根据定义，“人才流失”，在学术上也被称为“人力资本外逃”是受过高等教育的大规模迁移，技术和人才的经济欠发达国家因冲突问题上高度富裕和发达国家、发展中国家的政治不稳定和缺乏机会。
全球范围内，知识分子的搬迁与人类一样古老。这种人才流失的术语起源于1960年，当时大多数知识分子如科学家和工程师都是真正的资产或任何国家的未来，从英国移居到了美国。
然而，随着科学技术领域的进步，只有知识分子和高素质的人才在高度发达的国家得到了非凡的授权。随着核心流的赤字，发达国家不得不依赖于土发公司的专业人才从发展中国家迁移到三个发达国家（美国，加拿大和英国）。

Introduction: 简介
According to a definition, 'Brain Drain', academically also known as the 'human capital flight' is the large scale migration of highly educated, skilled and talented people of less economically advanced countries to highly rich and developed countries of the world due to conflicted issues, political instability and lack of opportunities in the developing countries.

Globally, relocation of intellectuals is as old as mankind. This terminology of Brain Drain originated in 1960, when most of the intellectuals like scientists and engineers who were the real assets or the future of any country, emigrated from United Kingdom to America.

The unsolved issue of Brain Drain is happening all over the world for the sake of better working conditions including, the island nations of the Caribbean, the anterior colonies of Africa and mostly in federal economies like the Soviet Union previous Eastern Germany, where aptitudes were not monetarily salaried. This phenomena was not as severe till 1960's but with the huge capacity lopsidedly migrate to West Germany and North America from less developed regions.

Substantial exoduses of skilled people were apparent at altered epochs of the economic growth of the countries of Europe and North America. However, with the progress in science and technological fields, only the intellectuals and highly qualified brains was of extraordinary mandate in highly developed countries. With the deficit in the core stream, the developed countries had to be dependent on the LDC's. Professionals migrated from developing countries to three Developing countries (USA, Canada and United Kingdom) in 1960's and by 1970's, the figure had mounted.

This drift has continued in Africa and loss of huge qualified manpower is happen immigrations to Europe and North America annually. The questions that is arise in the social, political, economic, academic and probably in every sector of developing world. According to question the phenomena happened there are countless questions, but I want to explain the main attractions towards the developed world and why do talented and outstanding brains leave their countries? What are the costs of such migrations paid by developing countries? What policies can be implemented to stem such movements from LDCs to DCs?

The goal of this paper is to highlight the unsolved, conflicted issue of Brain Drain and the Scientific Diaspora and the cause and effect relationship in the global knowledge based societies and also to address the cancerous disease directing the developing countries to failure. I will highlight some major questions, giving some suggestions which help to make policies to fade the disparities and the exploitation of skilled and semi-skilled labour in the developed world who themselves benefited to create the legislative crime of Brain drain and to hijack the rights of Cos in the shape of Scientific diaspora communities.

How and when Brain Drain happens and intensifies
