Wikipedia Meaning and Definition on 'Matter'
Matter is a general term for the substance of which all physical objects consist. In practice however there is no single correct scientific meaning of "matter," as different fields use the term in different and sometimes incompatible ways.
For much of the history of the natural sciences people have contemplated the exact nature of matter. The idea that matter was built of discrete building blocks, the so-called particulate theory of matter, was first put forward by the Greek philosophers Leucippus (~490 BC) and Democritus (~470–380 BC).
Matter is commonly said to exist in four states (or phases): solid, liquid, gas and plasma. However, advances in experimental techniques have realized other phases, previously only theoretical constructs, such as Bose–Einstein condensates and fermionic condensates. A focus on an elementary-particle view of matter also leads to new phases of matter, such as the quark–gluon plasma.[See more about Matter at Dictionary 3.0 Encyclopedia]
