Could a hidden variable explain the weirdness of quantum physics?

Weirdness of quantum entanglement is explained by hidden variables? If so, we have never found them.

Seqenenre Tao, the pharaoh who died in battle

Posted by in category: energy

Seqenenre Tao was the pharaoh who ruled southern Egypt in the late 17th dynasty, roughly between 1,558 and 1,553 BC.

That was a troubled time. The Hyksos (whose name in ancient Egyptian was Heqau-khasut, “the rulers of foreign lands”) occupied the northern part of Egypt and took Avaris (present-day Tell el Dabaa) as their capital during a time called the “second intermediate period” (1650−1550 BC).

Although the pharaohs maintained power over the south (with capital in Thebes), the entire territory was forced to pay tribute to the invaders.

Is Brain Learning Weaker Than Artificial Intelligence?

Posted by in category: robotics/AI

Summary: Artificial neural networks based on human brain dynamics can outperform current deep learning models in learning capabilities.

Source: Bar-Ilan University.

Traditionally, artificial intelligence stems from human brain dynamics. However, brain learning is restricted in a number of significant aspects compared to deep learning (DL).

New map of the universe’s matter reveals a possible hole in our understanding of the cosmos

Posted by in categories: cosmology, internet, mapping

Scientists have made one of the most precise maps of the universe’s matter, and it shows that something may be missing in our best model of the cosmos.

Created by pooling data from two telescopes that observe different types of light, the new map revealed that the universe is less “clumpy” than previous models predicted — a potential sign that the vast cosmic web that connects galaxies is less understood than scientists thought.

According to our current understanding, the cosmic web is a gigantic network of crisscrossing celestial superhighways paved with hydrogen gas and dark matter. Taking shape in the chaotic aftermath of the Big Bang, the web’s tendrils formed as clumps from the roiling broth of the young universe; where multiple strands of the web intersected, galaxies eventually formed. But the new map, published Jan. 31 as three separate studies in the journal Physical Review D, shows that in many parts of the universe, matter is less clumped together and more evenly spread out than theory predicts it should be.

Ultrafast water permeation through nanochannels with a densely fluorous interior surface

Posted by in categories: innovation, sustainability

The key innovation in this new desalination technology is fluorine, a hydrophobic element that that’s long been prized for its desire to be left alone. It’s no accident that fluorine is a key ingredient in Teflon, which is used on non-stick pans to keep fried eggs from sticking and inside pipes to make fluids flow more efficiently. At the nanoscopic level, fluorine repels negatively charged ions, including the chlorine in salt (NaCl). Its electric properties also break down clumps of water molecules that can keep the liquid from flowing as freely as possible. -(IE)

-Desalination is something people need to consider with rising sea levels and changing weather patterns, like drought.


Oligoamide nanoring-based fluorous nanochannels in bilayer membranes enable ultrafast water permeation and desalination.

Google is asking employees to test potential ChatGPT competitors, including a chatbot called ‘Apprentice Bard’

Posted by in categories: futurism, robotics/AI

Google is testing new artificial intelligence-powered chat products that are likely to influence a future public product launch. They include a new chatbot and a potential way to integrate it into a search engine.

The Alphabet company is working on a project under its cloud unit called “Atlas,” which is a “code red” effort to respond to ChatGPT, the large language chatbot that took the public by storm when it launched late last year.
