Who was the first engineer? Imhotep, Archimedes, or Ismail al-Jazari? I am not sure. However, I can definitely say that until today, every one of them, wonderful engineers lived and made incredible contributions to science and technology. If it is described the science as a building, every engineer until today has put a big or a small brick in this build- ing. Step by step and systematically, modern science has emerged and continues to evolve.
