Its true that all that we do is possible because of other people. Our math is based off of ancient mathematicians and who ever came up with the arabic numbering system. Our medicine is based off of the properties in herbs and has grown gradually from those early herbals. Our science is based off of people that decided to look and think in ways no one ever though of before such as a guy in a monastery growing pea plants or some crazy guy writing proofs about the movements of stars seen through glass.
I guess this makes me wonder if any of my contributions will help others and if my name will be mentioned in some dusty tome somewhere. Thinking of helping new generations discover new things that I can't even imagine just makes me want to work harder to help them and not letting anyone, both in the past and the future, down!
