Dear Sir, If you had met Franklin, the electrical scientist, you would have asked a few questions. I would have one more question along with your questions that is did he know that people will die by touching electricity? You mentioned three inventions electricity, mobile and internet. Every discovery in science is amazing. Science has made our lives easier. Especially medical science. Without science, we would have to fight with the wild animals of the forest like primitive people. Your writing about science is very beautiful. Good luck to you.
