As I walked in classroom 101 at a University of Chicago Building, I really didn't know what I was getting myself into. I knew astronomy will be a main subject, and I was told iPad minis will be involved. The day began with introductions, and I was able to meet a couple new people from different schools. Majority of them have similar interests, such as science and math. Also majority of them entered the program with open minds, ready to learn something new. I learned a few things today. One thing I learned is that chemistry and physics coincide with one another. I learned about the double slit experiment (http://m.youtube.com/watch?v=Iuv6hY6zsd0&amp;desktop_uri=%2Fwatch%3Fv%3DIuv6hY6zsd0) scientists use to think that if a photon went through one slit it would cause a line of light to form. However when there were to slits and two photos shined through, an interference occurred. Light was said move in particles, however this experiment suggests light moves in waves. Day 1 at NASA All-Stars has taught me something already! I hope to learn more!!!!!
