kramabaddh evn vishisht gyan ko vigyan kahate hain. vigyan se ashay aise gyan se hai, jo yatharth ho, jisaka parikshan aur prayog kiya ja sake tatha jisake bare men bhavishyavani sambhav ho. isake siddhant aur niyam sarvadeshik aur sarvakalik hote hain tatha inaka vishad vivechan sambhav hai. vigyan angrezi ke shabd sains (Science) ka hindi roopantar hai, isaki utpatti laitin bhasha ke shabd Scientia se huee hai. Scientia ka arth hai, gyan ya janana. vastav men is bhautik jagat men kuchh bhi ghatit ho raha hai, usaka kramabaddh adhyayan hi vigyan hai. yah spasht ham apane charon or ki srishti ka gyan apani gyanendriyon dvara kar sakate hain, parantu is bhautik jagat men kuchh aisi atyant sookshm kriyaen hain, jinaka gyan ham sidhe apani indriyon se nahin kar sakate. isake hamen atyant sookshmagrahi yantron ka upayog karana pad sakata hai. yahan prashn uthata hai ki gyan se vigyan ka kya sambandh hai? vastav men prakritik ghatanaon ka adhyayan karana tatha unamen apas men sambandh gyat karane ka nam hi 'vigyan' hain thaaumas haaubs ke anusar:-
Science is the knowledge of consequences and dependence of one fact upon another.

prakritik vigyan

manav adikal se hi apane charon or ghatit prakritik drishyon, ghatanaon adi ko dekhata raha hai. akash ka nila dikhaee dena, ugate v doobate soory ka lal dikhaee dena, badal men bijali chamakana v kadakana, samudr men jvar–bhata ana, varsha ke bad indradhanush ka dikhayi dena adi prakritik ghatanaon ko janane ke lie prarambh se manav utsuk raha hoga tatha inaki khoj apani matr buddhi evn tarkapoorn anuman se hi, balki prayogon dvara karata raha hoga. is prakar se adhyayan se manav ne yah nishkarsh nikala ki har ghatana kisi prakritik ke anusar hi hoti hai v suvyavasthit janakari ko prakritik vigyan kahate hain.
