John Dalton

I am a poor hand at speaking, but I can make myself understood.

I have been much indebted to the kind assistance of my friends in the prosecution of my inquiries.

The atomic theory is the foundation of all true chemistry.

I have always been more desirous of discovering truth than of acquiring fame.

The ultimate particles of all bodies are atoms, which are indivisible and indestructible.

The combination of atoms takes place in simple numerical ratios.

Different elements have different types of atoms.

Atoms of the same element are identical in mass and properties.

Chemical reactions involve the rearrangement of atoms.

I am not a man of many words, but I hope my work speaks for itself.

The study of nature is the study of God's works.

I have always endeavoured to be accurate in my experiments and observations.

The atomic theory has opened up a new era in chemistry.

I have always been a lover of truth and simplicity.

The laws of chemical combination are as immutable as the laws of the universe.

My object has been to lay a foundation for the science of chemistry.

I have endeavoured to make my work as clear and intelligible as possible.

The atomic theory is not a mere hypothesis, but a system founded on facts.

I have always been more concerned with the advancement of knowledge than with personal gain.

The ultimate particles of bodies are of different sizes and weights.
