Ah, yeah, it's not a fixed system in the sense that it has parameters assumed constant, and I'm looking to make a template. As for additional details, well, the initial system can be reduced to a system involving only 2nd degree polynomials, so I assume every polynomial in the initial system is...

Hello, I'm here because I lack experience and education in the subject of systems of polynomial equations (univariate and multivariate). I've also recently found a need to work with them. If this is the wrong subforum, then I apologize for my ignorance and would be grateful if a moderator...

Note: If this is the wrong sub-forum for this question please move it. I was not sure if this question should go in the General section or not. Question: I want to create a smooth non-piecewise curve in ℝ^{3} (3-space) such that it's intersection with the xy-plane consists of the integer...

Thanks for the replies. They were all much quicker than I thought, and all very helpful. I guess I have one follow up question to what Peter was saying "Note that the energy has to be measured in the CoM frame of the system as a whole". I thought that the useful part of rest mass was that it...

I have a few questions concerning mass that I'm hoping some kind soul more knowledgeable than myself can answer for me. Most of these concern mass energy equivalence, although two, I think, are classical questions that I have not even had to consider for several years (although they just passed...

Implicit isomorphism involved in extension/sub fields/structures? This has been bugging me for a while. I'm pretty sure I'm correct but I'd just like to verify to put my mind at ease. I'd like to know if there is an implicit isomorphism involved when we say, for example, F is a substructure of...
