Introduction

Six years ago, Afonso Bandeira and Shuyang Ling were attempting to come up with a better way to discern clusters in enormous data sets when they stumbled into a surreal world. Ling realized that the equations they’d come up with were, unexpectedly, a perfect match for a mathematical model of spontaneous synchronization. Spontaneous synchronization is a phenomenon in which oscillators, which might take the form of pendulums, springs, human heart cells or fireflies, end up moving in lockstep without any central coordination mechanism.

Bandeira, a mathematician at the Swiss Federal Institute of Technology Zurich, and Ling, a data scientist at New York University, dove into synchronization research, obtaining a series of noteworthy results on the strength and structure that connections between oscillators must have to force the oscillators to synchronize. That work culminated in an October paper in which Bandeira proved (together with five co-authors) that synchronization is inevitable in special types of networks called expander graphs, which are sparse but also well connected.

Expander graphs turn out to have a slew of applications not only in math but also in computer science and physics. They can be used to create error-correcting codes and to figure out when simulations based on random numbers converge to the reality they are trying to simulate. Neurons can be modeled in a graph that some researchers believe forms an expander, due to the limited space for connections inside the brain. The graphs are also useful to geometers who try to understand how to traverse complicated surfaces, among other problems.

[What I said:]

I must admit I’m disappointed, Tjin. I know that my critique and recommendations were just one comment on your – as you say – viral LinkedIn post. But I hoped that from me or someone else you would have engaged with some of the points therein.

Here were my comments:

https://www.linkedin.com/feed/update/urn:li:activity:7130064373363990528?commentUrn=urn%3Ali%3Acomment%3A%28activity%3A7130064373363990528%2C7130307803994279936%29&dashCommentUrn=urn%3Ali%3Afsd_comment%3A%287130307803994279936%2Curn%3Ali%3Aactivity%3A7130064373363990528%29

I think you’ve ended up with a toolkit that is flat – not engaging with some of the rich depth and complexity of systems | complexity | cybernetics – difficult – some of the Systems Dynamics stuff is amongst the hardest to learn and use well – and that includes a lot of interesitng stuff that doesn’t really relate to the field.

Anyway, I do appreciate all the work that goes into something like this (I’ve been working away at www.syscoi.com for years) and I will stay tuned – on the paid subscription – for a couple of months to see where yo utake this!

What Systems Thinkers Can Learn From Historical Synthesis | Dr. Michael Bonner | Systems Thinking Ontario 2023-11-13

For the November 2023 Systems Thinking Ontario session, historian and policy advisor Dr. Michael Bonner was invited for an interview by Zaid Khan.  In organizing the sessions, we’re trying to avoid the trap of systems thinking becoming a discipline, through learning with a sweeping-in process.

The session opened on a map of The Sassanid Empire c. 620 CE, also known as Second Persian Empire, a high point for the Iranian civilizations before the early Muslim conquests of the 7th–8th centuries.

Three (!) new books from Otto Laske

Vol 1 https://link.springer.com/book/10.1007/978-3-031-40332-3

Vol 2 https://link.springer.com/book/10.1007/978-3-031-40985-1

Vol 3 https://link.springer.com/book/10.1007/978-3-031-40339-2

Message from Otto:

A New Concept of Advanced Systems Thinking

Highlights

  • Focused on the mental processes of the systems thinker, the books introduce a paradigm
    shift in advanced systems thinking: rather than fixating attention on systems

hypostatized by the thinker on purely logical grounds, the books lay bare the thought-
form structure of the thinker’s real-time movements-in-thought that led him to

hypostatize the system in question, thus making visible the ‘absences’ in the thinker’s
thought that need to be repaired.

  • By centering on the systems thinker’s own mental process and its cognitive-
    developmental structure, the books outline an assessment methodology for judging the

quality of individual system thinkers’ process in terms of the complexity and maturity of
their thinking.

  • Thereby, they deliver the foundation for empirical studies in systems thinking as a part of
    studies in adult cognitive development; the books also lay the foundation for teaching
    advanced systems thinking in a self-reflective manner, not primarily for “solving
    problems” (which are always a function of the thinker’s thought maturity), but for
    measuring and boosting the thought complexity a thinker is presently capable of.
  • The books thus amount to an epistemology of advanced systems thinking that highlights
    the latter’s limitations when it is conducted in purely logical terms, simultaneously
    showing that logical thinking, (in Western cultures) mature at 25 years of age, naturally
    evolves into dialectical thinking over the lifespan.
  • The books are based on Laske’s Dialectical Thought Form Framework (DTF, put in place in
    2000), which is continued to be taught in international cohorts at the
    Interdevelopmental Institute (https://interdevelopmentals.org/services/).
    Three New Books on Advanced Systems Thinking
    by Otto Laske, known as Inventor of New Thinking
    Tools, have appeared at Springer

Volume 1: Approaching Real-World Complexity with Dialectical Thinking (ISBN 978-3-031-40331-6)
Volume 2: How to Measure and Boost Thought Maturity (ISBN 978-30031-40984-4)
Volume 3: Manual of Dialectical Thought Forms (ISBN 978-3-031-40338-5)

  • The books spell out and interpret validated empirical outcomes of adult-developmental
    research in cognitive development over the life span, — a discipline now 25 years old but
    curiously kept out of the systems thinking mainstream which therefore lacks a reflexive
    meta-level.
  • The books articulate the pedagogical foundations of 20 years of undergraduate and
    graduate instruction in advanced systems thinking at the Interdevelopmental Institute
    (IDM; www.interdevelopmentals.org), delivered in international cohorts in English,
    French, German, and Spanish.
  • From a historical perspective, the books fuse insights of the Frankfurt School and the
    Harvard Kohlberg School as well as integrate cutting-edge insights deriving from R.
    Bhaskar’s and M. Archer’s Dialectical Critical Realism.
    Having proven their worth in practice, they are ready to be used for teaching and examinations
    at colleges, universities, think tanks, and in programs of executive and team development.
    I would be happy to mentor your staff in the novel subject of the three books.
    Sincerely,
    Otto Laske, Founder and Director, Interdevelopmental Institute (IDM)

An Introduction to Feedback (1960) – YouTube

[Shared on the American Cybernetics Society email list by Paul Pangaro]

Eames Office

The principle of feedback — the cycle by which performance is measured, evaluated against desired results, and corrected for future performance. Made for IBM, Introduction to Feedback was one of a series of films proposed by the Eames Office to explain computers and the principles underlying their operation. Script by Charles Eames Narrated by Vic Perrin, Music by Elmer Bernstein 10 minutes, 40 seconds.

Launching “Systemic” – A game for applying systems change thinking to policy 

Posted by: vanessalefton and alexfleming, 15 November 2023 – Categories:Policy Lab

This blog launches “Systemic” – a game that simulates how policy-making systems function and possible shifts that can be made to improve policy outcomes. Systemic has been inspired by the world of board games, and was co-created by Policy Lab and Matteo Menapace, the co-author of ‘Daybreak’. It forms part of our learning from a project aiming to shift complex systems around multiple disadvantage with the Changing Futures Programme. Serious games are one of Policy Lab’s new experimental methods, set out in the launch of our experimental innovation strategy last year.
