Wavefunction Collapse
Quick fact
In quantum mechanics, measuring a particle instantly forces it into one specific state from many possible ones.
Why this is interesting
Have you ever wondered why particles seem to 'choose' a position when measured? It's not random—it’s called wavefunction collapse.

Understanding Wavefunction Collapse
Imagine a spinning coin in the air—before you catch it, it has all possible outcomes. But when you look, it settles on heads or tails. This is like wavefunction collapse: the act of measurement 'chooses' one outcome from many possibilities.
A deeper explanation
Wavefunction collapse occurs when a quantum system interacts with an observer or measuring device, causing its state to transition from a probabilistic superposition to a single definite state. This process highlights the fundamental difference between classical and quantum systems—observation itself changes what we observe.
