The term ‘history’ is derived from the Greek word ‘historia’ which means ‘information’ or ‘an enquiry designed to elicit truth’. It is just “man — his story” — the story of efforts to satisfy his craving for an orderly social life.

History has been defined by different scholars in different connotations. Though the words and languages used often are different in character, but, the implications are not so different fundamentally.

i. According to the earliest definition of Aristotle, “History is an account of the unchanging past.”

ii. According to Reniev, history can be termed as a study which is concerned with the human past.

iii. E. H. Carr gives a very beautiful definition of history. He says — history is an unending dialogue between the past and the present.

iv. Robinson thinks history could be used for overcoming the natural bewilderment of unfamiliar situation.

There is no universally agreed definition of history. It has been defined differently by different historians.

a) Burckhardt said, “History is the record of what one ages finds worthy of note in another.

b) Carlyle says, history is nothing but the bibliography of great men.

c) According to H. G. Wells, “Human history is in essence a history of ideas.”

d) Miller says, “The course of life is like a sea; men come and go, tides rise and fall, and that is all of history.”

e) Marc Bloch thinks that history is the science of men in time.

Some thinkers are of the view that “God manifested himself in history.”

1) According to Freud, “Historical records are a law of right and wrong.”

2) Jones thinks that history is a veritable mine of life experiences and the youth of today studies history.

3) Henry Johnson gives the view that history is a detailed account of the events that have taken place.

4) Pt. Nehru says, “History is the story of man’s struggle through the ages against nature and the elements; against wild beasts and the jungle and some of his own kind who have tried to keep him down and to exploit him for their own benefit.

5. Dr. Radhakrishnan says, “History is the memory of a nation or a race.”

6. The best definition which is scientific to a great extent, was given by Rapson. According to him, “History is a connected account of the course of events of progress of ideas.”



An LPN to RN bridge online degree program is an educational program that a licensed practical nurse can take to earn a higher degree in nursing. This degree qualifies the student nurse to take the National Council Licensure Examination (NCLEX). The NCLEX is a required examination that all nursing graduates must take and pass to become a licensed registered nurse in the US.

Is the move from LPN to RN a feasible career direction for you to take? Yes. There is a growing scarcity of registered nurses. One that a World Health Report- 2003 (WHO) acknowledged: “The most critical issue facing health care systems is the shortage of people who make them work”.

In the USA today, statistics show that there is a population on ratio of 773 nurses for around 100,000 patients (The Global Nursing Review Initiative-2005).

Clearly, there is a wealth of job opportunities for an LPN looking for career advancement as an RN in the health care industry. As an RN, you will gain better autonomy. You will also be in the best position to assume a leadership role and substantially increase their ability to earn.

Is there one particular LPN to RN bridge online nursing degree program that you should be looking to join? No – the one that works is a program you have designed for yourself.

As an active LPN, you will be juggling a fulltime job while studying. The first step then is to evaluate your personal circumstances and your career goals.

Ask yourself these questions:

How will you be able to devote sufficient time to learning, while functioning at work and participating in your family’s lives? Can you rely on your family’s support to take on or rotate some of these domestic tasks with you?

Second step – inform the human resources department about your career plans. Their assistance will help you several ways:



Rescheduling work shifts.



Recommendations and guidance on hospital supported programs, as many hospitals offer tuition reimbursements.



Assist you in securing a position in your workplace, for your clinical learning experiences. This is a requirement of both online and offline nursing programs.



Third step – do an engine search for the different schools. Check out their programs. Submit your accomplishments to the accredited schools and then compare which among these will give you the most credits to becoming an RN. Most virtual schools give 30 credits to licensed practical nurses.

Last step – Once you have selected the program to enroll in, use the school’s resources. Most schools will assign you a guidance counselor to assist you with the application process, identify financial aid resources, and help you create a schedule that suits your work and personal schedules. This will help you on your path to bridge the LPN to RN career path.



Waxing eloquently on the basic importance of Mathematics in human life, Roger Bacon (1214-1294), an English Franciscan friar, philosopher, scientist and scholar of the 13th century, once stated: “Neglect of mathematics works injury to all knowledge, since he who is ignorant of it cannot know the other sciences or the things of the world.” And the ingenuity of his statement is there before us to see, in this Internet era.

However, mathematics, in itself, has all the ingredients that make it a universal language shared by all human beings irrespective of culture, religion, or gender. Pi is always 3.14159 regardless of where we are. Similarly, the elemental mathematical processes (like addition, subtraction, etc.) never get changed due to a change in the location or for any other reason whatsoever. These all say about the close intertwining of mathematics in our daily life.

At a time when even a common man is being increasingly dependent upon the application of science and technology in the day-to-day activities of life, the role of mathematics has undoubtedly been redefined. Right from getting up in early hours of the day to the ringing of an alarm, to wait for the counts of whistles of the cooker, to exchange currency at a ticket outlet while availing a public conveyance, almost every next moment we do the simple calculations at the back of our mind. Of course, these are all done pretty unconsciously without a thought being spared for the use of mathematics on all such occasions.

Reading time on a watch, rounding a date on a calendar, checking up the mileage of your car, halting at the filling station, attending to a roll call at school, getting scores in the class exams, scoring in a game, betting on a horse race, preparing a recipe in the kitchen, – the list is just endless if one goes on to note down the situations when our computational skill, or more specifically, simple mathematics comes to play a role. It scares us to certain extent to think of a life without any knowledge of calculation or computation, or in other words mathematics. In many a case, lack of a formal education hardly affects gaining a relative mastery in these computational skills which are so essential in our daily life.

At a psychological level, exposure to mathematics helps in developing an analytic mind and assists in better organization of ideas and accurate expression of thoughts. At a more general level, far away from dealing with the higher mathematical concepts, the importance of mathematics for a common man is underpinned whenever he visits banks, shopping malls, railways, post offices, insurance companies, or deals with transport, business transactions, imports and exports, trade and commerce, and the ilk. Even when we think of role of mathematics in our recreational activities, we surprisingly have a list that runs quite long: video games, computer games, puzzles, riddles, and so on.

It ensues from the above discussion that a modern life style seems completely handicapped and at times, highly improbable, in the absence of mathematics. For, unless we are well versed in the language of numbers, we would find it difficult to reach at important decisions and perform everyday tasks. Be it to shop wisely, or buy the right insurance, or refashion a home within a budget, knowledge of mathematics holds the key, and hence, barely necessary.
