Watching a few “how-to” videos on YouTube doesn’t make you an expert. To really know “how-to” change a tire, make puff pastry, or play the piano, you have to do it. Through experience, you discover new dimensions of your knowledge — from finding holes in your reasoning, to growing in flexibility and nuance, to even reassessing who you are and maybe even what you believe in.

In this episode, you’ll hear a story of such a discovery with guest Dr. Tom Rudelius, a theoretical physicist and string theory researcher with degrees from Cornell and Harvard.

Tom's story is shared in his new memoir: Chasing Proof, Finding Faith. This episode follows the arc of Tom’s book — how he and his twin grew up, to the lie detector test that sparked his faith in Jesus, to the deepening of his faith even in the face of mental illness, anxiety, and doubt.
