Well America's shrinking influence is taking care of that with 20% control of the global economy. China, like Japan and South Korea, practiced mercantilist economic policies in the past, with America looking the other way for cold war reasons. How ever since the cold war, the international situation has changed considerably, America loosening its strangled hold over South America and Central America for instance.

I am still confused. Which of the two?

Well, we have our own lithium and other shit and Niron magnets promise to be not only stronger than rare earth magnets, but easier to work with and allow new possibilities, cheaper too. Also new mining and processing technologies are opening up new sources of lithium and new electrochemistry's might make lithium moot anyway. They can compete making LED lightbulbs, wiring harnesses and interior panels with South Korea and southeast Asia, in a more diversified and flexible supply chain. Removing the vulnerabilities in the chip and electronic component industries is a no brainer in today's world, automation makes onshoring these industries feasible. China and other countries dump tens of billions into the capital-intensive chip industry, so Uncle Sam has to too.

Not America, that's history, today's issue is China, they are an adversary, not an enemy like Russia, but they will bully and punish other countries when they are able to for speaking the truth about them. They are not somebody you would want to have power over you, as Russia might find out in the future, going to Xi on your knees is a sign of weakness.

With my neurological condition I could not play guitar as it hurt my arm and where it contacted my body. Found out that I can play (play? Hah! Still need to learn my first tune), that is practice, using a Stratocaster type guitar with the arm and body bevels. So I have a goal, build a practice guitar that is light weight. Did that and I have a Telecaster with the bevels which is all made of spruce and the body chambered to shed even a few more oz's. But darn it I want an acoustic to practice with.

I won't go through all the pictures, made the body out of spruce and bent the top for an arm bevel.



Got the box closed up and took a saw to the belly cut area.



glued in some kerfed lining and shaped it into a pleasing shape. Then I bent a section of the top I cut off. Multiple compound curves, I am surprised it all worked out. Just need it to set for the night and tomorrow I will try to figure out how to glue it on.



Will be happy to see the box finished so I can start cleaning up (You mean everyone does not work on the last six inches of the bench?) and start on the neck.



I will be updating my progress in a couple of the guitar building forums I am on tomorrow once I glue the last piece on but I just had to post it somewhere as I did not know I could pull off making this piece. Nobody does things like this as it is very troublesome, I was unsure If I could. Still a long way to go but but nothing I have not done before.

what they haven’t shown is the generation of durable matter. Selectively ditching the antiparticle is gonna be the hard part.

A similar phenomenon occurs in what are called pair-instability supernovae. The energy density (photon gas pressure) gets high enough for a second or two.

Used to be a bit of a geek (no really) and watched a lot of shows on astronomy and sub-nuclear investigations. Seems that in empty space a particle can pop up, stick around for a really short while and then disappear again. Did it come out of nothing or did it just slip from one dimension into ours and then back from where it came? Did they create matter from energy or did they just trap a particle from somewhere else? What is reality? Things were so simple when I was a kid.

1) the paradox: the zero-point energy is nonzero.
2) yup.

I remember reading it in a general science book decades ago, George Gamow? Photons are supposed to be massless, but energy and mass are interchangeable, though most of the mass loss is probably neutrons. It was in the process of detonation of a thermonuclear weapon.

I thought of reality and the nature of the cosmos and solved the whole big bang thing but the concept slipped away. Hard to hang onto anything really complex when you are high. Actually happened more than once I looked behind the curtain of reality and things became clear. Then lost it.

I’ve had similar experiences on psychedelics and dissociants. I remember being shown the underside of reality.

My neural mass loss is becoming of consequence.

I’m guessing you mean neutrinos. I blame the spell chicken.

Nope, but here is a reference:

At the temperatures achievable in the fission core of the primary (up to 10^8 degrees K) nearly all of the energy is present as a thermal radiation field (up to 95%) with average photon energies around 10 KeV (moderately energetic X-rays). Most of this thermal energy is rapidly radiated away from the surface of the "X-ray fireball", composed of the expanding X-ray opaque material of the core and tamper. It is this powerful flux of energy in the form of X-rays that is harnessed to compress the fusion fuel.

We're taking over, America is being invaded from the north as well and by varmints! Canada's answer to climate change and drought, resistance to our rat is futile! They can cleverly get by the border patrol too...
