John Napier

Hello. My name is John Napier. I lived a very, very long time ago, around the year 1550. I grew up in a big castle in a country called Scotland. My home was called Merchiston Tower. Even when I was a little boy, I loved playing with numbers. To me, numbers were like fun puzzles. I liked to spend my days figuring out how they worked together and solving problems with them.

As I got older, I saw that some math problems were very tricky. Multiplying big, big numbers together took a long, long time for people to do. I wanted to find a way to make it easier and faster for everyone. So, I came up with a big idea called logarithms. It was a special trick that turned hard multiplying problems into simple adding problems. Adding is much quicker. In the year 1617, I also made a fun tool to help with math. It was called 'Napier's Bones.' They were like special rulers that you could hold in your hands to help you solve math problems.

My ideas helped many people do their important jobs. Sailors on big ships used my number tricks to guide their way across the ocean. Scientists used them to make new discoveries about our world. I lived to be 67 years old and passed away in the year 1617. It makes me very happy to know that even today, my number tricks are still helping people learn new things and discover amazing ideas.
