An article in the 19 February 2020 Harvard Gazette, contains one of a series of articles called ‘Focal Point’ in which Harvard faculty respond to a fundamental question: ‘If you were to write a letter to your students, what would you want them to know?” In this edition, the faculty member is a lecturer in the physics department and a co-director of Graduate Studies for Physics, Jacob Barandes, and his remarks warrant reading and can be found at Harvard Gazette.
