This is the front door the site was missing: choose what you are in the mood for, scan the archive, and jump into a curated path instead of staring at a static homepage.
Choose Your Mood
Engineer Run
Start with technical notes, then jump into physics models when you want sharper mental machinery.
Cosmic Scale Dive
A dramatic route from human-scale intuition to planetary and cosmic perspective.
Observatory Sweep
A high-visual route for first-time visitors who should instantly feel where the site lives.
Archive Excavation
For returning visitors: surface resources, documents, and deeper study material without wandering.
专题任务栈
把内容打包成更明确的浏览目的：访客可以按“一分钟体验、深空、推理、工程、媒体、实验”直接进入。
Instant Hook
The page gives visitors a decision immediately instead of asking them to scroll blindly.
Useful Motion
Animation reacts to clicks, selection, scanning, and route ranking instead of floating for decoration only.
Site Gateway
Every recommended card is a real link into existing content, so the cool layer also improves navigation.
