The possible collapse of twitter has made me super sad and reflective about what this site has meant to me and how it shaped my work as a literacy researcher and educator and now as an early platform ceo.

i have 45 minutes and i'm about to tweet my guts out.
i was thinking of pitching like a "eulogy for twitter" to @TeenVogue but i'm gonna tweet first instead, unroll it later, and see what i can do with it.

this is off the dome first draft material, we'll see what themes come out. stay with me.
i want to think through how i've used twitter since i made my first account in 2008, how it impacted my teaching and research, what i wish this site could've been, the rise of the multiracial patriarchy whitelash, and ultimately how and why i founded @germnetwork this year

"The 21st Century Question: Emergently Engineering the Future"

Follow this 🧵 today and tomorrow for highlights from our 2022 #AppliedComplexity Network and Board of Trustees Symposium:

santafe.edu/events/annual-…

#Web3 #Cities #Polarization #EmergentEngineering #Decentralization
We start with a talk by SFI President David Krakauer:

"Would anyone care to guess why we're so GOOD at building transistors and so CRAP at designing drugs?"

"This thing [points to transistor] lives in a centralized system. This thing [points to cancer drug] lives in US."
"I'm going to pick on economics, because we like to do that at SFI. 'Ooh, look at that cover! So techy. Global, heat maps...' But here's 'Networks' [in the textbook]. THAT'S IT. Here's '#ComplexityEconomics.' NOTHING."

"#Emergence, #SelfOrganization, & #Complexity"

🧵 In today's SFI Seminar, Visiting Scholar @cgershen presents the second in his series of talks on core concepts in #ComplexSystems science, streaming now:

"In high school #physics class you are taught that with the initial conditions of a system, you can predict its future states. In #complexity, this is not so...it means #reductionism is not appropriate, #Platonism is not appropriate..."
- @cgershen
"You can see a layer of circuits computing something. What is it computing? Itself. In a 248x248 array, you can program the #GameOfLife inside the game of life. Computers allow us to explore #Complexity, and it's no surprise complexity became a science in the 1980s."

Okay. So I haven't slept for 2 days, I'm running on Adderall, Coffee and Cheeeeeescake, Gromit.

Now that I set the stage, I need to document some stuff here before I crash. Because: I'm seeing things 'from my archives matching realtime' that I need to save before, 'smoked'. Image
Awhile back...

...I did a thing on top of a lot of other things and then more things since those things.

What FOLLOWS is a #MindDump jumbled out-of-sequence set of affinities around 'a Theme'

Dan killed his 'name' account (Known-Known) and created a completely new one (Identical User ID).

It hasn't changed, externally, from immediately after it was created. '3/0' Zero Tweets. Behind the curtain? Who knows. Image

🧵 Group project presentations begin today for the 2022 SFI Complex Systems Summer School! We will share bits and pieces over the next two days...

#CSSS #ComplexSystems
First talk this morning by a team including @JenniferKBriggs @gatesdupont @maikemorrison @davidogara_ @simon_rella Ian Harryman & Haoyuan Luo on their contagion model ("Hopefully you'll see this published later" may as well be the official slogan of this summer school)
Our next group considers online #pornography a strangely under-examined domain for quantitative research & wants to bring #digitalhumanities approaches & multilayer network analysis to bear on it. @gulsahakcakir @AnaVybor @thomas_bssnt @prt_thibault @simon_rella

@ucdavis @theNASciences @eco_hastings "The long-term behavior of the #epidemic is not what you want to focus on. Let's focus instead on dynamics at shorter timescales."

🌍 Our 2022 #Science Board Symposium on "The #Emergent #PoliticalEconomy or #ClimateChange" kicks off with opening remarks from President David Krakauer.

Follow this 🧵 as we provide live coverage of this event all day...
"For those of you who think behavior change can prevent #ClimateChange...behavior WILL change when climate changes. Shutdowns from the pandemic resulted in a reduction of #C02 emissions of about 7.5%."
- SFI/@Harvard Prof Dan Schrag opens our speaker series today
"We *used* to talk about #ClimateChange used to be something that would happen to people in Bangladesh fifty years from now."

Re: #ClimateJustice,
"Children born today are going to deal with climate change they had no role in causing."

🧵 Global catastrophic and existential risks: the weightiest complex phenomena?

"Our job is to think about how humanity can have a happy ending...about how GOOD it can be."

- @anderssandberg of @FHIOxford speaking at SFI today:


#AIEthics #Biosecurity
"The idea that humanity actually *could* go extinct required a lot of ideas to come together. First you needed to know that species go extinct. This wasn't clear until [the discovery of fossil Mastodons]."
- @anderssandberg of @FHIOxford at SFI today:

"It's not just that the end of the world could be caused by a bad political decision. In principle, the *right* political decision or technology could *avert* these risks. In the 19th C, it was a considered merely a matter of natural causes."

On #InternationalWomensDay we'd like to pause and celebrate just a small slice of the enormous contributions to science women have made here at SFI.

Read the thread below for links to some of their own favorite research papers, and a few nominated by other SFI faculty members:
First off, these papers on #FoodWebs led by our VP for #Science, Jennifer Dunne:

[@royalsociety Proceedings B]
royalsocietypublishing.org/doi/10.1098/rs…

[@PLOSBiology]
doi.org/10.1371/journa…

...and this interview she did for @QuantaMagazine:

This week at SFI: "#Complexity and the Structure of #Music: Universal Features and Evolutionary Perspectives Across Cultures", an #interdisciplinary working group assembled to explore new frameworks for understanding music. Stay tuned for highlights!

santafe.edu/events/complex…
"Every pitch class set is connected to every other pitch class set."

– @mbnUNT, co-organizer of this week's #musicology working group, presents on how to understand the #topology of #harmonic structures in music with #network diagrams (e.g. Pic 4 with #JSBach's BWV 66):
Once you represent a musical composition as a network, it is possible to examine the evolutionary dynamics of its harmonic content over time, as explained by @mbnUNT in his opening talk for this week's SFI #musicology working group.

(Ironically, this #Beethoven is #scalefree:)
