Welcome
I'm Armin, currently a PhD candidate at the University of Tehran. I am interested in Gravitational physics and currently, I am studying regular black holes (Singularities are bad, aren't they...!)
I'm also interested in classical and rock music (along with some sub-genres), and I enjoy exploring philosophy and psychology through my reading. If you wish to contact me, do not hesitate to email me.mail@arminsadeghi.net
