Fun to imagine-Richard Feynman-fire[附带中文翻译字幕]

A short clip from a Richard Feynman interview in which he explains fire, describing how burning wood releases sunlight stored by the tree, which built itself mostly from air. It showcases his curiosity and plain-spoken explanations.

Why HN likes it: HN repeatedly cites it as an elegant, eye-opening explanation of fire and photosynthesis and as an example of Feynman's infectious love of knowledge.

“it's impossible to stay in any kind of negative mood if you watch Feynman”
