Please refer back to response #26.
ooops.....My error. You are correct, I read the article at the beginning just now. It does say relativistic. My response was to the OP question and was only trying to help him.
Quantum Physics it is. Not my thing. I get it finally, I can't talk quantum and...
You didn't specify relativistic speeds. We were talking about Solar Wind (~ 1 million miles per hour). Not near the speed of light. Is this forum only for quantum physics, or is classical everyday physics allowed?
Perhaps I misunderstood.
I hope I'm using "quote" correctly, if not please give guidance....
Are you asking if the curved path intrinsically reduces energy vs. a straight path?
Otherwise, yes even photons can alter an electron's energy state markedly, it doesn't have to be another particle of matter.
In the above post, the OP said:
"As I inferred implied moments ago, I've studied electron beam deflection in a cyclotron. Your video doesn't make me understand anything more perfectly, as it's basically the same thing. "
If you've studied cyclotron theory, you know that electrons...
You asked: "Milliohms? :bugeye: Do you have a way of testing these resistors? I'm guessing a wheatstone bridge?"
Yes right on. a guarded Wheastone bridge bu ESI for high resistances up to 12,000 MegOhms, and an ESI Kelvin Bridge for the very low stuff (old tech but accurate), also a pair of...
Help me out here, I'm a little confused. Someone posted this link in this thread earlier:
Inside is a video with this caption:

ESI was merged several times, the main survivor today of the corporate takeovers is IET Labs.
Accuracy when Tegam made them =
Resistance Increments See Table 1
Initial (0.01% + 7 milliohms)
Long-term (0.02% + 10 milliohms)...
I'm no scholar but we do use silicon and germanium detectors in the radiation detection lab. Most of those must be operated in total darkness, because they also respond to visible light, as they are actually photocell technology.
If you are the OP and this seems like something you might be...
That makes sense. Thank you. If the nucleons were separated totally and not bound in another, lighter set of nuclei would those free nucleons (protons, neutrons) weigh more or less than the original massive nucleus?
So the tightly bound, massive nucleus undergoes fission (either induced or spontaneous SF), the nucleons are separated, thus weighing more than the did when bound (correct?) and the difference in that weight is the source of energy? So in E=mc^2 in the frame of fission, the m=mass...
OK Thank you. I have lived with the same confusion for decades.
I will go on assuming that if the mass is deficit, then the energy is deficit and the relationship is they are the same thing.
The missing negative sign was really confusing me.
thanks for your patience.
This may not have a bearing on your incident, but I owned the company that installed video cameras in nuke facilities, and we had a bad problem with 1) radiation turning the lenses brown, and 2) the electronics going crazy. Problem was the cameras were held in a hot cell for quarantine before we...
Electro Scientific Industries, ESI- DekaStat, DekaPot, DekaVider series. Most are Kelvin-Varley resistive dividers. This one pictured is a simple adjustable resistor I just finished restoring this year.Beautiful.inside and out, all wire wound resistors using non inductive Ayrton-Perry wiring...

Summary: Electron-Positron Annihilation, low energy vs high energy mode- do both end in 511 keV Annihilation? ANSWERED!
From the friendly folks at Berkeley/ DOE National Lab:
No sir, I am not meaning to do that. I am asking the question, and the real answer has ramifications at every level of science, particularly astro-physics where these high energy phenomenon are common place.
Obviously we agree that the e and p are carriers of induced kinetic energy. Their rest...
Thank you for your kind reply. So you are saying the added kinetic energy somehow goes through the annihilation? Would not two negatrons (negative electrons) with the same kinetic energy also shed that energy in a collision and produce similar results without mentioning the concept of antimatter...
I agree. Radioactive Iodine is commonly used in many industries, medical, and geophysical surveys, even water well and waste water injection wells. The sources are many and involve different isotopes of iodine but the decay photons will give the answer right away. That is common nuclear...
"An e+ and an e- moving in the same direction with .99 c wrt the lab annihilate happily; the photons will not be back to back in the lab and have a combined energy of 7.24 keV . "
Please rephrase this quote and correct if if you see fit. As it is written I can't understand it.
No radiation would be detected at a distance really. Radioactive MATERIALS (especially gas ones) could leak out and be carried by the wind to other locations, where they subsequently go though nuclear decay and then the radioactivity from that decay would be detected.
But we don't know if this...
Sure, I'll be back in 10 or so minutes with links, citations, and exceprts. Meanwhile, ponder on why positronium can exist.Hint: it's to allow excess kinetic enegy to be shed by interaction with other particles, to prepare for e-p annihilation. This is known as the low energy mode and is the...
