 What is GMT?           Greenwich Mean Time is the yearly average of the time each day when the sun crosses the Prime Meridian at the Royal Observatory Greenwich. Solar time varies throughout the year, as the time interval between the sun crossing a set meridian line changes. GMT stands for Greenwich Mean Time, the local clock time at Greenwich. From 1884 until 1972, GMT was the international standard of civil time. though it has now been replaced by coordinated universal time (UTC), GMT is still the legal time in Britain in the winter, used by the Met Office, Royal Navy and BBC World service. Greenwich Mean Time is also the name of the time zone used by some countries in Africa and Western Europe, including in Iceland all year round. How did Greenwich Mean Time Begin ?       It wasn't until the invention of the Pendulum clock in the 1650s that it was possible to work out the relationship between mean (clock) time and solar time.   ...

           Soap is a sodium salt or potassium salt of long chain fatty  acids having cleansing action in water. They are used as cleansing agents to remove dirt, oil from the skin and clothes. Examples : sodium stearate, sodium oliate and sodium palmitate formed using stearic acid oleic acid and palmitic acid. Saponification method     Saponification is a process that produces soap, usually from fats and lye using aqueous sodium hydroxide solution. Soap in your skin Soap is alkaline, which irritates sensitive skin, which is normally acidic. Alkaline skin degrades quickly as protease enzymes are activated that destroy the skin proteins. It makes the skin dry. It affects the structure of the skin. It affects the good bacteria on your skin. It can cause allergic reactions . Soap forms scum when used with hard water (water that contains a high amount of calcium in solution). The scum stops the surfactant properties, so one tends to use more soap....

      Diwali generally falls somewhere in October or November and it is much grander in North India that it is in the South. October/November is also the time when the season is changing, and its a weird kind of weather. Its raining, its humid and its cold at nights. Its also the time of the year, when you can get sick easily.        Th e mixed weather of the season supports the growth and spread of bacteria and germs. An ignited oil lamp, the chemicals emitted from the flame kills germs from the atmosphere around it. And the effect is multiplied when you light hundreds of them. Do you see where I am getting at? (also, when there is a death in the house, there is a lamp kept burning for several days. It all makes sense now.)  The light of a diya also meddles with the magnetic field around, the electro-magnetic waves produced linger on your skin. They activate your blood cells, increases your immunity and makes you feel good.  That is why duri...

Dr.Radhakrishnan was nominated 16 times for the Noble Prize in Literature and nearly 11 times for Noble Peace Prize . The First book of Dr.Radhakrishnan was about the Philosophy of Rabindranath Tagore. He was appointed as a spalding Professor of Eastern Religions and Ethics at the University of Oxford . Oxford University started the Radhakrishnan Chevening Scholarships and the Radhakrishnan Memorial Award. He was elected as Chairman of UNISCO 's Executive board. At the age of 16 Sarvepalli Radhakrishnan married Sivakamu. For almost 51 years, Radhakrishnan and Sivakamu were blissfully married. Dr.Radhakrishnan students were so fond of him that he was taken to the Railway Station from the University in a flower decked carriage pulled by his students from University of Mysore . Dr.Radhakrishnan accepted only Rs.2500 out of Rs.10,000 salary and the Remaining amount was donated to the Prime Minister's National Relief Fund every month during his tenure as the President of India....

         Generally Vinayaka Chathurthi is celebrated during the month of August or September just before the setting of Northeast monsoon in October.         The dry summer would have made water sources porous and rivers might have been running shallowly. Thus the clay from the idols when suspended in water would form a colloid that would coagulate the pores and form a layer that has very fine pores.         Water would find it difficult to move towards gravity in such a condition and thus sort to lateral imbibitions. This would naturally lead to increase and rise in the ground water level on the setting up of the monsoon. Our ancestors approached everything with a scientific knowledge.           

                                RO (Reverse Osmosis) water filtration is one of the most popular and cost-effective water filtration method.   In simple terms, a reverse osmosis water filter works as water is forced across a semi-permeable membrane, leaving contaminants behind that are flushed down the drain. The clean drinking water collects in a holding tank. RO filtration method are as follows: A sediment filter to trap particles, including rust and calcium carbonate  A second sediment filter with smaller pores An activated carbon  filter to trap organic chemicals and chlorine, which will attack and degrade certain types of thin-film composite membrane. Optionally, an ultraviolet  lamp for sterilizing any microbes that may escape filtering by the reverse osmosis membrane. Optionally, a second carbon filter to capture tho...

What is Alcohol?           Ethanol is simply called as Alcohol. Its also referred as Ethyl alcohol or Grain alcohol - the Primary ingredient in alcoholic bevvies. Ethanol is a colorless liquid that is a byproduct of plant fermentation. Ethanol is formed when yeast ferments the sugar in plants.  The Maximum of Alcohol percentage in beverages is 70-95% (Vodka). What happens to Human body?          Alcohol is mainly a depressant, but it actually has stimulating effects when you first start drinking. It begins to do its work as earlier, it reaches your mouth, and its effects become more noticeable as the alcohol makes its way through your body.  Mouth : As soon as alcohol passes your lips, some of it gets into your bloodstream through the tiny blood vessels in your mouth and tongue. Stomach and Small Intestine : Up to 20% of the Alcohol you drink goes into your bloodstream through your stomach. The rest of it gets in your bl...
