How did you find PF?
Bing search: In fact, I was searching for the answer to the question "Can a rest frame be chosen for the center of momentum for a system of two photos? " in Bing, and the PF pops out.

Welcome to PF! :smile:
 
Hello fellow Physics enthusiasts, I am an aeronautical engineering graduate (Bachelor's) who is interested in Physics and Mathematics, and I have been re-learning all the basics. I wanted to join a science forum, especially one dedicated to Physics and maths, to apply these subjects to my engineering studies. I hope to learn a lot through this forum. Thank you for your warm welcome.
