Other Struggling with illness and existential despair
You need to look for a psychiatrist, not a psychologist. A psychologist treats only with therapy. A psychiatrist treats with medication and adds therapy if it benefits the specific medication. It is fundamentally different from what you have described. Really? You are doing so well that you come...- Dale

Other Struggling with illness and existential despair
Maybe you need a psychiatrist instead of a psychologist. Many mental illnesses begin to manifest severe symptoms at around your age. Many of them need medication, not just therapy For me volunteering and service to others provide that sense of meaning. I do that through my church. If you are...- Dale

Replacing "inertial" with "elastoid-inertial" in rotating systems
This isn’t physics, it is just semantics. Any authors that want to use that terminology are already free to do so. As such we will leave this thread closed- Dale

Undergrad How does the geometry of magnetic bodies influence torque?
And @Ibix pointed you to the math to get the answers. If you need help working through the math, let us know. Show your work and let us know where you get stuck. You are, after all, an independent researcher. So independently working on some research is what you do. And luckily this part is...- Dale

Undergrad "The wavefunction never collapses"
I have wondered about this. Are they really mutually incompatible? They all share the same math and the same experimental predictions. So nature doesn’t seem to view them as incompatible. They are clearly all isomorphic to each other. So what more besides an isomorphism is required for things...- Dale

Undergrad How does the geometry of magnetic bodies influence torque?
@Ibix gave the dipole-dipole formulas. Try them out. However, if you find that the equations do not work, that does not imply that your experiment has violated textbook electromagnetism. It just means that your magnets are not simple dipoles.- Dale

Undergrad Is Water's Volume Expansion Upon Freezing an Intrinsic Property?
Excellent. Most of the suggestions you have received can be done with kitchen equipment. This is simply not correct. I have been a peer reviewer for well over 100 manuscripts. In all of those, I only knew who I was reviewing once (and that only because they cited themselves in the first person...- Dale

Undergrad Why is gravity a fictitious force?
This is tidal gravity. It is curved spacetime, not flat. It is physical gravitation and cannot be removed by a change of reference frame, nor described as a fictitious force.- Dale

Undergrad Why is gravity a fictitious force?
I am not sure what kind of scenario you are envisioning here. In flat spacetime there are no tidal effects. So what internal stresses are you talking about? Are you referring to something like a truss built with stressed members? Tidal effects are non-local. You cannot talk about tidal forces...- Dale

Undergrad Simplified Special Relativity: Looking to get roasted on this
I would say that too. A special case always fails to replicate a general case. By “replicate” I am talking about predictions. GR makes correct predictions that SR does not.- Dale

Undergrad Some notes on LET for reference
Yes. It just postulates the Lorentz transform directly. Then it makes all the usual predictions. No. LET is equivalent to standard SR and fails to replicate GR in the same way that standard SR does.- Dale

Undergrad Simplified Special Relativity: Looking to get roasted on this
Not really. The classic example of a non-falsifiable theory is “God willed it so”. It fits all the observations perfectly. The goal of a scientific theory is not merely to fit the observations, but to predict them. “God willed it so” fits all data but makes no predictions. It is precisely...- Dale

Simple kinematics problem — falling from a geostationary satellite
Yes. And at the point where they all meet the first two have the same velocity while the third does not. In the future please fill out the template completely.- Dale
