I am a freshman in physics at this point, and looking to get some ideas of some things that I might want to add to my Christmas wish list involving my profession? Although this probably won't make much of a difference, I am a 34 year old adult changing professions to one I have always loved, and I would really like some new toys to play with that I will enjoy and at the same time will teach me more about physics. My primary passions are in quantum physics and astrophysics, though I plan to get my doctorate in something involved in quantum. I was considering a microscope, though I felt this isn't going to help me learn a whole lot about physics, but rather chemistry. Also, a telescope is off the table. Nobody that is giving me gifts has enough money to get one that would be very powerful, and I know I would get tired of it fast. Besides, I find plenty of images from space online. So, does anyone have any other ideas? The price range should be around $10-$40 or so. I appreciate any feedback anyone can provide.
