Ivan Smirnov, Leading Research Fellow of the Laboratory of Computational Social Sciences at the Institute of Education of HSE University, has created a computer model that can distinguish high academic achievers from lower ones based on their social media posts. The prediction model uses a mathematical textual analysis that registers users’ vocabulary (its range and the semantic fields from which concepts are taken), characters and symbols, post length, and word length.

Every word has its own rating (a kind of IQ). Scientific and cultural topics, English words, and words and posts that are longer in length rank highly and serve as indicators of good academic performance. An abundance of emojis, words or whole phrases written in capital letters, and vocabulary related to horoscopes, driving, and military service indicate lower grades in school. At the same time, posts can be quite short—even tweets are quite informative. The study was supported by a grant from the Russian Science Foundation (RSF), and an article detailing the study’s results was published in EPJ Data Science.

Foreign studies have long shown that users’ social media behavior—their posts, comments, likes, profile features, user pics, and photos—can be used to paint a comprehensive portrait of them. A person’s social media behavior can be analyzed to determine their lifestyle, personal qualities, individual characteristics, and even their mental health status. It is also very easy to determine a person’s socio-demographic characteristics, including their age, gender, race, and income. This is where profile pictures, Twitter hashtags, and Facebook posts come in.

A pair of statisticians at the University of Waterloo has proposed a math process idea that might allow for teaching AI systems without the need for a large dataset. Ilia Sucholutsky and Matthias Schonlau have written a paper describing their idea and published it on the arXiv preprint server.

Artificial intelligence (AI) applications have been the subject of much research lately, with the development of , researchers in a wide range of fields began finding uses for it, including creating deepfake videos, board game applications and medical diagnostics.

Deep learning networks require large datasets in order to detect patterns revealing how to perform a given task, such as picking a certain face out of a crowd. In this new effort, the researchers wondered if there might be a way to reduce the size of the dataset. They noted that children only need to see a couple of pictures of an animal to recognize other examples. Being statisticians, they wondered if there might be a way to use mathematics to solve the problem.

Black holes are perhaps the most mysterious objects in nature. They warp space and time in extreme ways and contain a mathematical impossibility, a singularity – an infinitely hot and dense object within. But if black holes exist and are truly black, how exactly would we ever be able to make an observation?

This morning the Nobel Committee announced that the 2020 Nobel Prize in physics will be awarded to three scientists – Sir Roger Penrose, Reinhard Genzel and Andrea Ghez – who helped discover the answers to such profound questions. Andrea Ghez is only the fourth woman to win the Nobel Prize in physics.

Robert Penrose is a theoretical physicist who works on black holes, and his work has influenced not just me but my entire generation through his series of popular books that are loaded with his exquisite hand-drawn illustrations of deep physical concepts.

A team of researchers affiliated with a host of institutions in Korea and one in Estonia has found a way to use math to study paintings to learn more about the evolution of art history in the western world. In their paper published in Proceedings of the National Academy of Sciences, the group describes how they scanned thousands of paintings and then used mathematical algorithms to find commonalities between them over time.

Beauty, as the saying goes, is in the eye of the beholder—and so it is also with art. Two people looking at the same can walk away with vastly different impressions. But art also serves, the researchers contend, as a barometer for visualizing the emotional tone of a given society. This suggests that the study of art history can serve as a channel of sorts—illuminating societal trends over time. The researchers further note that to date, most studies of art history have been qualitatively based, which has led to interpretive results. To overcome such bias, the researchers with this new effort looked to mathematics to see if it might be useful in uncovering features of paintings that have been overlooked by human scholars.

The work involved digitally scanning 14,912 paintings—all of which (except for two) were painted by Western artists. The data for each of the paintings was then sent through a mathematical that drew partitions on the based on contrasting colors. The researchers ran the algorithm on each painting multiple times, each time creating more partitions. As an example, the first run of the algorithm might have simply created two partitions on a painting—everything on land, and everything in the sky. The second might have split the land into buildings in one partition and farmland in another.

Have you ever been in more than one place at the same time? If you’re much bigger than an atom, the answer will be no.

But atoms and particles are governed by the rules of quantum mechanics, in which several different possible situations can coexist at once.

Quantum systems are ruled by what’s called a “”: a mathematical object that describes the probabilities of these different possible situations.

The ‘Universal law of touch’ theory was created by researchers at the University of Birmingham, who used mathematical modelling of touch receptors in humans and other animal species. By applying the mathematics of earthquakes to model how vibrations travel through the skin, the team discovered that vibration receptors beneath the skin respond to Rayleigh waves in the same way regardless of age, gender, or even species.

Breakthrough appears to support Elon Musk’s claim we are living in a simulation.

DALLAS, Sept. 29, 2020 /PRNewswire/ — The National Math and Science Initiative has named veteran fundraiser Laure O’Neal as its first chief development officer, charging her and a restructured fundraising team with diversifying the organization’s funding sources.

NMSI was founded in 2007 with generous support from the ExxonMobil Foundation, Texas Instruments Foundation and other corporate and philanthropic organizations. It continues to receive financial support from those and other organizations and is expanding its fundraising to more quickly reach additional students, teachers and school systems across the country.

“Laure brings two decades of experience in connecting corporate, foundation and individual givers with academic institutions and other organizations that support individuals and communities,” said NMSI CEO Bernard A. Harris, Jr. “I’m excited about the energy and expertise Laure brings to secure new support to reach more communities with our programs.”

No one has yet managed to travel through time – at least to our knowledge – but the question of whether or not such a feat would be theoretically possible continues to fascinate scientists.

As movies such as The Terminator, Donnie Darko, Back to the Future and many others show, moving around in time creates a lot of problems for the fundamental rules of the Universe: if you go back in time and stop your parents from meeting, for instance, how can you possibly exist in order to go back in time in the first place?

It’s a monumental head-scratcher known as the ‘grandfather paradox’, but now a physics student Germain Tobar, from the University of Queensland in Australia, says he has worked out how to “square the numbers” to make time travel viable without the paradoxes.

Since we live in a world which isn’t random, but organized at every level, a role for consciousness seems unavoidable. The ‘digital theologian’ shows us compelling evidence from quantum mechanics, mathematics and computer sciences, which not only aligns with a philosophical worldview of the Primacy of Consciousness, but which also assigns a role to information as its modus operandi.

It is quantum mechanics which appears to connect the Universe as a whole to consciousness. A whole, which is more than the sum of its parts and irreducible to mere assumptions deriving from the anatomizing dissection into mental confabulations. Drawing from the holographic principle, perceptroniums and noocentrism, Alex provides crucial keys to unlock the mystery of consciousness to show us how our local consciousness can arise from a non-local cosmic consciousness network.

Carefully building his fortress of arguments, Alex gathers his building bricks from various areas of scientific exploration, ranging from the role of language and tools in the development of our consciousness, the physics of time and epigenetics. Traditional Darwinism and reductive materialism become so challenged, that we become bound to agree with Terence McKenna’s statement that “object fetishism is completely bankrupt.” All these threads are then skillfully woven into the irresistible attractor and only logical conclusion, or Digital Pantheism and Omega Point Cosmology. And with this thus synthesized Apotheosis, Vikoulov brings the architecture of his chef-d’oeuvre to full fruition.
