Ok...?Short and hot,I just micro waved some food.....I put hot sauce on every spoon

Here's a 'like' for the count!

Now I get it through my concrete cranium! I only needed think how to make detector and a duh! Got it! Now I'm thinking how it would be if vision respond to longer wavelengths like 20m! Not only sky and surface like crinkled al foil but need to travel large distances while viewing with special memory skill to piece big picture together Going other way if retinal cells stimulated only by uvd (like 100-200nm) all world shrouded in dense fog cause O2 opaque to uvd! With xray and gamma ray vision we'd all be hopelessly lost in like Mr Lovecraft's _Walls of Eryx_! So means evolution or creator or however you believe we came to be, got it right with just regular light!Hint - Think nodes, anti-nodes and intervening distances thereof...
(Note, however, that the notion of 'standing waves' per se isn't especially germane to the concept at hand)
I know you right, It's just not easy to strike off all those years I say more by e...and that's no way to have to be! -- We need to talk!
Then too, a CW transmitter and 1/2λ Yagi make for a rather cumbersome flashlight (i.e. torch)!Now I'm thinking how it would be if vision respond to longer wavelengths like 20m! Not only sky and surface like crinkled al foil but need to travel large distances while viewing with special memory skill to piece big picture together
T'would be even worse than that! -- Indeed - owing to its (diatomic) oxygen content, air, under tropospheric conditions, is several orders of magnitude more attenuative of 'UVD' than is, for instance, seawater of visible light - yet, in the latter case, light is (generally accepted to be) perceptible to depths of merely 200m and detectable to only 1km --- whereas the troposphere might be regarded as fully 11km 'deep' -- Inasmuch as you seem to appreciate Lovecraft, let us say; The world as seen through 'UVD eyes' would be as the Stygian blackness of the pitif retinal cells stimulated only by uvd (like 100-200nm) all world shrouded in dense fog cause O2 opaque to uvd!
Indeed! Perception of obstacles would seem to figure prominently among the 'advantages' of vision --- Though I'm bound to say I find it sad that your humor is to be lost upon all but, perhaps, a scant handful, of HPL enthusiasts...With xray and gamma ray vision we'd all be hopelessly lost in like Mr Lovecraft's _Walls of Eryx_!
I say that total kinetic and rest energies like you say _vested_ in mass in kgs system = (m*c^3)/(c^2-V^2)^0.5
You are correct -- however the relation is more elegantly (well... 'clearly') expressed thus:Sorry because not use formatting also only worked formula in head so maybe wrong?
I understand your meaning! -- Howbeit effective communication avoids pseudo-oxymorons and seeming-pseudo-oxymorons....K?...and V is relative for frame.
With some qualification the statement/notion that the rest energy 'vested' in matter is, in fact, the kinetic energy corollary to its temporal motion is both implicit in, and, I daresay, fundamental to SR -- (IOW Correct! -- Sort of...)So I say rest energy is kinetic energy from motion along unreckoned dimension? Maybe time?
In essence your idea is sound -- howbeit the value of such conversion is questionable owing to 'frame specificity'... On a flippant note: Ever ask directions only to hear distance denominated in temporal units? -- maybe the 'mooks' are way ahead of us!If yes then can nicely derive conversion between linear measure and temporal measure units!
I have thought about it over many years --- and while I suspect that such is indeed the case ---prepare to toss back a few more antihypertensives!--- I'd hate to have to prove it!!!Now I am saying if you think hard about it implication is intuitively obvious that _matter_ is just emr energy with wavelengths projected smaller than Planck length?
Oh... I think you understand it -- you merely don't like it -- On that - we're agreed!HP I don't understand why intelligent people insist on wearing blinders and refuse to think!
Only in academia is it cool to say "I don't know" -- the trouble arises when it really means (as it often does) "I should know but I'm too dim to be inspired and too lazy to educate myself" or, more succinctly, "I don't care" --- All of which is to say - We're agreed!All they say is _interesting ideas_ or _maybe_ or _not know_ and _too hard to think about_
Well... If they didn't genuinely feel you are exceptional, I doubt they'd care what you thought... That said, if they are habitually ducking questions or deferring to your judgement on the basis that you are better equipped to comprehend the subject than they -- such is miserably failed pedagogy at best and indolence onto cowardice at worst...I say when they brand me as _genius_ they think buying for themselves a lifetime pass to ignorance! They hope I take the genius nonsense seriously so maybe rest on my laurels and act lazy and unmotivated as they
Aye! -- And not merely "Tunnel thinking" but facultative 'tunnel thinking'!!! (Pun intended!)I say _Kalnienkmentia_ is academic way
My sentiments exactly! -- but with the qualification that there are more 'good apples' than you might think - really!Discipline is good but not when excuse for avoid big picture cuz too timid and childlike! So safely follow narratives of _sainted_ exponents of their field and liars for ulterior causes!
You've got it! -- I'll return to it early November at the latest -- that's a promise!Now I say the garret must be cooled off cause of weather so can resume fb tutorial? Is like therapy to me!
Be right HP! I holding my breath in anticipation!You've got it! -- I'll return to it early November at the latest -- that's a promise!
HP UR2 funny! I meaning bolding not quotes and bb code editor too much bother!@Aleph(0) if you closely examine your keyboard you'll notice two characters To wit: " and _ then there's a third 'character' (not on the keyboard but at it) who, for reasons unknown, substitutes the first with the second???
So... Use of the format bar is out of the question???and bb code editor too much bother!
If that's your 'strong suit' might I prevail upon you to retrieve my electron tubes???Be right HP! I holding my breath in anticipation!
No, wise a$$! Format bar has bugs so sometimes text gets screwed up so I need to use bb code editor anywaySo... Use of the format bar is out of the question???
I say seriously I would like to help if in just salt water but you know vast stretch of fresh water just creeps me out! Like I say unnatural! But you make hydrophobia joke!If that's your 'strong suit' might I prevail upon you to retrieve my electron tubes???
As, for instance 'stray' formatting directives that prevent 'de-emphisizing' or deleting to the previous line? --- I hear ya!Format bar has bugs so sometimes text gets screwed up so I need to use bb code editor anyway
And again, I assert that the 'uniqueness' (certainly not 'creepiness') of the St Lawrence system lays in its nascence! only 10,000 years! -- Wow!vast stretch of fresh water just creeps me out! Like I say unnatural!
That's a novelty!So here on topic questions
Succinctly: Convenience and insulation economy --- In such an arrangement the transformer core/case and the cable shields are at 0V=Gnd -- While the anode current indicator connects the windings' 'cold' ends -- As you pointed out in another post, said ends (and, hence, the indicator) are electrically bound to (near) ground by MOVs... The tube (a.k.a. 'insert') design/ratings reflect the intended power supply arrangement... --- FWIW Split secondary arrangements are common practice in many (especially line operated) EHT and, even, 'LV' applications (e.g. neon sign transformers, and, indeed, '120-0-120' residential 'pole pig' distribution transformers)plz explain why radiography tube maximum electrode volts to ground only 1/2 maximum anode to cathode volts?
Good move!Now spin RA to 377 radians/sec also preform like you say _seasoning_ for good gettering.
First off --- I don't recommend casually operating the tube at full rated EMF!!! By way of analogy, do you feel intentional operation of a machine at it's 'redline' AV is good practice???I intrigued because 75 pound dead animal totally translucent to 150kvp with long persistence fluoroscopic screen!
YES: Scatter activity in direct (while non-linear) proportion to photon energy is to be expected over the segment of spectrum with which you are working (playing?)Also scattering much increased above 120kvp so I ask is scatter just tem behavior or is pair production come into play?
What will go wrong now getered?First off --- I don't recommend casually operating the tube at full rated EMF!!!
I say less than 2/3 of mass in life cause mangled with tissue and blood loss by fatal trauma event so live mass probably 55kg round figures. Radiographed portion not crushed or eviscerated and no overt putrefaction so I say tissue condition close to living for radiography?Inasmuch as same is 'salvaged roadkill' it seems reasonable to inquire whether the carcass is intact? If not, then the organism's antemortum weight will have been greater than 75 LBS with corresponding 'heaver' osteology...
It was big cat for sure when I ask DNR warden permission to take remains he said mountain lion I like to say bobcat but not sure distinction I figure it killed just hours before I found it cause above ambient tissue temperature and was morning after cold night.While I'm not especially au fait with zoology, citation of the subject's species may be helpful
For learning ropes I wanted heterogeneous matter of same nature tube intended to transiluminate also very fun and interesting to practice bone and soft tissue imaging at lower kvp settings HP you know better than lecture me about aseptic technique! I know what I'm doing otherwise I'd have gone way of specimen years ago!Egads, woman! There are easier (and, I hasten to add, more sanitary) methods of exploring PE vs radiolucency characteristics! - as, for instance, ye olde 'fanned feeler gauge ploy'
HP I can't understand cause neutrino rest mass equivalent to energy like 30kev so means 60kev for pair but you're saying production need more than twice that energy? I understand how production by emr needs be indirect cause neutrino uncharged. So is it the indirect production needs energy higher than calculated?YES: Indirect lepton (Specifically electron neutrino) pair production becomes manifest at ~126 keV
That I totally understand! 1.022mev is sum of rest energy for electron and positron each 511kev! It's good when things make sense from get go Now I am asking how much KVP RA tubes really withstand? I say 150kv for just tube is like super conservative cuz of stator and electrical properties of heated glass?FWIW I'm guessing your real interest is in positron/electron pair production, which, as a practical matter (NPI), requires PEs > 1.022 meV ---- Readily attained (on the cheap) by Machlett DRT tubes...
I know distinction of emr and electrostatic phenomena!One solitary word about the 'Schwinger mechanism'
Suicide is not laughing matter! Now I refuse to encourage bad taste joke with reply!OBTW Further to this topic -- One solitary word about the 'Schwinger mechanism' and my LWT will be amended to stipulate that your legacy is contingent upon your personal performance of a 500 image series upon my remains following ten days exposure to scavenger-excluded tropical conditions subsequent to my auto-exsanguination -- Did I just make you cry? Yes? Well... not as fitfully as do I at the very thought of vapid bickering over irrelevancies!!!
Protracted operation of the filament (as for 'hard seasoning') is abusive of the tube -- moreover volatilized filament and anode material deposit on the envelope thus reducing the effective 'hold off' EMF... IOW significantly reduced tube life at best -- instant tube failure at worst --- with a new tube and impeccable adherence to prescribed gettering procedure - you will get away with maximum rated (and, for that matter, well above maximum rated) Anode EMF operation -- however tube life will be greatly reduced -- it's an example of 'to use it is to loose it' -- sorta like money!What will go wrong now getered?
So it would seem - even so I don't see the point? -- IOW it does not surprise me (in the least) that the described carcass is highly radiolucent to 150 keV (Yes! keV -- as opposed to kvp -- because a 'long persistence' [i.e. highly phosphorescent] fluoroscope is, in effect, 'peak reading')I say less than 2/3 of mass in life cause mangled with tissue and blood loss by fatal trauma event so live mass probably 55kg round figures. Radiographed portion not crushed or eviscerated and no overt putrefaction so I say tissue condition close to living for radiography?
Aren't you the legal beagle! -- Good move though! I've heard of stiff fines for collecting fallen feathers FWIW I believe a mountain lion is larger than a bobcat so... score another point for 'John Law'It was big cat for sure when I ask DNR warden permission to take remains he said mountain lion I like to say bobcat but not sure distinction
Fair enough!For learning ropes I wanted heterogeneous matter of same nature tube intended to transiluminate also very fun and interesting to practice bone and soft tissue imaging at lower kvp settings
Of course I do! --- I remind you, however, that despite appearances, you and I aren't the soul regular readers of this thread...HP you know better than lecture me about aseptic technique!...
--emphasis added--HP I can't understand cause neutrino rest mass equivalent to energy like 30kev so means 60kev for pair but you're saying production need more than twice that energy? I understand how production by emr needs be indirect cause neutrino uncharged. So is it the indirect production needs energy higher than calculated?
Typically Over 1.5MV if the envelope is not yet mirrored and the tube is 'seasoned' prior to each session via inductive heating of the anode --- many caveats apply! -- I will discuss it in detail if and only if you obtain another, expendable, tube! --- I will not be a party to destruction of your good tube on an impulse!Now I am asking how much KVP RA tubes really withstand?
And for all that you haven't yet mastered American English despite having lived here since your first birthday? -- Golly! Golly!!!I know distinction of emr and electrostatic phenomena!
I'm not a regular reader of this rather remarkable saga, although I do check in from time to time to see how it's progressing and to update my mental estimate of how long it will go on before it dies from sheer exhaustion. Right now it looks like you two are about half-finished with your discussion so I'm reckoning the thread will top out at around 300-400 posts. We will see.I remind you, however, that despite appearances, you and I aren't the soul regular readers of this thread...
Hey, at least she's not the one who misspelled "sole"...And for all that you haven't yet mastered American English despite having lived here since your first birthday? -- Golly! Golly!!!
LOL! -- My initial guess had it 'trailing off' following transfer of the tutorial to Projects ('scheduled' for next month) -- 'Tho I'm bound to say both of us have become accustomed (well, in my case, perhaps, 'inured') to the level of OT content seen here --- So I expect this thread's longevity is up to (and, for that matter, 'down to') Aleph -- That said, I definitely intend to post the tutorial to Projects - but with strict adherence to topic in the followup posts on that forum -- FWIW, my plans on this thread are to move ahead with development of the next tutorial in the 'EHT series'.... But again, as OP/TS, that's Aleph's call Personally It's become as 'home base' to meI'm not a regular reader of this rather remarkable saga, although I do check in from time to time to see how it's progressing and to update my mental estimate of how long it will go on before it dies from sheer exhaustion. Right now it looks like you two are about half-finished with your discussion so I'm reckoning the thread will top out at around 300-400 posts. We will see.
Alas! -- I need to invest heart and um... 'mind' in proof readingHey, at least she's not the one who misspelled "sole"...
Dear old Professor W. --- I am reminded of a line from Romeo and Juliet to the effect of "A gentleman that loves to hear himself talk, and will speak more in a minute than he will stand to in a month." (possible paraphrase) --- Wise man, the Bard!I tell Craig W. this he said he likes it but _shakes foundations of his life_
You overestimate them -- going insane (quietly or otherwise) requires some imagination --- They'd just fuel up the car (or advise me that the station was self-serve) sans batting an eyelashHP You gave me idea! Here's something for you to do so payback those like you say numpties Go to filling station to ask attendant how far to the town that is your states capital if they say stupid answer like 3 hours you say better fill er up! 1.74 billion miles on 1/4 tank is pressing my luck! My car aint no envirobuggy ya know! Then watch them go quietly insane
I find that particular species of ego-centric 'dullardism' straight up unendurable! As if their 'all high pronouncement' of transit time is universal, immutable fact! --- This is precisely the type of buffoonery often encountered when inquiring after a description but receiving only a 'review' of a subject's appearance -- For some reason (that escapes me at the moment) lackwits seem to think all the world shares their tastes, perspectives and sensibilities -- or, rather, that their perception is rooted in universal truth!if they say stupid answer like 3 hours
HP I say you're exactly right! If I trying to identify someone I couldn't care less how appealing or avant garde or chic or geeky or whatever someone else thinks they look! You right they think their tastes or biases and appetency shared by everyone! I say they're more ignorant and stupid than egocentric, after all it hard to be self centered when not much happening upstairs Now my turn to give you clue to interpret those _sheeple_ which is when they give their opinion like is fact they just passing along current narrative of mass media So like in Edgar Allen Poe's satire they are _little people in very big way_ or _big people in very small way_ What ever they are they have my contempt not cause limited intellect but cause they're followers! Now I say people who tell how long to get somewhere instead just how far are mostly pathetic cause that's only way they can think in their insular communal existence! Concept of real physical world frightens them! I should feel sad for emotional cowards but feel only disgust! Now I say genuine disclaimer! I detest just the followers and communal personality. I know smart people sometimes answer questions like that cause they're used to stupid questioners I say to anyone actually angered by my post that you have too much individuality to be who I meant to berate so plz rest in knowledge that you have blessing of the supreme Aleph!This is precisely the type of buffoonery often encountered when inquiring after a description but receiving only a 'review' of a subject's appearance
Well... It's hardly 'obscure', Aleph!HP plz remind me of name of big ghost town you visit in 2012? IIRC you said was industrial accident in 1985 so permanently evacuated? I can almost remember name only not quite and internet doing like you say 50% vs half dozen of nothing shillyshally on me
HP I understand what you mean about ghost towns serenely beautiful if can think on them without tragic history. 30 years seems like long time to me cuz more than my age but never will be long enough for those affectedYou are referring to a location/incident (1986) known widely as "Chernobyl" -- and, specifically, as regards my 'wanderings', to Pripyat
Well hey! --- Because I like your use of the term 'ghost town' -- I've scoured the web for this image:
HP you too worried about things like that! I caught it and moved on like you should have! Now since you're obsessing I say you should be careful about _qv_ cause you of all know they interpret that _quick visit_ in Duluth!I've corrected a rather nasty typo (near the 'top') of post #166 on this thread (q.v.) --- Although you seem to have 'seen through it', integrity (obsessiveness?) required correction and announcement of same
