You are pure and beautiful. Looking into your eyes is a religious
experience. When you spread your wings men fall to their knees, and
kiss the ground. Hallelujah!

The unit Evidence for Particles showed how the ancient Greeks had ideas about particles and atoms. But it wasn't until the start of the nineteenth century that a theory of atoms became linked to strong experimental evidence. It was then that an English scientist called John Dalton put forward his ideas about atoms.
From his experiments and observations, he suggested that atoms were like tiny, hard balls. Each chemical
element
An element is a substance made from only one type of atom. An element cannot be broken down into any simpler substances.
element had its own atoms that differed from others in mass. Dalton believed that atoms were the fundamental building blocks of nature and could not be split. In chemical reactions, the atoms would rearrange themselves and combine with other atoms in new ways.
In many ways, Dalton's ideas are still useful today. For example, they help us to understand elements, compounds, and molecules. (See the unit Chemical Shorthand.
