Vollis Simpson was a man with a curious mind—always eager to know how things worked and how to fix them. Growing up on a farm in North Carolina, he loved to tinker with machines. And when he served in the Army Air Corps during WWII, Vollis kept right on tinkering. His ingenuity allowed him to build things no one would have thought to create from scraps—a washing machine out of airplane parts and a motorcycle out of a bike. After the war, his passion for metal creations picked up speed—turning into a whirlwind of windmills as far as the eye could see. Luckily, Vollis’s fanciful and colorful windmills have been preserved at a park in Wilson, NC, where visitors can behold his magnificent and towering creations forever whizzing in the air.","forthcoming":false,"isbn13":"9781662680410","publication_date":"20241112","publisher":"Astra Publishing House","slug":"whirligigs","subtitle":"The Wondrous Windmills of Vollis Simpson's Imagination","title":"Whirligigs"},"discovery":{"categories":{"all":[{"bisac_code":"JNF061010","confidence_band":"medium","label":"Inventions","score":0.7137,"source":"bisac_hint_model"},{"bisac_code":"JNF051120","confidence_band":"low","label":"How Things Work","score":0.6927,"source":"bisac_hint_model"},{"bisac_code":"JNF007090","confidence_band":"medium","label":"Science & Tech Biographies for Kids","score":0.6922,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"JNF061010","confidence_band":"medium","label":"Inventions","score":0.7137,"source":"bisac_hint_model"},{"bisac_code":"JNF051120","confidence_band":"low","label":"How Things Work","score":0.6927,"source":"bisac_hint_model"},{"bisac_code":"JNF007090","confidence_band":"medium","label":"Science & Tech Biographies for Kids","score":0.6922,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"JNF006040","confidence_band":"high","label":"Art History for Kids","score":1,"source":"onix_publisher_code"},{"bisac_code":"JNF051130","confidence_band":"high","label":"Machines & Tools","score":1,"source":"onix_publisher_code"},{"bisac_code":"JNF061010","confidence_band":"high","label":"Inventions","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Inventions","score":0.7137,"slug":"inventions"},{"label":"How Things Work","score":0.6927,"slug":"how-things-work"},{"label":"Science & Tech Biographies for Kids","score":0.6922,"slug":"science-tech-biographies-for-kids"}],"reader_fit":["Good for readers interested in inventive art and creative problem-solving"],"related_lists":[],"series":null,"similar_books":[{"authors":["Micha Archer"],"book_id":"9780593616550","cover_image_url":"https://img.bookfrontier.com/9780593616550.jpg?v=af20ba99df54f513","score":0.7036,"title":"Wind Watchers","url":"https://bookfrontier.com/books/9780593616550"},{"authors":["Pat Hutchins"],"book_id":"9780689717444","cover_image_url":"https://img.bookfrontier.com/9780689717444.jpg?v=d42068821ea3d513","score":0.6669,"title":"The Wind Blew","url":"https://bookfrontier.com/books/9780689717444"},{"authors":["Paul Fleischman"],"book_id":"9780763627959","cover_image_url":"https://img.bookfrontier.com/9780763627959.jpg?v=a4436e70f4ccf18e","score":0.6256,"title":"Sidewalk Circus","url":"https://bookfrontier.com/books/9780763627959"},{"authors":["William Kamkwamba","Bryan Mealer"],"book_id":"9780147510426","cover_image_url":"https://img.bookfrontier.com/9780147510426.jpg?v=b3f2a35ba0e34455","score":0.6246,"title":"The Boy Who Harnessed the Wind","url":"https://bookfrontier.com/books/9780147510426"},{"authors":["Young Vo"],"book_id":"9781646144495","cover_image_url":"https://img.bookfrontier.com/9781646144495.jpg?v=8badebec3e6e30ed","score":0.6212,"title":"Makers","url":"https://bookfrontier.com/books/9781646144495"},{"authors":["Nikki McClure"],"book_id":"9781536216585","cover_image_url":"https://img.bookfrontier.com/9781536216585.jpg?v=586303f7dd0b7b7d","score":0.6202,"title":"Old Wood Boat","url":"https://bookfrontier.com/books/9781536216585"},{"authors":["Emily Lex"],"book_id":"9780736980395","cover_image_url":"https://img.bookfrontier.com/9780736980395.jpg?v=3fcd05ba7e9fb209","score":0.6177,"title":"Twirl","url":"https://bookfrontier.com/books/9780736980395"}],"topics":[{"evidence_refs":["keyword:children's books about wwii history"],"label":"History","score":0.4536,"slug":"history"},{"evidence_refs":["keyword:children's literature legacy award winner"],"label":"Children","score":0.2129,"slug":"children"},{"evidence_refs":["keyword:children's books about wwii history"],"label":"About","score":0.1333,"slug":"about"},{"evidence_refs":["keyword:children's literature legacy award winner"],"label":"Literature","score":0.057,"slug":"literature"},{"evidence_refs":["keyword:children's literature legacy award winner"],"label":"Award","score":0.0359,"slug":"award"}],"what_you_get":["Themes: Creative invention, Folk art, Resourcefulness.","Themes: History, Children, Literature.","Reading lane: Inventions and How Things Work."]},"llm_signals":{"confidence":0.91,"pacing":"unknown","reader_fit":["Readers interested in inventive art and creative problem-solving"],"themes":["Creative invention","Folk art","Resourcefulness"],"tropes":[]},"source_presence":{"amazon":true,"book_detail":true,"goodreads":true,"llm_signals":true,"similarity_seed":true},"stats":{"amazon_ratings_count":0,"goodreads_ratings_count":73,"goodreads_reviews_count":10,"quality_score":0.8593}}
