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.
When it comes to the formulation of policies about higher education, structuring the system, financial assistance, grants and salary, the statutory body-University Grants Commission-is mentioned like a sacred cow worshipped as well as butchered in the streets. How far the UGC is autonomous is a common knowledge. It has become a post office, a government organization, disbursing petty grants, sanctioned by the Central Government, among universities or institutions with a number of tags attached to them depending upon the status of the recipient institutions, state, Central, autonomous or deemed universities. There is a perpetual complaint about the non-availability of funds. The administration should appreciate that the jumbo cabinet and expenditure on legislatures could be cut down to feed and educate a few villages. The teacher wants to be a ladder upon which students could climb and scale new heights.

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.
Fireworks light up the sky during celebrations; they give a wonderful show of color and shapes that fascinate the eyes and minds of many. The beauty of the display often leads many to wonder where the colors come from. The short answer is that they are the result of the burning of metals placed in these explosives. These metals are elements of the periodic table that burn at different temperatures and give off colors at their melting points.
6 to 12 Months: Your baby has much better control over arm and leg movement. By 9 to 10 months, your baby should be able to move around by some means- either pulling, crawling, or scooting. By 12 months they should be able to stand by themselves and many will even start walking. Educational toys including wooden blocks that baby can stack and knock down, throw, or bang together to make noise are good choices. By 12 months, educational wooden blocks can be used for early construction play to promote development of motor skills, cause and effect, sensory and visual stimulation. Educational toys like the Sensory Ball from Edushape, provides great stimulation with different textures. Once babies learn to sit up, they will enjoy rolling a ball and trying to catch it as you roll it back. Letting your baby chase the ball will encourage movement. Trying to figure out why a square block wont go through a round opening will help develop problem solving skills- though it may cause some frustration in the beginning. By the time your baby is 12 months, they will start to enjoy stacking activities, though they will need help in trying to get the right order. More interest in books will be noticeable now. Try to buy books that have pages with different textures and simple flaps. This will help to develop their sense of touch.
