Will life be different on other planets? Can we build living systems that depart from what we know? In terms of the logic, maybe not. Check my last paper with several @sfiscience colleagues on the "Fundamental constraints on the logic of living systems" preprints.org/manuscript/202…

@jt_pentz @wc_ratcliff You're a-ma-zing, congrats 🎉🎉🥳

It was incredible to work in Will's group at Georgia Tech. I was very lucky to work and learn from such an amazing scientist and person. Thanks for everything @wc_ratcliff ! Here is a picture from the day I defended - what a day!

My final paper from my time in @wc_ratcliff's group was just published at @eLife! This paper explores the consequences of early multicellular life cycles on the evolution of multicellularity. For a great big picture overview, see this great thread by Will. 1/

@VicioNez Bueno, sin ser experto en los temas, "a mi se me hace" que sí, pero he leído mucha controversia, sobre todo lingüística. Tienes un link de tu tesis de maestría? Gracias por la info 🙏🏼

@PedroM_Z Solo los chovinistas no aceptan la amplia evidencia desde el preclasico hasta el Posclásico twitter.com/VicioNez/statu…

NADIE dudaba, durante el XVI, de la existencia de la metalurgia mesoamericana. Los españoles requirieron este conocimiento para suplir la falta de hierro. Todos los cronistas, Sahagún, Bernal, Cortés, Torquemada, etc., refieren, de una u otra manera, el trabajo nativo de metales.

@VicioNez Ahhh, eso era lo que tenía entendido, pero desde luego el proceso de difusión desde los Andes parece controversial, desde lo que he leído, porque implicaría otros tipos de contacto cultural/geográfico/lingüístico sin evidencia sólida (aunque depende de a quién le preguntes 😂)

@PedroM_Z Difusión. La metalúrgia solo surgió en los Andes y de ahí a occidente y de ahí a toda Mesoamerica

@VicioNez Es decir, me queda la duda si fue difusión cultural, o descubrimientos independientes.

@PedroM_Z Durante el Posclásico tardío el bronce era ampliamente usado en toda Mesoamerica twitter.com/VicioNez/statu…

@VicioNez Interesante, tienes un link a tu tesis? Gracias ✌🏼

@VicioNez ¿Era el cobre usado por todas las culturas? Pensé que tenía principal uso/dominio en la cultura Purépecha

Dice Dupaix: Los habitantes de la provincia marítima de Zacatollan, situada entre Acapulco y Colima, preparaban dos tipos de cobre, uno duro y afilado y otro maleable: el cobre duro se utilizaba para fabricar hachas, armas e implementos agrícolas... upload.wikimedia.org/wikipedia/comm…

At a rate of 1 box consumed per day, we can see that @sfiscience folks are connoisseurs 👌🏼

Just to inform the public that the superior candy has just dropped at the Santa Fe Institute 👌🏼

@FelixJBerrios I wrote a thingy that helped me, although directed to scicomm, I'd say most principles apply similarly: theopennotebook.com/2022/10/25/don…

Any tips on getting over writer’s block. Im struggling to write anything at all. I feel stuck and overwhelmed 😭 help

@greg_m_priest @ricard_sole @manlius84 @_AlexArenas I believe he elaborated this in "The Logic of Paradise", a lecture available on the Internet, given as his personal account of what happened during Chile's coup (1973)

@PedroM_Z @ricard_sole @manlius84 @_AlexArenas Do you happen to remember where V said that? I’d like to follow it up.

What is complexity? What kind of approach is needed to define it? Here's a 1977 paper by Robert Rosen, one of the pioneers of System Science, discussing how information, error and scale are central to this problem, tandfonline.com/doi/pdf/10.108… @manlius84 @PedroM_Z @_AlexArenas

@waynelforBernie @ricard_sole @manlius84 @_AlexArenas These are complementary. Embodiment is clearly important (in Rosen terms, the "realization"), but this embodiment has been given way too much attention, while the organizational/complexity account, is barely scratched. As you said, embodiment constrains. Complexity expands.

@PedroM_Z @ricard_sole @manlius84 @_AlexArenas Ultimate (M,R) while substrate independent is about the closure of the set of "mechanical models" of the system its not clear to me whether phenomena like bioelectric networks are encompassed by something like Louie " repair bundle" . May just be I haven't figured it out yet

@greg_m_priest @ricard_sole @manlius84 @_AlexArenas Exactly. Francisco Varela made a similar point later, when he said that there's nothing "out there" (in nature) which is simple or chaotic, all is in our epistemology.

@ricard_sole @manlius84 @PedroM_Z @_AlexArenas I need to get behind the paywall, but I quite like the idea (as seems implicit in the abstract) that we can frame the complexity of a system in epistemological or methodological terms—in terms of what kinds of approaches are necessary or fruitful to study it.

@waynelforBernie @ricard_sole @manlius84 @_AlexArenas Levin's work is interesting in its own right, but giving primacy to "bioelectricity" would miss the point that life is not linked to any given material substrate/process. And constrains our vistas of complexity. This already happened with molecular biology ("biomolecularicity").

@ricard_sole @manlius84 @PedroM_Z @_AlexArenas See especially the work of Mike Levin's group at Tufts

@cgershen @evgenymorozov Also binge-listened this on a long flight. What an amazing story 👏👏

Just finished binge-listening The Santiago Boys by @evgenymorozov. Cybernetics, cold war, terrorism, idealism, power struggles, and much more, centered on Chile 🇨🇱 50 years ago. Highly recommended. the-santiago-boys.com

@michaelgarfield Life doesn't just "find" A way, life *creates* ALL ways 🌵🏝️

Life doesn't just find A way. Life finds ALL ways.

Also heard/met Gustavo Santaolalla & Diego Lorenzini 😁 🎹🎤🎧

I guess the bird app is in its last stretch, but I'll still report that I had a great week visiting the groups of @ricard_sole and @svalver. Very stimulating conversations 👌🏼🤯

@cgershen Maybe with enough (and interesting) feedforward 😉

Can you adapt without feedback?
