## Overview

A science and systems-literacy guide built from 123 technical explainers. Each chapter deconstructs the engineering, business, and physical mechanisms behind familiar modern systems.

## Core Topics

- **Consumer Hardware**: Camera optical zoom limits, USB-C standard fragmentation, JPEG longevity, display tech.
- **AI & Internet Infrastructure**: Data center capex payback, LLM hallucination, cross-platform tracking, captcha defenses.
- **Vehicles & Mobility**: EV battery degradation, real-world vs. lab range, smart-driving terminology.
- **Health & Everyday Science**: Disease mechanisms, medical screening, media codecs, consumer product trade-offs.

## Study Method

1. **Frame the question**: State the visible paradox or question first.
2. **Deconstruct the mechanism**: Isolate physical constraints from commercial marketing.
3. **Capture terminology**: Collect paired technical terms and concise explanatory structures.
