sun is a second, or even a later generation star as revealed by its chemical constitution. The first generation stars were originally of pure hydrogen which was transformed in their extremely hot interiors into different element ranging from helium. Some of these stars exploded in the course of their career, and scattered into space the elements synthesised in their deep interiors. These later found their way into new stars under formation-the second generation stars. One of them is our sun The earth in present form is about 5 billion years old. The most primitive forms of living organisms appeared on the earth perhaps 2 billion years ago, the first birds and mammals are about 200 million years old. Man appeared between 1-2 million years ago. Agriculture seems to be no more then 10,000 years old, and the first writing was invented some 6,000 years ago Science, as an important element in determining man's economic, cultural and spiritual 'climate' has been in operation for less than two centuries Man is now harnessing, under controlled conditions, a source of energy million times more powerful than chemical energy. Harnes ing nuclear energy demands deep insight and considerable progress in fundamental science, as distinct from empirical arts and crafts It seems that man is now truly entering the age of homo sapiens' when he can aspire to a citizen not only of the One World in the making, but a citizen of the universe And it is no mean universe We do not know whether the universe is finite or infinite, but progress in radio astronomy is likely to provide an answer to this question within the next few years The explored part of the universe is populated by some ten billion galaxies, and each galaxy contains some hundred billion stars A typical galaxy has a diameter of hundred-thousand light years; Inter-stellar gas makes one to ten per cent of its total mass. During recent years planetary systems other than belonging to our sun have been discovered. (It is easy to show that for a planet the maximum size (radius) cannot be larger than about that of Jupiter) It is almost certain that intelligent life is no monopoly of the earth. May be, at no distant date man succeed in linking himself to a 'cosmic telephone network'.
Science Stresses Cooperation
The real strength of science lies in its relentless, vigorous and fearless pursuit of truth Scientific laboratories which less than a hundred years ago were a curiosity and a rarity are now studded all over the globe (Science teaching in India first started in the Calcutta Hindu College (which later became the Presidency College) founded in 1817 under the leadership of Raja Rammohun Roy) Any discovery made anywhere soon becomes the common property of all The language of science is a common language, and its achievements the heritage of all-the only truly common heritage. The world of science is an open one, and this has not altered essentially despite certain it aberrations has suffered because of its close connection with the apparatus of
