Continuing posting on making comics accessible for blind/low vision readers, this part of our comic shows 6 possible ways of translating just a single panel, to really illustrate how one size doesn’t fit all needs. Accessibility is messy & an artistic act itself! spinweaveandcut.com/mitcomic/
A part of a comics page, it mostly shows a cube that represents six views of the same comics panel (we can only see three because this is flat paper, but can infer all six sides look the same) with a Batman like character swooping down on some villains. Emanating from it are voice captions that describe this panel in different styles - minimalist to radio drama and others.

In our work agents develop the ability to trust differentially other agents based on the outcome of their decisions. A complex society and hierarchy can emerge. It is not mandatory. There is a phase diagram based on the interactions between agents. These can be tuned to avoid collectivism!! 🧪⚛️

Assistant Professor of Quantitative Political Methodology (Tenure-Track)
The Department of Political Science at Northwestern University invites applications for a full-time position in Quantitative Political Methodology at the rank of Assistant Professor, tenure-track, to begin Fall 2027. We emphasize methodology with a strongly applied perspective: successful candidates will maintain an active, independent research program that includes methodological contributions in their own right, while also teaching quantitative research methods courses at the undergraduate and graduate levels and applying those methods to substantive questions in their area of expertise. We are especially interested in candidates whose work bridges data-driven/computational approaches with design-based inference, though we welcome applicants making cutting-edge contributions in either of these traditions or in other areas of political methodology. Successful candidates' substantive research agendas may be in any area of political science or may cross boundaries; as with all Northwestern faculty, successful candidates will be expected to provide service to the department, the university, and the profession.Aerial photo of Northwestern's beautiful lakeside campus with political science's new building circled

Twice a year, Hawai'i experiences a strange moment where the sun appears to be exactly overhead & anything that is completely vertical casts no shadow. Let's learn about Lāhainā Noon, subsolar points & 'Kau ka lā i ka lolo', meaning "the sun rests on the brains."
From a Reddit forum, a photo of a can of coconut milk with a blue label, papyrus text and a flip-top, on a sidewalk.  It seems to hover because there's no visible shadow.  The pavement is sort of unevenly colored, with bright spots, and the grass along it is green and lush.

Finally finished @philipcball.bsky.social's wonderful "How Life Works"! When I hit the part on the 2nd Law felt compelled to share my comic on Entropy from a few years back, bits of which I'm expanding on in the new work (& one reason I read this brilliant book!) spinweaveandcut.com/sketching-en...
a single page comic about entropy - how everything tends towards disorder, and those brief moments when things go against that downward flow - specifically life. Opens with linear rod of small rectangular panels on how things get more disordered. 

The rest of the page has a much less regimented structure. In the background is a river in black that flows from upper left to lower right end of page. Over it is a spiraling panel structure that has the primary narrative. This begins with a trio of narrow rectangular small vertical panels arranged in descending order. Within them a sequence where a ball falls down stairs. A white arrow stems from the panels and points into the Y of the word yet In large black letters. This moves reading flow across the page to the right side where there are three mirroring vertical panels to the left side except these are arranged in ascending order left to right. Inside them are images of swirls - perhaps a cyclone viewed from space. And then, on the right edge, the panels align with the arm of a spiral of panels. And now we see a sequence depicting swirl of gases to birth of a star, a diagram of new elements forged in its core to star and  planet (earth) orbiting. Then swirls of clouds on earth, lightning, rain, water, volcanoes and spiraling to the center: circular panel with caption “swirls keep forming”. Now spiral path reverses from the center to show organic molecules, then dna. Outside the panel path a maple “helicopter” spirals into the panels, to sprout and grow into a tree

This second spiral arm comes out of the center and returns to standard reading order. A river has flowed behind the whole page and in the last panel, a person is seen putting a finger in creating swirls in the water - as life and stars are swirls drawing from entropy's downward stream...
