I'm only writing this for those who may appreciate a clarification on Donaire's formulation ( http://qvg2013.sciencesconf.org/conference/qvg2013/program/Donaire_qvg2013.pdf ).Donaire explcitly requires a helical (chiral) anisotropic third order tensor (epsilon ijk) as shown in this attachment:gamma is an antisymmetric T-P odd tensor resulting from the anisotropic product of epsilon ijk with the magnetic field B(The word helical of course has multiple connotations, and this clarification only refers to how Donaire uses it)helical:

Then plug his book.I am most familiar with Woodward's work because I dispensed with all the competition almost 10 years ago for good reasons. When someone makes a claim about Woodward or anyone else's work that I know is false, I simply post about it. It was in the context of the discussion. And I did not plug his book.BTW, have you read it?

Spectral non-reciprocity is needed: Yes, that is the condition you will get from the "coffee can" resonator in an AFR.From what I can gather reading the rest and trying to apply it to the cavity, it should be treated as a single quantum "oscillator" w/ the conduction electron bands providing the Doppler shift required.Spectral non-reciprocity is as far as I've gotten on a GR basis.

Sounds like broken symmetry to me but I wasn't sure. I didn't quite get what they were meaning by that. Also what is an AFR? There is a lot in that presentation that I didn't quite understand.
With respect guys.Like my pc this thread needs to restart now

You know, that looks an awfully lot like orbital angular momentum.
Next batch of scraped data from figure 19 page 15 of "anomalous thrust..." from Brady et al. The top (result1.txt) and middle (result2.txt) graphs are scraped. Same caveats as previously posted. For first curve (top figure 19) I removed the (non existent) flat last sampled data of the previous version to avoid artefacts when analysing with filters.Each line of those files is the value in µN at each .1 s interval (linearly interpolated from manual reconstruction). The vertical scale were roughly given by the calibration pulses at about 30µN (expect no more than 5% precision). Absolute values are arbitrary (because of the drifting baseline). Horizontal scale given by the indication of 196 s for the whole display graph window of the pictures.Will proceed with other graphs when time permits. Will post attempts at original signal reconstruction : thrust(t) while what we see is only balance displacement(t). Since the balance is underdamped, a lot can hide behind those oscillations and drifts in position.
Well Brady "A" and Brady "B" truncated cone results can be explained by drifting frequency away from amplitude due to the extremely small bandwidth associated with high Q and their lack of suitable equipment as proposed by R. Ludwick
