Free Will and Determinism from a Physicist’s Perspective (Sabine Hossenfelder)

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

The michael shermer show # 294

What is time? Does the past still exist? How did the universe begin and how will it end? Do particles think? Was the universe made for us? Why doesn’t anyone ever get younger? Has physics ruled out free will? Will we ever have a theory of everything? According to Sabine Hossenfelder, it is not a coincidence that quantum entanglement and vacuum energy have become the go-to explanations of alternative healers, or that people believe their deceased grandmother is still alive because of quantum mechanics. Science and religion have the same roots, and they still tackle some of the same questions: Where do we come from? Where do we go to? How much can we know? The area of science that is closest to answering these questions is physics. Over the last century, physicists have learned a lot about which spiritual ideas are still compatible with the laws of nature. Not always, though, have they stayed on the scientific side of the debate.

Exploring the Inner Workings of Human Cells — Database of 200,000 Cell Images Yields New Mathematical Framework

Posted by in categories: biotech/medical, genetics, health, mathematics

Working with hundreds of thousands of high-resolution images, researchers from the Allen Institute for Cell Science, a division of the Allen Institute, put numbers on the internal organization of human cells — a biological concept that has proven incredibly difficult to quantify until now.

The scientists also documented the diverse cell shapes of genetically identical cells grown under similar conditions in their work. Their findings were recently published in the journal Nature.

“The way cells are organized tells us something about their behavior and identity,” said Susanne Rafelski, Ph.D., Deputy Director of the Allen Institute for Cell Science, who led the study along with Senior Scientist Matheus Viana, Ph.D. “What’s been missing from the field, as we all try to understand how cells change in health and disease, is a rigorous way to deal with this kind of organization. We haven’t yet tapped into that information.”

Neil Turok: Physics is in Crisis

Posted by in categories: alien life, information science, mathematics, quantum physics

Renowned physicist Neil Turok, Holder of the Higgs Chair of Theoretical Physics at the University of Edinburgh, joins me to discuss the state of science and the universe. is Physics in trouble? What hope is there to return to more productive and Simple theories? What is Peter Higgs up to?

Neil Turok has been director emeritus of the Perimeter Institute for Theoretical Physics since 2019. He specializes in mathematical physics and early-universe physics, including the cosmological constant and a cyclic model for the universe.

A precise X-ray thermometer for warm dense matter

Posted by in categories: biotech/medical, mathematics

Warm dense matter (WDM) measures thousands of degrees in temperature and is under the pressure of thousands of Earth’s atmospheres. Found in many places throughout the universe, it is expected to have beneficial applications on Earth. However, its investigation is a challenge.

Even the temperature of a material under WDM conditions is anything but easy to determine. A team of researchers led by Dr. Tobias Dornheim from the Center for Advanced Systems Understanding (CASUS) at HZDR has demonstrated a mathematical solution that allows an accurate assessment of the temperature.

As the team points out in the journal Nature Communications, their method can readily be used at experimental facilities of matter research around the world and expedite the gain of scientific knowledge.

The first lab-created ‘quantum abacus’

Posted by in categories: mathematics, quantum physics

Do you want to know whether a very large integer is a prime number or not? Or if it is a “lucky number”? A new study by SISSA, carried out in collaboration with the University of Trieste and the University of Saint Andrews, suggests an innovative method that could help answer such questions through physics, using some sort of “quantum abacus.”

By combining theoretical and , scientists were able to reproduce a quantum potential with corresponding to the first 15 and the first 10 lucky numbers using holographic laser techniques. This result, published in PNAS Nexus, opens the door to obtaining potentials with finite sequences of integers as arbitrary quantum energies, and to addressing mathematical questions related to with quantum mechanical experiments.

“Every physical system is characterized by a certain set of energy levels, which basically make up its ID,” explains Giuseppe Mussardo, at SISSA—International School for Advanced Studies. “In this work, we have reversed this line of reasoning: is it possible—starting from an arithmetic sequence, for example that of prime numbers—to obtain a quantum system with those very numbers as energy levels?”
