cooling towers pouring out steam on a site that takes up hundreds of acres of land, soon there will be an alternative: tiny nuclear reactors that produce only one-hundredth the electricity and can even be delivered on a truck.

Small but meaningful amounts of electricity — nearly enough to run a small campus, a hospital or a military complex, for example — will pulse from a new generation of micronuclear reactors. Now, some universities are taking interest.

“What we see is these advanced reactor technologies having a real future in decarbonizing the energy landscape in the U.S. and around the world,” said Caleb Brooks, a nuclear engineering professor at the University of Illinois at Urbana-Champaign.

World-first ‘super’ magnet sparks nuclear fusion breakthrough

Posted by in categories: innovation, nuclear energy

A UK firm has announced a world-first set of “super” magnets that can be used for testing nuclear fusion power plants.

Tokamak Energy said the Demo4 magnet has a magnetic field strength that is nearly a million times stronger than the Earth’s magnetic field, making it capable of confining and controlling the extremely hot plasma created during the fusion process.

Nuclear fusion has been hailed as the “holy grail” of clean energy, with scientists working on the technology since the 1950s.

Watch nuclear fusion reactor form plasma: “You can’t take your eyes off it”

Posted by in categories: nuclear energy, particle physics, space travel

What does the inside of a nuclear fusion reactor look like?

“It looks like the future,” Stuart White, head of communications at Tokamak Energy, told Newsweek. “A spaceship. It’s extremely striking, powerful and exciting. You can’t take your eyes off it.”

Nuclear fusion is a technology that creates energy in the same way as the sun: it occurs when two atoms are thrust together with such force that they combine into a single, larger atom and release huge amounts of energy in the process.
