The Uncertainty Principle
For macroscopic objects, the momentum from the photonsâ€™ impact will have no measurable effect. Discuss why this is different for atomic-sized objects. Why does shining (very short wavelength) photons on electrons not tell you exactly where the electron is?
Discuss how taking some everyday measurementsâ€”such as the temperature of a water bath, voltage, current, the pressure in your bicycle tires, and other examples you can think ofâ€”somehow changes the original thing you were measuring.
