Paul G. Hewitt popularized this approach with his textbook Conceptual Physics: A New Introduction to your Environment in 1971. In his review at the time, Kenneth W. Ford noted the emphasis on logical reasoning and said "Hewitt's excellent book can be called physics without equations, or physics without computation, but not physics without mathematics." Hewitt's wasn't the first book to take this approach. Conceptual Physics: Matter in Motion by Jae R. Ballif and William E. Dibble was published in 1969. But Hewitt's book became very successful. As of 2022, it is in its 13th edition. In 1987 Hewitt wrote a version for high school students.
