Prerequisites
Before you start
Read computing foundations — start from zero first. You will reuse variables, unit conversions, binary representations and the habit of stating a model's assumptions. This route introduces the Physics area of the editorial map. It is an original reading sequence, not a claim to cover an entire physics curriculum.
You need a sheet of paper and basic arithmetic. Every exercise is a calculation or interpretation; no equipment or physical construction is required. The chapters and answers are in English, matching the library's current editorial policy.
Follow the five chapters
- Electricity: separate charge, current, voltage, resistance, power and energy.
- Electromagnetism: read an electric force's sign and calculate an emf from a stipulated flux change.
- Quantum basics: distinguish amplitude from probability and read fictional energy levels.
- Thermodynamics: choose a system boundary, balance energy and state what a temperature calculation requires.
- Solid-state physics: read a repeating-site model and distinguish allowed energy bands from carrier occupation.
Use the ordered reading links below. Each chapter states its prerequisites, works through invented numerical examples and ends with exercises and answers. References support the subject matter; they do not endorse this route or its fictional devices.
Check your understanding
- Under the ideal resistor assumptions, what current flows through 1000 Ω at 3 V?
- Does an induced emf by itself determine a loop's current?
- What probability follows from a specified real outcome amplitude of 0.6?
- A module receives 4 J and exports 1 J as heat. What is its internal-energy increase under the stated closed-system assumptions?
- Does a band diagram alone specify the current through a real semiconductor?
Answers and scope
The current is 3 mA. An emf still needs a circuit model to determine current. The probability is 0.36. The internal-energy increase is 3 J. A band diagram alone is insufficient to determine current.
To finish, explain why each answer depends on a definition or assumption. Being able to repeat the number is only the beginning. The source chapters on circuits, fields, quantum behavior, thermodynamics and lattices provide deeper treatments; their mathematics goes beyond this introductory route.
Continue through the stack
Continue with chemistry and materials — from atoms to doped silicon. Its five lessons build on these physics models to explain bonding, crystal structures, silicon and oxide, doping and sample properties.
You can also follow digital logic foundations for symbolic rules and circuits. The full computing stack shows the available articles and planned domains.
