The poem consists of six untitled books, in dactylic hexameter.The first three books provide a fundamental account of being and nothingness, matter and space, the atoms and their movement, the infinity of the universe both as regards time and space, the regularity of reproduction (no prodigies, everything in its proper habitat), the nature of mind (animus, directing thought) and spirit (anima ...

Philosophy of matter is the branch of philosophy concerned with issues surrounding the ontology, epistemology and character of matter and the material world. The word matter is derived from the Latin word materia , meaning "wood", or “timber”, in the sense "material", as distinct from "mind" or "form". [ 1 ]
The atomists agreed that motion required a void, but simply rejected the argument of Parmenides on the grounds that motion was an observable fact. Therefore, they asserted, there must be a void. Democritus held that originally the universe was composed of nothing but tiny atoms churning in chaos, until they collided together to form larger ...
Atoms and molecules had long been theorized as the constituents of matter, and Albert Einstein published a paper in 1905 that explained how the motion that Scottish botanist Robert Brown had observed was a result of the pollen being moved by individual water molecules, making one of his first contributions to science.
Motion (also path or trajectory) is a function r : Δ → R 3 that maps a point in the interval Δ from the time axis to a position (radius vector) in R 3. The above four concepts are the "well-known" objects mentioned by Isaac Newton in his Principia: I do not define time, space, place and motion, as being well known to all. [13]
The elements of earth, water, air and fire were derived of a combination of two of the characteristics of hot, wet, cold, and dry, and all had their inevitable place and motion. The motion of these elements begins with earth being the closest to "the Earth," then water, air, fire, and finally Aether.
Fully 70% of the matter density in the universe appears to be in the form of dark energy. Twenty-six percent is dark matter. Only 4% is ordinary matter. So less than 1 part in 20 is made out of matter we have observed experimentally or described in the standard model of particle physics. Of the other 96%, apart from the properties just ...
