Meta’s AI luminary LeCun explores deep learning’s energy frontier

Posted by in categories: physics, robotics/AI

So-called energy-based models, which borrow concepts from statistical physics, may lead the way to ‘abstract prediction,’ says Yann LeCun, allowing for a ‘unified world model’ for AI capable of planning.

Physicists: We Are On The Verge Of Discovering Fifth Dimension And It Will Change Everything We Know About Physics

Posted by in categories: physics, space

What a time to be alive… We are on the verge of discovering the fifth dimension and it will change everything we know about the Universe.


Scientists are sometimes questioned if they conduct fresh experiments in the lab or continue to repeat previous ones for which they have certain outcomes. While most scientists undertake the former, scientific advancement also relies on conducting the latter and validating whether what we think we know remains true in light of fresh knowledge.

Printing circuits on rare nanomagnets puts a new spin on computing

Posted by in categories: information science, nanotechnology, physics, robotics/AI

New research artificially creating a rare form of matter known as spin glass could spark a new paradigm in artificial intelligence by allowing algorithms to be directly printed as physical hardware. The unusual properties of spin glass enable a form of AI that can recognize objects from partial images much like the brain does and show promise for low-power computing, among other intriguing capabilities.

“Our work accomplished the first experimental realization of an artificial spin glass consisting of nanomagnets arranged to replicate a neural network,” said Michael Saccone, a post-doctoral researcher in at Los Alamos National Laboratory and lead author of the new paper in Nature Physics. “Our paper lays the groundwork we need to use these practically.”

Spin glasses are a way to think about material structure mathematically. Being free, for the first time, to tweak the interaction within these systems using electron-beam lithography makes it possible to represent a variety of computing problems in spin-glass networks, Saccone said.

Italian scientists hacked pizza physics to make dough without yeast

Posted by in categories: chemistry, cybercrime/malcode, food, physics

Ernesto Di Maio is severely allergic to the yeast in leavened foods. “I have to go somewhere and hide because I will be fully covered with bumps and bubbles on the whole body,” he says. “It’s really brutal.”

Di Maio is a materials scientist at the University of Naples Federico II where he studies the formation of bubbles in polymers like polyurethane. He’s had to swear off bread and pizza, which can make outings in Italy a touch awkward. “It’s quite hard in Naples not to eat pizza,” he explains. “People would say, ‘Don’t you like pizza? Why are you having pasta? That’s strange.’”

So Di Maio put Iaccarino and another graduate student, Pietro Avallone, to work on a project to make pizza dough without yeast. The results of this scientific and culinary experiment are published in Tuesday’s edition of Physics of Fluids. Di Maio pulled in another colleague: chemical engineer Rossana Pasquino who studies the flow of materials, everything from toothpaste to ketchup to plastics. “Pizza [dough] is a funny material,” she explains, “because it flows, but it has to be also like rubber. It has to be elastic enough [when it’s cooked] to be perfect when you eat it.” — I had to post this because I love Pizza.

Black holes found to exert a pressure on their environment

Posted by in categories: cosmology, physics

Physicists at the University of Sussex have discovered that black holes exert a pressure on their environment, in a scientific first.

In 1974 Stephen Hawking made the seminal discovery that emit thermal radiation. Previous to that, black holes were believed to be inert, the final stages of a dying heavy star.

The University of Sussex scientists have shown that they are in fact even more complex thermodynamic systems, with not only a temperature but also a .

Star’s Mysterious Orbit Around Black Hole Proves Einstein Was Right— Again

Posted by in categories: cosmology, physics

Star’s mysterious orbit around black hole proves einstein was right all along—again.


The star, known as S2, has a 16-year elliptical orbit. It came near 20 billion kilometers of our black hole, Sagittarius A*, last year. If Isaac Newton’s traditional definition of gravity is correct, S2 should then continue on its previous orbit’s course through space. But it didn’t work.

Elon Musk Thinks Destinus Technology Will Soon End The War Against Russia, Know How

Posted by in categories: business, drones, Elon Musk, physics, robotics/AI, space travel

Mikhail Kokorich is the founder of Destinus. This serial entrepreneur has been dubbed Russia’s Elon Musk by his public relations team. The Russian businessman says his business, Destinus, is developing a hydrogen-powered, zero-emissions transcontinental delivery drone that can travel at speeds up to Mach 15.

Destinus plans to combine the technological advancements from a spaceplane with the ordinary and straightforward physics from a glider to create a hyperplane that will meet the many demands of a hyper-connected world.
