         Benzene ( C6H6)  is the 'Queen of chemistry'. Benzene is an organic compound with the chemical formula of C6H6. It is also considered a parent compound of the various Aromatic compounds. The properties of benzene is a colorless, flammable, and highly aromatic liquid with a sweet odor. In benzene, there are two carbon atoms in each carbon atom and one hydrogen atom. The C-C bonds in benzene represent the combination of single and double bonds in resonance structures of benzene.   Benzene Chemical Formula is C6H6   Benzene Molecular Weight is 78u    Benzene is a versatile organic compound  applied in the various chemical industries such as in the manufacture of plastics, rubbers, lubricants, and more. However, Benzene is toxic and carcinogenic and that is why it has some non-industrial uses. Here are some applications of structure of Benzene: Benzene can be used as a solvent in nonpolar substances such as oils, fats, resins, ...

  Gastric acid ,  gastric juice , or  stomach acid  is a digestive fluid formed within the stomach lining . With a  pH  between 1 and 3, gastric acid  plays a key role in digestion of  proteins by activating  digestive enzymes , which together break down the long chain of amino acids  of proteins. The primary active component of gastric acid is Hydrochloric acid  ( HCl ), which is produced by  parietal cells in the gastric gland  in the stomach. The secretion is a complex and relatively energetically expensive process. Parietal cells contain an extensive secretory network (called canaliculi ) from which the "hydrochloric acid" is secreted into the  lumen of the stomach. The pH of gastric acid is 1.5 to 3.5 in the human stomach lumen , a level maintained by the proton    pump . A typical adult human stomach will secrete about 1.5 liters of gastric acid daily .  Gastric aci...

Dopamine:  Dopamine is a neurotransmitter produced by the hypothalamus, a small region of the brain that helps you feel pleasure. It’s an important part in your reward system, meaning the brain releases dopamine when you do things that feel good or pleasurable or when you complete a task. Dopamine also helps with movement and motivation.  Serotonin.  Serotonin is another neurotransmitter produced when you feel satisfaction or importance. It also helps regulate your sleep, appetite and mood. Many anti-depressant medications are selective serotonin reuptake inhibitors (SSRI) that help boost levels of serotonin.  Oxytocin.  Oxytocin is a hormone produced by the hypothalamus and released by the pituitary gland that produces feelings of love and connection. Also known as the cuddle hormone, the brain may produce oxytocin during sex or maternal behavior such as childbirth or breastfeeding.  Endorphins.  Endorphins are opioid peptides produced by the hyp...

 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....
