Bohr’s Complementarity

In quantum physics, each particle has a dual nature: It can act like a particle or a wave

But never both at the same time.
Each view "cancels" the other.

This is called the Principle of Complementarity, by Niels Bohr

“Seemingly opposite properties are not contradictory — but complementary.”

Just like in life:

We are not only logical or emotional, bright or dark.
We are all of these — at different times.

Heraclitus had said it long before:

“Opposition brings harmony — the most beautiful arises from differences.”

Unity is born from contrast.
And light is meaningful because darkness exists.

Thought Exercise Can you think of a contradiction inside you that might not be a contradiction — but a complement?

(e.g., "I’m both shy and brave, depending on the moment")
