Dear, if you meet Abbas Ibn Firnas and the Wright Brothers, ask a question. Find out how the idea of ​​making airplanes came about. Airplane making is a major contribution to science. We can travel from one country to another in a very short time. You wrote about three wonderful discoveries. Invention of electricity, mobile communication and aircraft. Science has made it easier for us in every field. Especially medical science has protected us for ages by discovering vaccines. If it were not for science, we would have to live like primitive people fighting. Your writing about science is very beautiful. Good luck to you.
