Scientific Methods

The scientific method seeks to explain the complexities of nature in a replicable way, and to use these explanations to construct useful predictions. It provides an objective method to find solutions to problems in a number of scientific and technological fields. Often scientists have a predilection for one outcome over another, and scientists are conscientious that it is vital that this preference does not bias their interpretation. A strict following of the scientific method attempts to minimize the pressure of a scientist's bias on the outcome of an experiment. This can be achieved by correct experimental design, and a thorough peer assessment of the experimental results as well as conclusions of a study.

Scientists use models to refer to a explanation or depiction of something, specifically one which can be used to construct predictions that can be tested by experiment or observation. A hypothesis is a disputation that has been neither well supported nor yet ruled out by experiment. A theory, in the context of science, is a logically self-consistent model or framework for recitation the behavior of certain natural phenomena. A theory typically describes the behavior of much broader sets of phenomena than a hypothesis — commonly, a large number of hypotheses may be logically bound together by a single theory. A physical law or law of nature is a scientific generalization based on a adequately large number of empirical observations that it is taken as fully verified.

People

People are a group of humans, either with not mentioned traits, or specific characteristics (e.g. the people of Spain or the people of the Plains).
The term people is often used in English as the suppletive plural of person. However, the word persons is sometimes used in place of people, particularly when it would be ambiguous with its collective sense (e.g. missing persons instead of missing people). The term people can together refer to all humans or it can be used to identify the citizens of a nation, or members of a tribe, ethnic, or religious group. People of color is a phrase used to describe people with skin color darker than that of white people.

Pollarding

Pollarding is a woodland management method of hopeful lateral branches by cutting off a tree stem or minor branches two metres or so above ground level. The tree is given a year to regrow, after the first cutting, but once begun, pollarding requires annual maintenance by pruning. This will ultimately result in somewhat expanded (or swollen) nodes topping the tree trunk with multiple new side and top shoots growing from it.A tree that has been pollarded is known as a pollard. A tree which has not been pollarded is called a maiden or maiden tree; which also refers to the fact that pollarding is usually first undertaken when the tree is quite young. Pollarding older trees typically result in the death of the tree. Pollarding is sometimes abused in attempts to curb the growth of older or taller trees. However, when performed properly it is useful in the practice of arboriculture for tree management.

Ice

Ice is the name given to any one of the 14 known solid phases of water. Though in non-scientific contexts, it usually describes ice Ih, which is the most abundant of these phases. It is a crystalline solid, which can appear transparent or an opaque bluish-white color depending on the presence of impurities such as air. The addition of other materials such as soil may further alter appearance. The most common phase transition to ice Ih occurs when liquid water is cooled below 0 °C (273.15 K, 32 °F) at standard atmospheric pressure. However, it can also deposit from a vapor with no intervening liquid phase such as in the formation of frost. Ice appears in varied forms such as hail, ice cubes, and glaciers. It plays an important role with many meteorological phenomena. The ice caps of the polar regions are of significance for the global climate and particularly the water cycle.

Kinetic power

Some watches are powered by the movement of the wearer of the watch. Kinetic powered quartz watches make use of the movement of the wearer's arm turning a rotating weight, which in turn, turns a creator to supply power. The concept is similar to that of self-winding spring movements, except that electrical power are generated instead of mechanical motion alone.

Jewelery division

Tanishq is currently the most prominent jeweler’s brand of India, and it pioneered the concept of branded jewelers and ornaments in India. The name Tanishq has been formed by combining "Ta" and "Nishk" or "Nishkh" .
Tanishq is India's largest jewelers brand with a wide range of jewelers in 22Kt pure gold studded with diamonds or coloured gems. It is the fastest growing jewelers brand in India. Tanishq, established in 1995, challenged the established family jewelers and introduced new rules in precious jewelers; a category as old as civilization. Tanishq challenged the age-old jeweler’s word with Tata's guaranteed purity. It exploded the market with facts about rampant impurity across India. It introduced technology-backed challenge in a category completely governed by individual trust. Tanishq introduced innovations like Karat meter, the only non destructive means to check the purity of gold; machine made jewelers, which offers superior finish and value to the customer and handcrafted jewelers which is influenced by various jewelers’ traditions of India.

Tanishq has set up production and sourcing bases with thorough research of the jewelers crafts of India. The 1, 35,000 sq. ft. factory is equipped with the latest and most modern machinery and equipment. The factory complies with all labour and environmental standards, located at Hosur, Tamil Nadu. The brand brings together the work of Kari gars, which specialize in different styles of making jewelers. Kari gars, who continue to be an exploited lot with other jewelers, are paid fair remuneration and work under good working conditions in Tanishq.
