Thank you to members of Georgia Tech Society of Physics Students for taking the time to write up additional solutions for Townsend. Similar to my earlier approach of writing solutions as I read the text, a group of motivated students at Georgia Tech pursued this project in parallel with their Quantum 2 class this past fall. It’s a pleasure for me to facilitate sharing these resources to help more students learn quantum mechanics. Congrats to Charles Cardot, Cody McCord, Robin Glefke, Kiernan Reising, Kevin Jin, Alexander George-Kennedy, William Benston, and all others for this great contribution!
