Observer

The video tutorial explains the concept of an observer in physics, highlighting that an observer records observable properties of a system, such as velocity. It challenges the assumption that observers do not affect the system, particularly in particle physics, where detecting a particle inherently involves interaction, thus affecting the system.

What is the definition of an observer in physics?

What observable property might an observer record?

Why do we usually assume that the observer will not affect the system?

What is the implication of detecting a particle in particle physics?

How does the interaction of an observer with a system challenge the assumption of non-influence?
