The 1936 How Alan Turing's 1936 Concept Launched Modern Computers 💻

In 1936, Alan Turing sketched a “machine” on paper that defined what a computer is. It reads and writes symbols on an infinite tape, step by step—proving what is computable, and what is not (halting problem). That single idea led to universal Turing machines, stored-program computers, and today’s software and AI. In this cinematic explainer, we cover: Context: Why Hilbert’s Entscheidungsproblem led to Turing’s breakthrough How it works: Tape, head, states, and universal simulation Limits: Halting problem and undecidability (in plain English) Impact: From theory to Bletchley Park workflows and modern CPUs Legacy: Why the Church–Turing thesis still guides AI and code 🎥 Part of Machine Mind Origins — stories of how ideas became intelligence.
