Quote from: Bored chemist on 20/10/2022 20:02:25But you can have a policy about people who persistently ignore the laws of physics or persistently break the rules.Like Bruno, Galileo, Newton, Einstein, Maxwell.....not to mention Semmelweiss, Pasteur, Jenner, and everyone else who flagrantly ignored the laws of chemistry and the practice of medicine.Science is different from mining. It can take decades to recognise a nugget, and only then do you realise that everything you once considered valuable is actually dross.Problem is that an awful lot of new dross is presented here as potential nuggets. But it keeps the miners alert and amused.

The voltage shown in the Voltmeter of the experiment must be generated from these mass flow difference of the ions, considering that other factors are equally applied to both containers. But some factors may effectively reduce the voltage, such as adhesion, cohesion, molecular dipole, etc.
Avshalom Elitzur, Michio Kaku, Tim Maudlin and Jimena Canales thrash out the implications of what current physics says about the nature of time.Does time really flow in the way we think it does?In our everyday experience, time is an inescapable backdrop against which events unfold, allowing us to sequence events and measure durations. Yet in the hundred years since Einstein's theory of general relativity, physics has had a radically different account. Time does not flow, there is no before and after. We are not born and we do not die. The entirety of spacetime is given at the outset of the universe. There is no cause and effect. Is this radical discrepancy with our everyday experience a threat to physics or a threat to our understanding of what it is to be alive?Should we take seriously claims of physicists that everyday experience is an illusion? Or is it their model of the universe that is mistaken? Or are these two profoundly different accounts of time the product of frames of understanding that will always remain incompatible?#michiokaku #time #physics Quantum theorist Avshalom Elitzur, theoretical physicist Michio Kaku, philosopher of physics Tim Maudlin, and historian of science Jimena Canales delve into the fascinating conundrum of time.

If you watch carefully, you may find what looks like a mistake in the Veritasium video about electricity, magnetism, and special relativity. Here I explain that apparent mistake.
Magnetism seems like a pretty magical phenomenon. Rocks that attract or repel each other at a distance - that's really cool - and electric current in a wire interacts in the same way. What's even more amazing is how it works. We normally think of special relativity as having little bearing on our lives because everything happens at such low speeds that relativistic effects are negligible. But when you consider the large number of charges in a wire and the strength of the electric interaction, you can see that electromagnets function thanks to the special relativistic effect of length contraction. In a frame of reference moving with the charges, there is an electric field that creates a force on the charges. But in the lab frame, there is no electric field so it must be a magnetic field creating the force. Hence we see that a magnetic field is what an electric field becomes when an electrically charged object starts moving.
Now I'm done recording the experiment using 3 types of chloride salts, ie NaCl, KCl, and MgCl2. It will take some time to edit, add narrative and illustration, and then upload it to my YouTube channel. So please be patient, since I'm having a tight schedule in my work place. So little time so much to do.

So little time so much to do. Her are some observations during the experiment. Even with the same solutions in both containers, and no electric current flowing through them, some voltage was shown. It disappeared when the cans were connected, but reappeared after they were disconnected. Difference in volume of the liquids affects the voltage readings, even with no current. Electrostatic charge build up on the liquids affects the voltage readings. It can occur when the liquid is poured into the container, or other handling related to triboelectricity. To minimize variance, the solutions used in the experiment were set to have conductivity around 19 mS/cm, because the portable conductivity meter I used can't show any value above 20 mS/cm.
What is Gravity? This video will show the reasons why Gravity can be understood as a side-effect of normal electromagnetic forces. In this ongoing video series, I will show several science experiments to demonstrate the special forces from the divergent electric field. I will also show how the Laplace Force from the Lorentz Equation is an important key to understanding gravity as an electromagnetic effect and is the "engine" behind the electric universe effects.
A physicist youtuber thinks that electricity and magnetism are the same thing.
Hence, it would seem that there are some B fields that cannot be reduced to an E field in any frame.
Doesn't it mean that they are not the same?
On the microsocopic level, such as in the standard model of particle physics, the E and B fields are considered to be manifestations of the same sort of interactions by the same gauge boson.
Under the standard model of particle physics, there isn't a B and E field. There is a photon field and separate fields for all the other particles. On this scale or using this model, it would still be correct to say that the interactions are due to one common field.
String theory lied to us and now science communication is hard.This is just my opinion man. String theory is not bad. String theory is fine and interesting. String theory was communicated.....you could say poorly or could say deceptively.
What caused the voltage in my electrodynamic balance, according to the standard model?
