Paradigm shift.
All about the way we see things & our thoughts start striking into the mind. Technology & new theories have been discovered in this way only.
For example; Aristotle watched a stone swinging like a pendulum on the end of a rope, he would see the stone trying to reach its natural state: at rest, on the ground. But Newton wouldn’t see this; he’d see a stone obeying the laws of gravity and energy transference.
