    Symmetries in quantum mechanics describe features of spacetime and particles which are unchanged under some transformation, in the context of quantum mechanics, relativistic quantum mechanics and quantum field theory, and with applications in the mathematical formulation of the standard model and condensed matter physics. In general, symmetry in physics, invariance, and conservation laws, are fundamentally important constraints for formulating physical theories and models. In practice, they are powerful methods for solving problems and predicting what can happen. While conservation laws do not always give the answer to the problem directly, they form the correct constraints and the first steps to solving a multitude of problems.

    This article outlines the connection between the classical form of continuous symmetries as well as their quantum operators, and relates them to the Lie groups, and relativistic transformations in the Lorentz group and Poincaré group.

    First para is kind of definition.
    Second para should link to some article, but it does not appear.

    I don't think it's plagiarism, for definitions one need not cite.

    This is not a mere definition, it's the full lead taken straight from the Wikipedia-article, without attribution. Wikipedia articles fall under the CC Attribution-ShareALike license (as stated at the bottom of the article), and the quoted section is more than a full paragraph. I wouldn't be surprised if heyuhua just committed a copyright violation. But I'm not a legal expert.

    i have read some comments regarding "spacetime" as being a discription rather than an actual physical measurable thing.
    while i stumble on the application of the word, i also wonder how mathamatics deals with Schrödinger's cat
    https://en.wikipedia.org/wiki/Schrödinger's_cat

    thus laws of conservation.

    I don't interest this, you may get NotEinstein to comment on your point of view, he knows everything.

    a little more detail of my question which i probably should have phrased a little better.

    "how does the 'Laws of Conservation' get represented in a mathamatical explanation of Schrödinger's cat " ?

    This is clearly plagiarism, it is a copy and paste from wiki, not a single word in the post is from heyuhua. It may very well have been unintended but it is plagiarism none the less.

    The point is that you are breaking the site rules (again). If you copy and paste something from another site that you did not write you are required to acknowledge the source of the copy and paste.

    no no no, there is nothing new in this passage. The text is copied from the textbook by wiki. You might as well attack me before you attack Wiki.

    Yes, I know that.
    That is the problem.
    I am not attacking anyone.

    We are having a translation problem. Look at the translation of plagiarism.

    One of the forum rules is that you must cite the source of any material you copy.

    I am simply trying to inform you that you are breaking a forum rule for plagiarism.
