Deen our duniya

abbaas ibn firanaas, ek pratibhaashaalee injeeniyar aur aavishkaarak, ne apane samay se sadiyon pahale apanee abhootapoorv rachanaon se itihaas par ek amit chhaap chhodee. unakee ullekhaneey upalabdhiyon mein 875 ee. mein kordoba, spen mein duniya kee pahalee saphal udaan masheen ka nirmaan shaamil tha.

adviteey saralata ka pradarshan karate hue, unhonne pakshiyon kee krpa ka anukaran karane ke lie halke reshamee kapade aur eegal pankhon se saje baans ke phrem ke saath udane vaale upakaran ka nirmaan kiya. ibn firanaas ke aavishkaar ne jo baat alag kee, vah thee niyantraneey pankhon kee isakee abhootapoorv visheshata, jo udaan ke dauraan gatisheelata kee anumati detee hai - liyonaardo da vinchee ke dijainon se pahale ka ek navaachaar.

apanee udaan masheen kee kshamataon ka saahasik pradarshan karate hue, ibn firanaas ne vishaal oonchaee se apanee aitihaasik udaan dekhane ke lie badee sankhya mein darshakon ko aakarsh*t kiya. das romaanchak minaton tak, vah aakaash mein udata raha aur apanee udaan kee mahaarat se darshakon ko mantramugdh kar deta raha.

haalaanki, unakee lainding, ek mahatvapoorn dijain nireekshan ke kaaran kharaab ho gaee, jisake parinaamasvaroop ek bhayaanak durghatana huee jisase unhen gambheer choten aaeen. apane anubhav par vichaar karate hue, ibn firanaas ne chikanee lainding kee suvidha ke lie ek poonchh tantr ko shaamil karane kee aavashyakata par dhyaan diya - jo ki bhavishy ke evietars aur aavishkaarakon ke lie ek amooly antardrshti hai.
