In the ancient times (till the beginning of 17th Century),the civilizations were based & bound together by Religion.If a man had any questions regarding his position in Universe,he had to look for answers in the scriptures.More older the religion,more profound & mystic were its values & beliefs.
During this time,Science had just started taking baby steps.With the arrival of Newton,classical physics gave a hope to everyone,that there was no need for any magical story or belief.A man,by simple observation & study of nature can understand the working of what previously seemed to be an incomprehensible Universe.
It is the nature of human being not to easily accept something which is new as well as challenging to his long held beliefs,even if the proofs are available.Hence,this was the time (A period between 17th & 20th century–different for different countries) when people still held to their religious beliefs & had a prejudice against the up coming Science.
During these three centuries,Science was blessed with genius of Max Plank,Neil Bohr,Heisenberg,Thomas Edison,Albert Einstein (the list is long).It gave our world a prefix-‘MODERN’.Science did not remain limited to England,Germany,Russia but it gradually spread to the whole world.Every single school going child,now had an opportunity to learn about the great works done by these genius.(Not only an opportunity,but also a compulsion if you are a Science student!)
So the youth of my generation were brought up under Scientific values.And the children have this habit of accepting something which involves logical reasoning rather than a belief system.
