      Each degree is subdivided into 60 minutes. Each minute is composed of 60 seconds. Said differently, an arc-second represents the distance of latitude or longitude traversed on the earth's surface while traveling one second (1/3600th of a degree).

      I have read the quran and the bible after which I decided to remain an atheist. The freedom of relligion is the corner stone of all civilized religions. They were all created by people out of fear (largely fear of death). That's why people invented after life and heaven. I respect what you believe in, I trust you respect what I believe in.
