BMR means Brain-Machine-Ratio(🧠/🤖). It's a philosophy about the co-evolution between machines and humans. Archimedes represents the Axial Age, and we use orange as the main color which means passion and knowledge. The Brain-Machine-Ratio consists of brain and machine. For Archimedes, the brain is mainly embodied in poetic science. The machine includes: 1) The symbol Pi (circumference rate) on the chest; 2) The lever and the earth in his left hand; 3) The screw pump in his right hand, representing simple machinery such as spirals, pulleys, and levers. Archimedes built the foundation for the later inventions of complex machines.
