Red displays come from Lithium, Rubidium and Strontium. These metals give different intensities in color and some even play other roles. Lithium and Rubidium are metals in group one of the periodic table. Lithium gives a medium red color and is most useful, for this purpose in its carbonate form. Rubidium on the other hand gives a deep red/ violet-red flame and is also used to oxidize the mixtures in these explosives; without oxidation, they will not burn properly. Strontium burns with an intense red but it also has the job of stabilizing the elements used to make the fireworks.
Students of various educational institutes go on strike, almost yearly, demanding withdrawal of excessive fee hike. The tuition fees make up only about 13 per cent of annual expenditure in the present university education. It is now a formidable industry and the aim is to make money. Poor students, however, intelligent they may be, cannot afford to join colleges, professional institutions or courses. They may join such courses by putting their families under heavy debt of banks or financial institutions. Even in the USA, tuition fees contribute to about 15 per cent of the total annual expenditure on higher education. Nehru said: If all is well with universities, it will be well with the nation. Whereas Rabindranath Tagore once compared educated classes in India to A second storey in an old building that was added in, but unfortunately the architect forgot to build a staircase between them.
Even after half-a-century of Indian Independence, the fate of education, educators and students has hardly improved. The apathy of the power that be, including a large section of society, has not changed when it comes to human resource development and education. Even now there are more than four crore educated unemployed.
