Hey friends, Today we learn about another interesting topic about revolving of the earth around sun and spinning around it's own axis. From primary class to higher class we learn that earth revolving around the sun. And spinning around own axis which cause to happening day and night. But you ever thinking why its happen?    In this article we trying to find out the answer of following questions. Why the Earth (or planets) moves around the sun? Is the sun really positioned in the center of solar system? Why the Earth spinning around own axis? When till the Earth spinning? W hy the Earth (or planets) moves around the sun?    Every object in the space is moving continuously with relative to its nearest heavier mass object. Earth is also moves around the sun. There are two famous theories behind this. rotation of earth around the sun *  First according to Isaac Newton the Earth moves around the sun because the higher gravitational force act on it. The sun is a hea

Hey friends,     Today we learn about an other interesting topic, is about 'Glass'. We can see the many things around of us that made from glass like window, bulbs, TV screen etc. Did you ever think about it how to form glass or why the glass is transparent.    In this topic we understand facts about the glass and finding the answer of following questions :- * What is Glass ? * How to form Glass ? * Why Glass is transparent ? and * Is Glass solid or liquid ? What is Glass ? :-    Generally glass is a rigid transparent material that often use widespread practical, technological, and decoration. water glass credits : pixel How to form Glass ?    Formation of glass is an interesting phenomena. Glass can formed by melting of ' Sand ' with ' Soda ash ' (Sodium Carbonate) and ' Limestone ' (Calcium Carbonate) at extremely high temperature approx 1700°C . Glass can be obtains by only heating the sand at high temperature more then 2000°C so ad
