I had been closely working with Dr. Britton Chance from 2005-2010 on imaging mitochondrial redox state in cancer and stem cells. I had also learned much from him in daily work and personal life. Here I would like to share some of my memories and experiences including (1) Great science is not necessarily done with top-grade expensive instruments; (2) Brit was genuinely interested in and dedicated to science; (3) Brit's attention to detail and timely action; (4) Brit's open-mindedness; and (5) Brit being modest, appreciative, and caring for others.
