Atoms are the smallest units of matter which are independent and have a definite address. Atoms of different elements are different in many aspects but size and atomic weight are the main attributes. I think there is no such thing as color of things. Color exists only when there is light. When the darkness falls, the color of things begins to dissolve and black color takes over everything. Black color thus obliterate all the differences due to colors. May be this is the reason why in Hindu mythology many Gods are dark complexioned. Take for example Rama, Krishna and Draupadi,… Read More »What Color are the Atoms?
There was a time when things started rolling on with advent of photosynthesis by cyano-bacteria or green algae which began preparing its food from carbon dioxide and water which were the only substances available in plenty. They paved the way for introduction of oxygen into the atmosphere and for beginning of life dependent on oxygen. In fact, both the products made by photosynthesis namely sugar and oxygen are used by animals including humans for sustaining their life. We animals are thus the species who learned to make use of the leg work of others to our own advantage. Of course,… Read More »Stomatal Index and Level of Carbondioxide in Atmosphere
In the beginning there was carbon dioxide, water and sunlight on our Earth and its environment. The same carbon dioxide which is the end product of today’s industrial processes. The factories spew carbon dioxide. Scientists are finding ways to fix this carbon dioxide which is the major cause of greenhouse effect and results in trapping the heat and disallows it dissipate and result in Global warming. Whereas in the present climate living beings mostly use oxygen to breakup the food and convert it to glucose and energy, in the beginning only organism that thrived on carbon dioxide was called green… Read More »Algae: A machine to make energy
Hinduism is very difficult to define. It cannot be confined to strict rules and regulations. It can be amended to suit certain needs. So it is a dynamic system. It is continually evolving. One of the beautiful feature of the system is that both animate and inanimate things are given equal status and thought to be the extension of the supreme one. The tenet that energy is the supreme cosmic entity has been proved to be true in the scientific experiments. Einstein’s famous equation states it in beautiful short equation which tells us the energy and matter are interconvertible. Thus… Read More »All is Energy
Plants are very smart, efficient and unforgiving in the energy management. Unlike the animals, who cannot regrow their limbs, plants see to it that inefficient leaves are cast off and replaced by new efficient one’s so that the food making machine continue to run smoothly. The leaves make the food by combining carbon dioxide and water in the presence of chlorophyll which shepherds the energy from sun and store it in the plant. Animals make use of this energy by eating the plant parts. This pigment imparts green color to the leaves and masks the faint colors of other chemicals… Read More »Plants are very Smart Indeed
Sugar has become a dreaded word in the modern world. The term is used for the diabetes disease which is acquiring the epidemic proportions in the world. Although sugar alone cannot be blamed for this disease. Sugar is the major energy source along with fats on which our bodies run. Even the carbohydrates which we take in the form of bread and rice are ultimately broken down to simpler sucrose and then glucose compounds and are assimilated by our bodies. It is a matter of living style like stressful life, overeating and sedentary habits. So let us not blame sugar… Read More »Sugarcane
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
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!!
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
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 of… Read More »1905: Annus Mirabilis of Albert Einstein
