Last week I really enjoyed reading Witness to Grace, brief autobiography of John Goodenough. I knew of him for his scientific work in solid state physics and chemistry because some of it overlaps with my research. He is best known for inventing lithium rechargeable batteries. Although aged 91 he is still publishing papers!
The book mixes his spiritual history with his scientific career. He came from a family that had a church background but his parents "outgrew" religion, seeing it as a superstitious and psychological crutch. But experiences while a student at Groton school eventually led to his conversion while doing a Ph.D at University of Chicago. His family was not impressed.
The scientific parts of the book may not be accessible to some readers, without the necessary background! Nevertheless, it is a compelling story and a moreover a moving witness to the grace of God, as revealed in Jesus.
