‎The Joy of Why: Will AI Ever Have Common Sense? on Apple Podcasts

Posted by in categories: robotics/AI, transportation

How do you teach ChatGPT common sense? Train it on questions that adults would never think to ask. In this week’s “The Joy of Why,” computer scientist Yejin Choi talks with co-host Steven Strogatz about how training AI can mimic the “why-this, why-that” curiosity of a toddler.

High-speed rail project linking two major U.S. cities takes step forward: ‘A historic milestone’

Posted by in category: transportation

The California High-Speed Rail Authority just received environmental approval to connect downtown Los Angeles to the Bay Area with a bullet train capable of reaching speeds of up to 200 miles per hour, KTLA5 reported.

KTLA5 called the approval “a historic milestone in a state notorious for holding up construction projects for environmental review.”

Metamaterials for the data highway: New concept offers potential for more efficient data storage

Posted by in categories: computing, transportation

Researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), TU Chemnitz, TU Dresden and Forschungszentrum Jülich have been the first to demonstrate that not just individual bits, but entire bit sequences can be stored in cylindrical domains: tiny, cylindrical areas measuring just around 100 nanometers.

World’s fastest brick-laying construction robot lands on American shores

Posted by in categories: robotics/AI, transportation

A robotic truck equipped with a 105-ft (32-m) telescopic boom arm has just journeyed from Australia to Florida. Now the construction robot will get busy churning out up to 10 houses in a bid to become the employee of choice for building entire communities.

The truck and its accompanying brick-laying arm is known as the Hadrian X and has been developed by robotics company FBR, which first announced its prototype in 2015. That machine could complete a full-sized house in two days. Last year, FBR (which used to stand for Fastbrick Robotics), showed off the new Hadrian X which, at top speed, could stack 500 USA-format masonry blocks per hour.

Researchers Create New Class of Materials called ‘Glassy Gels’

Posted by in categories: chemistry, engineering, transportation

Researchers have created a new class of materials called “glassy gels” that are very hard and difficult to break despite containing more than 50% liquid. Coupled with the fact that glassy gels are simple to produce, the material holds promise for a variety of applications.

Gels and glassy polymers are classes of materials that have historically been viewed as distinct from one another. Glassy polymers are hard, stiff and often brittle. They’re used to make things like water bottles or airplane windows. Gels – such as contact lenses – contain liquid and are soft and stretchy.

“We’ve created a class of materials that we’ve termed glassy gels, which are as hard as glassy polymers, but – if you apply enough force – can stretch up to five times their original length, rather than breaking,” says Michael Dickey, corresponding author of a paper on the work and the Camille and Henry Dreyfus Professor of Chemical and Biomolecular Engineering at North Carolina State University. “What’s more, once the material has been stretched, you can get it to return to its original shape by applying heat. In addition, the surface of the glassy gels is highly adhesive, which is unusual for hard materials.”

The nuclear magnetic resonance in bismuth metal powder has been observed from 9 to 19 Mc/sec at 4.2\ifmmode^\circ\else\textdegree\fi{}K. The isotropic and anisotropic Knight shifts and the quadrupole coupling constant have been determined as (−1.25\ifmmode\pm\else\textpm\fi{}.30)%, (−0.3\ifmmode\pm\else\textpm\fi{}0.3)%, and 2.10\ifmmode\pm\else\textpm\fi{}.05 Mc/sec, respectively. The intrinsic linewidth was found to be 130\ifmmode\pm\else\textpm\fi{}20 kc/sec. A technique is developed to take into consideration the broadening of the observed lines due to the combined effects of the magnetic dipolar broadening and the width due to the quadrupolar splitting of each line.

Breakthrough hypersonic dual-mode ramjet offers 3x increase in airflow

Posted by in categories: innovation, transportation

A Cincinnati-based aerospace company has successfully represented a new, cutting-edge hypersonic dual-mode ramjet. The engine could enable high-speed flight and longer range across numerous multi-mission aircraft.

GE Aerospace took 11 months to develop the ramjet, which could increase in airflow compared to previously flight-tested hypersonic technology demonstrators.

“The rapid progression from design to testing underscores our commitment to driving innovation in hypersonic technologies,” said Amy Gowder, president and CEO of Defense & Systems at GE Aerospace.

Tesla CEO Elon Musk reiterates single FSD stack update for V12.5.x

Posted by in categories: Elon Musk, transportation

Musk seemed to acknowledge the issue, though he also hinted at upcoming improvements to FSD’s highway performance. “12.5.x will finally combine the city and highway software stacks,” Musk wrote.

This is not the first time that Elon Musk mentioned a single FSD stack for both inner city and highway driving. Back in May, Musk estimated that FSD V12.5 should be out in late June, and the update should see some notable improvements.

Tesla Robotaxi unveiling event pushed back from August: report

Posted by in categories: Elon Musk, robotics/AI, transportation

CEO Elon Musk teased it in April for the first time, and it was set to bring unprecedented momentum to the company’s years of development of Full Self-Driving and fully autonomous driving technologies.

However, Tesla is not quite ready to roll out the Robotaxi prototypes.

First reported by Bloomberg, Tesla is said to need more time to build the first units of the Robotaxi. Because it is built upon the automaker’s next-generation platform, which is to blame for the company’s lack of growth in 2024, more development is needed.
