Nevertheless, it‘s an interesting site full of great links!

 

Yes, I've always thought since I ran across it years ago that it's an autodidact's heaven that I'd like to take advantage of when I retire.

Since my recent retirement, I thought I finally want to understand what all those audio specialists mean by filters, sampling, transfer functions, fourier transformation and what not.

 

Yep, my thinking exactly!

 

And even a failed attempt would be hella interesting, I think.

I do wonder, however, if he has ever really had to produce a work product other than some open ended research into the vast unknown.  That's an easy life.

 

My supposition would be that an extra measure of rigor is needed for research into "the vast unknown." I remember the smartest guy I've ever known personally, a childhood friend who's now an astrophysicist with experiments on the Hubble and a publications list longer than both arms, shaking his head with a rueful grin after a semester at Princeton and saying to me "I found out I'm no theorist."

 

t'Hooft pretty much invented renormalization. https://en.m.wikipedia.org/wiki/Renormalization

 

I'm guessing that was hard work.

And much of it is pure speculation based on erroneous earlier assumptions and whole careers are wasted chasing unicorns.  Then along comes an Einstein or Hawking and re-calibrates everybody and the herd is off on the next chase.  Thankfully along the way a small (albeit very small) percentage of ideas and theories become corroborated (e.g. Higgs Boson).   It is very hard and requires extreme rigor because it's all abstract until you can build a Hadron Collider!!!

Actually, do read a bit about quantum theory. Then you'll see that the "explanations" offered by Shunyata and that lot are utter nonsense.


Reference to such explanations offered by Shunyata? Synergistic is known for “quantum” stuff but hadn’t seen Shunyata.

OK, I had thought this thread was about learning about physics in your spare time.

 

It's about being helpful.

I understand he was quite the jokester, and once propositioned Oppenheimer's wife at one of their weekly parties.  Her reply was: "Surely you're joking, Mr. Feynman!"

 

He had a reputation for being rather boorish around women, so that seems like a graceful way to deflect on her part.

It certainly seems to follow the Internet Law of Misquoting.

You expect me to read AND understand?


I didn’t say what Ralf11 represents as a quote from me, nor have I been able to find that language elsewhere in the thread.

I was going to change "said" to 'didn't say' but this forum software denied that


You remember the use of quotation marks from English class, so not sure why you felt the need to try to play with the forum formatting, or post the result when it didn’t work, but hey, whatever.

Same here, but you'd have to come to Switzerland. Sailing on those moutain-like lakes is a dream!

Loved sailing on Lake Pend Orielle in the Rocky Mountains in Idaho. We had Nutella so it was just like Switzerland! 😉

Anyone have additional helpful resources for auto-didacts, particularly (but not exclusively) free and web- or app-based?

Well, for one (or actually everything) - there's a browser extension called Unpaywall, that can find if there are any free versions available of academic journal articles that you initially find behind a paywall. Let's say you see something fascinating in the latest issue of "Nature" - this will point you to the free version on, for example, arxiv.org if it exists.

By the way, an approachable blog on subjects including computational complexity and quantum computing, with the author’s textbook, “Quantum Computing Since Democritus,” is here: https://www.scottaaronson.com/blog/
