Maglev trains are one of the greatest inventions in man-made history. These trains float over the track using magnetic power. The name Maglev is an abbreviation of Mag netic Lev itation. As there is no contact between the train and the track, these type of trains moves faster with minimum energy loss. These trains are also well known for their eco-friendly operation, as it does not use any petroleum products like petrol, diesel, etc. From the year 1902, magnetic levitation has begun to rule the world. In 1984, the first commercial maglev train was introduced in Birmingham, the UK, with levitation of 15mm and a track length of 600m. From the past to the present, there were several breakthroughs made in maglev technology. These breakthroughs were successfully implemented at present in three countries; namely China, South K...
A cell is the building block of a living thing. Every living thing is made up of tiny little cells. Especially humans have a very large amount of different types of cells like skin cells, muscle cells, sperm cells, egg cells and other cells. All these cells have the same basic parts like cell membrane, cytoplasm, endoplasmic reticulum, mitochondria, nuclear membrane, nucleus and more. Here the nucleus is considered as the main part of the cell. Inside the nucleus, there is a thread-like structure called chromatin which is made up of DNA (Deoxyribo Nucleic Acid) wounded around proteins called histones. These chromatins are essential for our life to sustain. The DNA in the nucleus decides the way our life should evolve. The DNA stores all the information about our body and the operations that need to be performed by each cell.

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...
