## Some Collected Quotes

- „Many people have worked on it and vanished without a trace.“ (George Elliott, about the quasitrace problem. Workshop on Operator Algebras and Applications: Connections with Logic, Fields Institute, Toronto, August 2023. According to Elliott, this is a quote of Kadison.)
- „You have to allow for C*-algebras without projections. But that’s another day at the office.“ (George Elliott, about the generalization of a result from simple unital to simple projectionless C*-algebras. Workshop Cuntz semigroups, Münster, July 2021.)
- „I am not a scholar, but I get around.“ (George Elliott, when discussing with the audience whether the uniqueness of the commutation relations and the characterization of compacts by a unique irreducible representation was due to von Neummann in 1931 or Naimark in 1951. Barcelona Conference on C*-algebras: Structure, Classification and Dynamics, June 2017)
- „No animals are killed in this process.“ (George Elliott, about a classification functor that doesn’t „kill“ any automorphisms. Barcelona Conference on C*-algebras: Structure, Classification and Dynamics, June 2017)
- „It’s worse than nothing. Apologies to the experts.“ (George Elliott, towards Ilijas Farah about the shortcomings of the quotient R/Q as a topological or Boral space. Barcelona Conference on C*-algebras: Structure, Classification and Dynamics, June 2017)
- „I would think there is more than one way to get dressed in the morning, and it would still be satisfactory.“ (George Elliott, When discussing canonical vs. natural, and that natural does not mean unique. Barcelona Conference on C*-algebras: Structure, Classification and Dynamics, June 2017)
- „Life’s too short to worry about nonseparable things.“ (Cornel Pasnicu, at the Barcelona Conference on C*-algebras: Structure, Classification and Dynamics, June 2017. According to Pasnicu this is a quote of Mackey.)
