"Concrete Mathematics: A Foundation for Computer Science" by Graham, Knuth, and Patashnik is a seminal book that bridges pure and applied mathematics. It is essential for anyone involved in computer science, especially those interested in algorithm design, mathematical analysis, and problem-solving.
For data scientists, this book is valuable for building a strong mathematical foundation. It emphasizes discrete mathematics, combinatorics, and algorithms—all critical areas for understanding data structures, machine learning models, and optimization techniques. The rigorous approach to problem-solving and the emphasis on mathematical proofs teach data scientists to approach problems systematically and think critically about their models and solutions.
