| Medium | GrooveSquid.com (original content) | Medium Difficulty Summary Large Language Models (LLMs) have become valuable tools for scientific discovery due to their vast knowledge and advanced reasoning capabilities. However, they struggle to effectively simulate observational feedback and ground it with language, hindering advancements in physical scientific discovery. In contrast, human scientists formulate hypotheses, conduct experiments, and revise theories through observational analysis. Inspired by this process, we propose enhancing LLMs’ knowledge-driven abstract reasoning abilities with the computational strength of simulations. Our Scientific Generative Agent (SGA) framework combines LLMs as knowledgeable thinkers proposing scientific hypotheses and reason about discrete components like physics equations or molecule structures, while simulations serve as experimental platforms providing observational feedback and optimizing via differentiability for continuous parts like physical parameters. We demonstrate SGA’s efficacy in constitutive law discovery and molecular design, revealing novel solutions that differ from conventional human expectations yet remain coherent upon analysis. |
| Low | GrooveSquid.com (original content) | Low Difficulty Summary Imagine using super-powerful computers to help us make new scientific discoveries! These powerful machines are called Large Language Models. They can learn a lot and think really well. But sometimes they get stuck because they don’t know how to use real-world data, like what we see with our eyes or in experiments. Humans do science by making guesses, doing tests, and adjusting their ideas based on what they observe. So, we wanted to help these powerful computers be better at science too! We created a new tool called Scientific Generative Agent (SGA) that lets LLMs think about scientific problems and then use simulations to test their ideas. This helps them come up with new solutions that are actually possible. We tested SGA on some tough problems like figuring out how materials work together and designing new molecules, and it did really well! |
