This writing is based on one of my favourite books 1001 inventions:-salim al hasan I want to share what I learn here as I think it is important for not only me but people who know about this to share it and never forget it like they did in the past. It is important to spread about what happened in these ages as we don't learn these stuff in our text books I hope u share it and love it the real reson for the book 1001 inventions is to make people aware of how this civilization let to new inventions and how we still use it today in our daily life and to even inspire youngsters :)
