Optical fibre : a  luminous discovery Science has given us many valuable and useful things, we know them as Inventions. Similarly, Optical fibre is also a scientific invention.......... We know about bulb , tube light. we take about bulbs we immediately remember that one name is Thomas Edison . This is an important and enlightening invention or discovery of everyones  life. But bulb can give you light up to a limited area. There was limit to the light........ But light has no limits this is what we see in optical fibre in physics. Let's start with basic information about optical fibre. In Marathi, it can be called as 'प्रकाशिय तंतु' ( light fibre.)   Descovery of optical fibre  It was discovered in 1952, Imperial College, London. The inventor of optical fibre is Narinder Singh Kapany  is Indian but had gone to Imperial College, London for higher education. He made glass string while doing his research work. The peculiarity of this glass string is that when a lamp was lit

Work, energy and power are the basic and important concept of Physics. In short physics is incomplete without the terms Work , Energy and Power. Work, Energy and Power are interconnected properties because in simple language Enargy means 'the ability to do Work.' We known about this concept from the 8th or 9th class.  Work, energy and power are the basic concepts of physics but this are very important and intrasting concept.  Work means effort, parform, function .... Energy means spirit, power. Energy ~ Work ~ Power  Energy is everywhere around us but we can't see this, only we can feel the energy in different forms.  Examples :- in kitchen for cooking food we use heat is nothing but one of the form of energy is known as heat energy. Similarly for car driving, jumping, in festival we use cracker , all have electricity in our home is also type of energy....etc  Energy is available in various forms or formats in the nature. First we start with the main domain of physics for

Vaccine and immunity power of our body. Currently were all talking about corona virus and there vaccine . Everyone is waiting for the corona vaccine. Scientists of all countries are working hard on this. Let's hope the vaccine against the corona virus is ready soon. Some peoples are first time familiar with the world VACCINE and some people hear the word vaccine but do not know the exact  meaning of Vaccine . But don't worry, In this article we cover some basics of vaccines and immunity. What is vaccine? History of vaccine. What is immunology? What is immunity power? Basic function of immune system. Working of vaccine.  Types of vaccine. Difference between vaccine and medicine. All about this are basic concepts of immunology.  It is important to know briefly what the basic functions of immune system, immunology and immune system are before we begin to understand what a vaccine is. Let's start with the point what is immunology? What is immunology ? "Immunology is th

* Bio-molecules *         "Bio-molecule are the life less molecules, which combined in specific manner to produce life and control biological reactions" In simple words, Bio-molecules are derived from reactions of simple molecules like Carbon, Oxygen, Hydrogen, Nitrogen.....Etc.          this bio-molecules are the chife constituents of our diet. This are most important to our metabolism . Carbohydrates are the major source of energy and protein play a variety of roles for proper functioning of living being .they are important components of hair, skin, muscles , nails ......Etc. all Enzymes are Protein which catalyze biological reactions. Important bio-molecules:- Carbohydrates. Lipids. Proteins. Nucleic acid. 1} Carbohydrates :-     "The compounds that can be hydrolyzed to polyhydroxy aldehydes or polyhydroxy ketones is called Carbohydrates." * Or *        " The optically active polyhydroxy aldehydes or polyhydroxy ketones is

🔬 BIOTECHNOLOGY 🔬 *Biotechnology :-       "The technology in which Biological entities are used to produce a product which beneficial for society."  In short,       "The Technological Application of Biology is known as Biotechnology ." *History of Biotechnology :- Earlier applications of Biotechnology,     Earlier ancient people used some micro-organisms for making beer and bread. 7000 years ago Mesopotamia people used bacteria to convert wine into vinegar. Ancient people use Yeast and some bacteria for making some products like beer, wine, bread,....etc useful food products are prepared by using bacteria. They don't know the mechanism behind this but general Ancient people trusting on the good product, taste and the quality of products.        Ancient peoples use medicine for relief from disease. They used Some medicine are directly occurred in nature. Ancient people used Honey   for respiratory infections and honey lotion for woun

COVID-19 The novel corona or COVID-19 today all world worry about this.  What you need to know about the Corona virus pandemic. What is Corona virus ? People know about Corona virus . the biggest health club and organization like WHO and etc. plays an important role by getting awareness program, scientists and researchers work on Corona virus for getting more information about structure, shape, genetic material and all this is important for making drugs against the corona virus. But at the time of present it's not possible. All countries are contributing to the fight against novel corona virus. Everyone knows how dangerous corona is !!!!! But the truth is something different .  So let's start with my question...... Is Corona really dangerous ???? Yes, is dangerous for human and sometimes animals. Today in the world almost 247 thousands peoples are death due to the corona virus and this chain continues. If you think from the other side...... Corona
