Skin pigmentation

-
Skin pigmentation is just a coloration with the effect of melanin. Exactly, pigmentation happened in human body and skin with an expose of sun burn. There have another cause of skin pigmentation. Addison disease is one of the most common cause of skin pigmentation. In generally, pigmentation is a colouration of skin that exactly causes darker of the skin. The responsible constituent of skin darkening is melanin. when skin  produces melanin it appears as a dark color. The more the melanin level in skin the more darker the skin. Damaged skin produces more melanin.

Sun burn is a major cause of skin pigmentation. sunlight significantly damages skin cells. these damaged skin cells produces more melanin into skin.

Another disease condition that is called Vitiligo. Vitiligo is responsible of patches of skin.

Genetic condition and its impact on skin


Some genetic condition can impact on skin in severer range. Albinism is such kinds of genetic condition that significantly impacts on skin. Due to the effect of albinism skin get no color condition. Some of the time the condition of colour of skin is lighter than the normal color may defined as the albinism.

Hyperpigmentation
Hyperpigmentation is a condition that refferes as a dark spot of skin surrounded by the lighter skin. It is a result of over melanin condition in a specific part of skin. hyperpigmentation are found mostly in old age. Though, in any age people can suffer with hyperpigmentation.

In women, there have some common cause of hyperpigmentation. Pregnency is one of the most common cause of hyperpigmentation.

Black hole

Black hole is a region of spacetime that pocess such kinds of gravitational pole where nothing can escape from it, even particles and electromagnetic wave.  General theory of relativity by Albert Einstein can give an idea of creating black hole. According to  general theory of relativity sufficient amount of compact mass can form spacetime that leads to form black hole. Black hole may be in three types. Micro types, stellar massive and supermassive.  There consider of a boundary of a black hole, that is called event horizon. Event horizon is such kinds of boundary region of black hole from where no escape is possible. Black hole may be compared with the nature of black body, because like black body, black hole do not reflects light. Simply, it is said that what a things matter or light fall into black hole have no chance of return back.  In quantum field theorem it have that event horizon can emite a radiation which is called Hawking radiation . How black...

Mass energy transformation equation

Einstein's mass energy transformation equation Albert Einstein established an equation that explains the relationship between mass and energy. This equation also explains how matter transform into energy. It is also called mass energy transformation equation. Mathematically mass energy transformation equation is expressed as bellow, E = mc² From above equation the symbol E is denoted for energy, m is for mass and c is for speed of light. Matter and energy inter transformation Matter can transform into energy explained by Einstein's mass energy transformation equation. In opposite manner energy also can transform into matter. If it was impossible to transform energy into mass then it was impossible to form our existing universe. Think about Big Bang. The first nucleus of the universe was created after three minute of Big Bang. What was the initial state before the Big Bang? An analysis of big bang theory shows that after big bang a hot and dense energy state starte...

Attractive force

-
The force acting among the objects that tends to closer together is attractive force. The opposite concept of attractive force is repulsive force. Repulsive force tends the particle to go away as far as possible. within an electrostatic force there exist both attractive force and repulsive force. Centripetal force tends to electron to go to nucleus and centrifugal force tends electron far away from the nucleus. Within a magnet we find that opposite pole of magnet attract each other and same pole of magnet repulse each other. Same electric charge repulse each other and opposite electric charge attract each other.
