Hi, I am wondering about the process of protecting one's intellectual work before and during publication. I am in the process of preparing a series of papers that contain a combination of old and new ideas to the field of study they are in. I'm a professional musician also, familiar with the world of copyrights, but I'm aware that I cannot copyright an idea or theory. I simply want to be able to show evidence of the time period during which I developed this work so that if it becomes used in the future I will be credited. this is set of papers in theoretical physics. what do people usually do? thank you for your help!
