Dr. Yasushi Nozawa was born in Tokyo, Japan. He came to the United States and received M.S and Sc.D. degrees in Aeronautics and Astronautics from MIT. After his retirement from engineering, he began writing as a second career. He writes in two different fields: the genre of biographical fictions and memoirs, and science and religions, specializing in the rational explanation of religious phenomena. He has written several dozen articles in both fields for periodicals. He has also published, "Temporary Permanence" subtitled, "My Life in America: Humorous Short Stories Based on Experiences Of a Japanese Engineer," a collection of biographical short stories written under the pen name, Yashi Nozawa. Many readers of the book have praised his O'Henry-style writing and made it a local best seller. "The Spring Connections: Easter, Passover and Others," is his second book, the first in the field of science and religion. The book is about the deep-rooted tradition of spring celebration and its interaction with calendar systems. He also disclosed his new interpretation of the meaning of the Israelites' Exodus in the book.
