Has to be said

Hi,
i been reading most sites and the little arguments about this and that about making audio in this case be more pleasent ot better to any individual. and have to say upfront that if "you" believe its better to you than it is in fact true to you and you only. we are just reletive respondants to each other and therefore nature and the universe.
many of the subjects that come up as to improving ones audio system tend to go into little details that may or may not have "real" affects on most of us. and also be provable with phsics,math,medical studies etc.many musicians and many humans can distinguish alot of these aspects. and they are ALL quantifiable and measureable very easilly. from 1800 till today FFT and resonance,sound perfiliration has been well adjustable from the totally acoustic pipe organs to the music halls 100s of years ago with out electronic fixes, and all these new snake oil gagets on the market. many are always big commenters here on this site.
Its totally true you can "fix" and sound wave with free rocks,walls,chambers, etc. so go for it at a cost of zero dollars. and adbandon all these marketing hacks.
Ive been well into sound,RF,Radioation, Electron manulipation, Audio,phsics etc all my life and all my relatives aslso . I dont need to justify my opinions yet am dignified by holding 8 international patents,2 doctrets and my dad with similar fields.
one crazy obvious thing no one even bothers to mention is the way off standard of 440hz shifted 8hz the earths standard resonance. while all the 1000s of years 432hz was based on real natural happenings before electronics. dont you all care everything you listen to is 8hz off tune and therefore wrong, but you will bicker about a few microvolts noise from an ocslittating wire with parallell wire  hanging off a standoff. itf too funny to me.
yes all digital except one source tunes their DAC math to 435hz to be more correct to Verdi and other great composers.
ive got tuning forks over the audio and above spectrum and tune my panios violins etc to them 432 hz
and need to say again. yes please do everything Analoge
to correct your sound system, its been done in churches,music halls,the great pyrmids, with instruments themselves.
but do not chase the rabbit down the money hole to fix apparent physhoacoustics in your listening area.

ps the spelling and writing is horrid cause ive got a brain injury2 years ago and under go EEG,ehthesographs and neuro studies constantly. where various frequency sweeps are put thru me and studied by the medical and commercial fields.
Im off for now to play my bass thru 50000watts total. and resonate the neighborhood at 8.2 HZ....

Forest for the Trees has a whole website devoted to his alternate universe. A world of Morphic Fields ruled by the Nimbus Sub Hertz Platform, the Firestone 16-wheeler air bag, springs, and rocks.

I worry you think I might be kidding. http://www.machinadynamica.com/machina24.htm

Yes teleportation. For only several hundred dollars he will call you on the phone and wherever you are in the world you will hear your system improve all thanks to his telepathic use of pebbles, er I mean W.C. er I mean Morphic Fields.

Forest for the Trees occasionally makes the mistake of trying to disembowel me. What looks like a sword to you looks like word salad to me. If there were any sense to be made of it I would let you know. Like the CD thing. He got that right. Give the man credit. Anything else? Let you know when I find it. Don’t hold your breath.

Forest for the Trees loves to quote physicist Feynman. But notice its always the quote meant to put you in your place. If I could explain it to you it wouldn’t be worth the Nobel Prize. Uses that one so much he has it all ready to cut and paste. At least I figure that has to be it. Because when I cut and paste *his version* into a browser all that comes up are his posts. Its never what Feynman actually said, which is worded a bit differently. More to the point, its contrary to another thing Feynman said, that if you really understand then you can explain it to anyone. Feynman’s famous for being able to explain the most complicated puzzles in a way that just about anyone can understand.

>>>>>You get so emotional 😭 Your non-stop ranting perfectly highlights the problem that Einstein and Feynman and others oft experienced when trying to explain their theories to the average Joe Blow on the street. They sometimes met with extremely rude and Neanderthal reactions. That’s why Einstein’s most iconic photo shows him sticking his tongue out to reporters. 😛 There is very blurry line between Classical physics and quantum mechanics any more. My advice would be relax and enjoy the ride. 

I’m not trying to set the world on fire, just start a flame in a few hearts. 💕

A  simple apology to "clearthink" instead of deleting your post would have been sufficient. And by the way, I don't report offensive posts to the mods. Well, with the exception of one, which was a snarky, insulting post directed toward me that revealed personal information by a member other than you.

  • "If you can’t keep up, don’t insult others. Just because you have to run to Wikipedia to understand the words being used, does not mean that others do."

Yes, atdavid ... it must be a real chore for you, in your gloriously superior, self-important mindset, to associate with us, the great unwashed, here on A'gon.

<Sheesh!>

The second way x-rays are produced is result of the moving Cathode electron penetrating deep inside the glass atom — and hitting the the atom’s tiny nucleus.

They're not paying me anywhere near enough for this. But as an X-ray tech I just can't let the lunacy go on without at least trying to set the record straight. Every once in a while a sane person comes along and so this way at least there'll be something worth reading.

The only glass involved in the production of x-rays is the glass vacuum tube. Electrons generated by a filament (much like a light bulb) at the cathode end stream across the tube at high speed, because being electrons they are negative and strongly attracted to the positively charged anode end. The voltages involved are all in the kilovolts, typically 120kV for a chest x-ray, and the tube is a vacuum, so the electrons get going pretty damn fast.

At the anode end is a target. Both the target and the filament are made of tungsten, used because its high atomic number means it has a lot of electrons, which is really important as you will soon see. Its also metal, malleable, heat resistant, etc etc. 

So electrons go streaming across the tube so fast they hit the tungsten at the other end with so much energy they start a whole chain of reactions, chiefly bremsstrahlung, German (since it was Germans who discovered this) for "braking". Much like the brakes on a race car get hot and glow red radiating braking energy, the tungsten gets hot and glows x-rays.

The reaction we are mainly concerned with here happens in the electron shell. Collision energy causes electrons in one shell to increase in energy to the next higher level shell. Think of it as pushing them into a higher orbit. But electrons in their shells balance protons in the nucleus, so this is an unstable situation. But to fall back where it "belongs" is a lower energy state and so to balance the equation the tungsten atom releases a photon. A very high energy photon we call an x-ray.

This is actually pretty basic 100 level physics. Okay I'm old, grade inflation, call it 200 level now. Whatever. Point is, you got a guy pretending to be a physicist, can't get it right even about something this basic.

And he's actually pretty  good compared to the other one.

Oh, I'm always saying DYODD so....
