In 1927, Heisenberg proposes uncertainty principle
to describe precisely the indeterminacy that exists at the very core of nature,
whereby you could never know with absolute precision both the position
and the velocity of a particle.
If you try to make a mental picture of this,
Heisenberg is saying that everything in nature is jittery
and that this inherent agitation is at the very core of matter
and will not go away.
The new quantum physics opened the door to a very, very different
physical reality.
