STATE VECTOR STATE OF THE UNIVERSE STATE IS SOMETIMES USED AS A SYNONYM FOR PHASE OF MATTER. IN CLASSICAL MECHANICS SYSTEM (OR BODY) REFERS TO ITS CONDITION AT PARTICULAR MOMENT TIME THUS THE TERMS INITIAL STATE REFERENCE ETC. THERMODYNAMICS/STATISTICAL MECHANICS THERMODYNAMIC OR MORE PRECISELY MACRO SPECIFICATION COMBINATION PHYSICAL PROPERTIES (E.G. TEMPERATURE VOLUME PRESSURE ETC). EXAMPLE AN EQUATION DESCRIBES RELATIONSHIP BETWEEN STATES SYSTEM. ON OTHER HAND SAME CONTEXT ABOVE MICROSTATE DETAILED DESCRIPTION COLLECTION ATOMS PARTICLES. THERE MAY BE MANY MICROSTATES CORRESPONDING MICROSTATE. STUDY DYNAMICAL SYSTEMS TYPICALLY MODELLED DIFFERENTIAL EQUATION. VARIABLE SUCH OFTEN CALLED SOME CASES THIS COINCIDES WITH SENSE IT ABSTRACT. QUANTUM VECTOR OBJECT CONTAINS INFORMATION ABOUT WAY THAT CURRENTLY IS. ? SPINLESS FREE PARTICLE MOVING LINE ALSO PARTICLE'S WAVEFUNCTION REPRESENTED BY $E^\{I(KX$ - \OMEGA T)}. FORMALISM LETTER T DENOTES TIME AND X POSITION TIME T. PARAMETERS K ? ARE RELATED SPEED MASS PARTICLE. THUS POSITION MASS SPEED GENERAL ONE CAN ALWAYS DESCRIBE MECHANICAL SYSTEM WHICH COULD CONSIST THAN PARTICLE VECTOR. SHOULD NOTED CONCEPT HAS LED CONFUSION PHYSICS EVIDENCED PARADOX KNOWN SCHRÖDINGER'S CAT. TERM POINT SINGLE INSTANT. SINCE UNIVERSE WHOLE CONSIDERED PARTICLES WE SPEAK UNIVERSE USING MEANING STATISTICAL PHYSICS. WORDS WHEN REFER REFERRING ENTIRE IS PUT STILL ANOTHER WAY WOULD UNIVERSE.
