For a while Vajpayee studied law, but midstream he chose to become a journalist. This choice was largely influenced by the fact that as a student he had been an activist in more...

Alternative Medicine is a kind of diagnostic technique and method of treatment whose theory develops from accepted medical methods. Alternative medicine is often treated as a substitute of conventional medical treatments. It includes treatments like Ayurveda, Homeopathy, Osteopathy, Unani, Acupuncture, Anthroposophic medicine, Chiropractic, Herbalism, Naturopathy, Yoga and Meditation, Hypnosis, and traditional Chinese and Tibetan medicine. When alternative medicine is used in combination with conventional medicine for treatment, it is known as complementary medicine. Alternative medicine is often opposed to evidence based medicine and encompasses therapies with a historical or cultural, rather than a scientific, basis. Alternative medicine practices are as diverse in their foundations as in thei methodologies, and they vary from country to country. Practices may incorporate or base themselves on traditional medicine, folk knowledge, spiritual beliefs, or newly conceived approaches to healing. The advantages of alternative medicine are that they are often safe, without side effects and effective. more...

I have many friends at school and I love to play with them. In my neighborhood also there are many children who are my friends. But although I value their friendship a lot, I have another friend who is the dearest of all. That friend is my library. I have built a little library of my own at home. Ever since I was born my parents have been collecting books for me. It began with books teaching the alphabet. Then came numbers. Gradually I had books with short stories. My mother used to read them to me at bed time. Now I have fairy tales, folk tales from different parts of the world, fun books, books on geography, science, history and literature, all of which are presented in the form of a story. I love books. On my holidays I pick up any book and get so engrossed in it more...

A Hobby That I Enjoy My favorite past time is to spend time at the computer, even at a tender age I like computer systems. To having a computer was a dream, an almost impossible dream. I had a friend named George at that time, we were in the same school, same grade and we had a very good relationship. At that time he had a computer system and we spend our free time playing games, printing greeting cards, banners, we also did our school home work. It was very nice and playful even then I yearned to own my own computer, so I could spend more time learning how to use the computer. But I liked to have my own computer so I can do my own printings and spend more time learning how to use the computer. One day my parents went for a trip without me because more...

Whether one is studying physics, chemistry or biology there are certain topics which always overlap. Statics and dynamics including projectile motion in physics sometimes overlap with mathematics. Kinetic theory of gases, nuclear and atomic physics and radioactivity ore common to physics and chemistry. But certain topics are also in different levels. Now genetics, structure of DNA, RNA, protein and their action will be common between chemistry and biology. These overlapping chapters hove one advantage. Students know that subjects cannot be put in water tight compartments. One should learn to have an overall picture of science. However, when the same topic is dealt with in two subjects with varying rigour, students are at a loss to know which one is correct. Certain portions are dealt in detail in chemistry and the calculations of the Bohr atom model is more important in physics. Now that even Nobel Prizes in Chemistry and Biology more...

While we are now familiar with the American text books and earlier English books, we were not so familiar with the methods of Russian books. If the English specking countries were cut off from Russian books because of the cold war, it was again thanks to the cold war that we started knowing about Russian work better. After an initial neglect due to underrating of other cultures, in 1 954, when Russia announced that they had also sent a heavy satellite and also could make fusion bomb, every single publication in Russia was made available in English translations by the United States department of commerce and of course atomic energy establishments. Every journal was also translated. The contact with the French culture was again very useful. Simplicity of presentation is the strength of the French. The method of calculating the ground state of the atom, given the electronic configuration is more...
