  1. The North Korea Problem
  2. Is radius perpendicular to the circle?

    An axle is perpendicular to the plane of a circular wheel but it is not quite a radius.
  3. Pseudo objects

    There are not many 'pseudo' objects that can be collected or modelled electronically apart from things like Einstein rings and crosses.
  4. Pseudo objects

    It's also interesting what other objects, pseudo or otherwise, you can capture with a feedback loop with the camera at various different angles, with or without mirrors. If you right click on an image and select view image in new tab, you will see the number of mirrors in the image name.
  5. Pseudo objects

    I noticed that I can post images so here are a series of images as referred to above. I made them around 20 years ago and I suspect they are hardware dependent i.e. the Pentium 233 MMX was the first CPU with built in graphics processing and the CRT is necessary for the behaviour of the display. So you probably won't be able to duplicate them with a modern PC/LED display and camera. Technically the screen capture images are Poincare sections of photons/light travelling around in a circle. The photons travel through air between the screen to the camera's CCD, via encrypted electronic charges from the CCD to the CRT and finally as electrons in a vacuum through the CRT to the phosphors on the screen. If you look into things in more detail you will see that the final stable halo state is actually an "Einstein Ring" so the ones we see in our astronomical observations must be in sync with the rotation of the object going around/in front of a star and our observational granularity/depth of field. At no stage do you actually see the photons travelling between the screen and the CCD with your eyes but they must exist or the images would not be produced so they are 'pseudo objects' to our eyes. Unfortunately I never managed to get an image of the final stable halo state, it is so fascinating and mesmerising that I clean forgot to take a screen shot. I only managed to get to this state twice because you must place your finger on the screen in the dead centre of the orb shape and get it out within 1.7 seconds or you won't get it right. When you do get it right the orb swells outwards and goes into the stable halo state with the counter rotating waves running around the inside and outside. The other images shown show various other configurations of just the bare loop or with one or 2 mirrors introduced into the loop, in number 4 I placed my finger on the screen next to the orb shape.
  6. Pseudo objects

    My avatar (top left of this post) is a screen capture of a feedback loop that comprised a digital camera pointed at a computer screen. (if you right click on the avatar and select open image in new tab you will see the edges of the window) The camera was on a pedestal approximately 3 feet from the screen and was set so that the light from the square viewing window was being fed back and was twisted into the spherical shape you see due to lag at the extremities i.e. the previous screen captures, at 25 frames per second via the camera's CCD, are twisted due to the camera being at 3 different angles to true 90 degrees in front of the screen and form the consistent spherical shape. I placed my finger onto the screen and removed it within 1.7 seconds to introduce a shadow into the feedback loop. The shadow in the centre of the spherical shape is a 'pseudo object' that consists of a truncated conical shadow that exists in the feedback loop between the screen and the cameras CCD at all times. The image shown is half way to the final state that appears like a stable halo with a ring of waves travelling in opposite directions around the outside and inside of the halo. The initial spherical shape in the feedback loop is stable and the halo formed by inserting a shadow into the feedback loop also remains stable while undisturbed. Once the halo shape is disturbed it reverts back to the stable spherical shape. If anybody would like a series of images of the feedback loop setup and various images pm me with your email address. All the images are screen captures and they are exactly what you see with your eyes when you view the feedback loop in a dark room.

  8. What are you reading?

    I just finished 'Anabasis' 3 & 4 by Xenophon. It tells the story of the march of 10,000 ancient Greek mercenaries northwards from near Mosul through the warlike Kurdish tribes and others in what is now Armenia and Turkey to finally arrive at the Black Sea. They were deceived into fighting for Cyrus in an unsuccessful attempt to defeat his brother, Artaxerxes, the Persian emperor and had many of their generals killed in another act of deception before the young Xenophon spoke to them of their options and was appointed as a general. Xenophon later went on to write the 'Hellenica' which took on the story of the Peloponnesian war between Athens and Sparta after Thucydidies left off his story.
  9. Earth's magnetic field is not about to reverse

    If you looked at the link I posted, on GPS Block IIF satellites, you'll see that the latest satellites, GPS Block IIIA, are due to start being launched around now. The first GPS Block I satellite was launched in 1978 and was called NAVSTAR GPS and was used for concept verification while the first GPS Block II satellite was launched in October 1989 and the last in October 1990. During the first gulf war (1990/91) GPS had this thing called Selective Availability which was retired in 2000.
  10. Earth's magnetic field is not about to reverse

    You said it Janus and others who note UTC time (based on GPS) discrepancies know how unreliable it has been recently, I noticed that one of our Bureau of Meteorology radars, a relatively new high tech dual polarisation radar, had its UTC timer out by 4 hours from April 2 to April 6 between at least 6:00 am and 11:00 am AEST this year. I stayed up the next morning on April 7 and noticed that the radars UTC time was correct at 3:00 am AEST, was out by 30 mins by 3:30 am AEST and was correct again at 3:35 am AEST. I also noticed further weird UTC discrepancies in the mornings from March 25 while following the Tiangong 1 reentry on and they receive data from radars all around the world. The current GPS Block IIF Satellites have reprogrammable processors that can receive software update uploads so that's about the only way GPS could possibly be out by exactly 4 hours for a fixed time period over many consecutive days for many different radars around the world. That's probably why Europe, Russia, China and even Elon Musk either have or are currently setting up their own GPS type systems.
  11. Review requested

    Hi Shauno, You are using the standard Compton wavelength λ instead of the reduced Compton wavelength ƛ (barred lambda).
  12. Hi Janus, If you only examined face on galaxies, where the light from all parts depart at roughly the same time, would the shift component of the light reflect the direction the galaxy was travelling in at the time of emission plus any cosmological recession shift of the emitted photons during transit? Surely a selection of face on galaxies of all types could be expected to be just as representative a sample as a mix of all types of galaxies with different planes of rotation and extra shift components. Has anybody studied face on galaxies alone to analyse their various shift components and the respective limits of their directional/recessional velocities?
  13. So if you regard the 'reduced' Compton wavelength ƛ (barred lambda) as 1 radian your 'standard' Compton wavelength λ effectively becomes 2π times λ, to keep the difference consistent, so when you multiply the ordinary matter component of ΛCDM by 2π you get the total matter component!
  14. If you regard the reduced Compton wavelength as 1 radian instead of 2π radians you can conflate the reduced Compton wavelength with the standard Compton wavelength.
  15. Strange, Arthur Compton demonstrated the particle nature of electromagnetic radiation in 1923 through his discovery of the Compton Effect. Considering that the reduced Compton wavelength is a natural representation for mass on the quantum scale, and Arthur Compton did his work in the early days of QM, it is unusual that modern QM appears to disavow particle/wave duality, or at the least seems confused about it. ttps://
