Description On the beach in the Netherlands in 2016. Oddly shaped rings. Is this the same effect we’re seeing? Here, a lot of different effects are at play. Credit: Simen Andreas Ådnøy Ellingsen, NTNU Researcher proves that boat wakes can be skewed. He solved a 127-year-old physics problem on paper and proved that off-centered boat wakes could exist. Five years later, practical experiments proved him right. “Seeing the pictures appear on the computer screen was the best day at work I’ve ever had,” says Simen Ådnøy Ellingsen, an associate professor at the Norwegian University of Science and Technology’s (NTNU) Department of Energy and Process Engineering. That was the day that PhD candidate Benjamin Keeler Smeltzer and master’s student Eirik Æsøy had shown in the lab that Ellingsen was right and sent him the photos from the experiment. Five years ago, Ellingsen had challenged accepted knowledge from 1887, armed with a pen and paper, and won. He solved a problem regarding the so-called Kelvin angle in boat wakes, which has been unchallenged for 127 years. The boat wake is the v-shaped pattern that a boat or canoe makes when moving through the water. You’ve undoubtedly seen one at some point.

Description QUANTUM mechanics is often called a theory of the very small. In reality, it explains phenomena on a vast range of scales – from elementary particles and their interactions, through atoms and molecules, all the way to neutron stars and the supernovae that spawn them. So far, essentially all its predictions have been confirmed by experiments. It is the most successful theory of material reality we have ever had. So why have so many physicists, from Albert Einstein onwards, taken the view that quantum theory is wrong? The reasons lie in its mysterious nature, in the phenomena it doesn’t explain and the answers it doesn’t give. That is reason enough to seek what might lie beyond it. I believe we already have the outline of what this deeper answer looks like. We are only at the start of this work, but by digging down into the fundamental principles that underlie reality, and weeding out what is right and what is wrong about our current ideas, we can see glimpses of a truly unifying picture of physics. It comes at a price: to go beyond quantum, we must totally upend long-held ideas of how the universe hangs together. It is easy to state the basic problem of quantum mechanics as a theory of reality: it doesn’t tell us what is happening in reality. It has two different laws to describe how things and events evolve. The first applies most of the time, and describes quantum objects as wave-like entities embodied in a mathematical construction known as a wave function. These objects … Read more: https://www.newscientist.com/article/mg24332440-600-quantum-weirdness-isnt-real-weve-just-got-space-and-time-all-wrong/#ixzz5xJQwwwTy

Description Quantum teleportation has made a leap up in complexity. Physicists have teleported more information at once than has ever been possible before, paving the way for a global quantum internet that would be extraordinarily secure from hacking. This is not teleportation as you might imagine it from science fiction. Rather than transporting matter through space, it involves moving information about the quantum state of a particle. So far, scientists have only been able to teleport quantum bits, or qubits, the simplest unit of quantum information in which a particle can be in … Read more: https://www.newscientist.com/article/2214135-quantum-teleportation-used-to-send-3d-information-for-the-first-time/#ixzz5xJBSyx84
