Born with an innocent mind, my interest in Machinery and STEM (Science, Technology, Engineering, and Math) started primitively with my parents, or more specifically, the books that they bought and read for me in my childhood related to Navigation, Universe, Nature... in which books by Stephen Hawking like Universe in a Nutshell or Blackhole attracted me the most. That has raised my curiosity: Why does everything revolve around its particular orbits? When I grew up, I realized that I could find the answer by researching, studying, and performing well in natural subjects at primary, secondary, and high school levels.
