University of California, Los Angeles.
Jonny-Perlmutter, an elderly professor with white hair, was working on a part-time job in physics--
Reviewing for the renowned physics journal "Classical Gravitation and Quantum Gravitation."
Jonny-Perlmutter, a full professor in the Department of Mathematics at the University of California, Los Angeles, and an expert in astrophysics, gained widespread recognition in the field of theoretical physics for his theory of "Positive and Negative Energy of Celestial Bodies."
Perlmutter was 58 years old and about to retire.
By this age, it became extremely difficult to make any more significant achievements in academic research.
Perlmutter focused on education very early on, but he hadn't given up on scientific research completely; instead, he became interested in reviewing papers.
He truly loved the job of reviewing papers.
