         The moon is an outer celestial object which revolves around the earth. It revolves around the earth, on an average of once in every 27 days due to the Earth’s heavier gravitational pull. The moon generally has two sides in it, namely the near side and the Far side. The side which we see now on the moon is called the near side and the side we don’t ever see is called the far side of the moon. Credit (Near Side):  By Gregory H.

So we always happen to see the one side of the moon. This is because the rotation of the moon matches with the revolution of the moon. Here rotation means, an object is rotating itsel...

          Money creation is a method followed by banks, to introduce some money into the economy. This happens when there is a  shortage of money or when the economy is slowing down.  Money can be introduced into the economy either by printing it (by purchasing bonds) or by giving loans, out of the deposit, or thin air. On the before topic, we had discussed money creation through loans, issued by commercial banks to individuals, which you can access from the below article. https://sciencetopic03.blogspot.com/2021/11/how-money-creation-is-done-in-economy.html In this topic, we shall discuss the money creation process, which is done by purchasing bonds. The process of money creation through loans, which we learned on before topic is fine, till there is no huge demand for money. If there is any such situation as huge demand or very shortage of money, then the central bank steps into action, to print more money. Every country has one central ban...

     Money creation is a method followed by banks to introduce some money into the economy. This happens when there is a shortage of money or when the economy is slowing down. Money can be introduced into the economy by printing it (by purchasing bonds), and by giving loans out of the deposit or thin air. One of the most followed methods that generate huge amounts of money creation is by giving loans. Let’s take a look at it. LOANS Loans are one of the best methods of introducing money into the economy. It is generally created by commercial banks without introducing new money into the economy. One of the popular loan methods which create money is Fractional Reserve Banking. It is the type of Banking, in which a portion of the customer’s deposit is maintained as a reserve and the remaining is lent out as a loan. Let’s figure that out with an example. Let’s say a person deposits $100 in Bank A. Now this $100 does not sit simply in the person’s bank vault; rather only...

          A LASER is a type of device in which the light is produced in a narrow beam. The reason for this narrow beam is, that the light waves in the laser are parallel to each other, whereas in normal light the light waves are not parallel to each other. So all the light waves in a laser travel in one particular direction. Also, the laser is very coherent and monochromatic (one color) in nature. Different light sources and their nature of light       The abbreviation of LASER is  Light Amplification by Stimulated Emission of Radiation, which means that the light is produced by the increase in intensity; through the process of stimulated emission. As the light produced is in a narrow coherent manner, it won’t get distorted as much, over longer distances. So it is used for measuring longer distances, such as measuring the distance between the Earth and the Moon. There are generally different types...

        Television is the most wonderful invention in mankind's history. Over time, television had evolved drastically. The major attraction of the television is its display. The display is responsible for showing images to us in the form of light. There are many types of displays today, among which some displays are most attractive to people even today. Those displays are,  LCD (Liquid Crystal Display  LED (Light Emitting Diode) These displays are one of the types of display technology evolved. Let’s look at the construction and working principles of these displays.   LCD (Liquid Crystal Display):           The LCD is the basic model of every modern display on the market. As the name suggests, this type of display contains liquid crystals that are semisolid. This crystal is mainly responsible for displaying images on the display. Based on their molecular arrangements, there are three major types of crystals used in displ...

     Our body is an amazing factory. It performs all types of functions. These amazing functions are done by special parts of the body. One of the main parts that do the main function is the enzyme. An enzyme is nothing but a biological catalyst, having an irregular shape that speeds up the chemical reactions taking place in our body, such as in cellular respiration, breaking down the food products for producing energy. Even if the enzymes are not there in our body, chemical reactions would occur, but it may be slow. An enzyme does not require any energy to perform these activities. If one chemical reaction has been finished by an enzyme, the same enzyme can be reused for another chemical reaction. Every enzyme ends with a name called ase. The word before ase indicates what function they are doing. For example, an enzyme called Lactase converts the lactose present in the milk to small sugars like glucose and galactose.
