  1. A data structure is created in a database to store and query the data from a program in the most efficient/effective way. The structure of the data is modeled in various ways. https://en.wikipedia.org/wiki/Relational_database One example of a programs data structure is an Entity Relationship diagram. There are many other ways to model data structures including Data Structure Diagrams, Data Flow Diagrams and NIAM for object oriented projects. The best method for modelling data structures depends on the nature of the data and many of the above methods can be used in conjunction with each other. https://en.wikipedia.org/wiki/Entity–relationship_model https://en.wikipedia.org/wiki/Data_structure_diagram https://en.wikipedia.org/wiki/Data-flow_diagram https://en.wikipedia.org/wiki/Object-role_modeling
  2. It looks like the paper was written by a marketing person or somebody who doesn't know much about job matching systems. I designed a Competency Management System and developed software as a proof of concept in the mid 90's. I later worked for a company that provided Competency Based training services for the international mining industry and adapted the Competency Management System to extract data from the companies Competency database in the early 2000's. What they describe is a elementary job matching system (Figures 1 and 2 in the pdf) that only links one candidate to one job, which has no facilities to determine Training Needs Analysis or even produce a list of jobs that one candidate is competent for, and describe these deficiencies as a 'feature'.
  3. It seems that there is a relationship between SR and QM that you may have overlooked. My original reference was "Relativistic QM uses Lorentz transformations which are also applicable to SR i.e. the calculus is the same." I came across this recent publication that highlights aspects of the historic and ongoing development of QM that give insights into to many of the weirdness issues and my concerns, as discussed in the original thread. Kronz, Fred and Lupher, Tracy, "Quantum Theory and Mathematical Rigor", The Stanford Encyclopedia of Philosophy (Fall 2019 Edition), Edward N. Zalta (ed.). My prior reference to SR was with respect to the diagram of an SR based "optical appearance" plot that shows both the straight line and spiral/wave nature of in-transit photons, emitted from rotating/orbiting sources to a relatively stationary observer over one complete rotation/orbit, that are present at the discrete time and location of the observation. https://plato.stanford.edu/entries/qt-nvd/ While QFT doesn't take gravity into account it is still an import part of QM. Further, the "Quantum Theory and Mathematical Rigor" article also includes references to QM that do not exclude "improper functions", particularly derivations based on the Dirac δ function such as rigged Hilbert spaces. The mathematically rigorous foundation is mainly with regards to the self-contradictory properties as identified by von Neumann above, so my original point about "improper integrals" is valid on the higher structural level of symmetries. As I have said before on other threads, IMO these issues and the 2*pi matter ratio artifact only impact the higher universal sum calculations and do not generally interfere with QM below this level of abstraction.
  4. So the only real repeatable aspect of dark matter is that (Universal dark matter + Universal ordinary matter)/(ordinary matter) = (28.5% + 4.82%)/4.82% = 2 * Pi +/- 1.1%, as calculated by LambdaCDM via both the WMAP and PLANCK data, but that is not weirdness? https://en.wikipedia.org/wiki/Planck_(spacecraft)#2013_data_release I agree entirely, it is the only non weird fact about universal dark matter that we know about with any certainty.
  5. Corrections? The diagram I posted, that shows the two states of weirdness together in the one model, i.e. the consolidated spiral pathways of straight line in transit photons emitted from rotating/orbiting sources over time, is based on an SR 'optical appearance' plot not GR. Another weirdness is the difference between the reduced Compton wavelength (lambda_bar) used in quantum matter (LambdaCDM universal matter) and the standard Compton wavelength (lambda) used in calculating observed universal matter, which also equals 2*Pi. https://en.wikipedia.org/wiki/Compton_wavelength#Distinction_between_reduced_and_non-reduced 2*Pi is not very far away regardless of the type of quantum weirdness.
  6. Relativistic QM uses Lorentz transformations which are also applicable to SR i.e. the calculus is the same. https://en.wikipedia.org/wiki/Symmetry_in_quantum_mechanics https://en.wikipedia.org/wiki/Noether's_theorem
  7. That was only the first part. If the observer is stationary relative to the center of rotation/orbit of the sources, the sources continue to rotate/orbit and emit for 1 complete rotation, and the photon path is not distorted or blocked, there will be a discrete spiral line of photons stretching from the observer to the emission source at the time and location of the observation. And the calculus it uses?
  8. I suppose you could call it first degree Quantum weirdness when most people are aware that 1/ the photons/wavelengths that are emitted from all the rotating sources in the universe 2/ travel in straight lines from their emission point to the relatively stationary observer 3/ although they are not generally aware that the source and observer are connected by a discrete spiral photon/wavelength path at the time and point of observation, if the source is still rotating and emitting and the path has not been blocked or distorted along the way. The second degree of Quantum weirdness is that people who aren't aware of both the straight line and spiral paths of virtually all observed or in transit universal photons/wavelengths 1/ call the ratio of Total Calculated Universal Matter/Total Observed Visible Universal Matter numerology 2/ even though it equals 2*Pi +/- 1.1% for both the WMAP and PLANCK data using the Lambda CDM model. I also suppose it is a consequence of the symmetry of the calculus of improper power functions, as proved by Emmy Noether, where piecewise continuous integrals with limits from +infinity to -infinity (that don't converge), could be considered as valid improper power integrals, if they were considered a sub function of a higher level function of (at most) 1 rotation (i.e. 2*Pi). https://arxiv.org/abs/physics/9807044v2
  9. The latest data from John Hopkins shows the rate of Confirmed Infections/Recoveries to be 37.04% (Confirmed: 80,994, Deaths: 2760, Recovered: 30,000).
  10. That may be the case for China but other area's may have their own separate peaks depending on their respective containment activities. I went to a Medical Center and a Chemist today and both had signs asking people who had a fever/cough and who had been to China in the past 14 days to contact the staff immediately on entry. The John Hopkins University Data shows Total Confirmed: 80,147, total Deaths: 2,699, Total Recovered: 27,657 and the ratio of Recovered/Confirmed is currently 34.51%.
  11. Don't forget government guarantees for deposits (including structured products, managed funds and bonds) up to $250,000 in banks etc (including many foreign institutions), like in Australia. https://www.apra.gov.au/financial-claims-scheme-0
  12. At least it will cause no harm, depending on what was mixed with it that is.
  13. https://www.asbmb.org/asbmb-today/science/020620/could-an-old-malaria-drug-help-fight-the-new-coron
  14. Yes CharonY, 4 of the Confirmed Infected cases in Australia who recovered were treated with paracetamol. Tonic Water would probably help in those milder cases as well due to the Quinine. The current John Hopkins University figures are: Total Confirmed: 75,727, Total Deaths: 2,128, Total Recovered: 16,447 and the ratio of Total Recovered/Confirmed is 21.72%.
  15. There are many different types of Flu like viruses transmitted by bats/flying foxes/fruit bats and many of the transmission vectors are not very well understood, particularly for things like the Hendra Virus, which has a much higher human death rate than Coronavirus. I wouldn't rule anything out at present. https://en.wikipedia.org/wiki/Henipavirus#Hendra_virus https://en.wikipedia.org/wiki/Henipavirus https://www.abc.net.au/radionational/programs/backgroundbriefing/outbreak-at-victory-lodge/3564868#transcript
