Turner is now an ordained Zen monk, yet he is also still a physicist, working for a company that makes helium neon lasers. I asked him if he felt any tension between his science and his spiritual practice. “I don’t feel there’s a contradiction. Yet what happened at Hopkins has influenced my physics. I realize there are just some domains that science will not penetrate. Science can bring you to the big bang, but it can’t take you beyond it. You need a different kind of apparatus to peer into that.”
