Project mention: New Proofs Probe the Limits of Mathematical Truth | news.ycombinator.com | 2025-02-04
https://opendata.cern.ch/
I've gotten into 3D printing, and load and temperature data of different filaments is always appreciated.
Mixing materials together, microscopic images, etc...
I get a lot of value from YouTubers who simple follow a consistent methodology of endurance or break testing products or materials. Tear downs and documentation of internals, performance statistics, etc...
Channels like CNCKitchen or ProjectFarm are excellent citizen scientists for example.
