AI Thread Summary
In the context of proofs, "justify" means to provide a rigorous demonstration that supports a statement or theorem, rather than merely showing an example. Justification requires a comprehensive proof that holds true for all cases, rather than isolated instances. Terms like "substantiate" or "confirm" may imply support but do not equate to justification. Consequently, presenting an example alone is insufficient to justify a theorem. A clear understanding of this distinction is crucial in mathematical discourse.

when dealing with proofs, what does the word "Justify" mean? does it mean show an example or prove for all cases?
 
Mathematics news on Phys.org
it means prove it. An example might "substantiate", or "confirm" a statement, or "lend credence" to it, but would not "justify" it.
 
so showing an example would not be enough to "justify" a therom?
 
i only answer each question once.
 
yeah, mathwonk kind of just answered that questoin
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
