Fluid-solid coupling paper fixes two-phase simulation instabilities

This 2023 ACM TOG paper presents a lattice-Boltzmann two-phase solver that tightly couples moving solids with water-air flow while reducing pressure oscillations, boundary artifacts, and blowups in fast-motion scenes. The authors show more robust behavior across challenging cases like skipping stones and tumbling coins, with reported efficiency gains versus prior methods in at least one benchmark.

// ANALYSIS

The core win here is not flashy architecture, it is numerical robustness that finally makes complex water-air-plus-rigid-body interactions practical at high Reynolds numbers.

–Improves momentum exchange, interfacial force handling, and two-way coupling to stabilize fast or sudden solid motion.
–Uses a phase-field plus velocity-distribution LBM setup with finer phase-grid treatment for cleaner boundary behavior.
–Demonstrates qualitative realism with bubbles, splashes, and thin-object motion, plus comparisons against real footage.
–Reports speed improvements over earlier related work, including about 4.5x faster performance in a propeller scenario.

Plannotator 0.19.24 adds Amp support and configurable storage

Plannotator 0.19.24 is a substantial release that expands the tool beyond Claude Code with native Amp support, adds a `PLANNOTATOR_DATA_DIR` override so users can move the default `~/.plannotator` data directory, introduces Auto Mode in the permission selector for newer Claude Code versions, and fixes a Pi approval crash after plan acceptance. The update folds multiple stacked PRs into one release and pushes the project further toward a multi-agent review layer rather than a single-agent hook utility.

Aaronson says AI turns mathematicians into curators

Scott Aaronson says recent AI results in mathematics, including a GPT-5.5 Pro solution to Erdős’s Unit Distance Problem, suggest humans may increasingly focus on choosing questions and interpreting model outputs. He extends the argument to AI-written fiction and the Vatican’s AI encyclical as signs of a broader cultural shift.
