Hi
@Oscar
I agree,wiki is as reliable as a layman can get,however for technical subjects ranging from things like poissons's summation rule,various concepts in signal processing,duality etc are pretty standard(with decent references)- however the same cant be extended to wiki articles on non-technical subjects like war,combat losses,and similar subjects.For these subjects,we need to go through very credible research literature put forward by people who have spent considerable time going through the matter- for instance if you want to analyze the war history of india and pakistan or for that matter between any two countries then you would have to go through articles written by credible people WITHOUT any BIAS with proper credible evidences!- serial number,catalogues etc(here i would like to point out that while PA might have done separate studies to access the losses at regiment and brigade level in various wars(most notably the kargil),but i am afraid they would ever make that "data" available to public- something that is considered a NORM in india).Hence any data quoted by pakistani academicians on these matters is at best their guess with certain bias offset
@Oscar
In fact it would come to you as a surprise that i derived the essence of poisson's summation rule(the very fundamental of DTFT) all by my own,using a different logic,but then i ran into wiki article on poisson's summation rule which was pretty elegant,i was a bit taken back that such a thing already exists lol- but anyways,my point is,you can get really decent wiki articles on technical subjects!
