One way Dickinson conveyed abstract concepts was by linking objects or parts her poems with an em dash, a portal into fractured, nonlinear thought unlike any other. Poem via @poetryfoundation.bsky.social

What is information? What does it mean to say the universe or a biological system computes? Wheeler in the late eighties wrote a remarkable paper. In it he developed the idea information came before matter—“it from bit“. . .More on Babel Blog. jessicaflack.wordpress.com/blog

Interested in emergence + computation in nature? Please visit the Bio, Research, Pubs, and Babel Blog pages of my website. jessicaflack.wordpress.com My foci tend to be on collective phenomena at the intersection of bio, cognitive neuroscience, consciousness, CS, information theory, + physics.

"Now and again a poem comes like that, like a ball kicked in from nowhere: in this case, I was completely absorbed in writing one of the last of the Oxford lectures when I had this quick sidelong glimpse of something flying past; before I knew where I was, I went after it."

The question of how biological systems from cells to organisms 'overcome' spatial or apparent information processing constraints to estimate global variables, compute macroscopic states, or just 'see' the big picture—the forrest + the trees—is one of biology's most dismissed yet important questions.

Wheeler, who cites Wiliam James, wanted to know how a vision of one world arises out of the information-gathering activities of many observer-participants. Essentially abt collective computation, it's remarkable to think this question could unite physics + biology + even AI. 1/n

Jim argued that a sense of time flowing arises from computation—as an entity computes an action (output) from a perception (input), w each image of the environment that an entity captures constituting its 'present'.

Wheeler does't mention Dennett in his paper but of course Dan's early work on the intentional stance is relevant.

Einstein writes to Wheeler about delivering a paper of Wheeler's to von Neumann. A close-up of topological shortcuts—does the sketch imply heterogeneous density or clustering? Wheeler's black hole drawing and hourglass emergence seem to bare some overlap. 🤔
