From Fold to Function: Origami Robotics Gets One Map
A 2026 arXiv preprint unifies rigid folding, elastic bending and snap-through in one discrete-geometry model for origami robots — and why AEC should care.
Grammar-Bound AI Discovers Material Laws Buildings Can Actually Trust
A new arXiv framework uses grammar-based symbolic regression to discover dissipation potentials guaranteed to obey thermodynamics — for buildings.
Claude Fable 5 Ships Mythos-Class Power Behind a Quiet Fallback Switch
Anthropic's Claude Fable 5 brings day-long codebase migrations to AEC toolchains — but its silent Opus 4.8 fallback and data-retention rule are the real story.
Neural Radiance Fields & 3D Gaussians: Your Building, Fitted Not Modelled
How neural radiance fields and 3D Gaussian Splatting turn a phone walk-around into a metric-accurate building capture — the foundation, the maths, and a Hack.
One sparse factor, three passes: DiffPhD rewires the soft-body solver stack
DiffPhD, a GPU differentiable solver, stays stable at 100x stiffness contrast and runs 10x faster — bringing gradient-based form-finding to the AEC desk.
The cheapest tactile sensor is a camera you already own
EgoTouch infers contact, force and pressure from egocentric video — no tactile hardware at inference. Inside the systems move behind scalable robot touch.
One Hyperbolic Element Decides If Your System Holds Steady
A May 2026 arXiv paper reduces a hard dynamics question to one algebraic test — is there a hyperbolic element? — and shows why the rigid body can't comply.
A Novelist Replaced Adobe with Git. Architects, Draw Your Dependency Graph.
DJ Speckhals replaced Word, InDesign, and Kindle Create with Pandoc, Typst, and Git. Why his dependency graph is a warning for every Autodesk shop.
A zero-knowledge proof that hides its secret in math's blind spot
Rahul Ilango built a noninteractive zero-knowledge proof from Gödel's limits — what trust-without-disclosure means for BIM, tendering, and e-permits.
Michigan's Spring 2026 Floods: A Dependency Graph from Orbit
Grand River crested April 8 just below major flood. NASA Landsat reveals what an aging dam fleet looks like under rain-on-snow stress in 2026.
