Democritus apparently recognized a need to account for the fact that the disorderly motion of individual distinct atoms could produce an orderly cosmos in which atoms are not just randomly scattered, but cluster to form masses of distinct types.
Although there was speculation about sub-atomic structure in the 1800's after John Dalton introduced the atom idea on a solid scientific basis, it was not until 1897 and J. Democritus believed that the first principles of the universe are atoms and empty space, everything else is merely thought to exist. By putting the full or solid and the void ontologically on a par, the atomists were apparently denying the impossibility of void. The breadth of his knowledge and the impact of his thought on subsequent Greek science have many to regard him as the of the fifth pre-Christian century. Void, like the atoms, is infinite and eternal.
Some thought it was water, others air, but they were all left with the problem of how changes occurred. Because the word in Greek for indivisible is 'atomos', thistheory gave rise to the atom. To the bastard sort belong all the following: sight, hearing, smell, taste, touch. He devoted many of the later years of his life to researches into the properties of minerals and plants, although we have no record of any conclusions he may have drawn. Some types of matter are particularly solid because their atoms have hooks to attach to each other; some are oily because they are made of very fine, small atoms which can easily slip past each other. They also should write a very brief analysis of how the theories are alike and how they differ.
In middle school, students should have become familiar with the early theories of matter and how they led to the work of Lavoisier and the birth of modern chemistry. While there has been a revival of interest in his work by twentieth century scholars for his precise theory of atoms, he was respected by most of his contemporaries as well. Due to complex circumstances beyond the scope of this lesson, the Catholic Church accepted Aristotle's position and came to equate atomistic ideas with Godlessness.

During the last decades, scholars have started to re-examine the fragments of the lost works, which have led to important changes in our understanding of Aristotle's philosophy. While discussing the specific perspectives of each point, emphasize that modern science has proven the early Greeks to be incorrect about atoms having no inside voids Point 3, Rutherford or internal structure Point 4, Thomson. And again he says it is unchangeable, and in general he states in express terms the kind of universe it is; The causes of what now exists have no beginning, but from infinitely preceding time absolutely everything which was, is, and shall be, has been held down by necessity.

Much of the best evidence is that reported by Aristotle, who regarded him as an important rival in natural philosophy. What tools, if any, are they using? However, rather than being based on empirical proof, it originated from the observation that because everything eventually decays and is sometimes recreated, there must be some invisible building blocks of materials that never decay. Quite how this affects the account of perception is not clear, as the sources tells us little about how touch is thought to work.
Otherwise an atom would be subject to changes from outside and could disintegrate. What distinguished him from his contemporaries is the fact that he had visited many distant countries during his early life and shared ideas with scholars around the world, which might explain his rationalism, humanism, and love of freedom.
