The Central and state governments invoke ESMA to curb the voice of agitating people, but it takes no time to give benefits to politicians and bureaucrats. It is essential to please them so that a symbiotic balance is maintained as also to oblige a few of them. The government has failed to take effective steps to curb industrialization of education. Within hours the doles given in Parliament and honorarium were doubled but the 6 per cent expenditure of the GDP on education has proved to be dogma persisting right from the Kothari Commission recommendations for over four decades now.
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.
How Babies Learn It is quite surprising the rate at which babies learn and develop. Learning begins in the womb and continues throughout childhood. In early life how a child learns centers largely around the relationship with the parents. At least until the child starts preschool, the job of stimulating and satisfying babys desire to learn falls primarily to the parents. While babies respond to their parents voice there are many other sounds they find interesting. When parents are choosing educational toys for babies they should look for toys that have sound, colors that are bright and contrasted like red, black and white, and have interesting textures that babies like to touch.
Some of the popular metals for fireworks include: Lithium, Rubidium, Strontium, Copper, Aluminium, Magnesium, Beryllium, Antimony, Titanium and many others. Burning these gives a wide variety of colors and makers of these products combine them based on the type of display they want. Below are specific examples of the different colors given by different elements.
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.
