This world is great and science is great to but most importantly it should be updated . I still cant figure out why we need to learn detivations as it doesn't seem to have a well use in real life concepts and theories are find our education system doesnt pamper creativity thats the main problem. I as a student really feel like we are maintained and deprived to follow our passions thats why we are not able yo cop up with Indian education
