My dear friend, mentor, and PhD advisor, Barry Sinervo, passed away last night. Barry taught me that having the audacity to attempt challenging things is worth it because you might just succeed. He was humble where it counted, always open to scientific ideas that contradicted his own–even if convincing him took a few attempts. Like other giants of science, Barry exemplified how creativity and lateral thinking are just as important to scientific advancement as empiricism and critical thinking. His fluid ability to make connections between the languages of creativity, math, nature, and persuasion was a phenomenon to witness. I miss him dearly.
