What is Term: Definition and 774 Discussions

A term limit is a legal restriction that limits the number of terms an officeholder may serve in a particular elected office. When term limits are found in presidential and semi-presidential systems they act as a method of curbing the potential for monopoly, where a leader effectively becomes "president for life". This is intended to protect a republic from becoming a de facto dictatorship. Sometimes, there is an absolute or lifetime limit on the number of terms an officeholder may serve; sometimes, the restrictions are merely on the number of consecutive terms they may serve.

    What is the purpose of the term 'Matter'?

    I will preface my question with the fact that I am a high school student with only a general knowledge of physics, though I have learned about a variety of phenomena at the limited level of depth that I am capable of. I am curious about several concepts and observed phenomena that are...

    Rearranging Equations where the term seems to cancel?

    So, on a recent maths paper I sat, there was a question where we had to make t the subject. (Disclaimer, this is not homework. I am simply curious, and cannot see how it works. Please don't Ban me) I could not do it for the life of me, because, seemingly the two ts cancel? I know this shouldn't...

    General term for splitting of light into constituents

    …… is the splitting of light into its constituent colors (wavelengths). Can I use the term ‘dispersion’ here? Or is ‘dispersion’ only restricted to splitting due to phase velocity/refraction differences of different wavelengths (prism)? If not ‘dispersion’, is there another general term that...

    No Time Term in Elliptic PDEs? Confirm Here!

    When looking at Elliptic PDEs that describe a physical system, do these typically not involve a time term? I have yet to see an elliptic PDE involving a time term, which seem to be associated with parabolic/hyperbolic PDEs rather than elliptic. Can anyone confirm?
