Observador (Física)

The video discusses how observers record observable properties of systems, like velocity, and the assumption that observers do not affect these systems. However, in reality, especially in particle physics, observers do impact the systems they observe, as detecting particles requires interaction.

What is typically assumed about the observer's impact on a system when recording observable properties?

• The observer sometimes affects the system.

• The observer never affects the system.

• The observer's impact is unpredictable.

• The observer always affects the system.

In reality, how often does the observer affect the system they are observing?

• Often

• Rarely

• Never

• Always

Why is it impossible to detect a particle without interaction in particle physics?

• The technology is not advanced enough.

• Particles move too fast to be observed.

• Detection methods inherently involve interaction.

• Particles are too small to observe directly.

What is a key challenge in particle physics regarding observation?

• Detection always involves interaction.

• Observation does not require interaction.

• Particles are too large to detect.

• Particles are stationary.

Which field of study highlights the observer's effect on the system?

• Astrophysics

• Particle Physics

• Thermodynamics

• Classical Mechanics
