AI Has Cracked a Key Mathematical Puzzle for Understanding Our World –“Partial differential equations can describe everything from planetary motion to plate tectonics, but they’re notoriously hard to solve. …[a new deep-learning technique for solving PDEs] is 1,000 times faster than traditional mathematical formulas, which would ease our reliance on supercomputers and increase our computational capacity to model even bigger problems. That’s right. Bring it on,” reports Karen Hao for MIT Technology Review
How many alien civilizations are out there? A new galactic survey holds a clue –The Milky Way is full of habitable real estate, with roughly half of all sunlike stars hosting Earth-size worlds that could be friendly to life, reports National Geographic.
‘It’s not a question of belief’: the film examining government UFO records –“The Phenomenon” studies the history of UFO claims from the 1940s to this summer’s revelation of a Department of Defense investigation into military sightings, reports The Guardian.
First light on a next-gen astronomical survey toward a new understanding of the cosmos –Groundbreaking all-sky survey will bolster our understanding of the formation and evolution of galaxies, reports Carnegie Institution for Science.
Secrets behind ‘Game of Thrones’ unveiled by data science and network theory –Researchers from five universities across the UK and Ireland came together to unravel “A Song of Ice and Fire”, the books on which the TV series is based, reports University of Warwick.
Physicists 3D Print a Boat That Could Sail Down a Human Hair –“Researchers at Leiden University have 3D printed the smallest boat in the world: a 30-micrometer copy of Benchy the tug boat, a well-known 3D printer test object. This boat is so small, it could float down the interior of a human hair. The 3D-printed boat is part of an exploration of microswimmers, microscopic organisms or objects that can move through liquids,” reports John Biggs for Gizmodo.
