John Dalton used Intellectual deduction to develop the first universal atomic theory. While some of the theory has been corrected, most of the theory remains intact.
A scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact is typically referred to as the scientific method. This process involves systematic observation, experimentation, and the formulation of hypotheses, followed by analysis and interpretation of data. By conducting controlled experiments and making repeatable observations, scientists can validate or refute their hypotheses, contributing to the body of scientific knowledge. Ultimately, the goal is to ensure that findings are reliable and can be replicated by others in the field.
The definition of an experiment is a procedure that is done in order to make a discovery, test a hypothesis, or test a known fact. An experiment is often the testing of a scientific theory, although it can be applied to other fields as well, as long as it meets the criteria of the definition.

He made his dicovery 1815 about the Theory of Evolution
john Dalton invented the atomic theory. John Dalton introduced the basic concepts on which the modern periodic table is based.
that atoms can be broken
John Dalton was an English scientist in the eighteenth century. He developed atomic theory and published a table of atomic weights.
The discovery of electrons showed that atoms were not indivisible as Dalton had proposed, but instead contained subatomic particles. This led to a revision of Dalton's postulate that atoms were the smallest, indivisible particles, as it became clear that atoms could be divided into even smaller components such as electrons.

In addition to developing the atomic theory, John Dalton also made significant contributions to the understanding of color blindness, meteorology, and the study of gases. He proposed the law of multiple proportions, which laid the foundation for modern stoichiometry in chemistry. Dalton's work on the partial pressures of gases also led to the development of Dalton's Law of Partial Pressures.
The indivisible solid sphere model, also known as the billiard ball model of the atom, was proposed by John Dalton in the early 19th century. He suggested that atoms are indivisible spheres that make up all matter and that they combine in simple whole number ratios to form compounds.
John Dalton eventually went into partnership with his brother and in 1785 took over a different school in Kendal where the brothers offered a range of subjects including languages and 21 mathematics and science courses! Despite the school's popularity (they had 60 pupils at one point) the school did not make money and Dalton had to write answers to "ladies questions" in magazines to make needed extra income.
Dalton discovered the particles that make the atom and the atom itself
Amongst other things, John Dalton thought of matter as being made up of particles. His particle theory is sometimes referred to as the 'billiard ball model' since he thought of atoms as being indivisible, unlike what we know nowadays. He also worked on the chemical formulae of different substances.
John Dalton proposed that all matter is made up of tiny, indivisible particles called atoms, which combine in simple whole number ratios to form compounds. This laid the foundation for the development of atomic theory in chemistry.
John Dalton. N.B.: John Dalton [born: September 6, 1776; died: July 27, 1844, at age 67] was an English chemist and physicist who claimed matter was made up of tiny particles and that these particles were identical for any given kind of matter. Moreover, he claimed these particles were indivisible and could neither be created nor destroyed in any chemical process, only be altered in the manner they were grouped.
