Key ideas in Quantum Physics for the Curious
- Modern transistors perform the same basic switching job that bulky vacuum tubes once did
- In a semiconductor, what exactly is a 'band gap'?
- To turn a semiconductor 'on,' we must provide enough energy to push electrons across the gap
- Quantum mechanics is the reason your phone can fit billions of switches on a single chip
- The size of the energy gap determines how easily a material conducts electricity
- Digital 'on/off' states require the controllable flow found in semiconductors
- How energy gaps determine if a material can be used as a digital switch
- Mapping material behavior to its digital function based on electron movement
- The relationship between quantum mechanics and the miniaturization of electronics
- Protons have a positive charge that repels other protons
- Gravity provides the pressure and heat for the core
- Quantum tunneling allows particles to 'leak' through energy barriers they cannot climb over
- Without tunneling, much higher temperatures/pressures are required for protons to touch
- The Coulomb barrier is the repulsive force between like charges
- How quantum tunneling allows fusion at lower temperatures
- Fusion is the payoff when the barrier is bypassed
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Quantum Physics for the Curious the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
