I Will Think of It

"I will think of it." It is easy to say this; but do you know what great things have come from thinking? We cannot see our thoughts, or hear, or taste, or feel them, and yet what mighty power they have! Sir Isaac Newton was seated in his garden on a summer's evening, when he saw an apple fall from a tree. He began to think, and, in trying to find out why the apple fell, discovered how the earth, sun, moon, and stars are kept in their places.

A boy named James Watt sat quietly by the fireside, watching the lid of the tea kettle as it moved up and down. He began to think; he wanted to find out why the steam in the kettle moved the heavy lid.
