Chocolates are Good

Chocolates have been found good for health in moderation. They contain cocoa which is storehouse of thousands of chemicals which are good for human health. It contains organic chemicals called poly-phenols. These chemicals have been proven to reduce the bad LDL Cholesterol and boosts HDL Cholesterol. This is good for our heart and arteries. The benefits of these poly-phenols do not stop here. They are very active compounds and catch the free radicals which are very harmful to our body. Free radicals are atoms, compounds which have free unpaired electrons on them and are very reactive and can oxidize many… Read More »Chocolates are Good

Wholesome Rice!!

Rice is the staple diet of majority of world’s population. Asian people mostly eat rice with vegetables and lentils. Annapurna is the Hindu god of rice. Her name comes from the Sanskrit word for rice, “anna”. She is often depicted with a rice spoon in her hand. What is the rice? It’s white part is the carbohydrates: precursor of sugar of the energy. The colour of rice comes from its outer shell or ‘bran’ which holds much of its nutritional value. It’s the bran or the coating which contains minerals and other micronutrients. When rice is processed (milled) much of… Read More »Wholesome Rice!!

Elements necessary for humans

At present there are 118 elements listed in the periodic table. Some of these elements are commonly found on the earth in the form of ores. Some are radioactive and have very short half lives. Many such elements have been synthesized in the laboratory and live for a very short time. Human body like other things existing is made of compounds which are made from the elements. Out of these 118 only some elements are connected with the human body. Although elements as such don’t make up the body it is the combined form that is molecules constitute the human… Read More »Elements necessary for humans

1905: Annus Mirabilis of Albert Einstein 

Annus mirabilis is a Latin phrase that means “wonderful year”, “miraculous year” or “amazing year”. This term was originally used to refer to the year 1666, and today is used to refer to several years during which events of major importance are remembered. Albert Einstein singlehandedly added 1905 as another Annus Mirabilis. In this year, his creativity peaked and he made the revolutionary scientific discoveries. He was just 26 years old. During that year he did: { March: Proved that the light consists of photons thus proving the quantum nature of the light. May: Proved the existence of the atom. June: Special Theory… Read More »1905: Annus Mirabilis of Albert Einstein 

Why Gold has the colour it has??

Gold as everyone knows is a noble metal sought after by everyone. By being noble means it is resistant to chemical reactions like corrosion by air and water combination. The answer tothe question why it has the colour it has lies in electronic configuration of gold atoms.  Its electronic configuration is [Xe] 4f14 5d10 6s1 where Xe stands for Xenon. The outermost orbitals are 5d and 6s.  There is one electron in the outermost shell. In the geometric structure, atoms are arranged in a particular config And the lone electrons present the 6s orbitals are diffused in the lattice which… Read More »Why Gold has the colour it has??

First observation of merger of two neutron stars

Neutron stars are the remnants of explosions of supernovae. Neutron stars are most dense in the universe so these are quite small in size. For example the size of London. They are so dense that a spoonful of neutrons weighs as much as 100 000 Eiffel towers. It so happens that when two neutron stars approach each other, they turn faster and faster generating the gravitational waves by modifying the space-time around them. Ultimately they collide and fuse. After this the eject lots of matter. How such events in occuring in the universe are detected? Electromagnetic rays emitted during such… Read More »First observation of merger of two neutron stars

Oil and Gas

Although researchers all over the world are working on the technology to harness the alternate resources of energy like solar, wind, hydropower and nuclear energy, the conventional resources of oil, gas and coal are still the major resources of energy. These resources are fast declining since they are non renewable. Rapid industrialization and urbanization are responsible for this. In addition, these conventional resources add pollutants to the atmosphere. Presently the positon of energy producers is like this World’s Biggest Oil & Gas Companies (Production in millions barrels per day) SAUDI ARAMCO: 12 GAZPROM: 8.33. NATIONAL IRANIAN OIL: 6 EXXONMOBIL: 4.7… Read More »Oil and Gas
