I would say "Hello everyone!" here but that would be sort of redundant, wouldn't it? I am currently studying Physics in Universitat de Barcelona (just about to begin third year of that Bologna bachelor) set to Astronomy/Astrophysics. I almost literally stumbled upon this forum while searching the solutions for some Optics problems, and I saw a good place to seek, and eventually give, help, as well as broadly expanding my knowledge. So, as I say this I'm already set to begin enjoying this new experience. See you around!
