Dale replied to the thread Graduate Theoretical question on extra dimensions.We are asking you for the references. If not some AI hallucination, then where are you getting any of this? Specifically this part: -
Dale reacted to A.T.'s post in the thread Undergrad Why does Moment of Inertia have an R^2 dependence (logically)? with
Like.
You seem to have a general misconception about physics. Physics isn't math. Physics isn't linearly derived from axioms by "logic"... -
Dale reacted to Matterwave's post in the thread Undergrad Why does Moment of Inertia have an R^2 dependence (logically)? with Like.
One thing I'd like to emphasize here, just in case it gets lost in the math a little, is that the cylindrical coordinates are used here...

Dale replied to the thread Undergrad Why does Moment of Inertia have an R^2 dependence (logically)?.I would use a Lagrangian approach for this. For a free body in cylindrical coordinates the Lagrangian is: $$L = \frac{1}{2}m \left( \dot...
-
Dale replied to the thread Graduate The Planck scale, black hole interiors, observable universe and GR.No. Read what I wrote. I was complaining about how obnoxious it is to read AI writing. It has nothing to do with a criticism of your...

Dale replied to the thread High School Doing more work walking from the pole to the equator.My comment has nothing to do with dissipative forces. It has to do with you specifying a constant distance ##R## from the center of the...

Dale reacted to Filip Larsen's post in the thread High School Doing more work walking from the pole to the equator with Like.
I can see now that I both used the property that any mass at rest on the geoid in the rotating frame by definition have same potential...

Is rotational energy the only thing that has changed? Did you see the advice I gave to the OP: ?

Again though, remember: if you are at sea level the whole time, these forces do not come into play. Every molecule of water is subject...

Skeptical.
Regarding work required for the specified walk you would indeed need to provide work to gain rotational energy. If a person of mass... -
Dale replied to the thread High School Doing more work walking from the pole to the equator.Are you having the person walk underground at the equator or are they walking in the air at the pole? The geoid is not at the same...

Dale reacted to Baluncore's post in the thread Undergrad How Do You Measure Energy Conversion Efficiency? with Like.
That sounds like school or homework to me. You do not. You look at the total energy output in the form you require, and divide it by...

Dale replied to the thread Graduate The Planck scale, black hole interiors, observable universe and GR.Please don’t use AI. It makes your writing so unnecessarily long. It is obnoxious to read. That said, do you have a question?

Dale replied to the thread High School How can a local interaction affect different parts of an atom?.That is incredibly frustrating to hear since you literally said exactly that in posts 7, 9, and 13. And each time I asked for...

Dale replied to the thread High School How can a local interaction affect different parts of an atom?.That is completely unproductive. "Just think about it" is not an explanation. No amount of me thinking about it will explain your...
