Dear, if you meet the scientist Robert Oppenheimer, ask him a question. He is a scientist who invented the atomic bomb. I agree with you, can he now imagine how many people are dying with bombs. You have illustrated with pictures how our transportation would be without science. The most amazing discovery is medical science. A few days ago, medical science created a surprise by discovering a vaccine to protect against the epidemic of corona virus. Medical science has made our lives a lot easier by discovering vaccines and antibiotic drugs during epidemics. Your writing about science is very beautiful. Good luck to you.
