This is well into the quantum realm, where quantum mechanical effects become very important.

But once again, scientists had underestimated the strange things that are possible on the quantum realm.

Quantum mechanical effects are very important at this scale, which is in the quantum realm.

The quantum realm can also sometimes paradoxically involve actions at long distances.

Molecular electronics operates in the quantum realm of distances less than 100 nanometers.

Metaphors are always inexact; in the quantum realm they are stretched to the breaking point.

The canonical approach for coaxing a classical system into the quantum realm is to cool it down until it reaches its "ground state."

How do the weird rules of the quantum realm give rise to the rock-solid, either-or certainty in what we quaintly call the real world?

Chapter 7, "Time and the Quantum", gives insights into time's nature in the quantum realm.

Without any fanfare, the quantum realm reversed itself, returning to its original monochromatic schema.
