USES OF VECTORS IN REAL LIFE

I always wonder how vectors are used in real life.Vectors and decomposition of vectors,dot and cross products are taught in the early stage in every undergraduate physics course and in every university.My question is how and where are vectors used? Do physicists really use vectors in every day life? If so where?

What Is a Vector?

By Steven Holzner from Physics I For Dummies, 2nd Edition

In physics, when you have a vector, you have to keep in mind two quantities: its direction and its magnitude. Quantities that have only a magnitude are called scalars. If you give a scalar magnitude a direction, you create a vector.

Visually, you see vectors drawn as arrows, which is perfect because an arrow has both a clear direction and a clear magnitude (the length of the arrow). Take a look at the following figure. The arrow represents a vector that starts at the arrow’s foot (also called the tail) and ends at the head.

EDUCATION - MEANING AND DEFINITION

Notes on the true Meaning, Definition and Concept of Education:
Meaning:

According to some learned people, the word "Education" has been derived from the Latin term "Educatum" which means the act of teaching or training. A group of educationists say that it has come from another Latin word "Educare" which means "to bring up" or "to raise".

According to a few others, the word "Education" has originated from another Latin term "Educere" which means "to lead forth" or "to come out". All these meanings indicate that education seeks to nourish the good qualities in man and draw out the best in every individual. Education seeks to develop the innate inner capacities of man.

By educating an individual we attempt to give him some desirable knowledge, understanding, skills, interests, attitudes and critical 'thinking. That is, he acquires knowledge of history, geography, arithmetic, languages and sciences.

He develops some understanding about the deeper things in life, the complex human relations, and the cause and effect relationship and so on. He gets some skills in writing, speaking, calculating, drawing, operating some equipment etc. He develops some interests in and attitudes towards social work, democratic living, co-operative management and so on.

As an individual in the society, he has to think critically about various issues in life and take decisions about them being free from bias and prejudices, superstitions and blind beliefs. Thus, he has to learn all these qualities of head, hand and heart through the process of education.
