Dale replied to the thread Undergrad Why ##a^0=1##?.What are the laws of exponents that you refer to here? Please be explicit. -
Dale replied to the thread High School A simple Black Hole question I can't find an answer for.Umm, that is what destroys things. The tidal forces grow without bound. Any object composed of multiple fundamental particles will have... -
Dale replied to the thread Graduate A rotating frame equation for the "carousel experiment".There is no such thing as Coriolis-only. In the rotating frame there is a centrifugal force everywhere except at the axis. The real... -
Dale replied to the thread Graduate A rotating frame equation for the "carousel experiment".I think this is the issue I take. Just because you have a way that you prefer does not make the mainstream approach wrong. You are... -
Dale replied to the thread Graduate A rotating frame equation for the "carousel experiment".I read the Persson and the Edward’s articles. I liked the Edward’s one. But all they are doing is making an effective gravity which... -
Dale replied to the thread Graduate A rotating frame equation for the "carousel experiment".You can always transform to a different frame if you don’t like the centrifugal and Coriolis terms. But if you are using a rotating... -
Dale replied to the thread Graduate A rotating frame equation for the "carousel experiment".Yes, except then. -
Dale replied to the thread Graduate A rotating frame equation for the "carousel experiment".It will never be Coriolis only. There is always the centrifugal force too. What’s the problem? -
Dale replied to the thread Graduate A rotating frame equation for the "carousel experiment".The one you linked to above? It doesn't even support your claim. Give the actual reference. If something is a matter of choice then it... -
Dale replied to the thread Graduate A rotating frame equation for the "carousel experiment".So you start with an inertially moving object and you simply write its equation of motion in the rotating frame? Is it supposed to be... -

Dale replied to the thread Graduate A rotating frame equation for the "carousel experiment".What is the carousel experiment? -
Dale replied to the thread High School Why does continuity still feel weird?.The nice thing about that is that having a rigorous approach to infinitesimals allows you to correct some of the errors that people make... -

Infintesimals are part of the hyperreals and so basic arithmetic is allowed ie canceling like infintesimals. Hyperreal number field was... -

This may not be germane to the subject of this thread, but epsilon-delta proofs have been the bane of many calculus students, myself...
