It is! It is superior in many ways, in particular as it takes the physics of measurement seriously, that you can't like in classical... -
weirdoguy reacted to Trysse's post in the thread Does the Lorentz factor aid understanding of SR, or obscure it? with
Skeptical.
Sorry that it took me so long to come back to this thread. I was waiting to see if there was somebody who shares my issues with the... -
weirdoguy reacted to Simon F's post in the thread Graduate A rotating frame equation for the "carousel experiment" with Skeptical.
There is no choice if you want to display a Coriolis-only effect. The classical carousel experiment is wrong. Students who do not...

weirdoguy reacted to Simon F's post in the thread Graduate A rotating frame equation for the "carousel experiment" with Skeptical.
The location of the carousel/turntable is not important because the rotating system is the carrousel/turntable not the Earth. This is...

weirdoguy reacted to Simon F's post in the thread Graduate A rotating frame equation for the "carousel experiment" with Skeptical.
My topic was about presenting an alternative equation without Coriolis and centrifugal terms. I dot not want to spend too much time...

Like.
However, any other contributing mechanism has very tight restrictions on what it can be, for the same reasons other models were ruled... -
weirdoguy replied to the thread Undergrad Why ##a^0=1##?.They do, as ##a^x## clearly shows. But you blindly run around the most simple problem with the most simple solution.
-
This approach doesn't explain why ##a^0=1##.

Or, more accurately, The limiting value for y as x approaches zero is one.

As was repeatedly shown by Anders Persson, https://rmets.onlinelibrary.wiley.com/doi/10.1002/qj.2477 <link removed> the "carousel...

Hardly an arbitrary choice; for the function to be continuous, the value at zero has to be 1.

weirdoguy reacted to .Scott's post in the thread High School For a lighter take on relativity.... with Like.
In college, I took a 19th century Literature course (strictly because a literature course was "required"). What became very evident to...

weirdoguy replied to the thread Graduate Error in Landau-Lifshitz Vol 2, Fig. 20, page 310.Yeah, I had all of them because of that (I was not interested in all the topics that some of those volumes covered). But I sold most of...

weirdoguy reacted to jedishrfu's post in the thread High School Why does continuity still feel weird? with Like.
Infintesimals are part of the hyperreals and so basic arithmetic is allowed ie canceling like infintesimals. Hyperreal number field was...

If you have to sit a standard analysis exam, then appealing to hyperreal numbers won't help.
