Robert Hooke

The air is not an empty space, but a fluid body with many properties.

The pressure of the air is the cause of many phenomena that were previously mysterious.

The flame of a candle is a chemical laboratory in miniature.

The stars are not fixed in a solid sphere, but are scattered through an immense space.

The Earth is a planet like the others, and is subject to the same laws.

The human body is a machine of wonderful complexity and design.

The mind is the greatest instrument we have for understanding the world.

The pursuit of knowledge is the highest calling of humanity.
