Query: Michio Kaku's Parallel Words

Dr. Kaku's presentation of the subject matter is well written for the average person to understand.I'm not a student but I love to look at scientific material that "expands" my thinking. Dr. Kaku'swriting delivers in this respect.I have enjoyed Parallel Worlds and would look forward to buying more of his titles.
