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.
Teaching profession is devalued in the country because the teachers cant compete in our society, have no muscle power, are educated and hence behave differently. Neither do they have guts of creamy bureaucrats nor institutional support of any kind. A teacher can entertain you with a pale smile on hearing that this is the profession of nation builders, the cream of society and a noble profession. The next moment teacher will be branded as cancers in societal marrow, getting salary for no work, craving for power, equality in salary and status with the Class A government servants. The teacher was the consultant and conscience keeper of society till mid-century. One could identify him by his tattered clothes, emaciated pale face, soft voice and meek behavior. He was the guru. That guru, comparatively having a better outfit now, has metamorphosed to a present teacher.
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.
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.
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.
