Yes, my first choice was Australia and I was planning on it since my aunt is living there and it would make living in a foreign country much easier, then U.S, but a series of events led to decision to study MS here in Iran. If I ever decide to study Ph.D, I will go to a good foreign university.
About engineering, I think in Iran, it's even more popular than Arab countries, there is some kind of obsession with engineering (and university degrees overall in here) and that's not necessarily a good thing. As a result, we are lagging behind in some other fields, like humanity sciences or economic studies etc, but hopefully, the obsession with engineering is diminishing by time.
I myself am no exception, I am studying MS in Material science and engineering, but I love it to be honest, wasn't all about obsession. My main field of interest is composites and nanocomposites (mostly polymer-based ones) and my MS project/thesis is also going to be about a polymer based nanocomposite.
First one is Mohammad Ali Jafari, commander in chief of IRGC, second one I have no idea. Also, Jafari is not a Sayid.
PS: I thought you were asking about first pic, my mistake.
I don't know those 2 Sayids in second pic either, but third one is Jafari which I explained above.
