In 2013, IBM scientists made history by creating A Boy and His Atom — the world’s smallest movie 🎥✨. They used a scanning tunneling microscope that magnifies over 100 million times to move carbon monoxide molecules one by one. In total, 65 atoms were arranged into shapes and patterns, frame by frame, forming a stop-motion film. Each frame was just 45x25 nanometers — so tiny that 1,000 frames could fit inside a single grain of salt 🧂. To pull this off, scientists worked at an ultra-cold tempera
