Struck By Genius by Martin Padgett

After a violent head injury, a formerly unremarkable man awakens with extraordinary mathematical and visual abilities, perceiving complex geometric patterns and fractals in ordinary objects; the memoir follows his obsessive, self-taught journey to understand and formalize these perceptions with advanced math while exploring the neuroscience of acquired savant syndrome, the effects of trauma on identity, and the personal costs and transformations that accompany such an uncanny gift.
