When I design physical objects, I think in boxes and simple, usually circular-section curves. This has been true when I freehand build physical objects, as well as when I model things on the computer. Fillets are about as crazy as I get.
I'm in awe of artists whose design imaginations extend to "organic" shapes.
Reminds me of music a bit. I was a reasonably good high school musician. Played multiple instruments; did fine in music competition on several of them. That's just en…

Tiny engine runs hotter than the sun to probe the frontiers of thermodynamics
Scientists have created the world's hottest engine running at temperatures hotter than those reached in the sun's core. The team from King's College London and collaborators believe their platform could provide an unparalleled understanding of the laws of thermodynamics on a small scale, and provide the foundation for a new, efficient way to compute how proteins fold—the subject of last year's Nobel Prize in Chemistry.

Radiolunadiff: Estimation of wireless network signal strength in lunar terrain
In this paper, we propose a novel physics-informed deep learning architecture for predicting radio maps over lunar terrain. Our approach integrates a physics-based lunar terrain generator, which produces realistic topography informed by publicly available NASA data, with a ray-tracing engine to create a high-fidelity dataset of radio propagation scenarios. Building on this dataset, we introduce a triplet-UNet architecture, consisting of two standard UNets and a diffusion network, to model compl…
