Mathematics news on Phys.org
Yet another site with good information packaged in an ugly fashion
 
dave rusin is a mathwiz! his posts at rec.puzzles could leave anyone open mouthed ... ! Also check rec.puzzles for many problems in math that u may like to cherish!

I remember this site. I came across it when I was in one of my frequent math moods while online. And, you're right, Tom, it is quite an ugly site. I was only there for a few seconds.
 
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...
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...
