The Well: a Large-Scale Collection of Diverse Physics Simulations for Machine Learning
Abstract
Machine learning based surrogate models offer researchers powerful tools for accelerating simulation-based workflows. However, as standard datasets in this space often cover small classes of physical behavior, it can be difficult to evaluate the efficacy of new approaches. To address this gap, we introduce the Well: a large-scale collection of datasets containing numerical simulations of a wide variety of spatiotemporal physical systems. The Well draws from domain experts and numerical software developers to provide 15TB of data across 16 datasets covering diverse domains such as biological systems, fluid dynamics, acoustic scattering, as well as magneto-hydrodynamic simulations of extra-galactic fluids or supernova explosions. These datasets can be used individually or as part of a broader benchmark suite. To facilitate usage of the Well, we provide a unified PyTorch interface for training and evaluating models. We demonstrate the function of this library by introducing example baselines that highlight the new challenges posed by the complex dynamics of the Well. The code and data is available at this URL.
Great Firewall of China Leak

1. Introduction
The Great Firewall of China (GFW) experienced the largest leak of internal documents in its history on Thursday September 11, 2025. Over 500 GB of source code, work logs, and internal communication records were leaked, revealing details of the GFW’s research, development, and operations.
The leak originated from a core technical force behind the GFW: Geedge Networks (whose chief scientist is Fang Binxing) and the MESA Lab at the Institute of Information Engineering, Chinese Academy of Sciences. The documents show that the company not only provides services to governments in places like Xinjiang, Jiangsu, and Fujian, but also exports censorship and surveillance technology to countries such as Myanmar, Pakistan, Ethiopia, Kazakhstan, and other unidentified country under the “Belt and Road” framework.
