Plotnitsky’s New Perspective On Schrödinger’s Cat Experiment Challenges Quantum Understanding

Posted by in category: quantum physics

I found this on NewsBreak.


The Schrödinger’s Cat Experiment, a paradox illustrating the concept of superposition in quantum mechanics, has been reinterpreted by Purdue University’s Professor Arkady Plotnitsky. His perspective, based on “reality without realism” (RWR) interpretations, suggests that the reality behind quantum phenomena is beyond conception. This view repositions classical physics as part of fundamental physics, a role typically reserved for quantum physics and relativity. This new interpretation challenges traditional understanding of the experiment and suggests our comprehension of reality is insufficient to fully grasp quantum phenomena. This perspective opens new research avenues in quantum physics and emphasizes the importance of philosophical considerations in physics study.

The Schrödinger’s Cat Experiment is a thought experiment proposed by physicist Erwin Schrödinger. It is a paradox that illustrates the concept of superposition in quantum mechanics. The experiment involves a cat that is placed in a sealed box with a radioactive source and a poison that will be released when the radioactive source decays. According to quantum mechanics, the cat is both alive and dead until the box is opened and the cat’s state is observed.

Unlocking the Quantum Code: International Team Cracks a Long-Standing Physics Problem

Posted by in categories: computing, quantum physics

“In quantum many-body theory, we are often faced with the situation that we can perform calculations using a simple approximate interaction, but realistic high-fidelity interactions cause severe computational problems,” says Dean Lee, Professor of Physics from the Facility for Rare Istope Beams and Department of Physics and Astronomy (FRIB) at Michigan State University and head of the Department of Theoretical Nuclear Sciences.

Practical Applications and Future Prospects

Wavefunction matching solves this problem by removing the short-distance part of the high-fidelity interaction and replacing it with the short-distance part of an easily calculable interaction. This transformation is done in a way that preserves all the important properties of the original realistic interaction. Since the new wavefunctions are similar to those of the easily computable interaction, the researchers can now perform calculations with the easily computable interaction and apply a standard procedure for handling small corrections – called perturbation theory.

Solar storms that caused pretty auroras can create havoc with technology—here’s how

Posted by in category: futurism

At the weekend, millions of people around the world were treated to a mesmerizing display of the aurora borealis and aurora australis, better known as the northern and southern lights. The lights, usually seen in crown-like regions surrounding the Earth’s poles, were pushed to mid-latitudes by heightened activity from the sun.

NASA’s Mars Sample Return Mission is in trouble—but it’s a Vital Step to Sending Humans to the Red Planet

Posted by in categories: drones, space

NASA recently asked the scientific community to help come up with innovative ideas for ways to carry out its Mars Sample Return (MSR) mission. This was in response to a report by an independent board that deemed that its US$11 billion (£8.7 billion) price tag was too expensive and its 2040 timeline too far in the future.

In brief, the ambitious plan was to collect rock samples cached inside containers by NASA’s Perseverance rover and deliver them to laboratories on Earth. Perseverance has been exploring Mars’ Jezero Crater, thought to have once hosted an ancient lake, since 2021. The mission would deliver the samples by sending a lander that carries a rocket (NASA’s Sample Retrieval Lander) down to the surface of Mars.

Perseverance would then deliver the cached rock samples to the lander, with small drone helicopters delivered on the lander as a back up. Perseverance’s samples would then be launched into Mars’ orbit using the lander’s rocket. A spacecraft already in Martian orbit, the Earth Return Orbiter, would then intercept these samples and deliver them to Earth.

Clogged Arteries Worsened by Cells that Behave like Cancer Cells

Posted by in category: biotech/medical

Columbia University researchers have found cells inside clogged arteries share similarities with cancer and aggravate atherosclerosis, raising the possibility that anticancer drugs could be used to treat atherosclerosis and prevent heart attacks.

Their study found that smooth muscle cells that normally line the inside of our arteries migrate into atherosclerotic plaques, change their cell identity, activate cancer genes, and proliferate inside the plaques.

“Our study shows that these transformed muscle cells are driving atherosclerosis, opening the door to new ways to treat the disease, potentially with existing cancer drugs,” says Muredach Reilly, MD, the Florence and Herbert Irving Endowed Professor of Medicine at Columbia University Vagelos College of Physicians and Surgeons and director of Columbia’s Irving Institute for Clinical and Translational Research.

Physicist Studying SARS-CoV-2 Virus Believes He Has Found Hints We Are Living In A Simulation

Dr. Melvin Vopson’s study delves into the intriguing concept of information entropy, which differs from traditional physical entropy. Physical entropy measures the disorder within a system’s physical states, whereas information entropy pertains to the arrangement and complexity of information within those states.

Vopson applied this principle to the SARS-CoV-2 virus, analyzing its mutations through an information entropy lens. He explained, “The physical entropy of a given system is a measure of all its possible physical microstates compatible with the macrostate…the additional entropy associated with them is called the entropy of information.”
