pg37 QUANTUM MECHANICS (part 1 of 5)

Brief description of quantum mechanics

Quantum mechanics is a strange aspect of matter most dramatic at very tiny scales, i.e. regions smaller than 0.00000001 cm.  It says all matter is governed by waves.  The probability of finding a particle at each position and time can be expressed by a curve (a packet wave).  That is, there is not a definite position and time (that is, there is an uncertainty) that the particle will be found.  The curve (packet wave) is composed of numerous mono waves.  The probability of finding a particle possessing each momentum (velocity) value and energy value is also expressed by a curve, i.e. there is not a definite value of momentum (velocity) and value of energy to be found for the particle either (that is, there is also an uncertainty).  Although the strange characteristics of quantum mechanics are manifested most dramatically at tiny scales, it applies to all sized of objects, even to astronomical scales.
