- waynesonfire 5y agoThis whole series is amazing.
- modeless 5y agoHere it is in better quality, the whole thing, and with subtitles: https://www.youtube.com/watch?v=nYg6jzotiAc https://www.youtube.com/watch?v=nYg6jzotiAc Particularly good parts are the explanation of fire and trees ("trees come out of the air"): https://youtu.be/nYg6jzotiAc?t=440 https://youtu.be/nYg6jzotiAc?t=440 and the explanation of the mirror problem, i.e. how does a mirror know to reverse left and right but not up and down: https://youtu.be/nYg6jzotiAc?t=1976 https://youtu.be/nYg6jzotiAc?t=1976
- fouronnes3 5y agoThe mirror thing is the one that every time I think: yes! this time I understand it! Then I think about it a bit more and nope. Black magic.

- Nition 5y agoI realise this isn't a very helpful comment in itself, but I hope Hacker News comments don't go the way Reddit comments have, where they routinely post and upvote content that's already in the linked article (usually because few people read beyond the title). In this case - just reposting the Feynman video - it's fine, but in other cases it leads to a lot of uninformed or unnecessary discussion, sometimes speculating on some hypothetical that the article already answers.
