Joule Thief 101

[MileHigh]

No, we were having a discussion about resonance and I suspected that some people were bluffing about it.  You know, like how 95% of the people that build stuff with coils and post about them all the time don't actually understand how they work?

So I posted these two simple questions and requested two simple answers:

How does a wine glass resonate, what is the mechanism?
How is the resonant frequency of a wine glass determined?

And low and behold, nobody has been able to answer them correctly in their own words.  So what are the implications for people that are trying to experiment with resonance?

The questions were posed because of Brad's big talk about resonance, and it's turned out to be big fake talk and a bunch of copy-pasting.  That's a worthwhile exercise whether you like it or not.  It has devolved into a bloody circus and that's not my doing.  Answers will be provided in April.  If people had the right attitude they would take up the challenge and try to answer these simple questions by learning and then distilling that knowledge and comprehending it so that they could successfully answer the two questions.  On another forum where people take pride in educating themselves in the information age they would welcome this as a fun challenge.  Instead you have a circus with a bunch of poseurs that aren't happy that they can't talk the talk anymore because someone asked them to walk the walk and they couldn't do it.  All that they could do was complain and copy/paste, they couldn't use their own brains and intellect to answer the questions.  But they still can if they want to work at it.  Experience has shown they will not learn if it's spoon fed to them.

If you don't like it, tough for you.

Going to electronics pre-101

I asked this a long time ago elsewhere but did not get an answer,,

A conductor has a relaxation time period before it starts to conduct,, does an inductor have that same delay?

Yes, it is the inverse of its resonance frequency.


Actually, I just made that up...but it sounded reasonable didn't it?  I actually have no idea what the answer to your question really is.  Sorry.


Bill


PS  I would think that it would vary with the permeability of the inductor though. (Seriously)

 MH
As regards TinMan and Smokey and your education of same and claim that they are faking it ?

I just got my crystal ball back from the shop...
I see that you have  no clothing  ? ( the Emperor has no cloths??) And egg on face..

Could be on the fritz again that atom guy really made a mess of it...
Although,
I suppose in Tinmans case he probably has something in his seven thousand videos
That will serve up crow ?

Enjoy you spring time !

What's the matter with you, Chet?   You explain to us what a magnet *really* is?  You can't?  Whoops, not a single other person on this forum can either, can they?  And yet you want to single me out?  That is the lamest BS you are trying to pull on me.  In your previous posting you played straw-man with me and said I made statements that I didn't make.  Even you, not being technical, can spot Brad's continuous stream of ridiculous gaffes and you say nothing.

You are in a straitjacket and you are casting stones at me like a mindless drone because "forum political correctness" has told you to do it.  Go back and read "The Lottery" and bow your head in shame.

actually MH,  I know for a fact that at least 4 of us can do a pretty good job at it.
perhaps more, I don't "know" everyone well enough to make broad assumptions like that.

The problem I see with attempting to explain it to you, is the gaps in your logic.
You seem to have trouble following a coherent language-based discussion.
How could I ever expect you to be able to follow a quantum atomic loop around a single rendition.
much less the "countably infinite" number of renditions one must calculate to grasp a basic understanding of the magnetic moment.
Which occurs at something over a million THz in a monoatomic (Fe).

Then expect you to be able to add up all these quantities and their associated angular vectors to apply this to a mass-field scenario.

In all honesty, the way this thread has been going,
I would venture to say it is easier to perform long drawn out trigonometric derivations
than it is to teach a simply basic concept of wave interference to Milehigh.

It is beyond the point of ridiculousness. I am not sure at this point, if you are just not paying attention, if you habitually forget what was stated,
or that you just enjoy the confrontation (attention, etc) of being the naysayer. I am unsure of your intentions here.

And now, once again, just for you MH, I will do what I said I was NOT going to do...
(seems like a waste of time, but what the hell, you actually seem interested in the answer for once....)

The highlighted stuff must be you mistaking me for somebody else.

We are not here to talk about quantum physics, and that's a subject that I know next to nothing about.  Likewise I didn't ask you to explain anything about this to me, did I?

I made a posting to you where I asked some follow-up questions to one of your postings.

Beyond that, I am asking you to answer my two simple questions about the wine glass in your own words with simple, succinct answers - four sentences or less.  No discussion of fluid in the glass, no finger rubbing the rim, absolutely no copy/paste.  Just answer the questions in your own words.  Are you capable of doing that?
