This highlights the odd connection between the one observing and what’s being observed in the quantum world. The observer effect is key in quantum physics, showing how just watching can change what happens in an experiment.
The double-slit experiment is a great example of this. It shows how observing particles, like electrons, can change their behavior. When watched, electrons act like particles, making two clear patterns on a screen. But without watching, they act like waves, creating an interference pattern. This experiment shows how important measurement and the observer effect are in understanding quantum physics.
