WELCOME IN THE WORLD OF UNDERSTANDING

Air it is not only a word but it is our lifeline without air we cannot survive for few minutes. Then question is arising that what is air? Air is nothing but the mixture of gaseous element in a definite proportion. Today air and wind is an important topic to discussion on it because we are live in the age of suicides age. Don’t be surprise because we are polluting the air and we also know that it is harmful for us so what you want to give the name of this organized event I give the name of this age is “suicide age”. Due to some other reason our earth fills heavy thunderstorm and high speed wind. So first we must know that what is wind? The flowing of air is called wind and when the air blow with high speed it become catastrophic for the live hood and ecosystem. Then question is arise that why wind flow? During daytime when the sand become more hotter than the water of the sea then the air above the sea become evaporate and the air of sea come to land to fulfill the blanks spa...

Atom bomb it is not only the bomb but it is another name disaster. Nuclear bomb is a too much dangerous for the health of the earth. our earth became ill by the various type of pollution but nuclear bomb is much more dangers then all type of pollution. As we all know that nuclear bomb used only 2 times in the world at first 6 august 1942 and 9 august 1942 on Japan and this catastrophic event were organized by America during second World War. Thousands of people die and many became handicapped during this blast. what you think about atom bomb do you know about the science of atom bomb? How it work and what process involved in nuclear energy ? To understand the nuclear bomb we must know about the atom. Atom is individual particles which are first discovered by Jhon Dalton. After the discovery of atom many of the scientists contributes his great efforts to explain the mystery of atom. The main contribution of J J Thomson who discover electron , Goldstein who discover proton , J...

You all are familiar with the wall of your home the bricks are used to build the wall or we can say that that the bricks are the smallest unit of the wall. Now when we talk about our living thing all living thing is made up of smallest unit called cell The combination of bricks change into wall and combination of cell change into body there are many latest research and experiment takes places daily in the scientific libratory stem cell is an example of it. Stem cell is found in human body which helps in synthesize the organ of the body. It is the great discovery in medical science with the help of stem cell we recover many disease we will learn about stem cell in detail Now at first we will discuss on feature is cell what are the organ involve in cell and what is the function of all in parts. The smallest unit of living thing is cell the combination of cell is called tissue combination of tissue is called organ combination of organ formed organ system and combination of or...

“ Y ou never count the money by closing your nose or it means air is most important for life” Climate change is an hotest topic of this present time. All the scientists of the world are worries about the climate change. The central theme of every research is how to stop the climate change and prevent the earth. The day to day observation of daily temperature, humidity, atmosphere, are called weather. Now we focus on climate. What is climate? The average observation of whether say 25 year is called climate. It is fixed for the place like when you here the name of Rajasthan and South Africa you can easily say that the climate of that place is hot. It means the climate is not the day to day observation but it is the average observation from decades. Now we all know about the weather and climate then the question is arise that on which factor the weather is depend? Temperature – It is the measurement of hotness and coldness of object when the sun ray come directly on e...

NO ONE IS BLACK ON THE EARTH AND NO ONE IS WHITE ACCORDING TO SCIENCE. AS WE ALL LEARN IN 10 CLASS THE THE OBJECT IS VISIBLE TO US IS DUE TO REFLECTION OF LIGHT THE COLOUR OF OBJECT WHICH WE LOOK ARE NOT THE REAL COLOUR OF THAT OBJECT BUT THE COLOUR OF LIGHT WHICH IS REFLECTED BACK FROM THE OBJECT TO THE EYE OF OBSERVER. NOW IT CLEAR THAT NO ONE IN THE UNIVERSE IS BLACK AND NO ONE IS WHITE. THE COLOUR OF OUR FACE IS DETERMINE BY THE REFLECTED RAY LIGHT....... 

Energy is fascinating human from millions of year. Fire is very important discovery in the history of mankind after the discovery of fire our life change dramatically. We daily listen about energy in our daily life. We take food to get energy then one question is arising that what is energy? Energy is nothing but a source which gives us capacity to do work. Some get energy from flesh or meat and someone get energy from green plant. But overall without energy we can’t do any work even breathing. Now come on point how energy creates and how energy lost. It is very interesting  to note that energy can neither be crated nor be destroy but it change one form to another. When we rub our hand the kinetic energy change into heat energy. bulb became hot befour glowing means heat energy change into light energy when heat energy come from sun it it used by solar panel to change heat energy to chemical energy and the battery convert chemical energy into electrical energy. Now it is ...

[Ashish kumar gupta] As we know that Electricity is the backbone of this modern society. Without Electricity we can’t awake in morning we can’t go ahead without electricity because it is leg and hand of the every people of the society. As we know that Electricity is come from energy and now day energy conservation is a global matter all country of the world is now worried on pollution and conventional source of energy. Now question is arise that What is electricity? How it can be produce ? What is electric shock ? Electricity is useful for us then why someone touch the electric wire get electric shock sometime people die in this chapter we will go through all this question and understand the basic concepts of electricity. As we all know about electron which is basic constituents of all atom and whole world is made up of atom so electron found in every matter of universe. Electron is also the basic cause o...

  [Ashish kumar gupta] As we know that electricity is the back bone of society we learn about electricity earlier now i give you 12 question after solving it we learn more about it in broader context  1.      Calculate the no. of electrons constituting 1C of charge. 2.      How much energy is given to each coulomb of charge passing through a 6V battery? 3.      Will current flow more easily through a thick wire or a thin wire of the same material when connected to the same source? Why ? 4.      How can three resistors of resistance 2 Ohm, 3 Ohm & 6 Ohm be connected to give a total resistance of a) 4 Ohm. b) 1 Ohm 5.      Two conducting wires of the same material and of equal length and diameters are first connected in series and then parallel in a circuit across the same potential difference. What is the ratio of heat produced in series and parall...
