Maple seeds’ unique spinning motion allows them to travel far even in the rain, a new study shows
When wind or other disturbances detach winged maple seeds called samaras from their parent tree, they spin through the air – and can even spin when it’s raining. Impacts by high-speed raindrops only briefly interrupt the seed’s spinning because the seed can shed the drop rapidly and restart its spinning in less time than it takes to...
The science behind airplane deicing – a mechanical engineer explains how chemistry and physics make flying a more uplifting experience
If you are a frequent flyer, you’ve probably been at the airport waiting to jet somewhere on a winter trip when the voice of an airline employee announces over the intercom that there will be a slight delay while the plane gets deiced. But how does this process actually work, and why is it needed?
As a mechanical engineer[1] who...
AIs flunk language test that takes grammar out of the equation
Generative AI systems like large language models and text-to-image generators can pass rigorous exams that are required of anyone seeking to become a doctor[1] or a lawyer[2]. They can perform better than most people in Mathematical Olympiads[3]. They can write halfway decent poetry[4], generate aesthetically pleasing paintings[5] and compose...
