A type of mathematical problem that was previously impossible to solve can now be successfully analysed with artificial intelligence An AI system developed by Meta can find solutions to maths problems that have eluded mathematicians for over a century, researchers at the firm claim. The problems involve mathematical tools called Lyapunov functions, named after mathematician Aleksandr Lyapunov, which analyse whether a system will remain stable over time, meaning its behaviour can be predicted. One famous example of such a system is the motion of three celestial bodies as a result of their mutual gravitational interactions – describing the behaviour of this “three-body problem” is extremely challenging.
Spear-throwing tools called atlatls allow humans to launch projectiles over great distances, but Neanderthals apparently never used them – and an experiment involving a 9-metre-tall platform may explain why An ancient spear-throwing tool enabled prehistoric hunters to boost the distance they could launch a feathered projectile – but the unexpected negative effects of gravity on the tool may explain why it was never adopted by Neanderthals and some Homo sapiens groups. The spear-throwing tool – which is known as an atlatl – is a handheld stick with a groove at the end for holding a projectile. It acts as a lever to amplify the projectile-flinging momentum that can be achieved by the human arm.
Time for a round of laughs with the finalists for the 2024 Comedy Wildlife Awards . The shortlist announced Wednesday are “a cracking collection of amazing, jaw dropping and laugh out loud photos of some of the most incredible wildlife that we share this planet with” officials said in a statement. Shortlisted images and videos from the 2024 edition include a cheetah playing hide-and-seek behind a tree, bears hugging it out, a fish chasing an eagle across the sky and a tiny flying squirrel "bossing it like a Mafia Boss!" The free competition is open to all wildlife photography novices, amateurs and professionals and celebrates the hilarity of our natural world. "This shortlist of entries shows some of the most spectacular photos ever entered, catching wildlife’s funniest moments on camera," the competition said in their statement.This year’s final shortlist of 40 standalone photographs, three videos and four portfolio entries were chosen from thousands of ent...
