Did you only compare Newton to Einstein, or scientist in general? What are your thoughts about Nikola Tesla? Because he may be the greatest of all time. He invented so many things for which he didn't get any credit, unfortunately, because most of his ideas and inventions were either copied or stolen by other scientists... He even spoke 8 languages. However, discussing about who is the greatest is subjective and depends on personal preferences I guess. Nevertheless, Einstein is my favourite scientist because I am from Germany haha :D
Anyway, keep it up fam!
