Dear, you would have asked Newton as an engineer some questions. Nice to know you are an engineer as I am also an electrical engineer. I sometimes sit and think about every discovery scientists make. Science has a contribution to make in every field. Where science has brought us can be seen only by looking at the lives of people in the early ages and the lives of people today. In particular, medical science has discovered a vaccine to protect against the corona virus epidemic a few days ago. I am impressed by your writing about science. Good luck to you.
