An AI-powered method has led to the discovery of new families of unstable "singularities" across three different fluid equations, marking a significant advance in the study of fluid dynamics. This breakthrough, involving Google DeepMind in collaboration with researchers from Brown University, New York University, and Stanford University, suggests a previously invisible underlying structure to these complex equations.
Derya Unutmaz, MD, highlighted the significance of the finding, stating: > "We used a new AI-powered method to discover new families of unstable 'singularities' across three different fluid equations. A clear and unexpected pattern emerged: as the solutions become more unstable, one of the key properties falls very close to a straight line. This suggests a new, underlying structure to these equations that was previously invisible." This observation indicates a fundamental mathematical regularity in chaotic fluid behavior.
The research leverages Physics-Informed Neural Networks (PINNs), a machine learning technique trained to adhere to physical laws rather than relying solely on vast datasets. This approach allowed for unprecedented accuracy, with errors equivalent to predicting the Earth's diameter within a few centimeters, enabling the identification of elusive solutions like unstable singularities. The Navier-Stokes equations, which govern fluid motion and are one of the Millennium Prize Problems, have long challenged mathematicians.
This discovery is not merely academic; it holds profound implications for various fields. A Google DeepMind blog post noted that the new method could help mathematicians tackle long-standing challenges in mathematics, physics, and engineering. Potential applications include improving climate models, enhancing weather forecasting, and designing more efficient aircraft, by providing a deeper understanding of phenomena like turbulence and vortex formation.
The collaboration represents a new era of computer-assisted mathematics, where AI acts as a discovery tool, exploring complex mathematical landscapes previously inaccessible to conventional methods. This innovative approach is expected to accelerate scientific discovery and pave the way for computer-assisted proofs in solving other intractable problems in science.
