RIP Erik Bollt (1967–2025)

My collaborator Erik Bollt died suddenly and unexpectedly last Sunday (the 7th). Erik is a well-known applied mathematician, and he was especially in the applied dynamical-systems community. Erik and I wrote two papers together, including our paper on mathematically modeling cow synchronization.

You can read about Erik's research on his web page and his Google Scholar page.

There will be a memorial article at some point.

Jeff Kent Elected to Baseball Hall of Fame!

Second baseman Jeff Kent has been elected to the Major League Baseball Hall of Fame by the Era Committee (which is the current version of the Veterans Committee. I am pleased that Kent is finally in the Hall.

Carlos Delgado did surprisingly well in the voting, so it sounds like he'll eventually make the Hall of Fame. Notably, Dale Murphy and Don Mattingly did not get enough votes (despite the fact that the Powers That Be seem to want them to be selected), and I agree that they should not be elected. Finally, I hope that Gary Sheffield, Barry Bonds, and Roger Clemens eventually make the Hall of Fame, but I won't be holding my breath (especially for the latter two).

"Clustering-Induced Localization of Quantum Walks on Networks"

One of my papers came out in published form today. Here are some details.
