Guru Purnima is a day to pay reverence to our teachers who lead us from darkness to light.
The place of Guru is very high in the Indian culture and mythology. And, they are filled with the famous legends wherein the pupils have gone to lengths to please or appease their mentors. We are also aware of Sandipani Rushi, Eklavya, Baiju Bawra and many other stories related to Guru Shishya.

Base Physical Quantities and their Units

There are two major systems of units used in the world: SI units (acronym for the French Le Système International d’Unités, also known as the metric system), and English units (also known as the imperial system).

English units were historically used in nations once ruled by the British Empire. Today, the United States is the only country that still uses English units extensively. Virtually every other country in the world now uses the metric system, which is the standard system agreed upon by scientists and mathematicians.

Some physical quantities are more than others. In physics, there are seven fundamental quantities that are measured in base or physical fundamental units: length, mass, time, electric current temperature, amount of substance, and luminous intensity.

Units for other physical quantities (such as force, speed, and electric charge) described by mathematically combining these seven base units.They are called units.

CLASSIFICATION OF MATTER

Matter is broadly divided into two - Mixtures and Substances



A material composed of two or more substances is a mixture.

In a mixture, the individual substances maintain their chemical identities.

Many mixtures are combinations of two or more substances, such as a mixture of sand and water. Such mixtures are called heterogeneous mixtures.

In some mixtures, the components are so intimately combined that they act like a single substance (even though they are not). Mixtures with a consistent composition throughout are called homogeneous mixtures (or solutions).



Any matter that has the same physical and chemical properties throughout the sample is called a substance. There are two types of substances - Element and Compounds

A substance that cannot be broken down into chemically simpler components is an Element.

A substance that can be broken down into chemically simpler components (because it has more than one element) is a Compound.

Number Systems

The natural (or counting) numbers are 1,2,3,4,5,1,2,3,4,5, etc. There are infinitely many natural numbers.

The whole numbers are the natural numbers together with 0 (zero).

The integers are the set of real numbers consisting of the natural numbers, their additive inverses and zero.

The rational numbers are those numbers which can be expressed as a ratio between two integers. For example, fractions.

An irrational number is a number that cannot be written as a ratio (or fraction). In decimal form, it never ends or repeats.
