Differential equations are fundamental tools in physics: they are used to describe phenomena ranging from fluid dynamics to general relativity. But when these equations become stiff (i.e. they involve ...

Modeling how cars deform in a crash, how spacecraft respond to extreme environments, or how bridges resist stress could be made thousands of times faster thanks to new artificial intelligence that ...

Two new approaches allow deep neural networks to solve entire families of partial differential equations, making it easier to model complicated systems and to do so orders of magnitude faster. In high ...

How many times does the letter “r” appear in the word “strawberry”? According to formidable AI products like GPT-4o and Claude, the answer is twice. Large language models (LLMs) can write essays and ...

How do we make decisions about a situation we have not encountered before? New work from the Center for Mind and Brain at the University of California, Davis, shows that we can solve abstract problems ...

This study investigated students' modeling progress and strategies in a problem-solving simulation game through content analysis, and through supervised and unsupervised lag sequential analysis (LSA).

A Dec. 5 Instagram post (direct link, archive link) shows a TikTok in which a man reads and shows screenshots from various NASA reports that reference a "flat, non-rotating earth" model. "NASA ...
