Topic list
[edit]- What is quantum mechanics?
- A curiously exotic set of phenomena.
- theoretical model of very very tiny things.
- Major part of how the universe works.
- strangely: all of the above.
- Why is quantum mechanics difficult to understand?
- Quantum world fundamentally different (intro).
- Invisible, Heavily mathematical, Ubiquity, Different properties.
- Invisible leads to indirect observations.
- Indirect information: observations.
- Submicroscopic scale.
- Macroscopic human senses.
- Information through interaction.
- Interaction causes alteration:
- Observations alter state.
- Environment alters (decoherence).
- Indirect information leads to models leads to math.
- Models predicting observations.
- Numerical observations require mathematical models.
- Limitations of non-mathematical descriptions.
- Models difficult to explain without math background.
- Only analogies to directly observable systems.
- Limitations of mathematical description.
- Bad data to start (unmeasurable initial conditions)
- Observers obey QM (Heisenberg cut)
- Quantum world fundamentally different (intro).
- Curiously exotic phenomena and our models of very very tiny things.
- Photo electric effect: quanta.
- Photoabsorption: bound states and quantum jumps
- Double slit: interference and matter waves.
- Single slit: interference and yes waves.
- Double slit low intensity: probability.
- Radioactive decay: probability.
- Stern-gerlach: spin
- separate measurements in coincidence: entanglement.
- A major part of how the universe works.
- Ubiquity.
- Quantum apparatus; quantum observers.
- Welcome to the edge of the known universe.
