Hi! I am physics passionate and I have always tackled a bit of this and a bit of that in other sciences. I have recently found out that there is something called forensic science (like in CSI stuff). No, seriously, I found out that this is a thing like two weeks ago, so I want to see what's with it. But I was unable to find advanced free books on the topic (unlike for physics and other sciences). I don't cheap books like popular science books. So, can someone help me?
