Gear-based Metamaterials for Extraordinary Bandgap Tunability
Metamaterials can be engineered with tunable bandgaps to adapt to dynamic and complex environments, particularly for controlling elastic waves and vibration. However, achieving wide-range, seamless, reversible, in-situ and robust tunability remains challenging and often impractical due to limitations in bandgap mechanisms and design principles. Here, we introduce gear-based metamaterials with unprecedented bandgap tunability. Our approach leverages Taiji planetary gear systems as variable-frequ…

I got bored so here's some ideas I had about ways to make non-digital AI models which anyone can try if you're bored enough!
- gear ratios for weights
- pulleys for weights
- probs could get pipe diameter haha
- sunglasses (shine light through and brightest is the result)
And there's one analog one I'm trying myself which I can keep posting on if anyone cares!

Series A, Episode 13 - Orac
BLAKE: No, we'd end up looking for each other as well as Orac and Ensor. Come on.
[Scene: Travis and Servalan still in the tunnels.]
TRAVIS: Let's check the map.
SERVALAN: We're almost there.

Claude Sonnet 4.0 describes the image as: "I can see two people in what appears to be a futuristic or sci-fi setting, likely aboard a spacecraft or space facility based on the sterile, metallic interior visible in the background. They're wearing matching green and white/silver colored outfits that have a utilitarian, space-age design - possibly uniforms or protective gear. Both individuals have dark, curly hair typical of late 1970s styling. The woman appears concerned or apprehensive, while th…

With my MastodonFedivers character I gathered for 30 minutes after consuming a pork pie( 15% yield in everything gathered!) I got these:
* 143 ore 5.0 - 35k
* 192 ore 4.0 - 16k
* 16 logs 4.2 - 9k
* 38 ore 4.1 - 7k
* 14 logs 4.1 - 1k
profit after selling it all:
* 68k
costs:
* 10k in repair costs(or 13k)
* 4k tp to ML
* 1 pork pie 5.3k
full T5 ore gear including Avalonian Pickaxe was used.

As a security community we have to make sure that people know about this vulnerability. Right now it's pretty easy to thwart, _don't keep your keys near the front door_. It's a simple countermeasure, but people have to see footage like this to understand. The threat is real and the gear to do this is pretty cheap.

Frictional Contact Network in Dense Suspension Flow

arxiv.org/abs/2505.22747

Frictional Contact Network in Dense Suspension Flow
Dense particulate suspensions often exhibit a dramatic increase in viscosity in response to external deformation. This shear thickening behavior has been related to a transition from lubricated, unconstrained pairwise motion to a frictional contact network (FCN) at high stresses. Here, we study the characteristics of the FCN formed during shear thickening to investigate the role of constraints, emphasizing the impact of resistance to gear-like rolling. We contrast the FCN formed by sliding fric…
