Hi! I was actively participating in Physics.SE until 2014. These days, I'm involved in some open-source stuff.
I'm grateful to this community for teaching me English, Physics and more importantly, how to collaborate. That explains why some of my really old posts are really hard to read or have flawed understanding of some concept. Maybe one day I'll revise everything and probably participate again, but until then, my apologies to you for having to put up with my writing.
