RIP Mitchell Feigenbaum (1944–2019)

Mathematical physicist Mitchell Feigenbaum, known for his work on the period-doubling route to chaos in the logistic map and other nonlinear phenomena, died over the weekend.

Here is his wikipedia page.

Update (7/18/19): Today, The New York Times published an obituary of Feigenbaum. The first picture in it is fantastic!

Update (7/23/19): Here is a very nice blog entry by Stephen Wolfram about Feigenbaum, his constant, and other bits of Feigenbaum's history.)
