Mitchell Feigenbaum passed away - jwdietrich - 07-04-2019 07:31 AM
On June 30, 2019, Mitchell Feigenbaum, one of the outstanding pioneers of chaos theory, died at the age of 74. In 1975 he discovered with an HP-65 calculator that the ratio of successive distances between bifurcation events tends to a constant value, which was later termed Feigenbaum constant. This was one of the founding events of chaos theory and nonlinear dynamics. R.I.P. RE: Mitchell Feigenbaum passed away - TomC - 07-05-2019 03:38 PM
Dam; I was hoping to find him for a conference presentation. I too was fidgeting with iterative calculations on my 65 back in 1974. He took things a bit farther than I did! TomC RE: Mitchell Feigenbaum passed away - Jonathan Busby - 07-05-2019 04:43 PM

This was one of the founding events of chaos theory and nonlinear dynamics. This is indeed sad :'( . He died so young -- my grandfather recently died and he was almost 100. I was also sad when Michael Golomb died at 98. He was the person who came up with all Purdue's higher math Problems of the Week. Apparently though, there is still a backlog of problems that have yet to be published as Michael Golomb was so prolific. R.I.P. to both of them.

This is truly sad. I remember discussing him with TomC some HHCs ago. Discovering a natural constant with an HP 65 is a unique achievement. He tells the story here in an acessible way https://permalink.lanl.gov/object/tr?what=info:lanl-repo/lareport/LA-UR-80-5007 RIP Prof Feigenbaum Felix RE: Mitchell Feigenbaum passed away - Eddie W.

Condolences and comfort to the Feigenbaum family. |
