This work provides a new language for relating embodiment, energetic cost, and memory, with design implications for both robotics and biology.

We found a fundamental trade-off: the most energy-efficient action leaves no memory behind. Any action that creates a path-dependent memory trace inevitably requires extra energy, a principle we call the "cost-memory duality".

Tangential Action Spaces: Geometry, Memory and Cost in Holonomic and Nonholonomic Agents Living systems balance energetic efficiency with the capacity for path-dependent effects. We introduce Tangential Action Spaces (TAS), a geometric framework that models embodied agents as hierarchies ...

Our new paper introduces Tangential Action Spaces (TAS), a geometric framework for understanding how embodied agents translate goals into physical actions.

Experimenting with some of my astrophotos. Here is one. Sharpless sh2-119. Removed almost all stars and gave the nebula more breathing space and depth. #Astrophotography

Sharpless 119, is a large patch of emission in the constellation Cygnus and lies some 2200 light years away. It’s only 2-3 degrees away from the North American and Pelican Nebulae, so is often overlooked.

Tonight dancing with the stars ✨

The fact that I get highly polarized reviews (paper submission) for a new idea tells me: I am on to something! I’ll continue to work even harder on that idea. #science

The Western Veil Nebula NGC 6960 ✨

Capturing ancient stellar violence in the constellation Cygnus! This shows the aftermath of a massive star that exploded over 20,000 years ago.

Part of a larger mosaic project to capture the entire Cygnus Loop! 🌌

FSQ-106EDX4 with ZWO 2600 mm (Mono). 16x5’ Ha, OIII, SII each. 15x30” R,G,B each (for stars).

My shot of the incredible Veil Nebula! ✨ It's the ghostly remnant of a star that exploded thousands of years ago. So much beauty in our universe.

Thanks for the great work!

My latest experiment explores a somewhat different approach to PID control. By integrating neural networks, the system can dynamically adapt to changing conditions for improved performance. Learn more about the underlying concepts in the linked article. #AI

#ALife. Submitted yesterday. Let’s see.

Eigenvalues go crazy.

Thanks!

ALIFE 2025: The Artificial Life Conference, 6-10 October, Kyoto, Japan ALIFE 2025’s theme is 'Ciphers of Life', exploring the many ways that life encodes information, creates internal languages, and interacts in encrypted ways with its environment.

Happy Friday! Here is a shiny new update for you.

🎊🎊 Our LaTex template just dropped! 🎊🎊

Weekend. Time for reflection. What can we know?

It’s one thing to see my images on a screen. It’s another thing to see it tangible on a print out (NGC 7000). The universe is awesome. Have a nice weekend.
#reflections #Astrophotography

After falling into a rabbit hole of numerical instabilities in my simulations, I finally found a way out. What an awful journey for the last few months. Peace now! Have a lovely evening.

Early career researchers, tech enthusiasts, students, and people with half-baked ideas are especially encouraged to join! DM me to sign up!

Thanks for sharing!

Hey @wveal3.bsky.social, that's just an iPhone shot. Have a nice day.

Have a nice weekend. Time for reflection. #moon #astrophotography

How do biological systems achieve adaptability and resilience with simple, local interactions and no central control?Together with Michael Levin we explore these processes in regeneration, offering insights that could inspire AI systems to become more robust and flexible.

Save the date!
The annual #Conference on #ArtificialLife - #ALIFE2025 will take place in the heart of Kyoto, Japan, from 6-10 October 2025. The conference logo, official website launch, and more details coming soon!

Nice one.

Oiii 3nm Seagull Nebula. Pretty faint but with hundreds to stack, there may be some more data here than meets the eye.

Ha 3nm 5-minute exposure

Sii 3nm 5-minute exposure

Seagull Nebula is available to members. ~62GB of full frame mono 3nm SHO data! I Can't wait to see what people are able to process with this data set! Some Example SHO Subs below. 🔭
