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.

Time zones are the type of zones in which times are followed up differently in each zone; which means, that countries in each zone follow different times. For example, if we are in India where the time is 5:30 PM Friday then the time in London will be 12:00PM Friday . Even more interesting is that, if we are in India where the time is 9:30PM Thursday , and travelled along westwards to Abu Dhabi within 1 hour with a high-speed jet, then the time will be still at 9:30PM Thursday as before. So we have no loss of time. This is the magic of Time Zone! Time Zones of Earth There are roughly 24 time zones in the world corresponding to the 24hr in the world. But some countries make a quarter and a half an hour offset; due to which there are more than 24 time zones in the world. These time zones are determined by the longitudinal lines around the earth that are separated by 15° corresponding to ...
