I like my LCD 15" monitor, but after a while one should change focus field and stretch the body. I accomplish this by chainsawing, loppering, etc.

Thank you, Bascule. I ponder.

Trying to see the sense here, if the coincidence rate falls less slowly than it should with increasing theta, is this relatively larger coincidence what we refer to as not locally explainable by separate statistics on the two states?

cosmologic plasma recombination
Norman Albers replied to Norman Albers's topic in Astronomy and Cosmology
I see a limit to the usefulness of the term "phase", or "phase state", when describing electrons as energy. When we experience materials changing mechanical phase, we deal with ensembles of particular constituents. When we speak of radiation "condensing" into particle pairs, the constituents are photons which have no preferred size. The unique size of the electron speaks of the fundamental coupling constants and its geometry. We are left, as the cosmos cools, with electrons and light, but the light is cooling in average frequency. This does not happen with water and ice! Maybe with ice and vapor? -
If the circularly polarized photon is passed through a plane-polarizing filter, do we get half a chance of a plane wave being transmitted? If so, was there angular momentum given to the filter?

Nice system, makes me nostalgic for my BMW R-600 motorcycle, which I gave up after getting piano tuning tools and appointments (thirty years ago). Don't high speed rail cars do a similar swing so diners don't? I never thought about the old motocycle sidecars' suspension; were they pivoted at least so the driver can lean?

Very cool concept of this zippy little three-wheeler. Is it an hydraulically active suspension tilt that counteracts the otherwise tipping instability of tricycles???

Scientists produce 2 billion degrees Celsius
Norman Albers replied to wormholeman's topic in Modern and Theoretical Physics
Ragib, I only poked a little fun at toaster wires but you showed you understood they vaporized. I should not dismiss the role of resistive heating because that is what happens first and continues as long as the current path is there. I appreciate your discussion, and though I spent two years as a college research assistant on an accelerator team at the Brookhaven 3GEV beam, I don't know much theory here. I observe we have a factor of 5 or so higher temperature than mentioned for carbon 'burning'. Water is one thousand kg/m3; steel is maybe 5-6 times as dense, and however much the volume is pinched, perhaps a factor of a thousand, multiplies in. If it is true that what matters is the product of temperature and density (given adequate energy), it seems to me on an order-of-magnitude quick approx, we are only an order of magnitude shy. -
Could magnetism just be explained as a relativistic effect ?
Norman Albers replied to sally's topic in Speculations
This indeed works but there is less here than meets the eye. I am not saying it is not useful, though. The trick we are pulling off is in picking out transverse components of relative velocity. Refer back to my statement about how we construct the integral of magnetic vector potential, in panel #37. There it is manifestly clear that we are dealing with interaction of two currents related to their vector dot product. -

Steel is iron and some carbon and small amounts of other possible additions. I recall that iron is at the center of the "nuclear periodic table" in the sense that both fission and fusion stop here. There is no further energy to be found. Any reactions would involve carbon or anything else in this soup. Remember that carbon takes part in the later fusion cycles in stars. Can we rule out the presence of hydrogen? Is the experiment in vacuum and is there no significant presence of hydrogen? . . . . . . . . . . Checking Wikipedia for 'carbon burning': "The carbon burning process is a nuclear fusion reaction that occurs in massive stars (at least 4 MSun at birth) that have used up the lighter elements in their cores. It requires high temperatures (6×108 K) and densities (about 2×108 kg/m3)". We are dealing with enough kinetic energy (temperature) so some amount of fusion should be expected, depending upon density. -

Norman Albers replied to wormholeman's topic in Modern and Theoretical Physics
I am simply talking shop. You say nuclear reaction requires force and I disagree. It requires energy to overcome reaction thresholds. In controlled fusion we heat the plasma to the point that protons hit each other sufficiently hard to fuse. In fission we assemble enough atoms in proximity that random neutron emissions stimulate chain reaction. Forces involved are incidental: slamming together fragments of the critical mass (not needed in a reactor), or confining a plasma (relevant in z-pinch and in tokomak machines, but not in the multiple laser approach). -

Norman Albers replied to wormholeman's topic in Modern and Theoretical Physics
Excellent, Ragib. Do we expect no nuclear reactions here? If temperature is 2 billion degrees, say, average energy is 200,000 EV, and we are looking at ion temperatures sustaining this for a surprising number of nanoseconds. The mass-energy of electrons is twice the typical gamma energy being seen here, or 0.511 MEV. -
Sorry, I was thinking too loosely and shall try to put such thoughts into SPECULATIVE posts. What I read to date seems to say that coincidence in two detectors decreases more slowly than it should, as a function of relative angle of polarization. Is this what we consider non-locality?
-
My thesis is that the radiation field contains also a population of fragment levels of disturbance. Can we find further understanding to this problem by saying that what propagates are the two entangled states and their reaction in the background field? If this could change the statistics of polarization between detectors we'd be onto something good.

How long does the wire last? Don't forget there is a strong z-pinch going on, where the axial current pulls moving charges inward. This is more than a toaster. -
I got things backward, above. Quantum mechanics predicts dependence of the square of the cosine, while Bell's theorem (which fails) says it should not be stronger than linear dependence on angle. Squaring the cosine expansion still yields a square term.

Interesting observation about the oil viscosity! Clearly we are servicing a low-stress engine, and I read last year that oil additives had been created to do a stress-linking response that only kicks in at around 15 gigaPascals. In these small engines, there was not enough stress and they have had to lower this threshold.

For a holiday treat, bake cheese-stuffed jalapenos, cored of seeds of course. A Mexican-American guy recently observed that in general the seeds are too hot and can lodge in the gut. Sinsemilla is useful here, too.

Is there any out-of-doors? (I love that term.) I recall reading that the manifold of spacetime is 'unbounded'. What of this? Can things be finite yet unbounded? In a wraparound topology you can come back in on the far side of the 'screen'. Which of these concepts is still possibly part of solutions?

Norman Albers replied to sally's topic in Speculations
I predict there will be not so much new found here. We are used to constructing the vector potential field, 'A', as a straightforward image of the current source divided by 'r'. One can in only one further step, construct an energy term of [math]j\cdot{A}[/math]. [Where are latex vector notes?] -
Chilis seem to be one of the most universal crops, as every region has proudly their own. Every different valley in Hungary has its own paprika, etc. How cool that you partake in this culture a la WWW. One day I walked into me beloved Mexican Restaurante in midafternoon. Emilio sat with a friend over plates, but his forehead was swollen, his eyes bugged and weeping, and it generally looked like some kind of crisis. I said, "Necessitamos una ambulancia???" He gasped, "Oh, no, it's......good" and then I saw the stems of a large habanero on each of their plates. I AM IMPRESSED.

We had friends over for a chili cookoff, and one guy made his on my stove: two habaneros, a few jalapenos, pasillas, reds and yellows, and yes, beans. I don't recall if he used gloves, but repeating this later I sure wished I had! The backs of my fingers stung for an hour. Anyway, he slow-cooked these for a half-day and we actually ate them the next. All I can say is that it was deeply warm without burning, and gave an amazing nuclear critical mass feeling in my stomach. None of this, nor the fallout the next day, was anything but pleasant. NUCLEAR BEANS and eat rice and tortillas also. . . . . . WISDOM OF THE PEOPLE: tumeric, part of most curry mixes, killed most prostate cancer cells when shaken in a test tube. Someone noticed that salsa kills a meat Salmonella, and traced it to cilantro leaves containing dodecanol. Whoa, if the gringos do not eat salsa in Mexico, they get EL REVENGE DE MONTEZUMA.

How much more does heat cost compared to air conditioning?

You have a semi-leaky and highly intelligent brain.
