## The Parabola Of a Football throw

The last Unit we had learned about Quadratic Equations. It is where there are four terms and you have to use it to find the parabola of the equation. For example a quadratic equation could look like y = x^2 + x + 1. Using our knowledge with these quadratic equations our assignment was to find a real world situation that would involve a parabolic motion.

Now you could say that math is everywhere, and it truly is. When we were looking for our parabolas it was very easy to find as it was everywhere. From the throwing of a ball to a dome-shaped object. Math is everywhere all around us.

The requirements for the assignment were that it could not be of a basketball shot since it was used as an example. Next, we had to have a scale (it has to be in exact size or distance) for the parabolic motion, the video could be of us recording the parabolic motion or a video from youtube. For me, I had used an American Football throw. The ball had traveled in a dome-like shape and had moved from left to right. The catch at the end was another parabolic motion, as if you focus on the center of the body you can notice or see that the body goes over and back. Once we had finished recording the parabolic motion we then had to analyze the video inside an application called Logger Pro. This application would use the scale and video then create a parabola based on the information given to it. How we create this parabola is that we first need to click all at the object or movement throughout all of the frames or just the selected frames.

Now this would help you or everyone else realize that math can be incorporated into anything. And also can be found anywhere.

## China’s Cultural Revolution

The journals that I had written had taken place during 1966-76 the Cultural Revolution. It is written in the perspective of a college professor at Beijing University. These journals talk about his journey throughout one of the main events in China. As he thinks everything is great and well, his whole world starts to change before his eyes.

China had been through a very intense revolution led by Chairman Mao. He had wanted to get rid of the 4 Olds, Customs, Habits, Ideas, and Culture. By doing so he would then establish the new. As he called to the working class the Red Guards began to form, and China then was in a state of civil war. But the higher class people would be punished and any relations to the higher classes would as well be punished. Even thought people thought of Mao as a very great leader, people around him started to disappear and or rebel against him. After the death of Mao, many of the things in China resumed to its original ideas before the revolution.
