@BernardoMeurer I do know someone who's moving there, so it's not absolutely impossible as I'll (probably) be in the USA for a couple of months at some point in the next couple of years. But I'll be in Indiana, so it's not exactly close by any means :/
Idek what you're interested in. There's an ancient prophecy around my family bloodline, "He who finds us shall be blessed by infinite books on Physics and Computer Shit"
@BalarkaSen I went to a maths lecturer in my Uni who I like and speak to a fair bit, and showed them a couple of my shoddy-notation-bound 'proofs' of rank nullity, one via an argument using bases and one using equivalence relations. Apparently, notation aside they were fine, but they recommended I consider "extending the basis" instead, as a more direct and less complicated method, but I don't really get what they mean : / I get that a basis can be chosen for the Kernel, where any..
n amount of linearly independent vectors can be chosen to span the Kernel, but what's the deal with "extending the basis"? Why is it useful to consider?
@Abcd Surface tension acting on the fluid surface is the reason behind area-minimization. If you put a small rubber band on the surface of water in any initial shape, it'll deform itself to have the shape of a circle (google "isoperimetric inequality")
Hmm, I guess I'm used to stack overflow where it seems almost every question that I browse is answered. Or maybe I just haven't been browsing long enough to really tell...
