Kinematics of a Fan (Impressive)
Wow. This is a breathtaking photo of my ceiling fan courtesy of my phone. Slight sarcasm aside and regardless of the quality of the picture, in photography this is called an action photo. It is categorized so because it captures motion. The blur of the blades of the fan was created because the blades were moving at a speed faster than my phone's shutter speed. This represents kinematics in physics because the fan was in motion; the blades had a speed. When fans are on, the blades travel a great distance, but they don't really go anywhere. What I mean is that the displacement is small because as far a distance as the blades travel, they never detach themselves from the fixed point in the center. (They never go flying across the room because they are attached at the center.)

Physics in the Photo
This is another photo that I took when I was in photography. It is one that I am especially fond of because it looks rather whimsical and maybe almost nostalgic. This represents physics because of what my friend, Maile, is unable to do--that is, she cannot fly with an umbrella. Unfortunately, she is no Mary Poppins or a magical being with no mass. Because of the pull of gravity on her, she cannot float away under the umbrella like a smaller creature might be able to. However, because of the gravitational pull on her, she is able to do everyday things like running, jumping, kicking, and rolling.

Introduction...
I'm Marisa. I enjoy doing things like playing tennis, making jewelry, and baking along with a few other things. Although I've gotten good grades in my past science courses in high school, they were during the summer and the lowest level. I'd like to think I'm not terrible with science, however, because I was admitted into the PSTP program at Temple University (although I quit after one year). Currently, I am in Honors Pre-Calc. From all of my classes, I hope to learn more of anything they can possibly teach me. The picture is of Luke, one of the two dogs that I keep. I took this photo for the photography class I took last year. It was a little challenging to get him to look at the camera, but I managed to get his attention by gifting him a dog treat. This photo represents the fact that I like creating things--anything.
