CUWiP – This is the Conference for Undergraduate Women in Physics dedicated to diversity within physics (and focused on but not just for women). It is a great opportunity to meet people from other universities! There will be experts who talk about research, status of WiP, grad school, etc. You may also apply to present your own research.
APS – This is the American Physical Society. Be sure you become a member for your first attendance as it is free for undergraduates for one year; after that, the fees are small. Focus on the two largest meetings in March and April. The conference is a huge gathering of some of the best physicists in the world with special sessions for undergraduates with free stuff (but you should still attend the talks!).
Georgia Tech Society of Women in Physics – Our wonderful sister organization! They have great study resources, research info, and events of their own. They have regular gatherings in the Howey Interaction Zone on Tuesdays at 11am called Coffee and Conversations.
Georgia Tech Astronomy Club – For those who are particularly interested in Astrophysics, definitely check out the Astronomy club. They frequently go to the Fernbank Science Center, on weekend stargazing trips, and even work with our Observatory in Howey. They meet Mondays at 8pm in Howey L5.
