Famous physicists have brought to us novel theories that explain the world around us. AI can also do the same if we guide it to do so.
Researchers at the German institute trained an AI model to look into simpler interactions in larger complex systems, much like how physicists do.
The development of a new theory is typically associated with the greats of physics. You might think of Isaac Newton or Albert Einstein, for example. Many Nobel Prizes have already been awarded for new theories.
Researchers at Forschungszentrum Jülich have now programmed an artificial intelligence that has also mastered this feat. Their AI is able to recognize patterns in complex data sets and to formulate them in a physical theory. The findings are published in the journal Physical Review X.
In the following interview, Prof. Moritz Helias from Forschungszentrum Jülich’s Institute for Advanced Simulation (IAS-6) explains what the “Physics of AI” is all about and to what extent it differs from conventional approaches.
Two astrophysicists from the Laboratory for Space Research (LSR) at the University of Hong Kong (HKU) have finally solved a 20-year-old astrophysical puzzle concerning the lower-than-expected amounts of the element sulfur found in planetary nebulae (PNe) in comparison to expectations and measurements of other elements and other types of astrophysical objects.
The expected levels of sulfur have long appeared to be “missing in action.” However, they have now finally reported for duty after hiding in plain sight, as a result of leveraging highly accurate and reliable data. The team has recently reported their findings in The Astrophysical Journal Letters.
PNe are the short-lived glowing, ejected, gaseous shrouds of dying stars that have long fascinated and enthused professional and amateur astronomers alike with their colorful and varied shapes. PNe live for only a few tens of thousands of years compared to their host stars, which can take billions of years before they pass through the PN phase on the way to becoming white dwarfs.
New LISA satellite trio will be able to detect the forgotten ‘middle children’ of the black hole family.
More deathism from Mr Tyson. Really I’m a big fan but I dislike this sort of thinking. I commented on the vid.
What if we could live forever? Neil deGrasse Tyson takes us through life and death: if we could live forever what would life really mean? We explore why fresh flowers have meaning and why dogs make every day count. Learn about the Cretaceous-Tertiary Event, The Permian-Triassic Extinction, The Holocene Epoc, and how Earth is one killing machine.
The recent move to open access, in which researchers pay a fee to publish an article in a journal, has also encouraged some publishers to boost revenues by publishing as many papers as possible. At the same time, there has been a rise in retractions, especially of fabricated or manipulated manuscripts sold by “paper mills”. Last year, for example, more than 10 000 journal articles were retracted – a record high – with about 8,000 alone from journals owned by Hindawi, a London-based subsidiary of the publicly-owned publisher Wiley.
The new “purpose-led” coalition is designed to show how the three learned-society publishers have a business model that is not like that of profit-focussed corporations. In particular, they plough all the money generated from publishing back into science by supporting initiatives such as educational training, mentorship, awards and grants. “Purpose-led publishing is about our dedication to science, and to the scientific community,” says Antonia Seymour, IOP Publishing’s chief executive. “We’re proudly declaring that science is our only shareholder.”
Astronomers have long sought to understand the early universe, and thanks to the James Webb Space Telescope (JWST), a critical piece of the puzzle has emerged. The telescope’s infrared detecting “eyes” have spotted an array of small, red dots, identified as some of the earliest galaxies formed in the universe.
This surprising discovery is not just a visual marvel, it’s a clue that could unlock the secrets of how galaxies and their enigmatic black holes began their cosmic journey.
“The astonishing discovery from James Webb is that not only does the universe have these very compact and infrared bright objects, but they’re probably regions where huge black holes already exist,” explains JILA Fellow and University of Colorado Boulder astrophysics professor Mitch Begelman. “That was thought to be impossible.”
This brain-teaser has baffled physicists since 1883. Thanks to some innovative engineering, it finally makes sense.
Physicists finds evidence from just after the Big Bang that supports the controversial holographic universe theory.
The idea of time crystals sparked much controversy and skepticism among physicists, who doubted such a phenomenon could ever be observed.
These ‘photonic time crystals’ can amplify microwave frequencies, but the team that developed them is confident they could work on longer wavelengths too.
