Henry Miller
The caricature of science is that we hold tight to the theories we have, and shun challenges to them. That’s just not true. In fact, we hold our highest rewards for those scientists who can prove others wrong. And by the way, they are famous in their own lifetimes. We don’t wait until they’re dead.
Neil deGrasse Tyson
The planet Mars – crimson and bright, filling our telescopes with vague intimations of almost-familiar landforms – has long formed a celestial tabula rasa on which we have inscribed our planetological theories, utopian fantasies, and fears of alien invasion or ecological ruin.

Theories of history used to be supernatural: the divine

Theories of history used to be supernatural: the divine ruled time; the hand of God, a special providence, lay behind the fall of each sparrow.

Richard P. Feynman
The primary difference that I have found between the system of education in India and other countries, particularly the U.S., is that they focus on problem solving and relating theories to reality around them. These two things are lacking in the education system in India.
