The 2020 Nobel Prize in physics awarded for work on black holes. An astrophysicist explains the trailblazing discoveries

Posted by in categories: cosmology, mathematics, physics, singularity

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.

Using math to study paintings to learn more about the evolution of art history

Posted by in categories: evolution, information science, mathematics, media & arts

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.

Could Schrödinger’s cat exist in real life? Our research may soon provide the answer

Posted by in categories: mathematics, particle physics, quantum physics

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.

‘Universal law of touch’ could help make VR indistinguishable from reality

Posted by in categories: Elon Musk, mathematics, virtual reality

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.

National Math and Science Initiative Appoints First Chief Development Officer

Posted by in categories: finance, mathematics, science

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.”

Identical Quantum Particles Pass Practicality Test

A Physicist Has Come Up With Math That Makes ‘Paradox-Free’ Time Travel Plausible

Posted by in categories: mathematics, physics, space, time travel

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.

Theology of Digital Physics: The Universe of Conscious Minds

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.

The strange storms on Jupiter

Posted by in categories: climatology, mathematics, space

At the south pole of Jupiter lurks a striking sight—even for a gas giant planet covered in colorful bands that sports a red spot larger than the earth. Down near the south pole of the planet, mostly hidden from the prying eyes of humans, is a collection of swirling storms arranged in an unusually geometric pattern.

Since they were first spotted by NASA’s Juno space probe in 2019, the storms have presented something of a mystery to scientists. The storms are analogous to hurricanes on Earth. However, on our planet, hurricanes do not gather themselves at the poles and twirl around each other in the shape of a pentagon or hexagon, as do Jupiter’s curious storms.

Now, a research team working in the lab of Andy Ingersoll, Caltech professor of planetary science, has discovered why Jupiter’s storms behave so strangely. They did so using math derived from a proof written by Lord Kelvin, a British mathematical physicist and engineer, nearly 150 years ago.
