BMR means Brain-Machine-Ratio（🧠/🤖）. It's a philosophy about the co-evolution between machines and humans. Turing represents the Information Revolution, and we use purple as the main color which means breakthrough and imagination. The Brain-Machine-Ratio consists of brain and machine. For Turing, the brain is mainly embodied in poetic science. The machine is Turing's machine, including: 1) An infinitely long perforated paper bag, representing the calculation of 0 and 1; 2) A magnifying glass, representing a read-write probe and a table of control rules; 3) A state register labeled "State A". In this way, Turing's machine is able to simulate any operation performed by humans.
