The Five Senses
Our body is an amazing creation. In this chapter, you'll discover some of its many abilities that qualify it as a machine you won't find anywhere else in the universe. For now, though, let's focus on the ways we interact with the world around us.
We have five senses: touch, taste, hearing, sight, and smell. Each of these senses allows us to understand the world in a different way and gives us a unique perspective on what we encounter each day.
Braille is a system of writing using raised bumps on a page that allows blind people to read. It was developed in 1829 by 20-year-old Louis Braille, a Frenchman who lost his sight at the age of three.
