Periodic System Theory

Periodic System   The current Periodic System is based on the one which was proposed by Mendeleiev with the inherent corrections to Moseley’s law, as it is said, used as sort order atomic number. It […]

Rotation theory

Rotation   A Rotation is a circular movement of an object around a center (or point) of rotation. A three-dimensional object rotates always around an imaginary line called a rotation axis. A rotation of a […]

Matrices operations theory

Matrices additions and subtractions theory   The sum of two Matrices (Aij), (Bij) of the same dimension, is another matrix (Rij) of the same dimension and with generic term sij=aij+bij.   Therefore, to be able […]

Hydrogen Bond Theory

Hydrogen Bond   Many hydrogenated compounds have properties some abnormal that can be interpreted by assuming that amongst its molecules is formed a special type of link, characteristic of hydrogen atoms, called as Hydrogen Bond, […]

Oscillations theory

Oscillations   Oscillations are the repetitive variation, disturbance or fluctuation over the time measure about a central value or system. A particle oscillates periodically when it moves relative to its equilibrium position. Simple harmonic motion […]

Calculate the Inverse of a Matrix II

Inverse of a Matrix theory   Inverse of a Matrix Definition method. If the product between two matrices is the identity matrix, then we say that the matrices are “inverse”; because by multiplying them we […]

Statics theory

Statics   Statics is the branch of mechanics that studies the bodies in condition of balance submitted to the action of forces. Strength is the action that one has on something, either by pulling or […]

Theory about Scientific Notation

Scientific Notation   Scientific Notation helps us to express in an easier way those numerical quantities that are too large or, conversely, too small. It is also known as Exponential Notation and it can be […]

Covalent Bond theory

Covalent Bond   Covalent Bond (nonmetal-nonmetal):   There are many molecules whose formation can not be explained by the ionic bond, the simplest cases are molecules which are composed of identical atoms, such as H2, […]

Dynamics theory

Dynamics   Dynamics is the part of physics that describes the time evolution of a physical system in relation to the causes of changes in physical and/or movement state. Dynamics’ aim is to describe factors […]
