值得注意

当一个定义与可测量或可观察的现象连接起来时,科学才真正容易记住。

Take one idea at a time. If a new word appears, connect it to a concrete object, number or experiment before moving on.

Start with the central idea, then test it against a concrete element or example. A scientific model is useful when we know what it explains — and where its limits are.
