Scientists Finally Solve the 40-Year-Old Mystery of Strange Metals
Posted by Arthur Brown in categories: computing, quantum physics
For nearly 40 years, materials called ‘strange metals’ have flummoxed quantum physicists, defying explanation by operating outside the normal rules of electricity.
Now research led by Aavishkar Patel of the Flatiron Institute’s Center for Computational Quantum Physics (CCQ) in New York City has identified, at long last, a mechanism that explains the characteristic properties of strange metals.
In the August 18 issue of Science, Patel and his colleagues present their universal theory of why strange metals are so weird—a solution to one of the greatest unsolved problems in condensed matter physics.

Physicists confirm existence of “demon” particle
Posted by Paul Battista in category: particle physics
A “demon” particle that has been haunting physicists for nearly 70 years has been found in an experiment by American researchers.
It is not a particle in the traditional sense like a proton or electron. It is a “composite” particle made up of a combination of electrons, in a solid.
In 1956, theoretical physicist David Pines predicted that electrons in a solid could do something strange. Electrons have both mass and charge. But Pines asserted that combinations of electrons in a solid could form a composite particle that is massless, has no charge and does not interact with light.

Solving ordinary and partial differential equations using an analog computing system based on ultrasonic metasurfaces
Posted by Paul Battista in categories: information science, supercomputing
Wave-based analog computing has recently emerged as a promising computing paradigm due to its potential for high computational efficiency and minimal crosstalk. Although low-frequency acoustic analog computing systems exist, their bulky size makes it difficult to integrate them into chips that are compatible with complementary metal-oxide semiconductors (CMOS). This research paper addresses this issue by introducing a compact analog computing system (ACS) that leverages the interactions between ultrasonic waves and metasurfaces to solve ordinary and partial differential equations. The results of our wave propagation simulations, conducted using MATLAB, demonstrate the high accuracy of the ACS in solving such differential equations. Our proposed device has the potential to enhance the prospects of wave-based analog computing systems as the supercomputers of tomorrow.

How Long Should You Live? Star Trek, Dr. Emanuel, & The Ethics of Life Extension
Posted by Montie Adkins in categories: biotech/medical, ethics, life extension
I will try to live as long as possible.
Dr. Ezekiel Emanuel plans to reject life-extending medical care at the age of 75. The reason he does this is quite similar to why the Kaelons commit ritual suicide in Star Trek: The Next Generation. Does this make sense?
