 Gravity : Gravity is such a thing that any two object that possesses the object attracts one another.  It is not just a master limited but an energy gets attracted by gravity.  We will discuss about that energy later.  But before that, if you look around, there is gravity everywhere.  This means Gravity affects everywhere.  The biggest proof of gravity is that how we stand on earth is just from your feet and apart from this, if you look in the solar system, how the sun centers of the solar system and all planets on its side keep revolving.  Introduction : Ask anybody around you this simple question : "what is gravity ?" And what you did probably hear is "it's something that pulls objects towards the earth" or "it's a force exerted by the earth to pulls towards it". Now before I get to the basics of the gravitation, there is one thing I want to you understand well. Rather there's one thing I want to you forget ! Forget the fact that gravity has...

        A lot of people have noted that astronomy is a humbling enterprise to pursue. After all, every time we make a new discovery, we find ourselves further removed from importance. The Earth is but one planet among many, orbiting a sun that is one star among hundreds of billions, out in the suburbs of a galaxy that is one among hundreds of billions more. It's easy to feel pretty small when you see all that magnificence out there. And every astronomers keep making it worse ! Because now we know that what we can see isn't even everything there is. Normal matter, the stuff that makes up you and me and all we observe in the universe ? That's only a small fraction of what's actually out there. It's time we talk about some very very dark matters . What are dark matters?    In the 1960s and 1970s , astronomer Vera Rubin was observing spiral galaxies. She was interested in how they rotate, because you can learn a lot about a galaxy that way. Think about the sol...

 INTRODUCTION            Aromatic compounds are regarded as the class of organic compounds which resemble benzene in their chemical characteristics. Many of the aromatic compounds posses fragment odour 'aroma'  . In fact the term aromatic is somehow associated with chemical stability. The stable character of aromatic compound is attributed to the presence of a ring structure specific of benzene. All aromatic compounds generally contain one or more benzene rings in their molecules. As naphthalene, anthracene, etc. are also aromatic compounds, those are often called arenes and benzene and its derivatives are called Benzenoids . There are a number of cyclic compounds which do not contain a benzene ring but are still aromatic in nature. Such compounds are called non-benzenoids. Like the aliphatic compounds, aromatic compounds also include hydrocarbons, hydroxy compounds, aldehydes, ketones, acids etc.  Nomenclature of Aromatic compounds -: here ?...

Wave Optics -: Learning objectives   -: Electromagnetic waves, Plane waves.    -: Velocity of electromagnetic waves.    -: Properties of electromagnetic waves.    -: Hertz experiment.    -: Electromagnetic spectrum.    -: Huygen's wave theory, Huygen's principle, explanation of reflection and refraction.     -: Interference, Young's double slit experiment, Lloyd's single mirror, Fresnel's bi-prism experiment.  1. ELECTROMAGNETIC WAVES James Clerk Maxwell, one of the pioneers in the field of electromagnetic waves, gave his theory of electromagnetic waves in 1865. An electromagnetic wave is composed of oscillating electric and magnetic fields which oscillate in manually perpendicular planes. These two planes, besides being perpendicular to each other, are also perpendicular to the direction of propagation of the wave. Using his equations, called Maxwell's equations , he derived the formula for speed of electromagne...

-: HEALTH AND DISEASE Health can be defined as "a state of body when all the organs and organ systems are functioning properly in their physiology and a perfect balance is maintained between the environment and the body. " It can also be defined as, "a state of complete physical, mental and social well being" . So health is more than just absence of disease only.               Disease is the "sickness of the body and the mind" . It is the malfunctioning of the body due to some reasons. So disease can be defined as, "a condition of the body or its parts in which the functions are distributed or deranged" . -: WHAT CAUSES DISEASE ? The agent of a disease is a substance or a force which causes disease due to its excessive presence or absence. These agents can be of different types. 1. Biological Agents or Pathogens . Different microorganisms like bacteria, viruses, fungi, protozoans, helminths, etc. are called pathogens. 2. Nutrient Agents . The exc...

Hello friends                     Albert Einstein is a famous scientist who changed the way people see the World for a common man. Where did the principles of physics reach the human species today and You know, not only our species, but a single person, thinking of science, can reach from where to where. Simple thing if you know the rules of the game then you will play better than others. And let's be frank, All we have to do is mean that we can improve our life and the lives of people around us. And this is the story of my site ' Skss  ' to understand deeply this world and this life. Here I am a website Which has 3 parts in total like here 👇 (Albert Einstein Theory of relativity part-1,part-2, part-3) are updated soon, If you see it till the end, then you will have knowledge of your level As much as one Physics graduate of university. Lets start            So the story started in 1831, a royal society...

Chemical Energetics : Chemical energetics is a very useful thing for every student by itself. And sometimes it uses in our everyday life. So I have provided all notes about chemical energetics for everyone. REVIEW OF THERMODYNAMICS : 1. Thermodynamics . is defined as the branch of science which deals with changes in energy (usually heat) that accompany physical or chemical changes in matter. 2. Objectives of Thermodynamics .  (i) To predict the feasibility of a process (ii) To predict the extent of reaction (iii) To deduce certain laws of physical chemistry. 3. Limitations of Thermodynamics . (i) Law of thermodynamics apply only to matter in bulk and not to individual atoms or molecules  (ii) It predicts only the feasibility of process but not its success (iii) It doesn't predict the rate of reaction (iv) It doesn't tell anything about the mechanism of reaction. 4. System . is a part of universe selected for thermodynamic study. 5. Surroundings . is the part of the universe no...
