I feel this blog as a reflection of my thoughts to myself , and sometimes as a public diary, and the last she is my best friend to share my thoughts who says never a "oh no! ,you shouldn't....That Disgusts...."

Why dirac delta function/distribution has become more important

If you see functions as vectors in uncountably infinite dimensional spaces then the analogy of standard basis{e_i} in finite dimensions would lead to the set of dirac-delta distributions {delta(x-i)}.

E.g:  X.e_i =X_i
        f(x)*delta(x-i)=f(i)
