Sir Isaac Newton

Dear Isaac Newton,

You have truly impressed me. Without the theory of gravity, we would
still be wondering why things fall and would not know about the force
pulling us toward the center of earth. Physics, engineering,
economics, statistics, and medicine would not be as developed without
the invention of calculus. My life would not be the same without the
discovery of the three laws of motion. Transportation would be
completely different and there would unsafe cars, airplanes, or
rockets. Thank you for your hard work!

Thanks,

Mackenzie
