Bestselling author Daniel Tammet ( Thinking in Numbers ) is virtually unique among people who have severe autistic disorders in that he is capable of living a fully independent life and able to explain what is happening inside his head. He sees numbers as shapes, colors, and textures, and he can perform extraordinary calculations in his head. He can learn to speak new Languages fluently, from scratch, in a week. In 2004, he memorized and recited more than 22,000 digits of pi, setting a record. He has savant syndrome, an extremely rare condition that gives him the most unimaginable mental powers, much like those portrayed by Dustin Hoffman in the film Rain Man . Fascinating and inspiring, Born on a Blue Day explores what it’s like to be special and gives us an insight into what makes us all human—our minds.","forthcoming":false,"isbn13":"9781416549017","publication_date":"20071016","publisher":"Free Press","slug":"born-on-a-blue-day","subtitle":"Inside the Extraordinary Mind of an Autistic Savant","title":"Born on a Blue Day"},"discovery":{"categories":{"all":[{"bisac_code":"PSY022020","confidence_band":"medium","label":"Autism Spectrum","score":0.7536,"source":"bisac_hint_model"},{"bisac_code":"JNF053180","confidence_band":"medium","label":"Special Needs","score":0.7019,"source":"bisac_hint_model"},{"bisac_code":"YAN051230","confidence_band":"medium","label":"Special Needs for Teens","score":0.7005,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"PSY022020","confidence_band":"medium","label":"Autism Spectrum","score":0.7536,"source":"bisac_hint_model"},{"bisac_code":"JNF053180","confidence_band":"medium","label":"Special Needs","score":0.7019,"source":"bisac_hint_model"},{"bisac_code":"YAN051230","confidence_band":"medium","label":"Special Needs for Teens","score":0.7005,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"BIO026000","confidence_band":"high","label":"Personal Memoirs","score":1,"source":"onix_publisher_code"},{"bisac_code":"PSY008000","confidence_band":"high","label":"How We Think & Learn","score":1,"source":"onix_publisher_code"},{"bisac_code":"PSY022020","confidence_band":"high","label":"Autism Spectrum","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Autism Spectrum","score":0.7536,"slug":"autism-spectrum"},{"label":"Special Needs","score":0.7019,"slug":"special-needs"},{"label":"Special Needs for Teens","score":0.7005,"slug":"special-needs-for-teens"}],"reader_fit":["Good for readers interested in autism and neurodiversity","those curious about extraordinary mental abilities and savant syndrome"],"related_lists":[],"series":null,"similar_books":[{"authors":["Chloe Hayden","Chloé Hayden"],"book_id":"9781761500169","cover_image_url":"https://img.bookfrontier.com/9781761500169.jpg?v=20260424T163327Z%3A2026-04-24T16%3A33%3A27Z","score":23.5704,"title":"Different, Not Less","url":"https://bookfrontier.com/books/9781761500169"},{"authors":["Emily Katy"],"book_id":"9781800961418","cover_image_url":"https://img.bookfrontier.com/9781800961418.jpg?v=20260424T163327Z%3A2026-04-24T16%3A33%3A27Z","score":21.9826,"title":"Girl Unmasked","url":"https://bookfrontier.com/books/9781800961418"},{"authors":["Michael McCreary"],"book_id":"9781773212579","cover_image_url":"https://img.bookfrontier.com/9781773212579.jpg?v=20260424T163327Z%3A2026-04-24T16%3A33%3A27Z","score":19.9724,"title":"Funny, You Don't Look Autistic","url":"https://bookfrontier.com/books/9781773212579"},{"authors":["Erin Ekins"],"book_id":"9781787751712","cover_image_url":"https://img.bookfrontier.com/9781787751712.jpg?v=20260424T163327Z%3A2026-04-24T16%3A33%3A27Z","score":17.4011,"title":"Queerly Autistic","url":"https://bookfrontier.com/books/9781787751712"}],"topics":[{"evidence_refs":["keyword:autism, genius, geniuses, extraordinary minds, science, biology, daniel tammet, high-functioning, autistic, savant, aspe"],"label":"Science","score":0.3316,"slug":"science"},{"evidence_refs":["phrase_map_match"],"label":"Book Club","score":0.2086,"slug":"book-club"},{"evidence_refs":["keyword:autism, genius, geniuses, extraordinary minds, science, biology, daniel tammet, high-functioning, autistic, savant, aspe"],"label":"Biology","score":0.0682,"slug":"biology"},{"evidence_refs":["keyword:autism, genius, geniuses, extraordinary minds, science, biology, daniel tammet, high-functioning, autistic, savant, aspe"],"label":"High","score":0.0602,"slug":"high"}],"what_you_get":["Themes: autism, savant syndrome, human mind.","Pacing: reflective, voice-and-character forward.","Themes: Science, Book Club, Biology."]},"llm_signals":{"confidence":0.9,"pacing":"reflective","reader_fit":["readers interested in autism and neurodiversity","those curious about extraordinary mental abilities and savant syndrome"],"themes":["autism","savant syndrome","human mind"],"tropes":[]},"source_presence":{"amazon":true,"book_detail":true,"goodreads":true,"llm_signals":true,"similarity_seed":true},"stats":{"amazon_ratings_count":0,"goodreads_ratings_count":24294,"goodreads_reviews_count":2348,"quality_score":0.9669}}
