By the end you'll be able to
- Describe what quantum mechanics is and identify the length and energy scales at which its effects dominate.
- State the value and units of Planck's constant, convert between h and ħ, and use E = hf to find the energy of a single quantum.
- Name and define the five big ideas of the course: quantization, wave-particle duality, superposition, uncertainty and entanglement.
- Explain why the electron's magnetic moment makes quantum theory the most precisely tested theory in science.
- Connect transistors, lasers, LEDs, MRI, GPS clocks and solar cells to the quantum effects that make them work.
- Use scientific notation to compare sizes that differ by dozens of powers of ten, and correct three popular myths about the word quantum.
