OT: Being Helpful

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

I can't (don't try to) remember which vendors use which words. Regardless, learning the basics will enable you to spot bullshit whether it uses the word quantum or something else, like electron realignment.

I've never heard of Shunyata.

It's a manufacturer of overpriced audio accessories named after snakes.

any consumer audio device that uses the word quantum is suspect

I don't have a boat and don't spend enough time on others', but sailing is one of my very favorite things in the world.

Jud, you’re always welcome!

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

Richard Feynmann's first 2 volumes are really interesting to read, but I found it hard to learn physics from them.  He taught at CalTech, so likely just assumed everybody would figure out the physics on their own.

 

He also solved a lot of Oppenheimer's equations, after they took him from the Univ. of Chicago in the middle of the night to go to Los Alamos.

The thread's title begins with Off Topic. Doesn't that mean points are awarded for diversion?

Here is an interesting read, somewhat related... somewhat diversion.

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.

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

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.

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.

hey man, have a fify on me

biosailor - a good mathematics/physics text book to start with would be the Berkeley books series - that is what I used as a young physics major back in the Late Holocene.  You can stop with the sophomore sequence - Jr. year was quantum theory, not needed for audio.

 

Richard Feynmann's first 2 volumes are really interesting to read, but I found it hard to learn physics from them.  He taught at CalTech, so likely just assumed everybody would figure out the physics on their own.

Another approach would be to go thru the physics textbooks that engineering students use.  In their physics courses, a simpler more conceptual approach is used (tho not the guff you find in physics for poets classes) so it ill be a lot easier (leading to many jokes about lookup tables).  Holliday & Resnick is an older one (we called it Holiday and Redneck).

 

Finally, re sailboats, you might find it fun to look at the literature on fluid dynamics - you can stop in the 1930s as the work went into supersonics at that point.

 

Thanks for the suggestion. I'll put my mind into it!

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

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

 

I used to have quantum theory in my chemistry courses. Was the hardest bit I had to swallow ever! Don't know if I ever recovered from the shock 😀!

 

However, signal theory/DSP doesn't use quantum physics at all, if I am not mistaken.

No, that's just maths, and lots of it. In electronics, quantum physics is necessary to understand semiconductors. It also explains how metals work at the fundamental level, and while you don't need to care about that in everyday use, it makes the technobabble from the cable companies funnier.

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

I took this thread as going in a somewhat different direction.  I'll admit that the concepts below at first struck me as at least counter-intuitive, and at worst, crackpot.

 

But the crux is that cooperation trumps competition every time.

And yet you say there is no room for civility? Would that not be the first step in getting everyone to cooperate?
