Standing Wave Pattern (SWR) and Propagation in Lossy Medium
This animation serves as complementary to a previously uploaded one ( http://www.youtube.com/watch?v=s5MBno0PZjE ) where the medium was lossless. This time, the medium onto which the wave is impinging is lossy and we demonstrate the time-domain propagation…

In hotrodding the use of acoustic longitudinal waves to provide compression of air volume and greater cylinder fill has been used since early 1930s to produce a great air displacement than a static model. In the 1980-90s at GM we used this knowledge to make a 305ci engine perform as well as a 350ci engine further modification from the mass production allowed tuners to make 30-40% gains in volumetric efficiency. Later Ford then asia produced similar designs in the great long runner engines of the day the characteristic howl of the intake on performance engines was due to the use of this technology. Luxury vehicles used this technology but also used noise suppression on the intake air filter assembles lowering effectiveness as much as 50%. Simply removing most of the plastic components of modern engines noise suppression systems can improve fuel and performance by 20-30% on average.
I have an engine originally from a 1995 Chevy Caprice Police car the base engine was 9:1 compression 350CI produced 275HP from factory at flywheel. By installing stronger pistons that come slightly higher in the cylinder it increased compression to 10.5 : 1 producing 320HP. By cutting the cylinder heads at an angle from 23 degrees to 18 degrees it reduced the compression chamber to 54 CC. Increasing compression to 11.5:1 increasing power to 375HP. By machining the intake ports to 220CC and porting the intake runners to lower the resonant frequency it lowered the torque band to 1500rpm from 2800rpm. Adding chromium silicon low tension low inertial mass valve springs and placing return springs on the lifters it raised the effective rpm range to 9000 rpm from a peek of 5800. The engine produces 600HP without a compressor or turbo. This engine sounds like a motorcycle engine rapidly increasing RPM.
On my wifes car we have a 3L Mitsubishi 24 valve engine with similar modifications from factory it produced 175HP now it produces a little over 300HP.
My 2002 Cadillac Seville has a 4.9L Northstar again similar modifications produces 575HP.
MY truck has Brodix 500CI Small Block Chevy with 750HP.
Comprehending the nature of compressive waves in literally acoustically tuning engines has been a hobby of mine for years, again it is all about the energy of sound.

By now the sense of RIGHT has been transformed and manipulated into something that is exactly the opposite and is not at all right, logical and balanced.
There are those around who profess to go and embrace the demons and monsters who have harmed us in infinite ways and in infinite times to arrive at peace.
And they also say that we should become ONE with them.
Sorry, what?? Did I get it right?
And would that be right?
Does that sound fair?
Not at all and IT WILL NEVER HAPPEN.
The true balance of right surely isn't to embrace murderers and rapists and cannibals and all those fucking freaks, and forgive them without consequence.
They would like it to happen ;)
And if they think that it will be enough for them to distract us and lie to us to make us forget the harm they have done to us, they are very wrong.
WE DO NOT FORGET.
It's impossible for us because our scars are too deep, and it's thanks to those monsters that we remember them :)
EVERYONE will have exactly what they gave and sowed, nothing more, nothing less, ONLY WHAT IS RIGHT.
Nobody is excluded.
The time of injustice has passed.
The universe is in charge and one way or another it will do what it has always done.
RETURNING ORDER TO CHAOS.
And it will do it in his own ways and times, not ours.
After the consequences, the time for forgiveness will also come for those who remain and for those who want, but not before.
YOU CAN NO LONGER RUN AWAY FROM YOURSELF DEMON, YOUR MONSTERS ARE COMING TO GET YOU.
Have fun ;)

I consider that Satan could be our "local" god. Could offer Jesus the world because it was his to do so.
A distant creator God, impartial at the center of reality makes sense to me. Or even a dead God who died to create the universe, sort of the big bang but as a explosion of consciousness. God forms and then explodes, kinda thing.
Idk. But whoever is managing this world is doing things as intended with little push back.

Good read from John Michael Greer. I don't think people on this side know what will happen demographically after the long decline. I believe it's a race between displacing white populations quickly before the decline fully sets it.
"The problem with this scheme is the same difficulty faced by all Ponzi schemes, which is that sooner or later you run out of suckers to draw in. That happened not long after the turn of the millennium, and along with other factors—notably the peaking of global conventional petroleum production—it led to the financial crisis of 2008-2010. I don’t imagine it’s escaped the attention of my readers that since 2010 the United States has been lurching from one crisis to another. That’s not accidental. The wealth pump that kept the United States at the top of the global pyramid has been sputtering as a growing number of nations have found ways to keep a larger share of their own wealth. The one question left, as I noted back in the day, is how soon the pump would start to fail altogether."

How is anyone doing well to take responsibility in this world? You're asking to be homeless and persecuted.
The world is a joke. It is beautiful perhaps but the system is slavery. The religions are slavery. Etc.
We are all living in sin, but who cares at this point. The world is boiling, jabs, wars, chemicals, corrupt society, perversions.. onwards and onwards.
To learn some lesson?
If my father did these things in this realm to "teach me a lesson" we'd have no relationship. That's allowing an abusive person, or abusive diety too much space in your life.
In context of our local realm, with none of these fantastic esoteric or empcoe ideas..
Whomever is in charge here is an asshole.
