Ladies and gentlemen, I thank you all. I still think you do not understand my difficulty. I hope you will see this is not filibuster... -
weirdoguy reacted to sophiecentaur's post in the thread I Is calling fictitious forces "not real" just about terminology? with
Like.
Ditto. Did you actually mean post #36? I'm talking about regular people using regular methods of solving and discussing mechanical... -
weirdoguy reacted to douglasluis's post in the thread Hello from Brazil – independent researcher working on field-simulation with
Skeptical.
I’m an independent researcher from Brazil, interested in physics and mathematical modeling. As a neurodivergent person, I often see... -
weirdoguy reacted to DmitryS's post in the thread I The Einstein Clock aka Light Clock with Skeptical.
That's what I call a discussion. Right, I want to summarize now what I see, because I can't really reply to all the minor things that...

weirdoguy reacted to coquelicot's post in the thread A Jackson: justification of the Poynting vector by GR with Skeptical.
This seems interesting. I sent you a direct message to your inbox, as this kind of discussion usually leads to non main-stream...
-
Strictly speaking the first Newton law says that inertial frames do exist. By definition an inertial frame is the frame in which...

The AI will "believe" whatever most of its training data says. Majority rules. This is why I have no faith in AI and pay no attention...
-
You keep pointing to contrary "observations". To support that claim, please cite a scholarly reference that exhibits what is observed...

weirdoguy reacted to bhobba's post in the thread I Question about discussions around quantum interpretations with Like.
And many, like me, think that is because we have no DIRECT experience with the quantum world. It is tough to apply how we think about...

weirdoguy replied to the thread A Is the variation of the metric ##\delta g_{\mu\nu}## a tensor?.Yes, but still some people wouldn't call those tensors "the same object". Especially most mathematical physicists/mathematicians that I...

weirdoguy replied to the thread A Is the variation of the metric ##\delta g_{\mu\nu}## a tensor?.Are they? Tensors are mappings from cartesian products of vector spaces and their duals. What you wrote are coordinate representations...

weirdoguy reacted to A.T.'s post in the thread I Synchronizing clocks in an inertial frame if light is anisotropic with Like.
It sounds backwards, but makes perfect sense. Similarly to this:

weirdoguy reacted to PeroK's post in the thread I Is calling fictitious forces "not real" just about terminology? with Like.
Nothing. They are just different names for the same things. If you taught a class of students using those terms and a class of...

weirdoguy reacted to A.T.'s post in the thread I Is calling fictitious forces "not real" just about terminology? with Skeptical.
Physists of the past have been brilliant at describing nature using math, but terrible at choosing the right words for it. Both naming...

weirdoguy reacted to PeroK's post in the thread I Is calling fictitious forces "not real" just about terminology? with Like.
I must admit I don't generally use the terms "action" and "reaction". But, "real" and "fictitious" make perfect sense to me. I never...
