Indian research team develops fully indigenous gallium nitride power switch

Posted by in categories: computing, engineering, military, mobile phones, space, sustainability

Researchers at the Indian Institute of Science (IISc) have developed a fully indigenous gallium nitride (GaN) power switch that can have potential applications in systems like power converters for electric vehicles and laptops, as well as in wireless communications. The entire process of building the switch—from material growth to device fabrication to packaging—was developed in-house at the Center for Nano Science and Engineering (CeNSE), IISc.

Due to their and efficiency, GaN transistors are poised to replace traditional silicon-based transistors as the in many , such as ultrafast chargers for , phones and laptops, as well as space and military applications such as radar.

“It is a very promising and disruptive technology,” says Digbijoy Nath, Associate Professor at CeNSE and corresponding author of the study published in Microelectronic Engineering. “But the material and devices are heavily import-restricted … We don’t have gallium nitride wafer production capability at commercial scale in India yet.” The know-how of manufacturing these devices is also a heavily-guarded secret with few studies published on the details of the processes involved, he adds.

An Introduction to the Problems of AI Consciousness

Posted by in category: robotics/AI

Once considered a forbidden topic in the AI community, discussions around the concept of AI consciousness are now taking center stage, marking a significant shift since the current AI resurgence began over a decade ago. For example, last year, Brad Lemoine, an engineer at Google, made headlines claiming the large language model he was developing had become sentient [1]. CEOs of tech companies are now openly asked in media interviews whether they think their AI systems will ever become conscious [2,3].

Unfortunately, missing from much of the public discussion is a clear understanding of prior work on consciousness. In particular, in media interviews, engineers, AI researchers, and tech executives often implicitly define consciousness in different ways and do not have a clear sense of the philosophical difficulties surrounding consciousness or their relevance for the AI consciousness debate. Others have a hard time understanding why the possibility of AI consciousness is at all interesting relative to other problems, like the AI alignment issue.

This brief introduction is aimed at those working within the AI community who are interested in AI consciousness, but may not know much about the philosophical and scientific work behind consciousness generally or the topic of AI consciousness in particular. The aim here is to highlight key definitions and ideas from philosophy and science relevant for the debates on AI consciousness in a concise way with minimal jargon.

11 Best Biological Age Tests for 2024

Posted by in categories: biological, life extension

Do you use biological age tests to quantify your fitness goals? I updated this piece with the latest products (there are a ton) and found a few discount codes too.

Update 10/2/2023: This post has been updated since we originally published it. I evaluated additional top biological age tests for 2024, removed companies that are no longer offering tests, and updated the post to reflect the most recent pricing. The post has been cleaned up and links were made current.

According to TikTok, I’m either 46-years-old, 37-years-old, or 29-years-old. As a 34-year-old woman, that’s, ahem, less than ideal.

Beyond Combustion: Highly Efficient Quantum Engines on the Horizon

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

Scientists unveil exciting possibilities for the development of highly efficient quantum devices.

Quantum mechanics is a branch of physics that explores the properties and interactions of particles at very small scale, such as atoms and molecules. This has led to the development of new technologies that are more powerful and efficient compared to their conventional counterparts, causing breakthroughs in areas such as computing, communication, and energy.

A quantum leap in engine design.

Pythagorean Theorem Found On Clay Tablet 1,000 Years Older Than Pythagoras

Posted by in categories: education, information science, mathematics

Study math for long enough and you will likely have cursed Pythagoras’s name, or said “praise be to Pythagoras” if you’re a bit of a fan of triangles.

But while Pythagoras was an important historical figure in the development of mathematics, he did not figure out the equation most associated with him (a2 + b2 = c2). In fact, there is an ancient Babylonian tablet (by the catchy name of IM 67118) which uses the Pythagorean theorem to solve the length of a diagonal inside a rectangle. The tablet, likely used for teaching, dates from 1770 BCE – centuries before Pythagoras was born in around 570 BCE.

Another tablet from around 1800–1600 BCE has a square with labeled triangles inside. Translating the markings from base 60 – the counting system used by ancient Babylonians – showed that these ancient mathematicians were aware of the Pythagorean theorem (not called that, of course) as well as other advanced mathematical concepts.

Researchers advance effort to turn diamonds into a quantum simulator

Posted by in category: quantum physics

Diamonds are often prized for their flawless shine, but Chong Zu, an assistant professor of physics in Arts & Sciences at Washington University in St. Louis, sees a deeper value in these natural crystals. As reported in Physical Review Letters, Zu and his team have taken a major step forward in a quest to turn diamonds into a quantum simulator.

Co-authors of the paper include Kater Murch, the Charles M. Hohenberg Professor of Physics, and Ph.D. students Guanghui He, Ruotian (Reginald) Gong and Zhongyuan Liu. Their work is supported in part by the Center for Quantum Leaps, a signature initiative of the Arts & Sciences that aims to apply quantum insights and technologies to physics, biomedical and , drug discovery and other far-reaching fields.

The researchers transformed by bombarding them with . Some of those nitrogen atoms dislodge carbon atoms, creating flaws in an otherwise perfect crystal. The resulting gaps are filled with electrons that have their own spin and magnetism, that can be measured and manipulated for a wide range of applications.
