The first eight Dedekind numbers have been known to us, but the ninth one has remained elusive — until now.

Mathematics is a fascinating subject with many unsolved mysteries, such as the Riemann hypothesis, Fermat’s last theorem, Goldbach’s conjecture, and Dedekind’s numbers. The Dedekind numbers were first discovered in the 19th century by Richard Dedekind and have interested mathematicians ever since.

The first eight Dedekind numbers have been known to us, but the ninth one has remained elusive until now. KU Leuven and Paderborn University scientists have solved a decades-old mathematics problem by computing the ninth Dedekind number.

Simple molecular liquids such as water or glycerol are of great importance for technical applications, in biology or even for understanding properties in the liquid state. Researchers at the Max Planck Institut für Struktur und Dynamik der Materie (MPSD) have now succeeded in observing liquid glycerol in a completely unexpected rubbery state.

In their article published in Proceedings of the National Academy of Sciences, the researchers report how they created rapidly expanding bubbles on the surface of the liquid in vacuum using a pulsed laser. However, the thin, micrometers-thick liquid envelope of the bubble did not behave like a viscous liquid dissipating deformation energy as expected, but like the elastic envelope of a rubber toy balloon, which can store and release elastic energy.

It is the first time an elasticity dominating the flow behavior in a Newtonian liquid like glycerol has been observed. Its existence is difficult to reconcile with common ideas about the interactions in liquid glycerol and motivates the search for more comprehensive descriptions. Surprisingly, the elasticity persists over such long timescales of several microseconds that it could be important for very rapid engineering applications such as micrometer-confined flows under high pressure. Yet, the question remains unsettled whether this behavior is a specific property of liquid glycerol, or rather a phenomenon that occurs in many molecular liquids under similar conditions but has not been observed so far.

A newly created real-life Transformer is capable of reconfiguring its body to achieve eight distinct types of motion and can autonomously assess the environment it faces to choose the most effective combination of motions to maneuver.

The new robot, dubbed M4 (for Multi-Modal Mobility Morphobot) can roll on four wheels, turn its wheels into rotors and fly, stand on two wheels like a meerkat to peer over obstacles, “walk” by using its wheels like feet, use two rotors to help it roll up steep slopes on two wheels, tumble, and more.

AI-powered augmented reality devices will give human beings ‘superpowers’ to detect lies and ‘read’ emotions of people they are talking to, a futurist has claimed.

Speaking exclusively to DailyMail.com, Devin Liddell, Principal Futurist at Teague, said that computer vision systems built into headsets or glasses will pick up emotional cues that un-augmented human eyes and instincts cannot see.

The technology would let people know if their date is lying or is sexually aroused, along with spotting a lying politician.

And so it begins. I’ve seen one job already on glass door that requires knowledge of AI and I only barely started looking. I wasn’t even specifically looking for AI jobs. I’ve seen other articles where ChatGPT can be used to make thousands in side hustles. So far, so good. I’ll have to check out those job hustles and see if I can make use of those articles. Just one job is enough for me. One article claimed some jobs will pay you as much as 800k if you know AI.

Generative artificial intelligence is all the rage now but the AI boom is not just all hype, said Dan Ives from Wedbush Securities, who calls it the “fourth industrial revolution playing out.”

“This is something I call a 1995 moment, parallel with the internet. I do not believe that this is a hype cycle,” the managing director and senior equity research analyst told CNBC’s “Squawk Box Asia” on Wednesday.

Two rival theories about the basis of perception went head-to-head in neuroscience experiments, but advocates of “losing” idea aren’t conceding yet.

A company called Moolec has created transgenic soya beans called “Piggy Sooy” in which a quarter of the protein is pig protein rather than plant protein.

Now consider two tabletops, parallel to each other but not touching. The second tabletop is also infinite in two dimensions, and other kinds of creatures live there. Finally, imagine that a narrow tunnel connects the two spaces somewhere.

Without access to the tunnel, the creatures dwelling in each space believe they live in a single, infinite universe. This is especially true if the tunnel lies outside their cosmic horizon. They will never know that their universes are part of a larger structure, a two-dimensional multiverse. It is easy to imagine an infinite number of two-dimensional flat spaces stacked on top of one another, each connected to the next by a similar tunnel, and each tunnel inaccessible to any of the universes’ inhabitants.

The multiverse need not be so simple, either. Universes can be curved and finite, sprouting from an infinite mother universe. The sprouting universes may themselves be infinite. Think of bubbles being blown from a piece of bubble gum. Little bubbles will shrink back, while bigger ones might keep on growing. If a bubble starts growing in a heavily populated region of flat space, some of the inhabitants will be carried into it. Others will remain outside, horrified to see their friends sucked into oblivion. But most of the creatures in the growing bubble survive their ordeal and start to explore their new world. Generations pass. Their scientists measure the curvature of space and see that their universe is closed, like the surface of a sphere. Since the bubble kept on growing, the tunnel-like aperture to the original universe is well beyond their cosmic horizon. These creatures live in a closed, expanding universe, unaware of their connection to a flat, infinite space. Meanwhile, creatures in the original space saw the aperture to the bubble universe close more and more until it became too narrow to cross. All that is left, to them, is a scar in space marking the long-forgotten birthing event. The bubble universe is isolated from its mother universe.

Developing The Low Earth Orbit Economy On The World’s First Commercial Space Station — David Zuniga, Senior Director, In-Space Solutions, Axiom Space

David Zuniga is Senior Director of In-Space Solutions at Axiom Space (https://www.axiomspace.com/), a space infrastructure developer headquartered in Houston, Texas, which plans human spaceflight for government-funded and commercial astronauts, engaging in in-space research, in-space manufacturing, and space exploration. The company aims to own and operate the world’s first commercial space station, and Mr. Zuniga helps to develop strategy and growth around Axiom’s Low Earth Orbit (LEO) economy, also playing a critical role in business and technical integration of Axiom’s in-space manufacturing and research capabilities for Axiom Station architecture.
