Deepak Chopra (Hindi: दीपक चोपड़ा; born October 22, 1946) is an Indian-American author and alternative medicine advocate. A prominent figure in the New Age movement, his books and videos have made him one of the most well-known and influential figures in alternative medicine. His discussions of quantum medicine have been described as technical jargon—”a rambling, scientific-sounding rambling” that drives those who actually understand physics “crazy” and “redefines error.”
