Mirrors

After we went to the fair on Saturday, my friends and I rode the bus to Ala Moana. We walked around and ate dinner at Genki Sushi. And since my friend new one of the workers, our dinner was super cheap. It was awesome. After we walked to Nordstrom. In Nordstrom there was a big mirror. It made me think of a concept in physics. A planar mirror is a flat mirror that reflects light. The image in the mirror is the same size as we are and are equally far from the mirror. We appear behind the mirror. The mirror has a front-back reversal which means we are facing in opposite directions. The image of us appears right side up in the mirror.
Later, we left Ala Moana and went back to the fair to watch the talent show. It was pretty good. I'm sad because it is probably the last Family Fair I am going to go to since i am going to college.

Space Needle

Over spring break i went to Seattle. It was super dooper cold but it was nice. I visited Seattle University and ate at lots of good restaurants. I got really fat hehe but the food was really good. One of the restaurants we ate at was called Sky City which was at the top of the Space Needle. It was a rotating restaurant. This made me think of a concept we learned in physics. The restaurant is moving in a uniform circular motion which is movement in a circle at constant speed. When an object is moving in the circle, it has constant speed but the velocity chagnes. Centripetal acceleration is acceleration due to change in direction in circular motion. It is pointed toward the center of the restaurant and has a constant magnitude. Centripetal acceleration depends on speed and the radius of the circle. The restaurant was really nice but after I returned from the bathroom I would get really confuzed because the table I was at moved.
