The novel tells the story of a professor with a memory span of 80 minutes and his housekeeper. Despite my initial doubts, the book beautifully portrays the development of an unusual yet heartwarming family dynamic. The emotions are conveyed through mathematical theorems, cooking, and random touching, creating a palpable sense of love and compassion. The story is a unique, elegant portrayal of the relationships between an elderly professor, his housekeeper, and her son. The professor's struggle with memory loss and the housekeeper's personal challenges are delicately intertwined with their shared love for mathematics. The book is a short yet intense read that offers a fresh perspective on the significance of mathematics in our lives.
