Primer · ten volumes
Field manuals you can poke.
Short labs, one idea each. Read the plain-English box, poke the diagram, keep one sentence. Algebra sits under the mind volumes. Rockets sit under the space ones.
In English
Each volume is a stack of short labs. Read the plain-English box, poke the diagram, keep one sentence. If later volumes feel like a foreign language, start with Algebra. If you want space, start with Rockets.
- Try this
- New to all of this? Algebra, then Information, then LLMs. Here for agents? Start with Tokens. Here for space? Delta-v.
- Keep this
- One idea per lab. Click it. Then go on.
- Volume ILLMs語言模型How a language model thinks — and how engineers wire it.Tokens, attention, the cache, the loop, the harness.
- Volume IIQuantum量子A state is a direction. Measurement is a question you only get to ask once.Superposition, interference, entanglement, Deutsch.
- Volume IIIComputing計算Physics is the substrate. This is the computer: registers, oracles, Grover, the fridge.Registers, Grover, teleportation, the stack.
- Volume IVAlgebra代數The shared language. Vectors, maps, the arrows that only stretch.Vector, matrix, eigen, projection.
- Volume VLearning學習The model is a fitted function. Loss, a slope, a step, then the ways that fails.Loss, gradient, backprop, overfit.
- Volume VIInformation資訊Surprise you can count. Entropy, KL, and the number an LLM actually minimizes.Bits, entropy, cross-entropy, compression.
- Volume VIICrypto密碼One-way functions, RSA, the discrete log — and the stories Shor makes false.Mod, RSA, hashes, the threat.
- Volume VIIIRockets火箭Mass ratio, a jet of gas, and 9.4 km/s of bill to LEO.Delta-v, staging, engines, heat.
- Volume IXOrbit軌道Circles, ellipses, Hohmann, the expensive plane change, escape.Kepler, parks, transfers.
- Volume XLEO低軌Close, fast, crowded. Latency, a flock, drag, debris.Why LEO, constellations, Kessler.
