Conduction, Induction and Induction and Grounding in an Electroscope: LD Industries Physics 30
Are you stuck on figuring out what happens with the interactions between a charged rod and an electroscope? Here's a video for that. I also go through three methods of creating separation of charge: conduction, induction and induction and grounding. This video fits with Unit B in the Alberta Physics 30 program of studies.

    Hello. Let's measure the Universe with gravitational quanta (more precisely in digital format)?! With the help of the “HYBRID gyroscope” you can make scientific discoveries; in astronomy, astrophysics, cosmology, higher theoretical physics,... I am writing to you with a proposal for the joint invention of a HYBRID gyroscope from non-circular, TWO coils with a new type of optical fiber with a “hollow core photonic-substituted vacuum zone or (NANF)” where - the light travels 250000 meters in each arm, while it does not exceed the parameters 88/88/88 cm, and the weight is 14 kg. Manufacturers of “Fiber Optic Gyroscopes” can produce HYBRID gyroscopes for educational and practical use in schools and higher education institutions. Einstein dreamed of measuring the speed of a train, an airplane - through the Michelson-Morley experiment of 1881/2024, and only then would the experiment be more than 70% complete. This can be done using a fiber optic HYBRID gyroscope. Based on the completion of more than 70% of Michelson's experiment, the following postulates can be proven: Light is an ordered vibration of gravitational quanta, and dominant gravitational fields adjust the speed of light in a vacuum. (We are not looking for ether, we will see the work of gravitational quanta) The result is a «theory of everything» in a simple teaching device and a new tape measure for measuring the universe.

    The one way farfield speed of light has been measured and it is c. This was done by transmitting a radio wave from one dipole antenna to another dipole antenna, where both the transmitted signal and the received signal are measure by one oscilloscope (ie. one clock). The orientation of the 2 antennas were pointed in many directions and experiment was repeated many times over months. But the experiment showed something unexpected. It showed that speed of light is instantaneous in the nearfield and reduces to the speed of light about 1 wavelength from the source. Since Relativity assumes light only propagates at speed c, and this has been shown to not be true especially in the nearfield of the source, then Relativity needs to be reanalyzed. Derivation of Relativity using instantaneous nearfield light shows that Relativity reduces to Galilean Relativity, and only in the farfield does it reduce to the speed of light c. This is because as c=infinity, the Relativistic gamma function becomes equal to one, causing the Lorentz transforms to reduce to the Galilean transforms. But using farfield fields yields the Lorentz transforms. But since time and space are real and can not depend on whether nearfield or farfield fields are used (i.e what frequency of light is used), then the effects of Relativity on time and space must be an optical illusion. Time and space are absolute as indicated by Galilean Relativity. When moving objects are observed using farfield electromagnetic fields then time can appear to dilate and space can appear contract, but the effects are not real and can be verfied by using nearfield electromagenic fields which will show time and space have not changed. Since General Relativity is based on Special Relativity, then the effects of General Relativity on time and space must also be an optical illusion. So what is a better theory of gravity if General Relativity is wrong. It is well known that General Relativity reduces to Gravitoelectromaganetism for weak gravitational fields, which is all that we observe. Consequently Gravitoelectromagnetism predicts all known observed gravitational effects. But the difference is that Gravitoelectromagnetism is a field theory, whereas General Relativity is a geometric theory. Gravitoelectromagnetism assumes gravity is modeled by 4 equivalent Maxwell Equations as for Electromagnetism. The equations only differ in the constants used. Gravitoelectromagnetism is field theory of gravity and assumes there are both an Electric and Magnetic components of gravity. Just like for electromagnetic fields, changing magnetic fields create electric fields and visa versa. Gravitoelectromagnetism also assumes time and space are absolute and not flexible as General Relativity predicts.

    secondly, in this michelson experiment, what kind of a light did he use? was it a pulsating laser or something? cause if not, then a fast rotating mirror will simply create a circular reflection along the mineshaft and at all times light will be hitting the observer. am i right or am i wrong? i hope this is not met by silence. cause, that would only further tell me that finite speed of light is a lie. another reason to belive this is the case is because, there is no recorded experiment that shows this. and its difficult to do as is, and apprantly fizeau had a light in 1849 that could reach upto 8 kilometers away, and then bounce back to him, for him to record. how is that even possible? in 1849? what kind of a light did he have? how was he able to focus it like a laser in 1849? how did he have a mirror that could give him a sharp image from 16kms? and why dosent anyone perform this in 2022 with all the modern tech?

      I have not read what the light source type was that Michelson used, but I did read that he used telescopes to be able to detect the light source. Lasers were not invented until 1958, so that light source is out. I imagine there was some interference from reflection, and that he perhaps saw brighter light when the spinning mirror was in the correct position. This article has some good background on his experiments and the designs: artscimedia.case.edu/wp-content/uploads/sites/175/2016/03/14222233/chap-3-ni.pdf I’m sure there are other modern attempts at refining the speed of light measurements, but I’m not aware what there are.

But the "accepted" speed of light is for a vacuum; what is the accepted speed of light at atmospheric pressure? Does that factor make his measurement closer, or does it shift too far and make Michelson's measurement too high?

      That’s a good point. The index of refraction of air is 1.0003, compared to exactly 1 for a vacuum. So light moves 1.0003 times slower through air, which is 299,882,396 m/s, or about 90 km/s slower. Although I don’t know exactly what atmospheric conditions Michelson conducted his experiment at. It’s an ingenious way of measuring either way.

    To keep the mirror from exploding, Michelson used a 16 sided mirror. The light traveled 8448 one way trips per second, or 4224 two way trips per second. The mirror rotates 1/16 of 1 revolution for each two way movement of light. The emitted light and the received light are on the same 90 degree axis to the two way path of light. This is important as it limits the errors.
