I assume you mean Democritus. Democritus, c.460-c.370 BC, a Greek philosopher, developed and systematized classical atomism. The theory postulated a world made up of hard, uncuttable particles of matter moving through empty space.
He didn't have one. His only name was Democritis, which meant "chosen of the people".
DEMOCRITIS!
around 430 B.C.

Democritus (not democritis) was an Ancient Greek philosopher but was also regarded as a scientist. Democritus is considered by many as the "father of modern science".He traveled to many places throughout the world trying to quench his thirst of knowledge. He study in many fields but if your just looking for a one word answer, it'd probably be science.
This is believed to have originated with the Greek Philosopher Leucippus of Miletus and his student Democritis of Adbera in the 5th Century BC
Hisname was Democritus, and he came up with the word "atom," which is Greek for indivisible.
Democritus (Greek: Δημόκριτος, Dēmokritos, "chosen of the people") lived from ca. 460 BC to ca. 370 BC, so roughly it must have been about 400 BC, certainly not 250 BC as stated in other answers up till now.
Democritis is a philisopher who discovers the impossible structure in which he called the 'atom' from the word 'atomos' which means uncuttable or undivisible. An atom has two parts. A nucleus and a surrounding surrounding electron field. The Nucleus has two parts, protons and neutrons. Electrons have a negative charge and protons have a positive charge and a neutron has the approximate mass on a proton but carries no charge.
Dalton, who got the idea from Democritis. Dalton turned this idea into a scientific theory which was All elements are composed of indivisible particles called atoms, Atoms of all elements are different from one another, Atoms of elements can mix together in whole number ratios to form compunds, and Chemical reactions occur as a result of when atoms are separated, joined, or rearranged.
Democritus was a pupil of Luccipus, and perhaps according to both of them and certainly according to Democritus, the atom was the irreducibleminimal quantity of matter. The concept of the infinite divisibility of matter was flatly contradicted by the atomic theory, since within the interior of the atom there could be no physical parts or unoccupiedspace. Every atom was exactly like every other atom as a piece of corporeal stuff. But the atoms differed in shape, and since their contours showed an infinite variety and could be oriented in any direction and arranged in any order, the atoms could enter into countless combinations. In their solid interior there was no motion, while they themselves could move about in empty space. Thus, for the atomic theory, the physical universe had two basic ingredients: impenetrableatoms and penetrable space. For Democritus, space was infinite in extent, and the atoms were infinite in number.
Nobody "discovered" that the Sun was at the centre of the Solar system.Aristarchus of Samos, a greek philosopher and astronomer (310BC-230BC) first presented the theory that the Sun was at the centre of the solar system (heliocentrism) but his ideas were rejected in favour of the theories of Ptolemy and Aristotle that the Earth was at the centre (geocentrism).Copernicus (1473-1543) re-raised, developed and published the heliocentric theory in the 16th Century (nearly 1800 years after Aristarchus). It was a contentious issue, and the heliocentric theory was supported by Galileo (1564-1642) but he was persecuted (tried by the Roman Church's inquisition and found guilty of heresy) till he died.Aristarchus of Samos, a Greek astronomer and mathematician about 2400 years ago.
