Was that tidbit of intelligence a share too far? Or were you withholding a "spoiler"?

Theodora ur funny but being serious what I said was just guess! So HP wasn't holding out she just wasn't jumping to my conclusions!

 

Yeah! I know! And the same solution!

Sorry about that! -- While I recalled that Aleph experienced similar difficulty - it seems I ignored her solution (and, indeed, the existence of same - beyond what I assumed to be spontaneous 'remission')...

Yeah, ok fine. It's on tomorrow's GoToMeeting agenda.

So I say we just wait for that data then present it here in digested form!

Sounds like a plan!

Theodora u can say that but I'm still not sure what ur doing with your right hand?

May we cool it with the 'blue humor' please? -- This is, all said and done, a 'family friendly' site... Moreover it would be ungrateful and, frankly, rather bad form to take advantage of the latitude thus-far extended us by the moderation staff...

Very best regards

HP Sry abt that! But I say Theo didn't need to publicly whine abt her AT hatemail either!

 

Actually, I'd appreciate it if you @theodoravain and @Aleph(0) took a cleanup pass through the last couple of posts. As @Hypatia's Protege indicates, this is a family friendly site with people of all ages and types visiting. The photo and content clearly off-topic to the EHT project and in questionable taste at the least.
Thanks.

 

@JohnInTX -- Please see your PM!

Best regards
HP

 

@Aleph(0) @HP
I'll post the GTM results tonight

Thanks!

 

ATTN: @Aleph(0), @theodoravain

Let's keep it real simple, shall we? -- All I require at present is a straight answer as regards the desired/appropriate scope of the inductor/magnetics discussion! --- No need for 'webinars', 'GTM minutes', polls/studies, nor any manner of 'navel gazing' whatever! -- Merely a definite choice of 'primer' vs. 'description' -- Simple as that!

@theodoravain -- Email received and understood! - My bad! - I might have known you'd get 'no joy' from students on a Friday evening -- Sincere thanks for your efforts all the same!

Very best regards
HP

 

Merely a definite choice of 'primer' vs. 'description'

A definite answer will have to wait until Wednesday night. But fyi all I'm hearing is a call for where you're getting the numbers. And honestly! I don't like KN's encouraging them to code "hunting" algorithms! Grown adults should know how to rearrange algebraic formulas!

Thanks!

--Emphasis added--
Thank you! -- Please advise me immediately you have a solid consensus (Wed evening) -- Thanks also for sharing your 'sense' of the prevailing 'ethos'

I don't like KN's encouraging them to code "hunting" algorithms!

Neither do I! -- Many thanks for the 'heads up'! -- You may rest assured that I intend to personally 'nip' said travesty in the 'bud' -- immediately if not sooner!

Grown adults should know how to rearrange algebraic formulas!

Indeed! In 'my day' such skills were both expected and attained by year 7/KS3 (i.e. 'sixth grade'/eleven YOA)! --- Again, while we remain absolutely sincere in our pledge of patient assistance to those struggling with genuine challenges --- Laziness (and it's 'handmaiden' willful ignorance) cannot and will not be tolerated!

Best regards and many, many thanks!
HP

Yeah. I thought it best since Julie should be back on by then too.

Laziness (and it's 'handmaiden' willful ignorance) cannot and will not be tolerated!

Yeah! Seeing the trees is necessary but no substitute for beholding the forest. It doesn't much matter whether we stand for intellectual laziness or not. There's nothing we can do for them!

Thanks!

Theo I totally agree but I say worst thing is where Kathleen got idea and why so many ppl think it's ok is that's how _Numeric Solver_ app on TI89 calculator works!

So instead of just solving equation for selected dependent variable, app leaves formula in original form and keeps adjusting dependent variable (like search algorithm) until Eq is balanced within tolerance or just gives up after _excessive iterations_! I say it's totally lame of TI to set bad example of approximation by trial and error instead of proper solution! Cuz after all calculator is marketed as educational tool!

HP & Theo I totally agree! We're not expecting anybody to know material before studying on it but we totally insist they're willing to think for themselves! So that's presumption of intellect and competence HP and I are always talking abt! Cuz it's our absolute promise that we'll NEVER talk or teach down to anyone! But we also won't tolerate laziness or embracing ignorance! Cuz it's exactly like you say! It wouldn't help them at all even if we did!

Now I'm going to say something! We totally promise we're NOT and NEVER will be seeking profit or remuneration at all and we'd totally refuse it if offered! So our motives can totally be counted on as pure! So we're not trying 2b saints! Just ppl vry concerned abt how science is being co-opted and bastardized by political propagandists and carnival barkers and even worse given back seat to trifecta of mind-killing total evil which are: expediency, empiricism and pragmatism which I say are basically survival skills at best! Definitely not anything espoused by legitimate pedagogy with student's best interests at heart!

Again, while we remain absolutely sincere in our pledge of patient assistance to those struggling with genuine challenges

HP ur totally right! All we're asking is for ppl to have honest desire to learn and willingness to put forth effort! We totally promise not to leave any sincere ppl behind! Now I'm saying to anybody thinking that's just hollow reassurance plz look on our efforts to help some ppl right here on AAC forums that most other active members wrote off as trolls! So we're totally patient with ppl who even MIGHT be making honest effort cuz there's just too much at stake risking leaving ppl behind!

Yeah. I thought it best since Julie should be back on by then too.

Theo tnx! Being totally honest since that whole f'up is basically my fault I say it's best I'm active on here when decision is made too So anyhow just _for record_ reason decoupling choke has gotten way disproportionate attention is just us trying to distinguish like _horse from cart_ for order of topics!

 

we're not trying 2b saints!

True. You did a pretty good job with RK, FWIW.

Well of course TI included the APP as an expedient. It's better for business to spoon feed numeric "solutions" than attempt to explain the facts of life to users who don't know or care to know. So when the Home Screen doesn't render general solutions that don't exist (Ex. for "fully-termed" transquartics, some inverse and all discontinuous functions et cetra) the lamers may have "answers" from the NS APP. Of course they'll seldom have all "answers" and never any comprehension of anything! But they won't be telling their buds "the calculator can't handle it" either. I don't blame TI. I'm way past trying to steal illusions from confirmed idiots!

or just gives up after _excessive iterations_!

Yeah! Newton-Raphson would help that! Pearls before swine and all.

All we're asking is for ppl to have honest desire to learn and willingness to put forth effort! We totally promise not to leave any sincere ppl behind!

Of course! I want everyone to know that "lamers" and "idiots" exclusively describe people who insist on ignorance. Honestly! I'm easier to get along with than my avatar suggests

Thanks!

Ah... Sanity! -- An enviable condition to be certain! -- Sincere congratulations!

Yeah! Newton-Raphson would help that! Pearls before swine and all.

Re: Polynomial equations -- In my considered opinion (FWIW) said APP's limitations (Spec: location of only a single root, protracted 'run-time' [and hence, I can but assume, high 'iteration count'], relative imprecision and frequent failure) would seem to indicate implementation of 'Ruffini–Horner' (or a variant thereof)...

I don't blame TI

Indeed! -- IMNSHO the TI-89 Titanium and, especially, the (now discontinued) 'Voyage 200 PLT' are very nice! -- Sadly, TI's (IMO bizarre on to suspect?) emphasis upon 'education' --to the exclusion of all else-- has seriously diminished the utility of their more recent offerings (don't even get me started on 'Nspire')...

Honestly! I'm easier to get along with than my avatar suggests

A kinder, gentler, Theodora?! -- I very much doubt the world is prepared for that!

Very best regards

Ain't it the truth? -- The abysmal sense of 'violation', 'humiliation' and 'indignity' attending the very notion of some lecher clandestinely surveying my osteology defies description!

This is beautiful! The UK server locked out. Now I'm bouncing between DE and US routes! Well, I'm good so far and not holding my breath!

Yeah, well.. That's as good a guess as any and I suppose better than most. Really? Like there isn't more meaningful fill for "the empty spaces"? I know reverse engineering TI calculator apps hasn't made my bucket list yet.

Sadly, TI's (IMO bizarre on to suspect?) emphasis upon 'education' --to the exclusion of all else--

Not so bizarre really. They know engineers expect their CAD and math suites on versatile platforms. But pocket "Wolfram" is appealing to students!

Ah... Sanity! -- An enviable condition to be certain!

Speak for yourself!

A definite answer will have to wait until Wednesday night.

In just a few hours Zenmate permitting.

So I say we just wait for that data then present it here in digested form!

Standing by. Forefinger and ipecac at the ready

Thanks!

 

@HP
Good news (I think?) Babs B's poll supports my guess that there's not much appetite for an in-depth treatise on the physics of magnetic components at this stage. Of course you know that Lori H. and Julie have received multiple requests for a "simple" explanation of parameter selection & calculation (I took the liberty of telling them you were laboring under that assumption). Well there it is! All as expected! Nice to have gotten it right for a change!

Oh Yeah. Julie wants all to know she'll up the formal report as soon as possible.

Thanks!
