Hi PF, I'm moving to the UK from the US to start on a M.Sc. in plasma physics this fall. I really want to take some of my undergrad textbooks with me, but the shipping charge is outrageous. There are about 4 books that I must have, but I'd prefer more than that. A 10lb Fedex box said it would cost almost $200 to ship these 4 books in a box together. So I thought I'd maybe put them in a cardboard box and take them onto the plane as my "personal item" that's allowed alongside your carry-on. Do you think I will get any trouble from security for transporting any of these books? The books are the following Classical Mechanics by Taylor E&M by griffiths Intro to Plasma Physics and Controlled Fusion by Francis Chen and a PDE book, I forgot the author. If possible I'd like to take a couple other books on heat transfer and fluids if I have room.
