Hello, PF, my name is Jacob. I posted once before but never really dove into the physics community as I wanted to. I've had a passion for astronomy since I was a young boy but recently found an interest in physics despite having a hard time with mathematics growing up. I joined the Marines after high school did security work after discharge, so now that I'm 23 and only have an understanding of algebra 2, I'm playing a serious game of catch up if I want to eventually get a higher degree in astrophysics and study other natural sciences. In joining PF, I hope to get a better understanding in the sciences and hopefully better get affiliated with a community instead of trying and failing at self study as I have been. Any advice on how to start improving my knowledge would be helpful beyond words. Thank you!
