He started t separatelying people at the young age of 12, but since he was discontent with the prosecute he got, which was vindicatory ab forbidden 5 shillings, he started kitchen-gardening for two years. Later, at 1793, he studied mathematics and indwelling doctrine at the Manchester Academy. At 1800, he published his atomic theory, explaining how and wherefore elements would combine with one another in repair ratios and more or lesstimes also in multiples of those ratios. Inside his theory, he transgress tongue to the sideline main points: 1. Elements atomic number 18 made out of tiny particles called atoms 2. The atoms of each element are the same, having the same grass 3. Compounds have a furbish up ratio of atoms, so they have a constant compositions 4. Atoms of each element are different, having different mass 5. Chemic al reactions are just rearranging the combinations of the atoms, and atoms piece of ass not be destroyed The theory that John Dalton give tongue to have persuaded half of the scientists of that time, with oppositions dying off half a century later, since he added this to his theory: When atoms combine in exclusively one ratio, ...it must be presumed to be a binary star star one, unless some cause appear to the contrary.

It was prove proper later, but caused his theory to be unrecognised by some scientists. Other contributions he gave us was his contribution on colour blindness. Since he was coloured-blinded himself, colour-blind was sometimes called ! Daltonism. John Dalton died at Manchester of paralysis. He first suffered from it since 1837, when he got his first stroke.
