The Illusion of Understanding: MIT Unmasks the Myth of AI’s Formal Specifications

Posted by in categories: mathematics, robotics/AI

Some researchers see formal specifications as a way for autonomous systems to “explain themselves” to humans. But a new study finds that we aren’t understanding.

As autonomous systems and artificial intelligence become increasingly common in daily life, new methods are emerging to help humans check that these systems are behaving as expected. One method, called formal specifications, uses mathematical formulas that can be translated into natural-language expressions. Some researchers claim that this method can be used to spell out decisions an AI will make in a way that is interpretable to humans.

Psychiatric patients almost twice as likely to have multiple physical ailments – new study.

A new study, conducted by Anglia Ruskin University (ARU) in collaboration with the University of Cambridge’s Biomedical Research Centre, has revealed significant findings about the physical health of psychiatric patients. This extensive analysis incorporated data from 19 different studies, involving 194,123 psychiatric patients globally, and compared them to 7,660,590 individuals in control groups.

Unlocking the secrets of spin with high-harmonic probes

Posted by in categories: computing, quantum physics

Deep within every piece of magnetic material, electrons dance to the invisible tune of quantum mechanics. Their spins, akin to tiny atomic tops, dictate the magnetic behavior of the material they inhabit. This microscopic ballet is the cornerstone of magnetic phenomena, and it’s these spins that a team of JILA researchers—headed by JILA Fellows and University of Colorado Boulder professors Margaret Murnane and Henry Kapteyn—has learned to control with remarkable precision, potentially redefining the future of electronics and data storage.

In a Science Advances publication, the JILA team—along with collaborators from universities in Sweden, Greece, and Germany—probed the spin dynamics within a special material known as a Heusler compound: a mixture of metals that behaves like a single magnetic material.

For this study, the researchers utilized a compound of cobalt, manganese, and gallium, which behaved as a conductor for electrons whose spins were aligned upwards and as an insulator for electrons whose spins were aligned downwards.

What exposure to radiation does to glass on the moon over billions of years

Posted by in categories: materials, space

A team of materials scientists at Songshan Lake Materials Laboratory, working with colleagues from the China Academy of Space Technology and the Chinese Academy of Sciences, all in China, has found that billions of years of exposure to radiation has made glass on the moon harder.

In their paper published in the journal Science Advances, the group describes how they tested samples of lunar regolith brought to Earth by China’s Chang’e-5 lunar lander and then treated the samples to rejuvenate them for comparison purposes.

Humans have been making glass for approximately 4,000 years; nature, on the other hand, has been doing it for billions of years. In this new effort, the research team studied glass that has been made naturally on the moon by meteoroids striking, and melting —some of it billions of years old.

A twist on atomic sheets to create new materials

Posted by in categories: particle physics, quantum physics

The way light interacts with naturally occurring materials is well-understood in physics and materials science. But in recent decades, researchers have fabricated metamaterials that interact with light in new ways that go beyond the physical limits imposed on naturally occurring materials.

A metamaterial is composed of arrays of “meta-atoms,” which have been fabricated into desirable structures on the scale of about a hundred nanometers. The structure of arrays of meta-atoms facilitate precise light-matter interactions. However, the large size of meta-atoms relative to regular atoms, which are smaller than a nanometer, has limited the performance of metamaterials for practical applications.

Now, a collaborative research team led by Bo Zhen of the University of Pennsylvania has unveiled a new approach that directly engineers atomic structures of material by stacking the two-dimensional arrays in spiral formations to tap into novel light-matter interaction. This approach enables metamaterials to overcome the current technical limitations and paves the way for next-generation lasers, imaging, and quantum technologies. Their findings were published in the journal Nature Photonics.

The B-21 Raider, the Air Force’s new nuclear stealth bomber, takes flight for first time

Posted by in categories: materials, military

The B-21 Raider took its first test flight on Friday, moving the futuristic warplane closer to becoming the nation’s next nuclear weapons stealth bomber.

The Raider flew in Palmdale, California, where it has been under testing and development by Northrop Grumman.

The Air Force is planning to build 100 of the warplanes, which have a flying wing shape much like their predecessor the B-2 Spirit but will incorporate advanced materials, propulsion and stealth technology to make them more survivable in a future conflict. The plane is planned to be produced in variants with and without pilots.
