Interdependent superconducting networks

Posted by in categories: economics, energy, internet, physics

In 2010 Prof. Shlomo Havlin and collaborators published an article in the journal Nature proposing that the abrupt electricity failure causing the famous 2003 Italy blackout was a consequence of the inter-dependency of two networks. According to Havlin’s theory the dependency between the power network and its communication system led to cascading failures and abrupt collapse. Havlin’s seminal work ignited a new field in statistical physics known as “network of networks” or “interdependent networks” and paved the way for understanding and predicting the effects of the interaction between networks.

The main novelty of Havlin’s model is the existence of two types of links that represent two qualitatively different kinds of interactions. Within networks, links between nodes describe connectivity such as or communication connections. Between networks, on the other hand, links describe dependency relationships in which the functionality of a node in one network depends on the functionality of a node in the other. The communication hubs need electricity and the electric power stations depend on communication control. This dependency leads to a cascading effect in which failure of a single node in one of the networks could lead to an abrupt breakdown of both networks.

Over the past decade or so since, Havlin, from the Department of Physics at Bar-Ilan University in Israel, and others have applied this concept to a variety of abstract systems, such as the internet, road traffic, the economy, infrastructure, and more. But being a theorist, Havlin was unable to manifest the hypothesis on real experimental physical systems and thus the theory couldn’t be confirmed in controlled experiments, nor could it be implemented for device-type applications.

Astronomers spot a rogue supermassive black hole hurtling through space leaving star formation in its wake

Posted by in categories: cosmology, physics

I either think this has to do with some unknown physics problem like lack of some sorta gravity on spacetime fabric or it could be piloted by lifeforms as a black hole spaceship. Either way this could be addressed with a laser that could evaporate it back into light for instance a matter into light laser or put it back in place with a stasis field.


Supermassive black holes (SMBHs) lurk in the center of large galaxies like ours. From their commanding position in the galaxy’s heart, they feed on gas, dust, stars, and anything else that strays too close, growing more massive as time passes. But in rare circumstances, an SMBH can be forced out of its position and hurtle through space as a rogue SMBH.

In a new paper, researchers from Canada, Australia, and the U.S. present evidence of a rogue SMBH that’s tearing through space and interacting with the circumgalactic medium (CGM.) Along the way, the giant is creating and triggering .

Using nanopore single-molecule sensing to identify glycans

Posted by in categories: chemistry, physics

Glycans perform varied and crucial functions in numerous cellular activities. The diverse roles of glycans are matched by their highly complex structures, which derive from differences in composition, branching, regio-and stereochemistry, and modification. This incomparable structural diversity is challenging to the structural analysis of glycans.

Recently, a joint research group led by Prof. Qing Guangyan and Prof. Liang Xinmiao from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) has developed a identification method based on single-molecule sensing through a glycan derivatization strategy. The study was published in Nature Communications on March 28.

Identifying and sequencing glycans using nanopore single-molecule techniques has sparked interest; however, it has achieved little progress over the past dozen years. Only a handful of cases that focused on either high molecular weight polysaccharides or some monosaccharides were reported.

Experiment demonstrates continuously operating optical fiber made of thin air

Posted by in categories: computing, engineering, physics

Great, until the mention of “directed energy”…


Researchers at the University of Maryland (UMD) have demonstrated a continuously operating optical fiber made of thin air.

The most common optical fibers are strands of glass that tightly confine light over long distances. However, these fibers are not well-suited for guiding extremely high-power beams due to glass damage and scattering of laser energy out of the fiber. Additionally, the need for a physical support structure means that glass fiber must be laid down long in advance of light signal transmission or collection.

From Theory to Reality: A Groundbreaking Manifestation of Interdependent Networks in a Physics Lab

Posted by in categories: materials, physics

New findings enable experimental studies to control and further develop the multiscale phenomena of complex interdependent materials.

Bar-Ilan University researchers Havlin and Frydman have demonstrated the “network of networks” theory using a controlled system of interdependent superconducting networks. The study confirms that coupled networks exhibit abrupt transitions under varying temperatures, validating Havlin’s 2010 theory. This groundbreaking research has significant implications across physics, materials science, and device applications, potentially leading to new developments in self-healing systems, sensitive sensors, and network metamaterials.

Metamaterials are engineered materials that have properties not usually found in nature.

Godel & Einstein | Einstein walked with Gödel | Kurt Gödel | Incompleteness theorem | Logic

Posted by in categories: mathematics, physics

This video is about the story of two geniuses, Albert Einstein and the famous logician Kurt Godel. It is about their meeting at IAS, Princeton, New Jersey, when they both walked and discussed many things. For Godel, Einstein was his best friend and till his last days, he remain close to Einstein. Their nature was opposite to each other, yet both of them were very good friends. What did they talk about with each other? What did they share? What were their thoughts? For Godel, Einstein was more like his guide and for Einstein, it was a great pleasure to walk with him.

In the first episode, we discover their first meeting with each other and the development of friendship between them.
