Earth time and again known as the Earth, Terra, the World or Planet Earth is the third planet away from the Sun, and is the fifth biggest planet in the solar system. It is also the largest of its terrestrial system's global planets, making it the largest solid body in the solar system, and it is the only position in the universe recognized to humans to support life. It is as well the densest planet in the lunar system. The Earth was shaped around 4.57 billion years ago and its natural satellite, the Moon, was orbiting it soon thereafter, around 4.53 billion years ago.

The outer surface is divided into several tectonic plates that slowly travel across the surface over geologic time spans. The center of the planet remains active, with a thick layer of convicting yet solid layer and an iron core that generates a magnetic field. Its atmospheric conditions have been noticeably altered by the presence of life forms, which make an ecological balance that modifies the surface situation. Concerning 71% of the surface is covered in salt-water oceans, and the remaining contains continents and islands.

Short note on Music

Music is an art form that has prearranged sounds and quiet. It is articulated in terms of pitch (which contains melody and harmony), rhythm (which contains tempo and meter), and the quality of sound (which contains timbre, articulation, dynamics, and texture).

Music may as well absorb generative forms in time through the construction of patterns and combinations of natural stimuli principally sound. Music may perhaps be used for artistic or aesthetic, communicative, entertainment, traditional or religious purposes. The meaning of what constitutes music varies according to culture and social context, with various interpretations of the term being established under sub-genres of the art. Within "the arts", music can be classified as a performing art, a fine art, or an auditory art form

The history of music predates the written word and is tied to the improvement of each exclusive human culture. The development of music among humans occurred next to the backdrop of natural sounds like birdsong and the sounds other animals use to converse. primeval music, once more normally called ancient music, is the name given to all music created in preliterate cultures (prehistory), beginning somewhere in very late geological history.

Short note on Medical genetics

Medical genetics has the study and perceptive of human genetic diseases and syndromes. Physicians trained as geneticists are concerned in diagnosing the presence of genetic disorders, as well as providing hereditary counseling to people carrying deleterious mutations. Researchers working in medical genetics aim to make out the hereditary component of human diseases by finding and studying the involved genes and mutations.
