Is this worth reading for someone without a particular need to understand physics in depth? What I mean is if I take the time to read these will I learn anything useful to someone not pursuing a career in physics or related field?

> Is this worth reading for someone without a particular need to understand physics in depth?

For someone just curious about modern physics, without any specialized knowledge or advanced mathematical skill, it might be overwhelming.

I suspect many of us would say yes. One of the things Feynman was known for was his knack for bringing ideas down to earth.

As he opens in QED, you won't be able to solve heavy physics problems analytically in a short period of time, but with a little effort, you'll certainly be able to qualitatively understand the situation. And there's quite a lot of beauty to have there, even without heavy math (but there will be math!)

If you're reading it "on line" you've already downloaded it.

Yeah, but you can't put it easily on your tablet and read it offline while sitting in the park ;-) Still liking it a lot.

That's what I was wondering about. You'd be saving the lectures, not downloading them, if you did that. The license needs some clarity.

Feynman lectures on QED: https://www.youtube.com/watch?v=yvl6TBGEoO0 https://www.youtube.com/watch?v=xjdbbnWsdis https://www.youtube.com/watch?v=FF25Lwt73fg https://www.youtube.com/watch?v=BtK6FdTg9HU

I have to disable safety mode to watch these? WTF?

I don't know what "safety mode" is, but I didn't need to disable anything to watch the videos.

every now and then i go into the library and read a chapter out of my hardcover set of these. my kids do the "geeez dad" thing when i make them sit with me and look at them. classics.. to be sure.... edit: i almost feel like these shouldn't be something that gets digitized.....this knowledge and its presentation belongs in a tactile medium...

The plural of anecdote is data, so FWIW I'm exactly the opposite: not just for textbooks, but even for hardcover literature books I have right there in my bookshelf, I often end up digging up some PDF or Google Books version regardless. I guess I miss the scrolling/zooming, plus all the meta-textual, cross-referencing stuff like having multiple copies of the book in different sections side by side, easy access to references and definitions, etc.

What one finds 'classical' is highly relative: remember Socrates famously despised books as a degrading and pernicious medium, for one [1].

Yes, it is especially useful as they are vary approachable. That said they are also as deep as any 3 semester course in physics you're likely to take so at some point you will need the math skills to keep up.

It's an optional Youtube setting.

From the landing page: "However, we want to be clear that this edition is only free to read online, and this posting does not transfer any right to download all or any portion of The Feynman Lectures on Physics for any purpose."

They don't know what the word "download" means. This statement is nonsense.

"Download", as used in practice on the internet when referring to documents generally means copying the whole thing to your computer such that it can be used there without further internet access.

It generally does not include temporary transfer of small parts of the document for immediate reading, except when the focus of the discussion is about the underlying mechanics of the transfer.

This supposed duality is nonsense. A change of cache settings in your browser amounts to the same result. There's no such thing as a "temporary transfer", and I think we should not entertain the notion.

"Saving" vs. "Downloading" is not a duality we should entertain either. If it is downloaded, it is likely saved to a permanent storage, and maaaybe some process will eventually delete it. In any case this should not be the territory for law.
