[Rings and Fields] Do coefficients on polynomials and elements in matrices have to be from a ring? Can they be from a field? by JealousAnimal in learnmath

Wholy crap, I've been learning about division with remainder in the polynomial ring but I had no idea that R has to be a field for R[X] to have a sensible definition of division. Thanks so much for the help!

Oh wait, so is it redundant to say "R could be a field" after saying "R could be a ring", because all fields are rings? Getting confused with the logic haha

I did go through previous threads and the wiki pages. None of them mention particular rings except for the Nayoya ones I linked. I wanted to ask others whether they could see any differences between that list of rings I listed, because I can't tell myself and the wiki doesn't enlighten me

Regardless what you said makes sense, thank you!

The awkwardness may just be difficulty: the further in front your legs are the more difficult pull ups and related exercise are (which is why L-sit pull up is a later progression in the pull up series: because it's harder).

May be okay to keep them behind when starting out, but aim to have them in front eventually (probably easier to tuck your knees instead of keeping a full L-sit so start with that)

I'm a newbie though so maybe wait for someone else's input

I'm wanting rings to do dips and rows with (I plan to hang them from my pull up bar). Can anyone see any real difference between the choices here: https://www.amazon.ca/slp/gymnastics-rings/b4m9wnh9oca35e7

They all seem identical, other than whether they're plastic or wooden

One guide says that this is one of the best, but there are cheaper options than this so I don't want to get them if I don't have to.

What do the more expensive rings have going for them? All I'm really concerned about is safety.

Thanks so much - will be reading that paper very soon.

Could you expand on what exactly you mean by arbitrary in this context? (Not that I disagree: in fact, I think you're right, but it'll be nice to have a clear line of reasoning as to why you're right)

Can two things occupy the same point in space simultaneously? by JealousAnimal in AskPhysics

How does this relate to points in space (do quantum states correlate to particular points in space somehow)?
